Roofing roll material: types and composition

Roofing roll material - the most popular way of finishing the roof of any country house. The modern market offers a wide range of materials, each of which is good in its own way. What to give preference and what to look for when choosing?

Main Categories

All roll materials for roofing are divided according to the type of basis on the basic or non-basic ones. By the type of components of the coating composition, they are bituminous, polymeric or bitumen-polymer. The substrate can be cardboard, asbestos, polymers, glass fibers 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 consider the features of each type in more detail.

Bituminous: cheap and simple

All roofing materials of this type allow the construction of a soft roof. The secret of their popularity is in economy, but because of their short service life (only six years), the material is used mainly to cover temporary buildings, rather than residential buildings. Properties of rolled roofing materials based on bitumen are such that they do not withstand the atmospheric effects of sunlight and temperature changes.

Types of bituminous materials

The most popular among the bituminous materials is ruberoid. It is widely used in dacha and individual construction, differing in small cost. The service life is a maximum of seven years, but it is widely used by individual developers. The ruberoid is a roofing material made of bituminous bitumen, which is a roofing cardboard impregnated with bitumen. The upper part has a scaly or coarse granular surface, and maybe even without it. The lower part is pulverulent or fine-grained. Modern roofing felt can be roofing or lining. Mounting involves gluing with hot or cold mastics or using tolevy nails.

Pergamum is another material, which is made of roofing cardboard and impregnated with bitumen. The material is thin and less durable than a roofing material, so it is often used as a lining.

Weldable roofing materials

Welded roofing is an excellent solution for arranging roofs of buildings, structures in the field of industrial and civil construction. Such materials are suitable for waterproofing both roofing, and foundation, floors and ceilings. The roll roofing material is easy to install, so you can do a lot of work in just a day. Its peculiarity is that as a basis, glass fiber cloth or fiberglass resistant to decay, which increase strength, is used.

As modifiers of bitumen used polymers, which increase the resistance to various effects and increase strength. The roll roofing material is highly elastic, flexible at low temperatures and high heat resistance. An important role in the deposited materials is played by the structure of the upper layer, whose task is to protect the roof. The roof covering should serve as protection from heating, ultraviolet radiation, precipitation. To minimize this effect, a coating is applied.

The roll roofing waterproofing deposited material most often has a powder of different fractions - coarse-grained or fine-grained, scaly or pulverized. As raw materials are used basalt, slate, sand, ceramic crumb. When choosing one should be guided by several factors:

1. The complexity of the relief of the roof structure, as well as the angle of its slope.
2. Temperature regime in the region.
3. The amount of precipitation, which falls on average for the year.
4. 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 for its high-quality waterproofing. Among them - metal. This material has a three-layer structure: bitumen - foil - bitumen. This is a solid roof covering, showing excellent performance properties, with high strength and reliability.

No less popular bitumen roll roofing and waterproofing material called isol. In it, rubber, mineral seals, antiseptic and polymer additives are added during production. Such a composition serves as a guarantee that the material will show increased heat resistance. Suitable for covering flat roofs and ceilings. Based on the asbestos-cellulose hydroisol is created, the main difference of which is increased rotting resistance. It is widely used in the waterproofing of basements and areas that are poorly ventilated.

Thus, roofing bitumen roll and deposited materials is a wide choice of coatings that are made in the form of canvases and can be used in various construction sectors. The secret of their popularity - at an affordable cost, as well as increased resistance to various impacts.

Bitumen-polymer materials

If the glued roofing is glued to the bottom layer as an astringent component, it will show good waterproofing properties. The roll roofing waterproofing deposited material most often has an astringent component in the form of roofing bitumen and fillers in the form of polymer additives, which affect the increase in service life and performance.

Oxidation of bitumen leads to an increase in heat resistance and a decrease in frost resistance of the coating. To avoid these phenomena, atactic polypropylene (APP) or styrene-butadiene-styrene elastomers (SBS) are added. In this way, the material is a roll polymer-bitumen roofing material. It costs more, but excellent operational properties in combination with high reliability and durability will be to the liking of many owners of country houses.

Features of bitumen-polymer materials for roofing

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, rubber crumb or thermoplastic. Such roofing roll material has a number of features:

1. High plasticity.
2. Resistance to cracking.
3. Possibility of operation in different temperature range.
4. High strength.
5. Reduced temperature of brittleness.
6. Increased softening temperature.

The use of bitumen-polymer coating types is advisable when erecting a flat or pitched roof with a maximum gradient of twenty-five degrees. Otherwise, the coating can slip. Roofing materials for the upper layer based on bitumen and polymers are presented in several types.

"Monoflex"

This is a multi-layer material consisting of polyester, film, polymerized bitumen as a base and a coating in the form of ceramic chips. Thanks to modified additives, it is possible to improve performance. 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"

Roof material "Izoplast" consists of polymerized bitumen and a base in the form of polyester or glass wool. It is available in two varieties - roofing and lining. The top layer has a coarse-grained sprinkling on the front side and a polyethylene film on the other, and the lower layer is a polyethylene film that is coated on both sides with a fine-grained fraction. This arrangement of the material contributes to the fact that it acquires flexibility, resistance to breakage at the bend and the formation of cracks. Polymer film from below serves as protection of the coating and guarantees its preservation.

