Glue for working with roofing material is a homogeneous adhesive mass, which is made using the technology of a multicomponent mixture. The basis for the manufacture of this adhesive are components such as:

• Bitumen;
• Solvent;
• Technical filler;
• Technological additives.

There are two types of mastic - the so-called hot and cold. From the name itself, it is obvious that the use of cold mastic is possible with a short warm-up and mixing with a solvent, and hot mastic must be brought to the required temperature before application, which should be on average about 200 degrees Celsius and such a mass is cooked much longer.

The use of the described mastics is possible when waterproofing floors, walls, foundations and other elements of buildings and structures.

Advantages of using bituminous glue

The use of bituminous glue is considered to be the most reliable and effective way arrangement of waterproofing from roofing material. The main advantage of using mastic over other methods of fixing roofing material is the absence of air pockets when connecting the joints of rolled material. Mastic allows you to achieve a solid monolithic waterproofing sheet, which will serve for a long time without the risk of damaging the edges and joints of roofing material sheets.

However, it should be noted that hot and cold mastics differ significantly in the price range. The price of bituminous glue for roofing material, which belongs to the cold category, will be much higher, since this type of mastic is ready to use and does not require long preparation.

How to glue roofing material on cold or hot mastic?

Before how to glue roofing material on cold or hot mastic care must be taken to keep the work surface clean. The presence of construction debris, dust or other third-party objects on the treated area is unacceptable.

You also need to take care of personal protection when working with bituminous glue - use gloves, a respirator and goggles. If the upcoming work involves being indoors, and not on outdoors, then it is necessary to take care of its effective ventilation.

Before gluing the roofing material to the working surface, it is necessary to prime it to increase the strength of the base and improve adhesion.

On average, the consumption of mastic should be 1.5 - 2 kg per square meter. m. This indicator depends on many factors, however, non-compliance with the norm can significantly affect the quality of work.

To apply bituminous adhesive, a notched trowel with 4 mm teeth is usually used, and for hot mastic, the consistency of which is too liquid for a trowel, special brushes can be used, with which the adhesive is evenly applied to the work surface.

You can buy cold mastic for roofing material in any specialized stores. At the same time, attention should be paid to compliance with GOST of the mastic manufacturing technology, the integrity of the factory packaging and the deadline for use. The average shelf life of bituminous adhesive is about 12 months, so when determining the required quantity, you should carefully consider the calculation of the required volume. To date, there are varieties of bituminous adhesives, which, thanks to unique technologies, can be used on wet surfaces or on surfaces with aggressive chemical environments.

Ruberoid has long been widely used not only as a waterproofing layer in the overall roof structure, but also as the main roofing material. Its use for roofing is especially relevant in cases where the need to create or repair a roof is very acute, and the owner of the house is short of money. It is also suitable for outbuildings that are invisible to the outside eye. In any case, if you have to resort to using such material precisely as the main roof, then the question arises - how to fix the roofing material to a wooden roof and other foundations.

Most often, gazebos, as well as outbuildings are covered with this roofing. But, in fairness, it should be noted that high-quality roofing material has no less operational resource than some modern roofing materials. However, how long it will be able to reliably protect the building from external atmospheric influences will depend not only on right choice coating, but also from compliance with the technology of its laying on a certain basis.

Varieties of roofing material and its scope

The process of choosing this roofing material must be approached with the utmost responsibility, since there are many varieties of it on sale, and it is important to choose exactly the option that is ideal for flooring on a wooden roof base.

Roofing material can be made on the basis of roofing paper or fiberglass, which are impregnated with refractory bitumen on both sides. Many types of such rolled material can have a protective coating on the outside in the form of medium or fine abrasive chips.

Roofing material of different types has its own marking and its own performance characteristics, depending on which it can be used in a particular area of ​​construction, as well as in different qualities, that is, as the main roof or only to create an additional one for it.

