Roofing roll material is the most popular way to finish the roof of any country house. The modern market offers a wide selection 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 depending on the type of base into basic or baseless. According to the type of components of the coating composition, they are bituminous, polymeric or bituminous-polymeric. 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. Consider the features of each type in more detail.
Bitumenous: cheap and easy
All roofing materials of this type allow you to equip a soft roof. The secret of their popularity is economy, but due to the short service life (only six years), the material is used mainly to cover temporary buildings, and not residential buildings. Roll propertiesroofing materials based on bitumen are such that they do not withstand weathering in the form of sunlight and temperature changes.
Types of bitumen materials
Rooferoid is the most popular among bituminous materials. It is widely used in country and individual construction, differing in low cost. The service life is a maximum of seven years, but it is widely used by individual developers. Ruberoid is a rolled bituminous roofing material, which is a roofing paper impregnated with bitumen. The upper part has a scaly or coarse-grained loose surface, and may be without it. The lower part is pulverized or fine-grained. Modern roofing material is roofing or lining. Installation involves gluing with hot or cold mastics or using roofing nails.
Pergamin is another material made from roofing paper and impregnated with bitumen. The material is thin and less durable compared to roofing material, so it is most often used as a lining.
Fusion Roofing Materials
Flat roofing is an excellent solution for arranging the roofs of buildings, structures in the field of industrial and civil construction. Such materials are suitable for waterproofing both roofs and foundations, floors and ceilings. Rolled roofing welded material is easy to install, so a large amount of work can be done in just a day. Its peculiarity is that as a basisrot-resistant fiberglass or fiberglass fabrics are used to increase strength.
As bitumen modifiers, polymers are used, which increase resistance to various influences and increase strength. Rolled roofing welded material is characterized by high elasticity, flexibility at low temperatures and high heat resistance. An important role in the welded materials is played by the structure of the upper layer, the task of which is to protect the roof. The roof covering should serve as protection against heating, ultraviolet radiation, precipitation. Sprinkle coating is used to minimize this effect.
Rolled roofing waterproofing welded material most often has a dressing of different fractions - coarse-grained or fine-grained, scaly or dusty. Bas alt, slate, sand, ceramic chips are used as raw materials. When choosing, you should focus on several factors:
- The complexity of the relief 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.
Bitumen waterproofing materials
A number of roofing materials serve not only to cover the structure, but also to provide high-quality waterproofing. Among them is metal insulation. This material has a three-layer structure: bitumen - foil - bitumen. It is a durable roof covering with excellent performance properties,with high strength and reliability.
Bituminous rolled roofing and waterproofing material called isol is no less popular. Rubber, mineral sealants, antiseptic and polymer additives are added to it during production. Such a composition serves as a guarantee that the material will show increased heat resistance. Suitable for covering flat roofs and ceilings. On the basis of asbocellulose, a hydroisol is created, the main difference of which is increased rot resistance. It is widely used in waterproofing basements and areas that are poorly ventilated.
Thus, roofing bituminous rolled and built-up materials are a wide range of coatings that are made in the form of canvases and can be used in various areas of construction. The secret of their popularity lies in their affordable cost, as well as increased resistance to various influences.
Bitumen-polymer materials
If the bottom layer in the form of a binder is glued to the welded roofing, it will show good waterproofing properties. Rolled roofing waterproofing welded material most often has a binder component in the form of roofing bitumen and fillers in the form of polymer additives, which affect the increase in service life and operational properties.
Oxidation of bitumen leads to an increase in heat resistance and a decrease in frost resistance of the coating. To avoid such phenomena, atactic polypropylene (APP) or styrene-styrene-butadiene elastomers (SBS). In this way, rolled polymer-bitumen roofing material is obtained. It costs more, but excellent performance combined with high reliability and durability will appeal to 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, crumb rubber or thermoplastic. This roofing roll material has a number of features:
- High plasticity.
- Crack resistance.
- Possibility of operation in different temperature ranges.
- High strength.
- Reduced brittleness temperature.
- Elevated softening point.
