Bitumen roof. Mastic for repairing soft roofs using a cold method: bitumen for the roof. Bituminous mastic has different modifications

Bitumen roofing- modern and quality material, resistant to external influences. Unlike old types of coating, which can last no more than 5-10 years, current varieties demonstrate a significantly longer service life.

This occurs due to the use of a multilayer material, the basis of which is durable and load-resistant fabrics, and the binding layer is modified bitumen.

The advantages of such coatings include:

• strength, ability to withstand all operational loads
• durability - most materials last up to 30 years
• tightness, moisture resistance
• tightness of attachment to the base, which does not allow gusts of wind to tear off the covering fabric
• high sound insulation and heat-saving qualities
• maintainability, the ability to restore small parts without replacing the entire coating

The disadvantages of bitumen roofing are:

• most varieties require the creation of a substrate, which increases the cost of the entire roof
• appropriate conditions are required for installation. In particular, installation must not be carried out at temperatures below +5°C

The disadvantages of bitumen roofing are not so noticeable that users refuse to use it. The demand for the material is stable, and the wide selection allows each buyer to get the best option.

Roofing device: pie

Experts call a roofing pie a multi-layer package of materials laid under the finishing coating.

It usually includes:

• vapor barrier. Most often, this is ordinary polyethylene film
• heat insulator. Can be installed in soft or hard varieties mineral wool, foam plastic, sprayed types, etc.
• waterproofing or vapor waterproofing membrane. It is capable of transmitting water vapor in one direction, ensuring dry insulation

After these layers, a ventilation gap is installed, formed by slats. A continuous flooring made of OSB, plywood or other materials is laid on top of it. sheet materials. fits on it underlay carpet, after which the bitumen roof is installed.

There is another design option. If there is no need for insulation. Therefore, the composition of the cake is much simpler - continuous flooring is laid directly on the rafters, followed by an underlay carpet and a finishing coating.

Types of bitumen roofing, pros and cons, cf. price per sq. m.

The name “bitumen roofing” is a general name for a fairly large group of coatings. They all have their own characteristics and properties. Among them are rolled and piece types of material. The first include:

Rolled

Ruberoid

This is the oldest type of bitumen coating and is currently used only on outbuildings or to waterproof certain structures during construction.

Uniflex

It is a coating with solid foundation and modified bitumen as a binder layer. A layer of mineral coating is applied on top of it, which prevents the layers in the roll from sticking together.

Glassine

It is a type of roofing felt and is not used as a roofing sheet.

Bipole

The fiberglass base is impregnated with modified bitumen, resistant to ultraviolet rays. There is a layer of mineral coating on top.

Linocrom

This is a fiberglass base coated with laminated bitumen.

Piece

Bituminous shingles

Piece types of bitumen roofing include bitumen shingles. It is available in the form separate sheets(shingles), which are overlapped on the substrate and form a continuous and airtight coating.

A feature of bituminous shingles is their ease of installation and ease of installation on pitched roofs, which has significantly expanded the scope of application.

Prices

Prices for bitumen roofing are relatively low, but total price turns out to be quite high. Due to the need to install the substrate, the cost of 1 sq. m of coverage ranges from 400 ₽ to 3500 ₽.

List of types of bitumen roofing TechnoNIKOL

The Technonikol company is a leading supplier to the domestic market. Bituminous roofing is not the main, but very important part of the production. The range of materials is very wide and includes the following types:

• rolled materials (roofing felt, glassine, uniflex, bipol, linochrome)
• piece materials - bitumen

Flexible tiles are available in a wide selection of materials. They are combined into groups (collections) with several color options:

• Atlantic
• Continent
• Western
• Country
• Ranch
• Foxtrot
• Samba
• Rumba
• Modern
• Tango
• Quadrille
• Flamenco
• Salsa
• Bolero
• Chord
• Sonata

These collections differ from each other in the set color solutions and the shape of the cutouts on the sheets. There are rectangular, jagged, wavy and other varieties. In the canvas they form a peculiar roofing pattern, reminiscent of traditional tiles.

Repair and auxiliary materials

In addition to roofing coverings, the Technonikol company presents repair and auxiliary materials used during installation or restoration of the main covering. For example, bitumen mastic for roof waterproofing is used both for pre-treatment and in repair work.

In order to select the most suitable look bitumen roof, it is necessary to carefully analyze the conditions of its operation:

• temperature range
• solar intensity
• possibility of mechanical influences
• amount and intensity of precipitation. In particular, the amount of snow in winter period and frequency of cleaning
• wind strength, possibility of hurricane gusts
• complexity of the roof configuration
• other features

Taking these criteria into account, the most durable and resistant material to all expected impacts is selected. It is important to understand that roll fabrics are generally less stable than piece materials. In addition, flexible tiles are much more convenient to repair and are able to adhere tightly and firmly to the substrate.

An additional criterion will be the installation method. If you plan to install it yourself, you can consider more expensive materials, but if you hire hired installers, the cost of the coating will increase installation prices.

Installation and installation stages

Order installation work is described in detail in the manual that comes with the material. It must be carefully studied, since each coating has some features or nuances in installation. Procedure:

Preparing the base

The solid flooring must be cleaned of dirt, debris and dust. It is necessary to make sure that it is assembled correctly, that there are ventilation gaps and other necessary elements. If shortcomings are noticed, they must be eliminated immediately - then there will be no opportunity.

Laying underlay carpet

It is made parallel to the cornice line. On flat roofs or with a small angle of inclination it is mounted over the entire area. On roofs with large slope angles, they often make do with laying carpet only in the valleys, at the transitions of planes and other critical areas. Installation is carried out using roofing nails; all overlaps and joints are treated with bitumen mastic.

Installation of planks

Installation of end and eaves strips around the perimeter of the entire roof. They are nailed on top in a zigzag pattern.

Installing shingles

Laying shingles (sheets) starts from the middle of the cornice and goes to its ends. It is recommended to mix sheets from several packs together- this will help achieve uniform coloring of the entire roof.

The shingles (more precisely, their lower edge - the petals) are attached at a distance of 1 cm from the edge of the eaves and secured with roofing nails so that their caps are subsequently hidden by other sheets.