The main types of materials hiding under the term "roofing material"

Consider a few various materials, which are usually called the general concept of "roofing material":

• Tol- this is a rolled material that has been used for a long time and enjoyed wide popularity, but only due to the fact that there was simply no wide variety of waterproofing and roofing coatings in hardware stores. It is interesting that the name itself, apparently with a certain amount of irony, is borrowed from French: the word "tôle" means sheet metal roofing.

Tol is made on the basis of roofing paper, which is impregnated with tar shale or coal products, and is used as a waterproofing and roofing coating. However, only in comparison with other rolled materials, which are referred to as "roofing material", it has significantly lower performance and durability, and is most often used in the arrangement of temporary buildings that are not designed for a long period of use. At present, manufacturers have almost completely abandoned the manufacture of this material due to its impracticality - more modern and durable analogues have come to replace it.

• "Steklomast" It is made on the basis of high-strength fiberglass fabric or polyester fabric, which are impregnated on both sides with bitumen-polymer compounds. The outer side of this roofing may have protective layer, consisting of coarse-grained mineral dressing. Due to the qualities of these materials, the sheets of this waterproofing and roofing coating have high flexibility, which is not lost even at low temperatures.

The service life of this roll material, declared by the manufacturer, is usually about 15 years.

Prices for roofing material

ruberoid

• "Rubemast" - this is a modified version of the traditional roofing felt, which differs modern technology production and improved performance. The basis for this material is roofing paper, which is impregnated with special bitumen mixed with mineral additives.

Granite chips or quartz sand are used to sprinkle the outer side of the paintings. Thanks to production innovations, the density of Rubemast exceeds that of a conventional roofing material by almost 5 times.

• "Euroruberoid" It is made on the basis of fiberglass, which is impregnated with a mixture of bitumen and synthetic rubber. Rubber components significantly increase the waterproofing qualities of the material and make it more elastic. Therefore, "Euroruberoid" is well resistant to low winter temperatures, and its durability under conditions of constant operation is 20÷30 years.

The upper mineral dressing of the material serves not only to protect the lower layers from mechanical influences, but also performs decorative functions, since stone or sand chips of various colors can be used for it.

It should not be assumed that the name "Euroruberoid" means exactly the import production of the material. It is rather a "collective image", more talking about high quality such roofing. And it can also be produced here: a vivid confirmation of this is the widest range of high-quality rolled materials of the TechnoNIKOL company.

• Another version of the roofing material is its liquid variety, which is a polymer-bitumen composition (PBC) and serves mainly for waterproofing roofs. For use on concrete, wood and metal surfaces, as well as on old bituminous coatings during their repair.

The advantages of "liquid roofing material" include the fact that after drying it forms a seamless monolithic coating which will reliably protect the roof from leakage.

The mixture has high adhesion with any surfaces and is applied in two to three layers, with time intervals of one to two hours. Complete drying of the coating occurs in a day.

The advantages of all types of roofing material include the versatility of the material, as it is suitable for covering roofs installed under different slopes, and having various designs. It is not difficult to lay roofing material on your own, since it is not particularly heavy and has good elasticity. When repairing a roof with a ruberoid roof, you do not have to dismantle the entire coating - it will be enough to remove only the damaged area, and then lay a new sheet.

Mineral toppings of roofing material

A few words need to be said separately about the outer top coating of the material in order to give a general idea of ​​\u200b\u200bwhat it is like. As is known, apart from smooth surface, roofing sheets can have four types of protective coatings made of mineral materials - these are coarse-grained, fine-grained, scaly and dusty.

• Coarse-grained coating is made from mineral stone chips, and granite is most often used for this purpose. Roofing felt, having such a topping, is considered universal, as it is suitable for both roofing and waterproofing roofs or other building elements. But its main purpose, of course, is the creation of a high-quality roofing that is not afraid of external mechanical loads.

• The outer coating of cloths made of fine-grained powder resembles coarse-grained sandpaper, as it most often consists of quartz sand. This variant of the material is suitable both for the outer layer of the roof and for laying under another roof covering, as a basic waterproofing.

