From building materials, roll roofing is a practical roofing covering. Not distinguished by its decorative appearance, it is widely used to cover the roofs of non-residential and commercial buildings.
But low price, simple installation, good insulating qualities have influenced the fact that rolled roofing materials have become in demand in private construction. Nowadays, soft roll roofing is manufactured using new modern materials that have improved its qualities, increased strength, and durability. Today, rolled materials for roofing can be confidently used as an alternative to slate, ceramics and even metal coatings. Our construction magazine will tell you about prices, construction, and modern types of roll roofing.
Soft roll roofing is roofing materials, the constituent layers of which are pressed into the form of a long sheet, which is rolled into rolls when finished. Rolled roof coverings, thanks to this shape, are very convenient and practical to transport, store, and lay on the roof slope. Such advantages have ensured their demand in the industrial and civil construction sectors. Soft roll roofing has the following device:
Attention! Different types of soft roofing for roofs differ in their composition, design and cost. The most inexpensive and well-known are roofing felt and roofing felt, they have a low cost and are quite practical. The price of modern membrane roll materials for roofing is much higher, but stronger materials, improved installation technology, durability and other characteristics will justify your costs.
Advantages of soft roll roofing
The soft roof structure consists of tightly adjacent layers that form a sealed, durable coating, the significant advantage of which is the almost complete absence of seams. The big advantage of this coating is that it can be used for roofs with an inclination angle of 1 degree or more. The main advantages of a soft roof are:
1. High resistance to moisture. Soft roofing is made using a base of cardboard or fiberglass impregnated with bitumen-polymer impregnation. It is not susceptible to moisture and has antiseptic properties.
2. Affordable price. The cost of rolled roof coverings is an order of magnitude lower than metal tiles, ondulin and others. It is very practical to use for coating non-residential premises or industrial buildings.
3. Resistance to high and low temperatures. Soft coatings perfectly withstand temperature changes, do not deform and do not lose their qualities. Used in regions with different climatic conditions..
4. Light weight. Roll roofing, the layers of which are stacked on top of each other, weighs less than many other roofing materials, and therefore places almost no load on the rafters and roof frame.
5. Easy to lay and install. The technology for laying bitumen and polymer materials is quite simple and allows installation with my own hands without resorting to the help of specialists.
6. Sound insulation. A bitumen roof absorbs well external noise caused by wind or rain.
Low price and weather resistance are not the main advantages of rolled bitumen roofing coatings. The most useful quality– this is flexibility and the ability to lay material on the roof surface of complex shapes.
Types of rolled soft roofing
Previously, roll roofing materials were only roofing felt and roofing felt, but today new ones have appeared with higher characteristics and qualities. Let's look at everything in order.
Despite the wide variety of roofing materials, both modern and traditionally used, soft roofing stably holds its position, which even the latest fashion trends cannot shake. The reasons for its popularity lie in the advantages that no other roofing material has, namely the ability to be laid in any direction. Of course, in order for the roof to have the proper qualities, you should choose “soft roofing” roofing materials in accordance with their purpose.
Scope of application of rolled roofing materials
The choice of roofing material should be made based on your requirements for results, i.e. will have to analyze performance characteristics materials, protective and technical, correlate them with appearance. Although the attractiveness of the roof is quite important for general design structures, but first of all it is recommended to study the technical properties.
Let's start with the fact that roll roofing is used for roofs with a slope of 10 to 30 degrees. Soft roofing can be used for gable and single-pitch roofs.
Typical applications for soft roofing:
- roofs of complex construction during large-scale construction,
- flat roof covering,
- creating roofs over industrial facilities and civil structures.
In principle, roll roofing can be used during construction country house and a presentable cottage, it will be able to provide the required level of attractiveness and protect a structure for any purpose from rain or snow.
On a positive note, it should be noted that if a leak is detected, there is no need to completely change the entire coating - it will be enough to find the leaky area and cover it with a weld-on patch.
The high demand for weldable materials today is ensured by their abundance aesthetically pleasing and a service life measured by a quarter of a century.