• the next rows are fastened so that the cutouts of the bottom row fall in the middle of the petals of the top. When the installation approaches the ends, the shingles are cut to size and glued to the eaves strips using mastic.
• laying the ridge part is done either with the same shingles with cut petals, or using metal or plastic ready-made elements from metal tiles

The installation procedure is simple, but requires accuracy and thoroughness. If the eye fails, it is recommended to make markings to guide the installation of subsequent rows of bitumen roofing.

Bitumen mastic

Bitumen mastic for roofing applied to joints, sheet overlaps or other critical areas. Sometimes it is applied as a continuous coating over the entire roof area. This makes installation more expensive, but provides high-quality waterproofing of the surface.

The material is poured onto a continuous floor and distributed evenly over the entire area. Before application, the mastic is thoroughly mixed in the container. If it is too thick, heating to a temperature of 60-80°C is allowed. Hot material must be used quickly, since when applied it quickly cools down and loses its fluidity.

Bitumen tape

Bitumen tape for roofing is a strip of material with an applied sticky layer, covered for the time being with a film. Used for sealing connections, protecting joints, insulation of the junction of the canvas to the eaves or wind strips.

This strengthens the coating and prevents the wind from tearing it off in a sudden gust. Another way to use it is to seal cracks, seams, and gaps during repair work. It is noteworthy that the bitumen tape does not have to be used in conjunction with bitumen coating, it fits on, ondulin, and other types of roofing.

Bitumen sealant

Bitumen sealant for roofing it is used for processing junctions, passage points through the roof and other critical areas.

The popularity of flexible tiles confidently rests on the traditional “three pillars” of low-rise construction. This is an attractive price, long-lasting coating and extremely simple installation technology.

An important advantage is the ability to handle the roofing of the roof with your own hands. Only for an impeccable result of the work you need to know how bitumen shingles should be laid on the structure being equipped, which should be taken into account during installation to form an ideal coating.

Flexible tiles are one of the varieties soft roof, manufactured according to the principle of rolled materials. In terms of technical and technological essence, it is a modified roofing material, improved in terms of strength, aesthetics, and wear resistance.

For ease of installation and shaping impressive looking it is cut into elements with a figured outer edge. They are called shingles, shingles or tiles, they are laid by analogy with wooden roofs according to the fish scale principle.

The same technologies are used in the production of flexible tiles as in the production of rolled bitumen-polymer roofing options. Several important layers take part in its structure, these are:

• Fiberglass. Serves as the basis for the specified roofing covering. It is fiberglass that provides high strength and resistance to chemical, atmospheric, mechanical, and biological aggression.
• Bitumen-polymer shell. It is fused to the top and bottom of fiberglass, directly forming the structure of the material and impeccable waterproofing protection. Oxidized and supplemented with polymer components, bitumen has practically zero moisture absorption.
• External mineral coating. Treatment with granulate on the front side of the roof creates the impression of expensive natural stone or copper plating. The second role is to protect the outer surface of the material from external negativity that occurs during operation.

The back side of the shingle tiles is sprinkled with sand or covered with a polymer film so that during transportation and storage they do not deteriorate by caking with each other. Before laying, the film or sand is removed in order to adhere to the base prepared for the roofing.

Many companies are now engaged in the production of various brands of flexible tiles, including both foreign and domestic representatives. Each manufacturer strives to make its own contribution to the process, to create a product with unique properties and technological advantages.

For some, the back side is completely covered with a self-adhesive bitumen compound that adheres the tiles to the base and to each other, while for others this substance is applied only in stripes. There are differences, but they are minor.

As a result of installation, the technology of which differs little from all manufacturers, all types of material under the attack of UV rays are sintered together into a continuous carpet and reliably glued to the base.

Pros of using asphalt shingles

Piece flexible roofing is produced in a wide variety of colors, textures, and decorative designs. In the abundant assortment, it is difficult not to find the material required for design.

In addition to the above priorities, justified by the manufacturing features, the pros and cons of bitumen shingles cut into tiles include:

• Unlimited technological possibilities. Using this type of material, you can equip a roof of any architectural complexity, regardless of the chosen configuration and size of the slopes. Roof tiles are easily mounted on onion domes and multi-faceted tent structures.
• Compatibility. The result of installation is in perfect harmony with the exteriors of low-rise and high-rise buildings, made in any of the currently popular architectural styles. Suitable for classics, antique styling, and newfangled design trends.
• Easy installation. After familiarizing yourself with the installation rules, you can install the roof using bitumen shingles yourself. When contacting builders, it is not necessary to hire a large team; a couple of people can easily handle the job.

It is impossible not to note the remarkable insulating qualities. Bitumen tiles, after sintering under the sun's rays, form a waterproof carpet that prevents all attempts of atmospheric water in any form to penetrate into the thickness of the roofing system. A flexible roof ideally dampens external noise interference, preventing external sounds from entering the furnished home.

Maintainability is rightfully considered a valuable advantage. If one or more adjacent shingles are damaged, there is no need to completely remove the roof and lay a new one; it is enough to replace the damaged part of the roof.

It is advisable to replace the damaged area with a material with a similar color and quality, for which it is recommended to stock up on a pack of material from the same series from which the entire roof is made. However, the appearance of a piece roof allows some deviations in color, so it is acceptable to use a slightly different color.

Disadvantages of bitumen piece coating

No matter how hard the developers and manufacturers of roofing coverings try, there is still no ideal option for roofing. Flexible bitumen shingles similarly have a number of disadvantages, including:

• Slope restrictions. The smallest slope angle for possible installation is considered to be 12º. Piece roofing is not suitable for flat structures, because... Before sintering the tiles, it has many holes that can let water through. They can cause seepage and prevent the tiles from bonding.
• Labor intensive installation. Despite the simplicity of the technology, installation will still require much more time than when arranging a roof with large-sheet material, for example, profiled roofing tin or metal tiles.
• Incompatible with conventional roofing felt. It is unacceptable to use traditional roofing felt as a waterproofing underlayment, which can “pull out” bitumen components from the roof covering, which ultimately leads to destruction and, in some places, swelling of the roof.

In addition, the working life of ordinary roofing felt is significantly less than its improved analogue, from which flexible tiles are made. It is unreasonable to arrange a base for laying the coating, which will serve less.