When making the roof of outbuildings and garages, an inexpensive, but very popular material, roofing material, is often used as roofing. Most often it is used to cover roofs with a small angle of inclination, that is, where other types of coating cannot provide good waterproofing. A do-it-yourself roofing felt roof is quite feasible, you just need to understand the laying technology and the characteristics of the materials.

The roof covering with roofing material always has several layers, and the lower layers are made of lining roofing material that does not have a protective layer, and the last top layer is made of roofing material with dressing. Roofing material dressing has a different size of the fraction, the resistance of the roofing material to damage depends on the size of the particles.

Ruberoid brands: how to understand them?

First of all, you need to understand what this material is. The traditional roofing felt, which has long been known to us, is a rolled material made of thick cardboard, impregnated with bitumen, with a denser top layer, smooth or sprinkled. More modern modifications of roofing material can be made on the basis of fiberglass, which provides additional strength and water resistance of the material. The so-called euroruberoid has, in addition, a floating polymer layer, which, when heated, forms a viscous surface that ensures the adhesion of the roofing material to the base. Euroruberoid does not require applying mastic between layers.

The traditional roofing material has an alphanumeric marking indicating its purpose and specifications. For each layer of coating, it is necessary to choose the appropriate roofing material.

The first letter in the marking is always "P", it means the type of material - roofing material. The second can be "K" - roofing, or "P" - lining. The third letter in the marking indicates the type of the top layer: "K" or "M" - coarse or fine-grained, "Ch" - scaly, "P" - pulverized. It may also be marked "E" - elastic. The numbers in the marking indicate the density of the cardboard in grams per square meter. For the lower layers of the roof, roofing material of the RPP or RPE brand is chosen, for the upper layer - RKK, RKM, RKCh, RKP. The built-up roofing material is marked RM and RK, respectively.

Determining the number of layers and calculating the material

The number of layers of roofing material to create a reliable coating depends on the slope of the roof and the possible snow load, as well as on the reliability of the roof itself and its ability to withstand the weight of roofing material and bitumen. The smaller the slope of the roof, the more layers of roofing material are required to make an airtight waterproof coating.

Flat roofs with a slope angle of up to 2-3 degrees usually require laying at least four layers of roofing material: three layers of the RPP-350 brand, the fourth - of the RKM-350 brand. If the roof is used for the movement of people, there should be four underlying layers - such a roof can withstand both the weight of a person and any snow load.

Roofs with a slope angle of 3 to 6 degrees are usually covered with three layers of roofing material - two underlying and one roofing. If the slope of the roof is from 6 to 15 degrees, two layers of roofing material are sufficient. On roofs with an angle of inclination of more than 15 degrees, roofing material is rarely used, usually as a waterproofing layer for other types of coating: corrugated board, ondulin or slate.

When calculating the material, it is necessary to take into account not only the number of layers, but also a mandatory overlap of 10 cm for each strip, as well as a margin of 20 cm for the length of the strips at the ridge and at the roof slope. The resulting amount of material is rounded up to the area of ​​the roll.

Mastics for gluing roofing material

To ensure a tight fit of the roofing material to the roof, it is glued to bituminous mastic. The exception is the built-up roofing material, which already has an adhesive layer. Bituminous mastic can be either cold, ready-made, or hot, which must be preheated at a temperature of 150-200 degrees.

Cold solvent-based mastic is usually sold in jars, it is enough to stir it thoroughly before use. Cold mastic is much easier to apply, but it takes longer to dry, and besides, it does not provide sufficient coating strength. Therefore, when covering the roof with roofing material, hot mastic is more often used.

Making hot mastic takes some time. Bitumen is sold in lumps in solid form, and it must be heated to a viscous state, after which a reinforcing filler is added to it. Bitumen is heated in a boiler, bucket, barrel or any other container using blowtorch or open flame until foam and rare bubbles form. The foam is removed, and a filler is added to the bitumen in an amount of 20% by volume. The filler can be sawdust, peat, sand, fiberglass. The mastic is thoroughly mixed and applied hot to the roof surface.