Roll roofing materials and their varieties
All soft roll materials are conventionally divided into several types, each of them is characterized by certain technical features concerning their structure, installation method and subsequent operation.
The category of roll materials includes materials whose installation process involves the use of bitumen or polymer mastics, used both hot and cold.
Modern rolled materials can also have an adhesive layer, which makes the installation process as simple as possible: it will be enough to remove the protective film and connect the strips of material, the joints will be quite strong.
Fused polymer roofing materials require the use of auxiliary equipment: a gas cylinder with a burner.
The classification of soft roofs is made in accordance with GOST 30547-97, which contains information about the parameters of this type of coating.
What types of roll coverings are used in today's construction?
Depending on the structure of the base, we can distinguish types that have a base and those created without it.
The types made on the base are in turn divided according to the type of base, which can be used as:
- cardboard or asbestos,
- polymer material or fiberglass.
Depending on the coating composition, there are:
- bitumen roofing materials,
- bitumen-polymer,
- polymer.
If you take into account the protective layer used, you can distinguish materials with sprinkles, film or foil.
Fused roofing, judging by the material of manufacture and the structure of the sheet, is a bitumen-polymer material on a synthetic base, which can be fiberglass, fiberglass or polyester.
On both sides, the reinforcing layer is covered with layers of bitumen-polymer material, in turn they are protected with low-melting polyethylene film, the front layer is covered with stone filling.
Modern materials have significant differences with their predecessors, roofing felt and rubemast, however, the production of cardboard-based materials does not stop and they are in stable demand.
To understand the quality of materials in more detail, it is advisable to study their production technology:
Roll roofing and its advantages
Roll roofing has a number of significant advantages:
- the low weight of the rolls allows for easy transportation,
- installation is carried out quickly, does not require special skill and skills to perform the work,
- the resulting surface is durable and elastic, provides sound insulation of the roof and reliably protects the house from precipitation,
- it is environmentally friendly
- retains heat well
- retains original properties after exposure sun rays and temperature changes.
If in the old days bituminous roofing materials, for example roofing felt, were made on a cardboard basis and especially long term services did not differ, today fiberglass, a material not subject to rotting, is usually used as a base.
A more problematic aspect was the tendency for the bitumen roofing material, which is used as a base covering, to age. The issue was resolved by introducing polymer modifiers into the bitumen coating, which, by the way, are also classified as environmentally friendly substances.
Sufficiently high performance characteristics contribute to the fact that rolled roofing materials, the price of which, by the way, is quite affordable, are widely used in the construction of residential buildings and technical structures.
The cheapest roofing material, and therefore affordable for any budget, is roofing felt; it is made on a cardboard base impregnated with bitumen. A composition of bitumen with mineral fillers is used as a base coating; the front side of the material is coated with fine mineral powder. Ruberioid made according to modern technologies, about 10 years.
The difference between rubemast and roofing material is the presence of a bitumen binder layer on the underside of the web.
Similar materials on a higher quality fiberglass base:
- glass master,
- glass roofing material,
- glass insulation
More modern version rolled roofing materials with fairly high performance characteristics - this is the so-called euroroofing material, which is a polymer-bitumen roofing membrane.
The most wear-resistant and easiest to install is membrane coating; it can be called the youngest in this line of materials.
Self-adhesive coatings are easy to install; before laying the next strip, it is enough to remove the protective layer from the back surface of the material, then lay it on the roof surface and roll it out. A sufficient condition for the successful completion of the joining process is high temperature environment, i.e. It is advisable to perform the work in the summer, on a sunny day. The limiting factor in the use of coatings of this type is the rather high cost of the material.
Let's watch a video about modern roofing materials:
Baseless roofing materials and their features
Among the advantages of baseless materials, they note the absence of a rigid base; at first glance, an insignificant fact, in fact, allows the installation of the material on surfaces with large deformations, which sometimes turns out to be very important. Technologies for the production of baseless materials allow us to claim that they are environmentally friendly.
Izol
To produce Izola, scrap rubber is used, having previously been subjected to devulcanization in a bitumen environment. Further, its composition is enriched with fibrous filling fragments; asbestos fibers and other additives can be used for their production.