Step-by-step installation technology

The stages of work on the construction of a roofing system with flexible tile covering are carried out in a standard sequence for all types of roofing. First, the base is prepared, then markings are carried out, the material chosen for the arrangement is laid, and additional elements are installed.

The same steps are performed when installing bitumen shingles, however there are some technological subtleties, which we will now analyze.

Stage #1: Foundation preparation process

Flexible tiles are placed on a continuous sheathing constructed from edged or tongue-and-groove boards, moisture-resistant plywood marked FSF or OSB-3 boards. The material for the base must be consistent in thickness, which is especially important if a board is used.

In the construction of the sheathing, it is necessary to observe the technological gaps required to ensure linear expansion of the material in the event of moisture. “Gaps” of 3-5 mm are left between the boards and slabs. The board is laid along the eaves outline, starting from the lower edge of the roof.

The slabs are installed so that the result resembles brickwork, i.e. There should be no cross connections. It is permissible not to leave gaps or reduce their size if the sheathing is installed in the summer. The thickness of the base for the flexible coating is selected depending on the pitch of the rafters.

A waterproofing carpet is laid over the sheathing, for the installation of which you need to take the material recommended by the manufacturer of the type of bitumen shingles chosen for installation. It has already been noted that traditional roofing felt is not suitable for these purposes. In addition, if you use it, your roofing warranty will be void.

To design and strengthen the roof perimeter, waterproofing is installed in front of the waterproofing device. metal protection, This:

• Cornice strips. Installed in front of the waterproofing carpet. They are fixed to the sheathing, staggered at intervals of 10-15 cm. Galvanized fasteners with wide heads are used.
• End strips. Installed above the underlay waterproofing along the edge of the gable overhangs. They are attached in the same way.

The standard length of the slats, as a rule, is not enough for installation along the entire length. They are lengthened by simply applying the next similar element with an overlap of the previous 3-5 cm. Fasteners in this area are placed after 2 cm.

Stage #2: performing waterproofing work

Typically, manufacturers produce all the components for roofing themselves, including waterproofing underlays. They are made from a mixture of bitumen and polymer, but they are made thinner than the coating itself and do not use granules for sprinkling.

The specifics of the installation of a waterproofing lining depend on the steepness of the structure, if:

• The slope is within 12-18º. They install continuous waterproofing protection with preliminary fastening of backup waterproofing in areas where the likelihood of leakage is greatest, which includes all convex and concave corners of the structure, cornices, penetrations, and gable overhangs.
• Slope over 18º. Waterproofing protection is placed only on areas of possible leaks - those same curved and convex corners, i.e. in valleys, along hip and ridge ribs, along eaves, along gable overhangs and around the passages of communication pipes through the roof.

In the first case, a continuous waterproofing carpet is laid horizontal stripes, starting from the cornice line. Before laying it, strengthen the waterproofing problem areas self-adhesive water-repellent material.

The waterproofing itself is laid horizontally, in longitudinal panels, so that each overlying panel overlaps the previous one by 10 cm. As a result of this arrangement, the ingress of moisture into the roofing system. IN longitudinal direction overlaps are 15 cm.

In the second case, the insulation is glued in fragments. Self-adhesive tape is laid along the eaves and valley lines. roll material, along convex corners and along gable overhangs, it is permissible to use protection with less waterproofing properties, and stick a water-repellent lining onto bitumen mastic.

At the intersections of sewer, ventilation, chimney pipes and other communications, a 1 x 1 meter lining carpet is glued.

Stage #3: marking the roof before installation

Marking is necessary to speed up the installation process, facilitate and systematize the work of the roofer. At this stage, it is most convenient to think through and carry out adjustments to the roof, because Most often, there are still some deviations in the geometry of the slopes being constructed, both vertically and horizontally.

The markings are made with coated construction lace. The lines drawn with its help are not a strict guideline for roofers; they just outline the general direction and do not allow them to stray from it when performing installation work.

Lines are “drawn” along and across the ridge ribs. The longitudinal marking pitch is equal to the width of the bitumen shingles. Horizontal guides are beaten in 5 standard rows, this is approximately 80 cm.

When marking, you should decide at what point the flexible tiles will begin to be attached. It all depends on the length of the slope, on the shape and size of the figured teeth of the outer edge of the bitumen shingles.

On slopes of impressive length, the installation of shingles begins from the center. This makes it easier to align the row if there is a possibility that the piece roof will move horizontally. To correctly lay bitumen shingles on short slopes, you need to calculate in advance how many uncut elements will lie on the surface in order to reduce cutting.

Stage #4: installation of flexible tiles

Let's look at the procedure for laying bitumen shingles using the example of working with Shinglas material, a product supplied to the market by TechnoNikol. The assortment she offers includes materials of varying tones with symmetrical and asymmetrical external teeth.

Depending on the coating series, the tiles in their upper part are either glued to mastic or secured with an adhesive back. In the second option, there is no need to use mastic to fasten row tiles; just remove the protective polymer film and attach the shingles to the required location.

Each tile must be nailed. Row tiles are fixed to the prepared base with wide roofing nails that provide reliable fastening flexible material, hats. The number of fixation points depends on the steepness of the structure.

The nails are driven precisely perpendicular to the base; deviations are unacceptable. Place them at a distance of 2-3 cm from the edge. The serrations of the overlay cover and camouflage the attachment points of the underlying shingles, keeping them hidden from view and protected from rusting.

Before you start fixing the flexible tiles, lay the starting strip. It is used in finished form, specially produced for finishing cornices with ridges, or they can be made independently by cutting off the curly protrusions-petals from ordinary bitumen tiles.

Flexible shingles are laid offset in each subsequent row so that the overlying tab is just above the joints of the two underlying ones. It is necessary to shift, but there are no clear requirements for selecting a pattern; the main thing is to close the fixation points.

Regardless of the features of the series, it is customary to lubricate the outer tiles with bitumen mastic for a minimum of 10 cm. This is necessary to protect the roof from heavy rains.

Flexible tiles cover the entire surface of the slopes, not reaching the edge of the hip ribs and ridge ridge by 0.5 cm.