Roofing material laying technology

Embedded roofing material laying technology

A properly laid roofing material has guarantee period service 5 years, but good care and timely cleaning of the roof from snow and debris, repair of damaged areas, such a roof can last more than 25 years. A do-it-yourself roofing felt roof will help save a lot of money on the construction of a garage and other buildings.

About 40–50 years ago, roofing material was considered one of the main roofing materials; it was used not only on outbuildings, but also residential buildings. Today appeared a large number of modern roofing materials with high performance characteristics. But for the manufacture of roofing material, new materials and technologies are used, which made it possible to significantly improve all its indicators. Now it has become much stronger and more durable, the service life has been significantly increased, with the observance of the production technology and the use of a high-quality coating, the tightness is maintained for 25 years or more.

The main disadvantage of roofing material is low design parameters. In this regard, at present, such coatings are made only on outbuildings and garages.

The presence of many types of rolled coatings has led to the fact that roofing material is called all materials, which use modified or ordinary bitumen as a hydroprotection. This is made on the basis of building cardboard or non-woven synthetic materials coated with bitumen. For additional protection from the harmful effects of hard ultraviolet rays, a crumb of natural or artificial stone. The reverse side has a plastic film or stone chips, which does not allow the coils to stick together.

What types of roofing materials are often called roofing material?

Before starting work on fixing the roofing material, you need to carefully study the markings. What is indicated on the packaging?

Prices for roofing material

Ruberoid

Letter designations

On the packaging, the manufacturer indicates the letters "K", "P", "E", giving General characteristics material. According to the indicated order of letters, roofing material can be roofing, lining and elastic. The letter "P" means that it is the roofing material in the roll.

In addition to these inscriptions, a characteristic of the protective dressing is given - fine-grained "M", pulverized "P", coarse-grained "K", scaly "Ch", colored "C".

Coarse-grained most often made from natural granite, can withstand significant mechanical stress.

Fine-grained is a bit like ordinary sandpaper; fine fractions of purified river sand are used for preparation. Marine is not suitable, it does not have sufficient hardness indicators. Scaly is made from slate, shaped like scales small fish. Pulverized is used for materials used as a bedding layer for finishing roofing. It is made from talc or chalk.

Numerical designations

The package should indicate the weight of the roll and the number of square meters, the standard width is 100 cm. The thickness of the roofing material depends on its specific purpose, for the finishing coating of wooden roofs, the thickness should be within 3–4 mm. Thinner types are allowed to be used only as lining additional waterproofing layers.

How is roofing material fixed on a wooden roof

The fixing methods are chosen by the developer, taking into account their desires and the characteristics of the roof. You need to decide on them even before buying a roofing material, there are types that are suitable only for hot or cold fastening.

Important. For roofing material you only need to cook solid crate. The smoother it is, the more reliable the coating.

The crate can be made from edged or unedged boards, OSB or plywood. The gaps between the boards should not exceed 2-3 cm, the nail heads should be recessed, this is a prerequisite. The fact is that ordinary nails can stretch a little in the process of changing the thickness of the boards or other fluctuations. truss system. As soon as the hats appear above the surface of the boards, the roofing material will break through, you will have to immediately fix the leaks.

How can roofing material be fixed to a wooden roof?

1. Using mastic or glue.

Reliable, fast and simple method. The only condition is that the wooden base must be dry, otherwise the degree of adhesion is insufficient. Now in the implementation there is a huge selection of different brands of mastics, but apart from the name and cost, there is no difference between them. All of them are made using ordinary cheap bitumen. There is no need to use a modified one, the mastic is covered with several layers of roofing material and is reliably protected from ultraviolet rays. But such cheap mastic can be bought only if there are no elements on the roof that should be sealed without further coating with roofing material.

Mastic can be used cold or it must be preheated. Experienced roofers do not advise using compounds that require heating. It's long and difficult. In addition, it is almost impossible for beginners to withstand the recommended temperatures. As a result, there are areas with cooled mastic, the roofing material will not be fixed to them securely. But there may be overheating of the material, if too high temperatures it also loses its original properties. And the last problem is that it is necessary to heat it with an open fire, and it is dangerous to do this on the roof - there are big risks of getting burned, an overheated composition can ignite spontaneously with all very negative consequences.