The material obtained in this way is elastic and resistant to biological influences. Deforming loads do not lead to a violation of the integrity of its structure, even if the processes occur during low temperatures. The water-repellent characteristics of the material are high, temperature changes do not have a negative effect on them, the scope of application of Izola is the construction of a waterproofing layer.
Brizol
The second popular baseless roll coating is Brizol. It is made from shredded tires; plasticizers, fillers and petroleum bitumen with varying degrees of viscosity are also used in production.
Modern manufacturing technologies make it possible to obtain a coating that is characterized by excellent resistance to aggressive environments; even 20% hydrochloric or 40% sulfuric acid cannot cause destruction of the material, high temperatures will not have a significant impact on its structure, brizol can withstand heating to temperatures above 60 degrees.
As a positive point, it should be noted the ability to retain not only moisture, but also a gaseous environment.
Brizol goes on sale in the form of a rolled material; its inner surface is treated with fine powder before packaging to prevent sticking.
GMP
The material is made based on polyisobutylene. The material has high quality characteristics and has a long service life. There are three brands of material on sale, its area of application is shelter flat roofs and arrangement of hydro- and vapor barrier systems during the construction of roofs.
Film materials are also produced using baseless technologies; the manufacturing materials are polyamide and polyethylene. Attractive features These products are lightweight and completely waterproof. In addition, the materials are resistant to temperature changes. However, coatings have significant shortcomings: they are quickly destroyed when exposed to direct rays of the sun, so the scope of application is limited; installation is not carried out on open surfaces.

In the video you can see how a soft roof is laid:
What are the advantages of roll roofing?
On the market of modern roofing materials, soft roofing rolls are the most affordable in price, but nevertheless have high quality characteristics.
The next indisputable advantage is small specific gravity materials, the ability to use them for the construction of new and repair of old roofs that do not differ in the strength of the rafter system.
Installation and transportation costs are not high, it is possible to carry out loading work without the use of special equipment.
An attractive point for consumers is the lack of need for constant maintenance throughout the entire operational period. Considering the good performance of noise insulation and waterproofing, the materials, according to consumers, can be classified as ideal.
Roofing roll material is the most popular way to finish the roof of any country house. Modern market offers a wide selection of materials, each of which is good in its own way. What to give preference to and what to pay attention to when choosing?
Main categories
All rolled roofing materials are divided depending on the type of base into basic or baseless. According to the type of components of the coating composition, they are bitumen, polymer or bitumen-polymer. The base can be cardboard, asbestos, polymers, fiberglass or a combination of materials, and the protective layer has a fine-grained, coarse-grained or fiberglass structure. All these types of rolled roofing materials are widely used in construction. Let's look at the features of each type in more detail.
Bitumen: cheap and easy
Glassine is another material created from roofing cardboard and impregnated with bitumen. The material is thin and less durable compared to roofing felt, so it is most often used as a lining.
Welded roofing materials
Fused roofing is perfect solution for the arrangement of roofs of buildings and structures in the field of industrial and civil construction. Such materials are suitable for waterproofing both roofs and foundations, floors and ceilings. Rolled roofing material is easy to install, so you can complete a large amount of work in just a day. Its peculiarity is that rot-resistant fiberglass or fiberglass fabrics are used as a base, which increase strength.
Polymers are used as bitumen modifiers, which increase resistance to various influences and increase strength. Rolled roofing material is characterized by high elasticity, flexibility at low temperatures and high heat resistance. An important role in the materials being deposited is played by the structure of the top layer, the task of which is to protect the roof. The roof covering should serve as protection against heat, ultraviolet radiation, precipitation. To minimize this impact, coating with sprinkles is used.
Rolled roofing waterproofing material most often has a coating of different fractions - coarse-grained or fine-grained, scaly or dusty. Basalt, shale, sand, and ceramic chips are used as raw materials. When choosing, you should focus on several factors:
- The complexity of the topography of the roof structure, as well as the angle of its slope.
- Temperature conditions in the region.
- The amount of precipitation that falls on average per year.
- Possible loads that can lead to deformation.