Stage #5: installation of valleys, junctions, ridge

Like any other type of coating, bitumen shingles require decorative and protective design. It will add aesthetic completeness to the roof, and also protect its edges from the penetration of atmospheric phenomena dangerous to the roof.

The valleys are arranged open and in a closed way. According to the first, the tiles are simply laid on top of the waterproofing carpet laid in the groove as usual. However, the edge of the tiles falling into the valley is not fixed or nailed, not reaching the axis of the valley by about 30 cm.

After laying the flexible tiles completely on adjacent slopes, two parallel lines are beaten with a coated cord, according to which the excess coating is trimmed. The distance between the lines is from 5 to 15 cm, depending on the slope of the slopes. Narrow gutters are installed on steep roofs, wide ones - on flat structures.

According to the second method, the tiles are first laid on a gentle slope, while extending onto the adjacent steep surface by about 30 cm. The upper corner of each laid tile is additionally secured with nails.

After arranging the entire slope, beat off the line of the upcoming cut with a coated cord. It is carried out at a distance of 7 cm from the axis of the groove. Flexible shingles are laid on a steep slope taking into account this line, cutting them during the fastening process. To improve the fastening of cut tiles in places that do not have an adhesive back, they are coated with mastic.

Junctions are arranged using wooden slats, loose along the length along the diagonal. Its wall size is 5 cm. A triangular strip is nailed along the line where the roof meets the walls, with a ventilation shaft, with a brick pipe, etc.

Before arrangement brick surfaces plastered and coated with primer. After laying the slats, glue the waterproofing carpet so that one edge extends at least 10 cm onto the vertical surface. The second edge is glued to the horizontal surface.

Metal strips are placed on top of the roof at the junction points, the top shelf of which is recessed into the brick wall by about 1.5 cm. To do this, select a groove, and after inserting the strip into it, the entire space in this “groove” is filled with a sealing agent.

To arrange the exit points of the antenna and ventilation pipes, specialized elements are produced that seal the passage. Their use greatly simplifies the work of the roofer and speeds up the procedure.

The arrangement of hip and ridge ridges is carried out using ridge-cornice elements, divided into three tiles along the perforation line. You can use regular tiles by cutting off the petals and then cutting them into three parts.

Before attaching the spine trim, its outline is traditionally beaten with coated cord. Tiles bent in half are placed on the side opposite to the prevailing winds in a particular area. Each previous one is superimposed on the next one. The overlap must be at least 5 cm.

As a result of fastening the spine tiles, their open part should be turned along the direction of the wind. So that the gusts do not “shag” the flexible tiles and seem to flow in his direction.

On hip roofs First, convex corners are arranged, the tops of which are covered with a ridge assembled from shingles. On roofs constructed in the described manner, ventilation is ensured by installing aerators.

If it is planned to construct ventilation through a ridge rib, then it is covered with a ridge aerator. Instead, two boards connected at an angle can be used, on top of which spine tiles are attached.

A visual guide to installing a roof made of flexible bitumen shingles will help you thoroughly understand the technology:

Bitumen coating deserves close attention of country property owners. It looks great, lasts a long time, and reliably protects the roof structure. The information we offer will help you conduct your own roofing works and in supervising a team of hired construction workers.

Soft roofing is one of the popular types of roof covering. It is successfully used both in the construction of private houses, outbuildings, and for multi-storey buildings. Materials of this group are made on the basis of bitumen and fiberglass. They have such advantages as: ease of installation, increased noise, hydro and heat insulation properties. In this case, even repairs will not require any special expenses. And you can do all the work yourself.

Roof repair documentation

When carrying out repair work on a soft roof, the following documents are used:

• estimate (work performance document). It takes into account all planned repairs on a given roof. For example, dismantling the roof, preparing the base, installing new material and sealing seams, creating a waterproofing layer. The estimate includes the cost of consumables and combustible materials, as well as the cost of their delivery. This document will help you estimate the budget for future repairs and decide whether to carry it out yourself or to allow specialists to do it;
• SNiP ( building codes and rules). During repairs, it is important to follow the requirements set out in the SNiP document “Repair of Soft Roofing” number 11-26-76. It lists everything necessary materials for waterproofing, types of mastic, roofing materials
• and requirements for the order of work;

PPR (works project). This document is important if repairs are being made to the roof of an apartment building. It indicates the rationale for the repair work, the results of the roof inspection, its characteristics, methods of organizing and methods of performing roofing work.

Types of damage and types of repairs

Soft roofing requires periodic inspection. It will help to identify any violations of the integrity of the roofing covering in a timely manner and carry out restoration work in a timely manner.

Common problems with soft roofs are:

Swelling of a soft roof may occur as a result of violation of the technology for laying materials

Moss on a soft roof appears as a result of improper installation technology

Delamination of the roofing material can be repaired by sealing the ends and strengthening the seam with a patch

Soft roofing may crumble after the end of its service life or under unfavorable conditions of use. It is recommended to regularly clean the roof of branches, debris and snow. These measures will increase the service life and minimize repair costs.

Depending on the type of damage, there are three types of soft roof repair work:

Local or current - involves the elimination of small defects in the roofing sheet.

Local repair of fused roofing ensures quick restoration of the coating at low cost

Major roof repairs involve removing the old covering and laying new material

Emergency repairs are carried out immediately after an unexpected violation of the roofing covering to avoid even bigger problems.

Soft roof bitumen

Soft roofing is found everywhere today. It is convenient to install, so its popularity is only growing from year to year. Soft roofing materials can be produced either individually or in rolls, made from various materials. Another undeniable convenience is that repairs, elimination of defects and the waterproofing process do not require large investments and time. However, first things first.

Features of a soft roof

This type of material is one of the five most popular in Russia. They cover bathhouses, cottages, garages and gazebos. Soft roofing is made on the basis of:

It is bitumen that makes it possible to easily solve problems in the form of defects, swelling, the appearance of fungus and other troubles. From time to time it is necessary to check the roof for its integrity and make repairs. We will tell you how to do this in our article.

In addition, the soft roof looks very attractive. Its light weight is also a plus. There is no additional pressure on the roof base, structure or foundation.

Possible problems during operation

To extend the life of a soft roof, it is necessary to inspect it twice a year for defects, the causes of which can be many. You need to pay attention to:

• peeling at joints;
• bloating;
• the appearance of cracks and other damage where water could accumulate.