Other bitumen-polymer materials

Any roofing material based on bitumen and polymers has a number of advantages:

1. The high quality of the binder component is the key to reliability in any temperature changes.
2. High elasticity affects the improvement of flexibility at low temperatures.
3. The coating has good adhesion to the coating.

Among the materials popular in construction, it is possible to note roll roofing coatings of the "Technoelast" series. They are produced by two-sided application on a basis of polyester or fiberglass bitumen-polymer binder. It, in turn, consists of bitumen, SBS-modifier and mineral filler in the form of talc or dolomite. A protective layer is created on the basis of the sprinkling of a different fraction and a polymer film. The coating is widely used in the creation of a roofing carpet in various buildings that are operated in any climatic conditions.

Polymeric roll roofing materials

The roll polymer roofing material is created on the basis of petroleum-polymer resins or rubber. These types of coatings belong to the new generation and have durability and high reliability. The term of their operation reaches twenty years and above, and they can cover roofs of any configuration - flat, sloping, gently sloping and even with round slopes. Stacking is performed by strip or continuous gluing based on adhesive mastic, and the preparation of the base plays an important role. Some materials are attached by a load or by mechanical means.

Polymer membrane

This is a modern roofing roll material, which is increasingly used in the repair and decoration of the roof. Its popularity is determined not only by high reliability, but also by a wide range of color solutions, resistance to temperature changes and durability, which reaches forty years. This innovative material is a single-layer roof, which is made of flexible PVC with hot air welding. This roofing is different:

• Resistance to ultraviolet radiation;
• Immunity to the most unfavorable weather conditions;
• Resistance to the effects of various bacteria, chemically aggressive substances;
• Resistance to decay and decomposition;
• The possibility of creating a coating with a breathable effect.

All this distinguishes this material roll roofing (GOST is set in the technical documentation) from others.

Types of polymer membranes

Membranes based on PVC are the most common in Russia. They consist of polyvinyl chloride, in which plasticizers are added. Their purpose is to increase frost resistance and give elasticity. The special reinforcing base gives reliability and durability, while the joints are durable and sealed.

Membranes based on thermoplastic polyolefins are an innovative material in which components are added that improve the fireproof and operational properties of the surface. Such membranes are distinguished by a combination of 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 a high elasticity and ability to be used for a long time under the most extreme conditions. They are produced reinforced and unreinforced, which is necessary to increase the strength and reliability of the material. In this case, any variety is characterized by elasticity and strength. The kit consists of additional parts, with which you can waterproof difficult areas - sealers, fasteners.

Roofing materials by class

Depending on the durability, all roofing bituminous 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);
• Subeconom (service life is not more than five years)

Among the materials of the premium class is the "Technoelast" series. Features of these coatings - the ability to create a breathable roof, from which moisture will be removed, which has the ability to reduce the longevity of the roof. With the help of this type of materials, it is possible to equip a single-layer roof covering, solving the problem with blisters and making the installation itself easier and more convenient. To arrange the lower layer of the roofing coating, you can use the "Technoelast Fix", which makes it possible to mount a roofing carpet on the base. The roof will be resistant to deformation and capable of withstanding heavy loads. The operational features of the coating are such that it can be used in regions with any climatic conditions.

Among the materials of the business class can be identified two - "Uniflex" and "Ecoflex". The first is good because it serves as an effective protection against moisture penetration, contributing to the durability of the structure. Both that and other materials are a waterproofing sheet that provides ventilation of the roof. "Ecoflex" - an excellent solution for waterproofing roofs and underground structures. This roofing roll material is advisable to use in regions with elevated temperature regimes. Due to its quality and reliability, it will serve as protection of the roof for a long time.

Among the materials of the standard class, Bipol is in demand. It has a strong, non-spinning base, which is coated on both sides with bitumen-polymer binders of high class. On the basis of this material, it is possible to equip the roof with a small slope, to waterproof the foundations of buildings and structures.

Economical types include "Linocrom K", with which the upper layer of the roofing carpet is arranged. It can be used as a vapor barrier material in the lower layer of the system. The protective layer is made by fine-grained powder or polymer film.

"Bikrost" - a popular material, which is a waterproofing sheet with a solid foundation based on bitumen binder. It is used for the installation of the lower layer of roofing carpet. The protective layer is provided with a fine-grained powder or film. The cheapest roofing roll material is a glassine. It is a roofing cardboard, which is additionally impregnated with oil bitumen. Based on this material it is possible to repair and equip the roof with a service life of a maximum of five years.

conclusions

As you can see, modern manufacturers offer a wide choice of roofing roll materials. Each of them has its own technical and operational features, each designed for a specific design of the roof. That is why it is so important to take into account the composition, application features and climatic conditions of your own region. All this in combination will allow you to select the most suitable building material for the specific conditions.