Bituminous materials for waterproofing
A number of roofing materials serve not only to cover the structure, but also to provide high-quality waterproofing. Among them is metalloizol. This material has a three-layer structure: bitumen - foil - bitumen. This is a durable roofing covering that shows excellent performance properties, is highly durable and reliable.
No less popular is bitumen roll roofing and waterproofing material called isol. During production, rubber, mineral sealants, antiseptics and polymer additives are added to it. This composition ensures that the material will exhibit increased heat resistance. Suitable for flat shapes and slabs. A waterproofing agent is created on the basis of asbestos cellulose, the main difference of which is increased rot resistance. It is widely used in waterproofing basements and areas that are poorly ventilated.
Thus, roofing bitumen rolls and built-up materials are a wide selection of coatings that are made in the form of sheets and can be used in different areas construction. The secret of their popularity is their affordable cost, as well as increased resistance to various influences.
Bitumen-polymer materials
If the bottom layer in the form of a binder component is glued to the fused roofing, it will show good waterproofing properties. Rolled roofing waterproofing material most often has a binder component in the form of roofing bitumen and fillers in the form of polymer additives, which increase the service life and performance properties.
Leads to increased heat resistance and decreased frost resistance of the coating. To avoid such phenomena, atactic polypropylene (APP) or styrene-butadiene-styrene elastomers (SBS) are added. In this way, rolled polymer-bitumen roofing material is obtained. It is more expensive, but its excellent performance properties combined with high reliability and durability will appeal to many owners of country houses.
Features of bitumen-polymer roofing materials
Two-component roofing materials in the form of rolls have recently been in high demand. They consist of bitumen and polymer, the volume of which is about twelve percent. The basis for this type of coating is polyester, fiberglass, crumb rubber or thermoplastic. This roofing roll material has a number of features:
- High plasticity.
- Resistant to cracking.
- Possibility of operation in different temperature ranges.
- High strength.
- Reduced brittleness temperature.
- Increased softening temperature.
The use of bitumen-polymer types of coating is advisable when constructing a flat or pitched roof with a maximum slope of twenty-five degrees. Otherwise, the coating may slide off. Roll roofing materials for the top layer based on bitumen and polymers are presented in several types.
"Monoflex"
This is a multilayer material consisting of polyester, film, polymerized bitumen as a base and a coating in the form of ceramic chips. Thanks to modified additives, performance characteristics can be improved. This material has a number of varieties, the most popular of which are Copprflex coatings with an outer layer of inert copper and Aluflex with an outer layer of aluminum. These coatings are characterized by high heat resistance and durability.
"Isoplast"
Rolled roofing material "Isoplast" consists of polymerized bitumen and a base in the form of polyester or fiberglass. It is available in two varieties - roofing and lining. The top layer has a coarse-grained topping on the front side and a plastic film on the other, and the bottom layer is a polyethylene film, which is covered on both sides with a fine-grained fraction. This arrangement of the material makes it flexible, resistant to bending and cracking. The polymer film on the bottom serves to protect the coating and guarantee its safety.
Other bitumen-polymer materials
Any roofing roll material based on bitumen and polymers has a number of advantages:
- The high quality of the binder component is the key to reliability under any temperature changes.
- High elasticity results in improved flexibility at low temperatures.
- The coating has good adhesion to the topping.
Among the materials popular in construction are the roll roofing coverings of the Technoelast series. They are produced by applying a bitumen-polymer binder on a polyester or fiberglass base on both sides. It, in turn, consists of bitumen, an SBS modifier and a mineral filler in the form of talc or dolomite. And the protective layer is created on the basis of sprinkling of different fractions and polymer film. The coating is widely used in creating roofing carpets in various buildings that are operated in any climatic conditions.
Polymer roll roofing materials
Rolled polymer roofing material is created on the basis of petroleum-polymer resins or rubber. These types of coatings belong to a new generation and are durable and highly reliable. Their service life reaches twenty years or more, and they can cover roofs of any configuration - flat, pitched, flat and even with round slopes. Laying is carried out by strip or continuous gluing based on adhesive mastic, and the preparation of the base plays an important role. Some materials are secured by weights or mechanically.