Correcting problems in a timely manner will keep the coating in its original form and extend its service life. High-quality repair- the key to excellent roof waterproofing.

Repair of soft roofs is carried out using bitumen mastic. You can purchase it or make it yourself. In addition to repairs, bitumen can also be used:

• for roof waterproofing;
• for sealing seams;
• for carrying out anti-corrosion measures on a metal roof;
• for the production of soft roofing.

However, let's talk in more detail about repairs. The fact is that today the market is overflowing with various sealants and mixtures for repairing soft roofs. Anyone can get confused in this diversity. Let's say a defect is discovered that requires repair. What should someone who decides to immediately make repairs do? First of all, you need to choose the material.

Bitumen mastic as a material for roof repair

We suggest considering simple bitumen mastic as a material. Its advantages are as follows:

• it is an economical product;
• the material has been tested for generations;
• repairs are carried out quickly and efficiently.

Characteristics of the material and its advantages

Modified bitumen is a solution of two or more components. Let's look at the positive characteristics:

• increased elasticity and viscosity;
• resistance to oxidizing agents, alkalis and other aggressive materials;
• withstands elevated temperatures up to +100 degrees;
• not afraid of sunlight;
• withstands low temperatures up to -40 degrees;
• Easy to apply and light weight;
• has high strength;
• there will be no seams after application;
• meets all waterproofing requirements.

Thus, the material can be used on any type of roof: single-pitched, multi-pitched, flat, and so on.

Physical properties, especially increased elasticity, allow the hot solution to stretch, as needed by the master, and after hardening to shrink. There will be no unpleasant consequences from this. The consumption of mastic per 1 m2 is extremely small. It is believed that this is the most best quality solution. The problem with many materials that try to replace bitumen mastic is that when applied to a crack, they can break over time. The crack itself, under the influence of temperature, humidity and sun, even with mastic, will try to expand. Poor material will simply not withstand this stretching over time.

All mastic for repairing soft roofs can be divided into two types according to the method of its application:

• cold application;
• hot application.

In addition, today a huge amount of roof repair material is produced in the form of bitumen mastic with different compositions.

In addition to bitumen, the composition may include:

• rubber;
• isobutylene;
• polymer modifier;
• other additives.

In appearance, mastic is a black homogeneous mixture in the form of briquettes, paste, liquid or thick glue. Depending on the form in which it is produced, the method of its use and the material consumption per 1 m 2 change.

Manufacturers, in turn, also divide all mastic into four types:

1. Polymer cold application (used for almost all types of repairs, including anti-corrosion treatment).
2. Roofing (used for waterproofing, but the name itself comes from the method of use when applying rolled roofing material to the roof).
3. Rubber for cold use (for repair work and sealing joints).
4. Adhesive (functions similar to those of roofing mastic).

Compositions various manufacturers differ, however, the main component remains unchanged for many years. This is modified bitumen of petroleum origin. For increased elasticity, latex and synthetic-based resins are used. The resulting ductility affects the material consumption.

Additionally, one cannot help but mention the disadvantages of bitumen:

• liquid bitumen can leak, so many manufacturers add various modifiers to its composition;
• in severe frost (below 40 degrees), the material may crack.

To prevent the formation of cracks, special compounds supplemented with additives are used for roofing work in the north of the country. This must be indicated on the label.

Selection of mastic for repair work

When making your choice, carefully study the label. Good material must be manufactured in accordance with GOST 30693-2000 or GOST 14791-79. Regardless of whether the bitumen in front of you is modified or not, you need to check a number of parameters:

• density should be in the range of 1000-1100 kg/m3;
• the expiration date must be indicated on the packaging;
• the seller must provide a quality passport and a certificate of conformity;
• The drying time is indicated provided that the window outside is +25 degrees (standard is 24 hours, but if this time is less, it means that very little solvent has been added to the modified bitumen, which is not very good).

Consumption per 1m2 is also important for savings. Another question that worries buyers is whether to buy cold or hot mastic? Let's understand the difference between them.

Cold mastic is ready for use. The manufacturer may insist that it needs to be heated slightly, but the maximum temperature will be 40 degrees. It is good because it reduces the time of repair work and is not afraid of moisture. If it has recently rained and the roof has not yet dried completely, you can pour cold mastic to eliminate leaks, waterproof, and repair soft tiles.

The hot-applied material is very good, but requires compliance with safety regulations. The temperature reaches 150-200 degrees.

In addition to purchasing ready-made material, you can make liquid hot bitumen yourself.

Self-cooking

To prepare the solution you will need:

• old metal bucket;
• materials for lighting and maintaining a fire;
• bricks;
• bitumen;
• gasoline (if necessary);
• a strong wooden stick for stirring.

First you need to make a fire. Now, hang a bucket over it and put bitumen in it. The material will slowly melt when exposed to high temperatures. The mixture needs to be stirred from time to time.

If the mastic turns out to be very thick, gasoline is added to it. The consumption of the final product will be small.

Process self-made and application is shown in the video.

Repair work

Depending on what a visual inspection of the soft roof shows, repairs are divided into:

• emergency (waterproofing process in the presence of leaks);
• small (sealing cracks and seams);
• capital.

For minor repairs, small pieces of roofing felt, soft tiles or other material are needed. First the crack is filled liquid solution, then glue a piece of roofing felt, squeeze everything together and apply a new layer of bitumen on top. For such work, the material consumption per 1 m2 is minimal.

Emergency repairs require high-quality waterproofing. In case of leaks, it is necessary to apply mastic under the roofing material, first drying the area with a burner. The same method is used when the seams of a soft roof diverge. The consumption in this case is also small.

Major repairs are the most difficult of all; bitumen consumption here needs to be increased. The process itself can be divided into three stages:

1. the damaged sheet is removed from the roof;
2. prepare modified bitumen according to the instructions;
3. a layer of waterproofing (special material) is lined;
4. Using a solution, the roof is again covered with roofing material.

In cases where water is retained on the roof, it is filled with water without a sheet and this area is marked. After this, the liquid is distilled off, the surface is dried and modified bitumen is applied, followed by roofing material 1 millimeter thick. Now you can cover the roofing material.