AT recent times a special glue for roofing material appeared, but it is rarely used for wooden roofs - it takes too much time to apply the composition to the surface of the wooden crate.

2. Welding.

For this method, you need to buy a special roofing material, the surface is heated by a burner. It is necessary to work very carefully, wood is a combustible material. During heating, a special protective film melts, bituminous mastic becomes liquid.

Important. The quality of fastening the roofing material to the roof depends only on the experience of the master. If you are encountering such work for the first time, then it is highly recommended to practice. It is necessary to find out approximately the time of heating the roofing material, the speed of unwinding the roll, the force of pressing the heated material to the crate.

It is possible to stick roofing material only on a continuous crate. If there are cracks on it, then the hot soft roofing material will fall into them, the surface will become uneven, water will constantly accumulate in the recesses. In addition, the sharp corners of the wooden crate reduce the thickness of the roofing material; leaks often appear in these places.

3. Special self-adhesive roofing material.

The most modern and most expensive roofing material. It is made from modified bitumen with increased adhesion. During fastening, the protective polyethylene film is gradually removed, the roofing material is tightly pressed against the surface of the crate with a special rubber roller. Such material can only be used on a perfectly flat surface.

4. Using nails or wooden planks.

The traditional method, proven by many decades of use. Studs should have wide caps made of galvanized sheet steel. If they are not there, then you can cut galvanized steel squares yourself, but appearance roofs deteriorate significantly.

Fastening with wooden slats is more reliable, the fixation of two strips is done along the entire length. It is advisable to impregnate wooden slats with an antiseptic before use; during processing, the manufacturer's recommendations should be strictly followed. Due to the fact that the overlap is not hermetic, up to 15 ° increases minimum angle slope slopes and up to 20 cm overlap width.

Step-by-step instructions for attaching roofing felt

Consider an example of fusing roofing material on a shed sloping roof. A solid crate is made of edged boards 20 mm thick, metal drips are nailed along the perimeter of the roof.

Step 1. Take the rolls of roofing material to the roof, prepare the tools. You will need a tape measure, a mounting knife with a set of interchangeable blades, a metal square.

Step 2 Roll out the roll on the free surface of the slope, measure the length of the roofing material. It should be 10-15 cm longer than the width of the slope. Under the metal square, cut a piece of the required length.

Practical advice. The material should be cut from the reverse side, the crumb greatly complicates the process. Hold the knife blade at an angle of about 30 °, the smaller it is, the easier it is to cut. Press the knife with great force, it should be constant along the entire length of the material.

Step 3 Prepare all the segments in this way, roll the finished pieces into rolls. If the roof slope is even, then the rest can be cut off in one pattern. If there are gaps, then it is much easier to slightly increase the margin in length, and after fastening, cut off the excess. Measure each individual piece for a long time.

Step 4 Lay the first strip of roofing material in place, check its position. Make sure it lies as flat as possible.

Step 5 Light the burner, adjust the flame strength. Stand on the roof, bend a piece about 40–50 cm long from the edge of the roof.

Step 6 Gently heat the bitumen with a burner, the protective film should melt, the roofing material will soften. Before it cools down, quickly wrap the heated piece over your area and press it all over. This must be done in a timely manner, after pressing along the edges, bitumen should come out. This indicates that the heating temperature is selected correctly. We have already mentioned that it is advisable to practice on the segments, but only after gaining practical experience to engage in work on the roof.

Step 7 Wait a few minutes, let the freshly glued area cool down a bit. Wind the remaining piece of roofing felt into a roll.

Step 8 Go to the vacated area on the roof and start heating the roll. Keep the burner flame at medium speed, never keep it in one place. Immediately warm up only the easily accessible surface of the roll. As soon as the temperature reaches the desired values, roll out the roll and press the hot part to the base of the roof.

Step 9 Stand on the already glued area and continue to work. The roll needs to be heated and rolled out without stopping, press the roofing material against the crate with your feet.

