Roofing material is considered one of the most budgetary and reliable materials in order to create a waterproofing barrier between the lower layers of the building coating and floor surfaces, between the roof and the attic. It is made by impregnating cardboard with bitumen, which is obtained from petroleum products.
Next, the top and bottom layers of cover bitumen are added. Some of the products are provided with a powder to increase reliability and resistance to abrasion. To choose roofing felt for the roof, you need to read these recommendations.

The best roofing materials RCP
The abbreviation of this product suggests the fact that roofing felt can be used to create the lower and upper sections of the roof. The thickness of the base, impregnation with bitumen and fine dust sprinkling make it possible to use it as a temporary roof for utility and technical buildings.
TechnoNIKOL RKP-350
A good roofing material in 2020 for the purpose of arranging a temporary roof at a construction site, where it is necessary to protect materials from negative weather conditions, when the main roof cannot be laid, and precipitation interferes with functioning and contributes to damage to objects inside.
The release of such an insulator is carried out in golden packaging with blue ornaments and inscriptions of a domestic developer. There are 10 or 15 m in a roll.
The bituminous surface is covered with a light dusting, which will increase the strength of the coating and make it possible to withstand wind and small amounts of snow. After winter, a permanent roof is dismantled and laid.
Pros:
- plasticity of the material, which will fully repeat the shape of the roof;
- heating up to 80 degrees is maintained without deformation and loss of qualities;
- reinforcing component - thick cardboard will provide adequate strength even for further walking on a temporary roof;
- the coating composition has the proper mass, which will make it possible to protect against abrasion;
- during longitudinal stretching, the canvas can withstand up to 28 kgf;
- in direct contact with moisture, water is absorbed no more than 2% throughout the day;
- the building is fully protected from moisture penetration;
- on each side a dusty rash that prevents sticking;
- will not rot;
- is not an electrical conductor;
- allowed to be laid on liquid mastics and mechanically (nailed to the crate).
Minuses:
- adequate price;
- sometimes it cracks somewhat when laid during severe frost over 40 degrees;
- rolls weighing 26 kg are difficult to feed to the top of the roof in large quantities.
The best ruberoids RPP
A similar material is used directly as a lining, as it is characterized by the lowest density and reliability to withstand an open load. During its manufacture, no solid bedding is used, which will facilitate installation due to the increased flexibility of the sheet. Due to the bituminous inner and outer layers, thermal and waterproofing is performed.
TechnoNIKOL RPP-300 (O)
It is the best roofing material in order to protect the basement and basement floors from the ingress of groundwater, as it has increased strength due to bitumen impregnation. As a result, the price of an analogue starts from 49 rubles. for 1 sq. m.The release is carried out in rolls, the total weight of which will be 20 kg, which makes it possible to easily bring it to the installation site.
Pros:
- the outer layer is not lost during transportation and installation;
- perfectly tolerates elevated temperatures up to 80 degrees;
- with direct contact with moisture, the absorbency will be no more than 2% per day;
- due to increased flexibility, it easily unfolds and fits into narrow spaces;
- the weight of the mastic material on the surface will be 500 g per sq. m, which will provide adequate insulation from water and freezing;
- it is possible to order 36 or 47 rolls on a pallet;
- the base has a cardboard density of 300 g per sq. m, which will ensure the transfer of pressure from above from movement.
Minuses:
- sometimes sticks together during prolonged storage and temperature surges;
- overcharge;
- you cannot buy less than 1 roll for small areas;
- you must be extremely careful not to tear the canvas.
KRZ RPP-300 S2
It is the best roofing material for creating an obstacle between floors, so that water and heat do not move up / down. It is laid deep into the roofing materials and the substrate, and only then the floor covering is mounted.
The production of roofing material is carried out in rolls of 15 m, where the price starts at 245 rubles. The domestic manufacturer highlights its own products with a diagonal inscription with the product brand and the roof logo, which emphasizes the guaranteed dryness after the material has been used.
Pros:
- adequate cost;
- the density of the cardboard provides the necessary strength so that the pressure from the floor material and walking does not provoke a breakthrough of the base;
- from above it is allowed to lay a concrete screed and mount a warm coating, since the bituminous material can withstand temperature indicators up to 80 degrees;
- small mass of a roll, which does not interfere with unloading and delivery to the upper floor;
- 53 or 61 rolls are delivered on a pallet, which is comfortable for a large object;
- increased flexibility makes it easier to lay in tight areas;
- the weight of the outer layer of bitumen will be 350 g per square meter, which perfectly insulates sound and heat transmission;
- easily cut with a knife or with scissors;
- does not absorb moisture;
- since there is no sprinkling, the outer layer is not lost over time;
- creates an obstacle to the formation of fungus thanks to natural oil impregnations.
Minuses:
- the material has no sprinkling, therefore, with prolonged storage in a roll, it sometimes sticks together;
- resistance to longitudinal stretching is less than in other varieties and will be 22 kgf, therefore, care will be required during installation.
The best roofing materials RKK
One of the most expensive types of roofing material due to its reliability. The material is intended for the final layer of the roof, has a coarse sand coating, which increases the resistance to abrasion. Used on all types of flat and pitched roofs as a top layer.
TechnoNIKOL RKK-400
A good roofing material for the roof of a multi-storey building, on which all kinds of service companies (Internet, antenna, electricity) will constantly walk. The density of the cardboard base will be 400 g per sq. m, and the weight of the outer layer will reach 800 g per sq. m, which will provide increased wear resistance and cut resistance.
Pros:
- it will take a lot of effort to break the web;
- increased heat resistance, which tolerates summer heat well;
- while creating a moisture pressure of 0.01 kgf per sq. cm can withstand its presence for 3 days with full moisture resistance;
- does not form cracks during bending;
- large crumb on the outside will protect against abrasion.
Minuses:
- during arson, it supports combustion, since it belongs to the G-4 subgroup;
- a roll weight of 28 kg creates difficulties during the delivery of large batches upward;
- in case of careless transportation, the loss of coarse-grained powder appears.
RKZ RKK-350 TU
It is the best roofing material for garage roofing, since its strength characteristics will be 32 kgf with longitudinal tension, which ensures withstanding a strong gust of wind and does not tear off the sheets.
The surface is supplied with coarse-grained chips, which increase the strength parameters of the outer layer, therefore it is possible to move around the garage without fear when necessary. The material will perfectly tolerate direct sunlight and will not deform when heated to 80 degrees.
Pros:
- increased density of the cardboard base, perfectly tolerates vertical load;
- it is possible to order 30 rolls on a pallet;
- covering materials weight up to 800 g / sq. m will provide increased wear resistance;
- difficult to break even deliberately;
- ordinary masonry with fasteners or liquid substances;
- excellent moisture resistance;
- perfectly tolerates jumps in temperature indicators;
- long service life.
Minuses:
- overcharge;
- impressive roll weight.
The question often arises which roofing material is better. To know how to choose roofing material, you must take these recommendations into account. The rating includes the best products. They are characterized by reliability and quality.