Bitumen mastic is an excellent material. Low consumption, efficiency, ease of use and high quality waterproofing has provided it with an impeccable reputation.

Cold-applied bitumen mastic for waterproofing and gluing roofing felt: consumption and technical characteristics + Photo

This article will help you understand what cold-applied bitumen mastic is. What is the difference between cold and hot mastic. Where is it used? How to choose the right material based on properties and qualities for the required work.

Bitumen is a hard resin, and mastic is made from it. In order for the material to become plastic, its temperature is increased, which significantly increases the work time and has an obvious drawback - the risk of fire.

For this reason, it is much more convenient to use cold applied mastic. Thanks to the solvents present in the composition, the waterproofing material is in a liquid state and does not require heating for use.

Hot and cold mastic used to achieve complete waterproofing. The solvent evaporates and the material hardens. The result is a high-strength waterproofing layer.

General information about bitumen mastic

There are two types of cold applied bitumen mastic

First view

Manufactured using solvents. These are completely ready-to-use mixtures. Solvent-based mastic is suitable for use at sub-zero temperatures.

This type of waterproofing sets within 24 hours. It takes a week for the mastic to completely harden and acquire waterproofing properties.
Typically this type of material is used in roofing work.

The second type of bitumen waterproofing coating

Manufactured at water based– which characterizes the material as not harmful to the environment.
The coating does not have a strong odor and dries in a couple of hours.

Water-based waterproofing cannot be used at low temperatures. The material should also be stored in a warm room.

Bituminous mastic has different modifications

Unmodified waterproofing. The composition does not contain polymers or other components that increase the properties of the material. This type is not suitable for roofs; it is ideal for foundations. The waterproofing used for the foundation does not experience atmospheric overloads.

It is not recommended to use mastic without polymers for roofing work.

Bitumen- polymer mastic . From the name of the material it is clear that this type of waterproofing is characterized by high performance. Perfectly adapted to a wide temperature range. Very good molecular bond (adhesion), which allows the mastic to be used for gluing roofing felt and similar materials.

Due to its properties, bitumen-polymer mastic is widely used for covering flat roofs.

Bitumen-rubber mastic. The composition contains rubber crumbs. It has decent anti-corrosion properties. Used for coating metal structures.

Bitumen-rubber mastic is NOT suitable for roofing work.

Bitumen-rubber waterproofing, aka liquid rubber - very elastic with high physical and mechanical properties. These qualities increase the wear resistance of the coating. Perfect for roof covering.

Rubber mastic can become an independent roofing covering. Practically not subject to atmospheric influence.

The type of mastic is directly related to the components it contains.

One-component – ​​ready-to-use coating.

Two-component mastic requires mixing with a hardener before starting work. Used for professional purposes. Has good performance.

When using a two-part mastic, it is IMPORTANT to follow the mixing instructions exactly. Incorrect proportions will lead to an increase in hardening time.

The main advantages of cold-applied bitumen mastic

• Reduces waterproofing work time
• The mastic can be diluted with a solvent, which will make it the desired consistency
• Service life more than 25 years
• The coating can be used on surfaces made of different materials
• Easy to apply.
• Independent use

Disadvantages of this material

• High price.
• Bitumen-polymer mastic gives greater shrinkage, which affects material consumption.

Application

Cold application bitumen mastic material consumption:

1. For gluing 0.8 – 1 kg per square meter
2. For a waterproofing layer 2 – 3.8 kg per square meter

There are two leading manufacturers on the market:

1. Bitumen mastic TECHNONICOL
2. Bitumen mastic EXPERT

Both manufacturers meet all requirements. There may be differences in prices. And some nuances, such as material consumption and drying time.

Important to remember. Before using mastic, it is necessary to clean the surface of debris and dirt. The area to be treated must be dry. If the surface is porous, it must be pre-treated with a primer.

Bitumen mastic for roof

In construction, bitumen-based building materials are now often used. In particular, bitumen roofing, bitumen roofing tape, as well as various polymer-bitumen based sealants.

Bitumen mastic for roofing is widely used - it is made on the basis of bitumen, it allows you to simply and efficiently carry out waterproofing and roof repairs. Roofing mastics are well resistant to aggressive environments. One of their main advantages is that they can stretch and shrink without any consequences, are applied evenly to the roof of any configuration, and the work is performed seamlessly. Thanks to these properties, the coating is reliable and durable.

Bitumen mastics used for roofing work are of the following types.

Cold application

bitumen mastic expert

Cold bitumen mastic is a ready-to-use composition, although if necessary it can be diluted with various solutions. It can be applied even to a wet coating, which allows you to carry out work without special preparation and in the shortest possible time.

Hot application

Water based

They are the most environmentally friendly, because the content of toxic substances in them is minimal. They are easy to use and safe.

Bitumen mastics with special additives and fillers (plasticizers, minerals, etc.) have any specific properties:

Rubber mastic and polyurethane are the most elastic; they contain rubber or polyurethane.

• Bitumen-latex - very durable with increased water resistance, contain synthetic binders and mineral fillers (latex, asbestos, mineral wool fibers, modifiers).
• With an oil solvent - it does not harden, it is usually used on objects with constant vibration.
• Rubber-bitumen - resistant to stretching, shock and vibration, easily adheres to any surface.

Rubber-bitumen mastic is most often used for cars, but it is also successfully used for repairing roofs.

Now let's look at the use of various types of bitumen mastics for roof repairs.

Soft roof repair

Repair with a patch. Bituminous roof mastic is usually applied manually using a spatula or brush, sometimes with a spray. The surface of the roof to be repaired is cleared of dirt (rust or old paint does not need to be cleaned) and covered with mastic, then a patch is applied. For the patch, you can use bitumen tape, tarpaulin, etc. The patch must be pressed tightly to the surface so that there is no air gap left. You can also apply a protective layer of mastic on top.