Polymer membrane
This is a modern roofing roll material, which is increasingly used in roof repair and finishing. Its popularity is due not only to its high reliability, but also to a wide range of color options, resistance to temperature changes and durability, which reaches forty years. This innovative material is a single-layer roofing, which is made from elastic polyvinyl chloride by hot air welding. This roofing covering is different:
- resistance to ultraviolet radiation;
- immunity to the most unfavorable weather conditions;
- resistance to various bacteria and chemically aggressive substances;
- resistance to rotting and decomposition;
- the ability to create a coating with a breathable effect.
All this distinguishes this material roll roofing (GOST is installed in technical documentation) from others.
Types of polymer membranes
PVC-based membranes are the most common in Russia. They consist of polyvinyl chloride to which plasticizers are added. Their purpose is to increase frost resistance and provide elasticity. A special reinforcing base imparts reliability and strength, while the seam sections are strong and airtight.
Membranes based on thermoplastic polyolefins are an innovative material to which components are added that improve the fire resistance and performance properties of the surface. Such membranes are characterized by a combination advantages of PVC and rubber. Therefore, they are better combined with bitumen. And this, in turn, affects the greater strength of the material.
Membranes based on EPDM have high elasticity and the ability to operate for a long time in the most extreme conditions. They are produced reinforced and unreinforced, which is necessary to increase the strength and reliability of the material. Moreover, any variety is characterized by elasticity and strength. The kit consists of additional parts that can be used to waterproof difficult areas - sealants, fasteners.
Roofing materials by class
Depending on their durability, all roofing bitumen materials are divided into several types:
- premium (service life - 25-30 years);
- business (service life - 15-25 years);
- standard (service life - 10-15 years);
- economy (service life - 10 years);
- sub-economy (service life no more than five years)
Premium materials include the Technoelast series. The peculiarity of these coatings is the possibility of creating a breathable roof, from which moisture will be removed, which has the ability to reduce the durability of the roof. Using materials of this type, you can build a single-layer roofing covering, solving the problem with swelling and making the installation itself easier and more convenient. To arrange the bottom layer of the roofing covering, you can use Technoelast Fix, which makes it possible to install the roofing carpet on the base. The roof will be resistant to deformation and able to withstand heavy loads. The operational features of the coating are such that it can be used in regions with any climatic conditions.
Among the business class materials, two can be distinguished - “Uniflex” and “Ecoflex”. The first one is good because it serves effective protection from moisture penetration, contributing to the durability of the structure. Both materials are waterproofing sheets that provide roof ventilation. "Ecoflex" is an excellent solution for underground structures. It is advisable to use this roofing roll material in regions with high temperature conditions. Thanks to its quality and reliability, it will serve as roof protection for quite a long time.
Among standard class materials, Bipol is in demand. It has a durable, rot-resistant base, which is coated on both sides with high-grade bitumen-polymer binder. Based on this material, it is possible to construct roofs with a low slope and waterproof the foundations of buildings and structures.
Economical types include “Linokrom K”, with which the top layer of the roofing carpet is installed. It can be used as a vapor barrier material in the lower layer of the system. Its protective layer is made of fine-grained powder or polymer film.
"Bikrost" is a popular material, which is a waterproofing sheet with a durable base based on bitumen binder. It is used when installing the bottom layer of roofing carpet. The protective layer is provided by a fine-grained coating or film. The cheapest rolled roofing material is glassine. It is a roofing cardboard that is additionally impregnated with petroleum bitumen. Based on this material, roofs can be repaired and equipped with a service life of a maximum of five years.
conclusions
As you can see, modern manufacturers offer a wide selection of roofing roll materials. Each of them has its own technical and operational features, each is designed for a specific roof structure. That is why it is so important to consider the composition, application features and climatic conditions own region. All this together will allow you to select the most suitable building material for specific conditions.
Rolled materials for roofing are presented on the modern construction market so widely that even a professional needs time to choose the most suitable one. suitable type coverings. Bitumen, polymer and tar, basic and non-basic, built-up and not built-up, with and without a protective layer - a variety worthy of modern times.