The use of bitumen-polymer types of coating is advisable when building a flat or pitched roof with a maximum slope of twenty-five degrees. Otherwise, the coating may slip. Roll roofing materials for the top layer based on bitumen and polymers are available 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 increaseoperational characteristics. This material comes in a number of varieties, the most popular being Copprflex with an inert copper outer layer and Aluflex with an aluminum outer layer. These coatings are highly heat resistant and durable.
Isoplast
Roofing material "Isoplast" consists of polymerized bitumen and 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 polyethylene film on the other, and the bottom layer is a polyethylene film, which is coated on both sides with a fine-grained fraction topping. Such a structure of the material contributes to the fact that it acquires flexibility, resistance 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 is the key to reliability in any temperature changes.
- High elasticity results in improved flexibility at low temperatures.
- The coating has good adhesion to the powder.
Among the most popular materials in construction, rolled roofing of the Technoelast series can be noted. They are produced by double-sided application on a base of polyesters orfiberglass bitumen-polymer binder. It, in turn, consists of bitumen, SBS modifier and mineral filler in the form of talc or dolomite. And the protective layer is created on the basis of sprinkling of different fractions and a polymer film. The coating is widely used in the creation of roofing carpet in various buildings that are operated in all climatic conditions.
Polymer roll roofing materials
Roll polymer roofing material is created on the basis of petroleum resins or rubber. These types of coatings belong to a new generation and have durability and high reliability. Their service life reaches twenty years or more, and they can cover roofs of any configuration - flat, pitched, gently sloping, and even with round slopes. Laying is carried out by strip or continuous gluing on the basis of adhesive mastic, and the preparation of the substrate plays an important role. Some materials are weighted or mechanically secured.
Polymer membrane
This is a modern roofing roll material, which is increasingly used in the repair and decoration of the roof. Its popularity is due not only to high reliability, but also to a wide range of colors, resistance to temperature extremes and durability, which reaches forty years. This innovative material is a single-layer roof, which is made from flexible polyvinyl chloride by hot air welding. This roofing is different:
- UV resistant;
- immunity tothe most adverse weather conditions;
- resistance to various bacteria, chemically aggressive substances;
- resistance to decay and decay;
- breathable coverage.
All this distinguishes this roll roofing material (GOST is set in the technical documentation) from others.
Types of polymeric 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 give elasticity. A special reinforcing base gives reliability and strength, while the seam areas are strong and tight.
Membranes based on thermoplastic polyolefins are an innovative material in which components are added to improve the fire and operational properties of the surface. Such membranes are characterized by a combination of the advantages of PVC and rubber. Therefore, they are better combined with bitumen. And this, in turn, affects the greater strength of the material.
EPDM-based membranes 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 package contains additional parts that can be used towaterproof difficult areas - sealants, fasteners.
Roofing materials by class
Depending on the durability, all bituminous roofing 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)
The Technoelast series can be attributed to premium class materials. The features of these coatings are the ability to create a breathable roof, from which moisture will be removed, which has the ability to reduce the durability of the roof. With the help of materials of this type, it is possible to equip a single-layer roofing, solving the problem with swelling and making the installation itself easier and more convenient. For the arrangement of the lower layer of the roofing, you can use "Technoelast Fix", which makes it possible to mount 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.
There are two business-class materials - "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 of these materials are a waterproofing sheet that provides roof ventilation. Ecoflex is an excellent solution for waterproofing roofs and underground structures. This roofing rollIt is expedient to use the material in regions with elevated temperature conditions. Due to its quality and reliability, it will serve as roof protection for quite a long time.
Among the materials of the standard class, "Bipol" is in demand. It has a strong, non-rotting base, which is coated on both sides with a high-class bitumen-polymer binder. On the basis of this material, it is possible to equip a roof with a small slope, waterproof the foundations of buildings and structures.
The economic types include "Linocrom K", with the help of which the top layer of the roofing carpet is equipped. It can be used as a vapor barrier in the bottom layer of the system. Its protective layer is made with fine-grained dressing or polymer film.
"Bikrost" is a popular material that is a waterproofing sheet with a strong base based on a bituminous binder. It is used when installing the bottom layer of the roofing carpet. The protective layer is provided with a fine-grained dressing or film. The cheapest roofing roll material is glassine. It is a roofing cardboard, which is additionally impregnated with oil bitumen. Based on this material, it is possible to repair and equip roofs with a maximum service life of five years.