Roof repair using bitumen mastic and roofing tape. Bituminous roofing tape is usually used to repair soft roll roofing. This tape is multi-layered - has a protective layer of aluminum foil, a layer of bitumen with plasticizers and a layer of polyethylene film. It adheres well to various materials. Good quality tapes do not contain harmful chemical additives, are tear and puncture resistant, and their protective reinforced surface is resistant to contamination, acids, alkalis and other aggressive environments. These tapes are very easy to use and do not require special skills to use. Let us examine in detail the repair method using bitumen tape.

bitumen mastic for repairing soft roofs

First you need to clean the leak area and the area around it from dirt, rinse thoroughly with water or a cleaning solution, and let it dry completely. Lubricate the leakage contour with bitumen mastic or primer. Next: remove the protective film from the adhesive side of the tape. Then, using a pressure roller, fix the tape on the roof surface and cut it along the edge.

Repair using flashing method. The roof surface is cleaned, treated with a primer, degreased if necessary, cracks are sealed with moisture-resistant cement-based putty. Next, two layers of mastic are applied, then reinforced geotextiles are laid and a protective layer of mastic is placed on top.

Hard roof repair

Repair of corroded areas. Hot mastic is usually used to repair hard roofs. First you need to remove the rust, clean the surface of dirt, then apply a layer of hot bitumen mastic.

Repair with a patch. First, we prepare a patch of the required size from a dense material (tarpaulin, burlap), then we impregnate it with a mastic composition and fix it on the place to be repaired, leaving it to dry well. Then apply another layer of mastic on top. This method is good for sealing interlocking surfaces.

Approximate consumption of bitumen mastic per 1 m

The consumption of mastic depends on its type and is often indicated in the description of the composition.

Hot applied mastics do not shrink much. To apply bitumen mastic in a layer about 2 mm thick, approximately 2.2 kg/m2 of composition will be required.

Typically, ready-to-use mastics shrink, and to create a 2 mm layer you need about 3.6 kg/m2 of composition.

bitumen mastic consumption per square meter

If necessary, to reduce consumption, the composition can be diluted slightly. So how to dilute bitumen mastic? You can dilute bitumen mastic with white spirit, solvent, toluene, kerosene, etc. For safe dilution, you need to carefully read the manufacturer’s instructions for working with the composition.

Bitumen sealants for roofing

In some, especially problem or hard-to-reach areas of the roof, it is better to use specialized sealants to better achieve the waterproofing effect. Bitumen roofing sealant is a special viscous composition made from modified bitumen. It is quite toxic and is used only for outdoor use. It is well resistant to moisture, ultraviolet radiation, various oils, solvents, and gasoline. Bituminous sealant is applied at temperatures above freezing, usually in several layers. For roof repairs on small surfaces, rubber-bitumen sealant is well suited, since it is vapor- and waterproof and very elastic.

Thus, to summarize, we can say that bitumen is widely used for roofing work because it has very good performance and consumer properties. Bituminous materials of the required type can be easily purchased in a store or made yourself. Their use does not require complex preparations, special tools or extensive experience. However, when carrying out repair work, you should still pay some attention to their choice. Sometimes different kinds roofs may have their own specifics. If you find it difficult to choose materials for repairing your roof, then it is better to use only universal, high-quality products. New materials allow roof repairs to be carried out quickly and efficiently.

Cold application bitumen mastic - the main points you didn’t know about

What is cold bitumen mastic? How does it differ from hot, and for what purposes can it be used? I'll tell you about the main properties of this insulating material and the scope of its application. This will allow you to independently choose the most suitable waterproofing option for yourself.

Cold application bitumen mastic is a universal modern waterproofing material

What is the material

General information

Bitumen mastic is a plastic material made on the basis of bitumen. The latter is a solid resin. Therefore, the bitumen-based mixture is heated before use.

Hot applied mastics are not very convenient to use. The need for heating increases the time for waterproofing work and also increases the fire hazard.

Therefore, in Lately Cold-applied analogues are more popular. They contain solvents, as a result of which they are sold in liquid form and do not require heating.

In the photo, cold applied mastic is a liquid waterproofing material ready for application.

The principle of action of such compositions is similar paint and varnish materials- after application to the surface, the solvent evaporates and the coating hardens. As a result, a durable waterproofing layer is formed.

Compound. Cold applied bitumen mastics, depending on the composition, are divided into two types:

• Solvent based. Ready-to-use mixtures that can be worked with even at sub-zero temperatures.
  The coating dries a day after application. True, the material acquires its final properties only a week after application.
  Typically, solvents are used in the manufacture of roofing mastic, but this waterproofing material can also be used for other purposes. I will tell you more about possible use cases below;

Water-based bitumen emulsion mixture is environmentally friendly

• Water based. This cold applied mastic is an aqueous emulsion. Thanks to this, it is odorless and environmentally friendly.
  In addition, water-based coating dries faster - it usually takes several hours. True, it can only be used at above-zero temperatures, the same applies to storing the material.

Modifications. Depending on the initial components that are used in the composition, the material in question is divided into the following types:

• Not modified. These coatings do not contain polymers or other improving additives. Therefore, they are not recommended for use for roofing, but at the same time they are excellent for waterproofing foundations, where they are not exposed to strong temperature changes and heating;

The unmodified composition can be used for foundation waterproofing

• Bitumen-polymer. Bituminous roofing mastic is usually modified with polymers. It tolerates heat and temperature changes well.
  Another positive quality is increased adhesion. Thanks to this, the composition can be used for gluing rolled materials;

Bitumen-polymer coating is not afraid high temperature, which allows it to be used for waterproofing flat roofs

• Bitumen-rubber. They differ from the addition to the composition crumb rubber. As a rule, they are used for waterproofing metal building structures, as they have good anti-corrosion properties. This waterproofing material is not used for roofs;
• Bitumen-rubber. This coating is characterized by increased elasticity, as well as excellent physical and mechanical properties, which is why it is also called liquid rubber. Such compositions are excellent for roof repairs.
  Moreover, thanks to high efficiency, durability and weather resistance, they can be used as independent roofing.

Before applying a waterproofing coating, regardless of its type, the surface must be carefully prepared - cleaned of foreign debris, dust and dirt, and then thoroughly dried. In addition, it is advisable to pre-apply a bitumen primer.

Depending on the number of components, bitumen coatings are divided into two types:

• One-component. They are a completely ready-to-use coating;
• Two-component. Must be mixed with hardener before use. These compositions are professional and have higher characteristics.