The first bitumen roll materials were produced in Russia in 1877 at a plant in Syzran under the leadership of engineer A. A. Petrov, who used the developments of D. I. Mendeleev. Since then, production has developed and the range has increased. Affordable, easy to use and possessing the necessary physical and mechanical properties for reliable waterproofing, they became widespread in industrial construction, and then in mass housing construction. During the heyday of stagnation in the Soviet Union, more than 1 billion square meters were produced annually. meters of roofing felt, glassine and roofing felt.
Nowadays
The simplest, inexpensive and most common rolled roofing material that has survived to this day from those times is roofing felt. Roofing felt fell out of use due to the carcinogenicity of its binder (tar). Glassine is still used today.
Glassine is a roll of roofing cardboard impregnated with soft petroleum bitumen. Used as a vapor barrier, backing layer in multi-layer roof coverings, for equipment packaging. Ruberoid is roofing cardboard, first impregnated with soft low-oxidized bitumen, then on both sides with highly oxidized refractory bitumen, on top of which a protective coating is applied. The sprinkles can be large and flaky. A fine-grained coating or protective film is applied to the reverse side. Ruberoid is marked with a group of alphabetic symbols and numbers. The first letter P is roofing felt, the second letter characterizes the type of use (K - roofing or P - lining, the third letter indicates the type of coating (K - coarse-grained, P - dusty or fine-grained). The numbers indicate the brand of roofing cardboard (300, 350, 400). The difference between brands is the tensile strength and density of the coating. The higher the brand, the stronger material. Due to its low cost and decent physical and mechanical properties, roofing felt is still popular. 
A roof covered with roofing felt should be made of 4 layers with a slope of up to 1.5%, and of 3 layers with a roof slope of more than 1.5%, gluing first the lining layers onto the bitumen mastic, then the covering layer with sprinkling. At the junctions and at the funnels, 2 additional layers should be glued, and in the valleys, 1 additional layer. Ruberoid is used on flat and low-slope roofs (up to 15%). The standard service life of a roofing felt roofing material when installed correctly is up to 12 years. In practice, however, the service life of roofing felt is significantly lower, mainly as a result of improper installation of the roofing covering. The disadvantages of roofing felt include its low biological resistance, low mechanical properties of the cardboard base and high labor costs for gluing roofing felt to the base. Even with all these shortcomings, ordinary roofing felt is still worthy of use in roof repairs. Ruberoid is used to a limited extent as a new covering for flat roofs of small areas, for example, a garage, or as a budget and temporary option for pitched roofs. In this case, mechanical fastening of roofing material to a solid base is provided through a thin wooden plank or steel packing tape. Time forward
In order to speed up the process of gluing sheets and minimize errors when installing roofing carpets, it was invented to make a fusible layer on the reverse side of the roofing material bitumen mastic, which, when heated with a propane torch, softened and glued the canvas to the base. This is how the second generation of bitumen products arose - a type of weld-on materials (Rubemast). For the installation of new soft roofs on buildings of normal responsibility class, roofing felt, even fused roofing material, is not currently used. The third generation of soft roofing materials appeared when, to increase rot resistance and strength, the cardboard base was replaced with a glass base. To this day, glass-based fused materials are widely used on objects for various purposes..
In accordance with the classification of roofing materials based on price, the third generation consists of both economy-class and standard-class materials. The economy class group includes the following items: Stekloizol, Steklobit, Filigiz, Bireplast, Steklomast and other types of glass base impregnated with oxidized bitumen. The standard class is represented by such types of materials as Linocrom, Bipol, Bicrotol, Bicroelast, KTkrom. These rolls are made from both glass material and non-woven polyester, and a small amount of polymer additives can be added to the bitumen binder. Fusing of rolls is carried out using gas burners, infrared emitters, and construction hair dryers. If open fire and other heating methods are prohibited at the work site, the installation of the carpet is carried out by thinning the film on the lower welded side with solvents such as white spirit. Third generation roofing materials are actively used in new construction thanks to economic efficiency, high speed of work and extended service life. A properly executed coating will last 10-15 years.