According to the same algorithm, all remaining pieces of roofing material are glued. Do not forget to overlap, in places of overlap, pay special attention to the quality of heating of the material. A small amount of bitumen should protrude along the entire length of the overlap, there should be no breaks. For a guarantee, you can reheat the seams.

The final stage of work - heating the seams

Fastening roofing material with wooden planks

Prices for different types of building boards

Building boards

This option does not require a burner, which simplifies the process, not every master has it. Yes, and working with a burner requires practical experience, inept actions can burn through holes in the material.

The roofing felt will be fixed with antiseptic impregnated wooden slats 2×3 cm, ordinary carnations 4–5 cm long. Roof covering in two layers, the first along the slope, and the second across, with an overlap of 25–30 cm. It will take about three hours for a roof of 35 m2, from they take one hour to prepare and impregnate the rails with an antiseptic.

Step 1. Nail unedged boards to the rafters, try to place them as tightly as possible. This will be a continuous crate for roofing material. Fix the wind boards along the perimeter of the roof.

Step 2 Bring the rolls onto the roof, roll them along the slope. As practice shows, unscrupulous domestic coating manufacturers are often found, about a meter of material may be missing in a roll. You need to keep this in mind when calculating the quantity. Fix the roofing material along the edges with a construction stapler. Leave a bend of a larger length, then all ends will be neatly cut to fit the ruler. Before nailing with a stapler, carefully align the material, do not leave wrinkles. You don’t need to drive in a lot of staples, you shouldn’t make extra holes. Use staples only along the edges, in the future these places overlap top sheets. According to this algorithm, lay the first layer of roofing material, do not forget to constantly overlap.

Laying the next canvases and fixing their edges

Step 3 Start laying the second soybean cover, now do it across the slope, the overlap is the same as in the first case.

Laying the second layer perpendicular to the first and fastening with a lath

Step 4 Nail wooden slats in places of overlap. The distance between the nails is 25-30 cm, press the slats tightly. If the crate has irregularities, then reduce the distance between the nails, they should bend the rail and press it over the entire surface of the slope. To increase the reliability of fixing the rails, you can use self-tapping screws instead of nails, but this slightly increases the roofing time.

This completes the roof covering, if you wish, you can mount the drainage system. But on ordinary outbuildings, a drain is rarely made.

It is better to work with the material in warm, dry weather, do not pay attention to the assurances of manufacturers who allow laying at low temperatures. None of them has yet managed to outwit the fundamental laws of physics. And they say that all bodies become harder with decreasing temperature, this automatically lowers the adhesion coefficient. Low temperatures create another problem. When in contact with a cold crate, the bitumen cools quickly and does not have time to deeply soak into the boards. As a result, the fixation strength is significantly reduced.

The substrate to be coated must be dry and clean. There are always a lot of small chips on the surface of the boards, it should be thoroughly cleaned. You can use an ordinary broom or vacuum cleaner. Carefully inspect the surface, if after warping the sharp edges of the boards protrude above the plane, then they should be planed. Can be used manually or electric planer. There are no such tools - level the boards with a sharp ax or a wood chisel.

To facilitate work on steep slopes, make a special ladder. In the upper part, it is fixed on the ridge, and the elongated steps will allow you to reach the edge of the rolled roofing material. By the way, on such roofs it is possible to lay roofing material only along the slope, the risks of water leakage are minimal. Laying along the roof is much faster, safer and easier than across it.

Always follow the safety rules, do not work without a safety cable.

It is advisable to purchase a special carpenter's belt, with its help all the tools will be at hand.

The greater the angle of inclination of the slopes, the greater the distance can be between the boards of the crate. But you should not abuse this, experienced roofers advise, if possible, to always make a continuous crate. In places of sagging, the roofing material, if it does not break through, will stretch out over time. And this also creates the risk of leaks.

You can find tips for painting roofing material. No need to waste time and money. There will be no positive changes, on the contrary, the paint will fall off in pieces over time, the roof will look like a dirty field.