When mixing two components, it is extremely important to maintain the correct proportions, otherwise the drying time of the coating may increase dramatically. Instructions for mixing the components are available on the packaging.

Basic qualities

As I said above, unlike hot bitumen mastic, the analogue for cold application is convenient to use and speeds up waterproofing work. But besides this, it has many other advantages:

• Possibility of obtaining any consistency. To do this, add to the composition required amount solvent;
• Durability. This quality applies primarily to modified compounds whose service life exceeds a quarter of a century;

Modified bitumen mixture can last on the roof for more than 25 years

• Versatility. Mastic can be used to waterproof a wide variety of surfaces;
• Easy to apply. The coating is easily applied with your own hands using a roller, spatula or brush.

Flaws. The only downside is the higher cost; bitumen-polymer mastic is especially expensive. In addition, this waterproofing shrinks more strongly than its hot-applied counterpart, which increases its consumption.

Mastic consumption depends on the type of work. Bonding usually requires 0.8 to 1 kg/m2 of coating per square meter. To create a waterproofing layer per square meter it takes 2 to 5 kg of composition.

Bituminous shingles are a roofing covering made from individual sheets (shingles). It is waterproof, not subject to corrosion, and not exposed to UV rays. The material is laid on a solid flooring made of plywood or OSB-3 using underlay carpets and other accessories.

Structure

Flexible roofing - multilayer material:

• fiberglass It is the basis and reinforces the bitumen layer. Does not increase the weight of the material, does not rot, is not subject to corrosion;
• bitumen layer. Impregnates fiberglass on both sides, using a compound with improved properties. It is more resistant to temperature loads, retains elasticity longer and does not crack;
• the outer covering is formed by shale or basalt granules. They are painted in different colour, during production, they are poured in an even layer onto heated bitumen and pressed into it. Granules of different colors form a coating pattern;
• on inner surface An additional adhesive layer can be applied. It increases the reliability of installation and improves the fit of shingles to the base.

Types of bitumen

The characteristics of the bitumen layer determine the durability of the flexible roof and its resistance to temperature loads. Natural bitumen becomes brittle when cooled and melts when slightly heated. Additional processing of the compound eliminates these disadvantages:

• oxidation: saturation of the molten compound with air with the additional use of catalysts. Slows down the aging of bitumen, increases its plasticity, and increases temperature resistance. Oxidized bitumen is used for economy series of soft roofing;
• the use of SBS polymers in the bitumen compound: greatly increases the temperature resistance, elasticity, and durability of the material. With this modification, the property of self-healing appears: minor damage to the bitumen layer disappears over time on its own, without repair;
• modification with APP polymer: used in the production of flexible tiles abroad (in the Westmet catalog these are Tegola materials). APP polymer is elastic, heat-resistant, and has stable characteristics. Its use increases the operating temperature range of bitumen shingles and allows for their installation at subzero temperatures.

Bituminous shingles can be one-, two-, three-layer. The more layers there are in the coating, the more voluminous and expressive it looks, and the longer it lasts. At the same time, as the thickness of the material increases, its weight also increases, which must be taken into account at the construction stage. rafter system.

Advantages of a soft roof

• Weather resistant. Does not fade in the sun, does not allow moisture to pass through, and is resistant to temperature changes.
• Strength. It is not destroyed by impact loads, and is not damaged by falling branches, debris, etc. onto the roof.
• Acoustic comfort. Reduces the level of noise penetrating into the premises under the roof from the street.
• Maintainability. Damaged shingles can be replaced without removing the entire roof covering.

Questions and answers

• What kind of base is needed for bitumen shingles?

  Bituminous shingles are laid on a continuous flooring, additionally covered with a lining carpet. It is assembled from dried boards, OSB boards or moisture resistant plywood. Westmet engineers believe that it is more convenient to use FSF plywood or OSB - it is easier to assemble a flat base from them. The thickness is calculated according to the pitch of the rafters, according to total weight materials. For OSB minimum thickness- 9 mm, but it is better to use 12 mm plates (they hold the fasteners more securely). When using boards, the flooring must be treated with fire protection and dried well before laying the covering.

• How much does a flexible roof weigh?

  The average weight of 1 m 2 of single-layer bitumen shingles is 8-9 kg for the laid material. A two-layer coating weighs almost twice as much - 17 kg per 1 m2, a three-layer coating - 24-25 kg/m2. When calculating the load on the rafter system, the weight of the solid flooring (about 7-8 kg/m2 when using OSB boards 12 mm thick) and the underlay carpet (about 1 kg/m2) are additionally taken into account.

• What affects the service life of asphalt shingles?

  Flexible roofing lasts from 15-20 to 60 years or more. Its durability is affected by:

  • bitumen used: SBS- or APP-modified compound retains elasticity longer compared to oxidized;
  • quality of installation: installation using underlayment carpet, with reliable fastening, high-quality waterproofing and ventilation of the roof increases its service life;
  • number of layers in the shingle composition: the more there are, the thicker the coating and the more reliable it is.

• What is the difference between single-layer and multi-layer flexible roofing?

  The coatings differ in the structure of the shingles: when making a two- or three-layer material, several of its layers are glued together. It becomes more voluminous and more accurately imitates natural coatings, better protected from mechanical damage, its service life is longer. The weight of a multi-layer flexible roof is increased compared to a single-layer roof (the difference is a multiple of the number of layers), and this may require reinforcement of the rafter system and a solid base.

• Why do you need an underlayment for asphalt shingles?

  When installing a flexible roof, the lining carpet is laid over the entire area of ​​the slopes or along their perimeter, at joints, and in areas where the risk of leaks is increased. It provides additional waterproofing of the roof, levels the solid base, and improves the quality of installation. Flexible tiles laid using it last longer and look neater. Often, when using it, manufacturers provide an extended warranty on the coating.

Soft roof structure

The standard base for shingles is fiberglass. IN in some cases it is made from cellulose. One more mandatory element is bitumen (natural or modified). Thanks to the addition of polymer components, shingles acquire additional strength and elasticity. The outer layer of the soft roof is basalt granulate. It performs several important functions: it forms the color of the coating, and also protects the tiles from damage, weather influences and ultraviolet radiation. The inner layer is usually a polymer self-adhesive film or quartz sand.