Era of polymer bitumen
The use of durable, rot-resistant and elastic bases does not save roofs from leaks due to cracking and gradual destruction of layers of oxidized bitumen under the influence of tensile forces, temperature changes and ultraviolet radiation. As a result of changing the conditions for modifying bitumen from conventional oxidation with air to the introduction of polymer additives into the bitumen mixture, the fourth generation of rolled roofing materials appeared: bitumen-polymer materials.
Modification of bitumen is carried out by introducing 2-6% by weight of polymer compounds into bitumen: APP modifier (atactic polypropylene), after modification, obtaining plastobitumen, or SBS modifier (styrene-butadiene-styrene), obtaining rubber bitumen after mixing. Polymer additives significantly improve the elasticity of bitumen and increase its heat resistance and frost resistance. At the same time, APP-modified bitumen is more resistant to ultraviolet radiation and temperature increases, and SBS-bitumen is more frost-resistant than APP-bitumen. 
The technological process of modifying bitumen with polymers has a higher cost than the process of bitumen oxidation, and if we take into account the cost of polyester bases and other raw materials, as well as the cost of the latest equipment for the production of bitumen-polymer materials, the price of the final product seems to be very high. However, in most cases the price is justified: if the requirements are met correct selection elements of the roofing carpet and following the fusing technology already well known to roofers, a roof made of modern bitumen-polymer materials can last 20 years or more. Among the advantages of bitumen-polymer materials is high mechanical strength, elasticity, ability to self-heal in places of small punctures and cuts.It is difficult to list absolutely all brands of bitumen-polymer roll materials, but the most common of them are modern materials TechnoNIKOL group (Technoelast, Technoelast-decor, Technoelast-FLAME-STOP, Uniflex, Ecoflex and others), Filikrovlya LLC (Filizol, Filikrov), Safety line (Safety) from the Tegola company, materials IKOPAL (icopal®), SYNTAN (SYNTaN) , ULTRANap®, Villatex and many others.
Bitumen-polymer coatings are fused onto a solid rigid base in 2 layers, in some cases, 1 layer is allowed. An additional layer is applied at junctions and valleys. Baseless rolls
Separate group of roll roofing coverings These are baseless materials. The most familiar of them is polyethylene film, which is made from high-density polyethylene by extrusion. Polyethylene film with a thickness of 0.06 to 0.2 mm, reinforced or ordinary, used for lining layers on both flat and pitched roofs. Other baseless roofing materials are Izol, Brizol, GMP (polyisobutylene). Izol and Brizol are rubber-bitumen materials by type of binder. GMP – polymer-bitumen material. This group of roofing materials has biostability and an impressive relative elongation value, which increases their ductility and durability when working in the inner layers of the roofing carpet. 
Izol is produced in two grades: without polymer additives (I-BD) and with plasticizing additives (I-PD). Izol is used as a waterproofing and vapor barrier, gluing it onto bitumen and bitumen-polymer mastics. The price of Izol is comparable to third generation surfacing materials. Pure polymer
In recent decades in Russia and in the last fifty years in Europe, polymer membranes have begun to be used in the construction of roofs of modern public and industrial buildings. Depending on the chemical compounds used, membranes come in several types: EPDM, TPO, PVC. The service life of membranes is from 25 to 40 years without signs of aging. One of the differences between the membrane and bitumen-polymer roll materials is the method of attachment to the base (mechanical) and the type of base itself. The membrane coating is made on a base of rigid mineral fiber boards by attaching the membrane strips with special dowels and connecting (fusion) the strips together using a construction hair dryer. The great advantage of membranes is the ability to install them at any time of the year..
Membranes are used both on the screed and on the existing roofing carpet with its special preparation. It is also practiced to permanently glue the membranes to the base using a special mounting adhesive. 
Despite all the apparent ease, the process of selecting and installing a membrane is not so simple. Labor costs for installing membrane roofs are 2 times higher than for installing bitumen-polymer roofs. If the membrane is used incorrectly, as with any roofing material, there is a risk, at best, of not taking advantage of modern and expensive materials, and at worst, causing damage to the contents of the building.
