Types of soft roofing. Soft roof: reviews

One of the oldest methods of coatingsroof is considered a soft roof. Its history begins with the way a man stretched the bark of a tree or skin on the poles to protect himself from the sun and rain. Today, fur for the roof, of course, no one is using, there is a huge amount of other, much more effective materials. And also a lot of technologies with which you can make its device.

All types of soft roof have their shortcomings and advantages.

Advantages

Among the advantages of a soft roof are the following:

• the ability to arrange roofs of various complex shapes;
• ease of installation, without requiring the use of heavy equipment;
• excellent waterproofing qualities;
• good maintainability;
• low specific gravity;
• when rain does not create noise;
• not exposed to corrosion;
• when installing a small amount of waste;
• low cost.

Minuses

It should be understood that any kind of soft roof, despite the mass of its positive properties, have disadvantages. Although science and technology are not worth the space, and materials are constantly being improved.

So, the cons:

• the need for a solid foundation;
• low fire resistance;
• weak thermal insulation qualities;
• If a small area is damaged, it is required to replace the whole sheet.

Types of soft roofing

Only half a century ago the amount of materials for its device was limited to 2-3 names, among which were several types of roofing paper, and also only on the basis of bitumen-impregnated paper.

Today, the types of soft roof roofs are presenteda variety of materials on a diverse basis with different properties, scope and appearance. New varieties appear almost every day, so in this article, try to tell at least about the most common of them.

Flexible shingles

This is the so-called bituminous soft roof (speciesit can be of different shapes and colors, but we'll talk about it below). It consists of three layers. The outer - visible to us - is a stone colored crumb. Then comes the bitumen applied from 2 sides to the fiberglass. And the bottom layer is rubber-bituminous. Also it is glue. It should be noted that this type of roof provides maximum efficiency in terms of leaks (water resistance) and absolute tightness of the coating. Also its important qualities are absence of exfoliation, decay and corrosion. Also, when installing such a roof, the smallest percentage of waste. By comparison, waste when creating roofs from metal tiles reach 50%. At the same time, for flexible shingles, 5% is already qualified as very large.

This soft roof species has the most diverse. It is produced in the widest color range and a huge variety of shapes: hexahedrons, rectangles, semicircles; there is laminated and multilayered tiles.

Its advantage is the possibility of creatingroofing with complex geometry, which makes it possible to satisfy the demands of the most demanding customers, and also to realize the unusual intentions of architects. In addition, such a roof is absolutely noiseless material, because it has excellent sound insulation properties. The guarantee is an average of 20 years, but the actual service life reaches half a century.

Among the shortcomings of such a roof can be identifiedonly the cost, which is much higher than that of metal. This is due to the fact that this material requires a perfectly flat base (laths made of moisture resistant plywood or dry wood, which are not expensive). Its main producers are Ruflex, Icopal, Tegola, Tekhnonikol.

Roll roofing

It should immediately be stipulated that the roll is softroofing species has different. One of the most popular and cheap materials in this category is an ordinary, all-known roofing material. Its basis is bitumen-impregnated roofing cardboard. After such treatment, both sides are covered with a special layer consisting of a mixture of mineral filler and bitumen. The last stage of production involves coating the outer part of the roll with powder. It should be emphasized that such roofing felt from roofing is distinguished by the density of cardboard.

The life of such material is 5years. At the moment, the technology has changed a little, and polyester fabric or fiberglass canvas is often added to the cardboard. Changes in technology have made it possible to double the durability of material exploitation.

Another popular roofing material isRenemast, which is characterized as a floating bituminous material. Its main difference from roofing felt is in the high content of bitumen, which is located in the lower part of the canvas.

Similar types of soft roof, whose photospresented in this article, are called glass ruberoid, glass-insulator and glass-melt. Their basis is fiberglass. At the present moment, one of the most advanced options among roll materials is eurorebroid - it is a bitumen-polymer membrane.

After acquaintance with kinds of roll materialsa reasonable question arises as to how they are produced. Their manufacturing technology is uncomplicated. A special coating layer (mixture of bitumen and polymer additives) is applied to a substrate of glass fiber or polyester. The life of this material is about 20 years. Its only drawback is poor resistance to low temperatures, therefore, when laying it is necessary to provide at least 3-4 layers.

All roll materials are suitable for the deviceroof, which has an inclination of 45 °. Since the roll roofing paper has a sufficiently high level of water resistance, it is used even on flat roofs. Such materials are made in the form of panels, which are then cut and rolled into large rolls. Their width is generally 1 m with a length of 10-15 m.

Membrane roofing

This term should be understood as all kinds of soft roof roll type. Such materials are produced in different types:

• Polyolefin roofing.
• Thermoplastic roof.
• Ethylene-propylene-diene-monomeric roof.
• Polyvinylchloride roofing.

The polymer membrane in the west is already usedmore than 50 years, we have this material is known for about two decades. At the moment, in Europe, the polymer membrane accounts for about 80% of all roofing soft materials.

It is characterized by flexibility, highstrength, frost resistance, weather and ozone resistance, resistance to oxidation and exposure to ultraviolet rays. It also has a long life - its service life is about 50 years without repair.

Easy to usea considerable width of the membrane, this makes it possible to select the optimal size for the roofing of industrial buildings and large construction projects, which minimizes the number of seams. Mounting of the membrane roof can be performed throughout the year.

Soft roof: types, reviews

Today you can find a lot of positive feedbackrelatively soft roof. People note the possibility of creating roofs of various forms, the absence of noise in the rain, ease of installation. Of course, along with all the positive feedback can be found and negative, associated mainly with the need to create a solid foundation, which creates additional costs for materials and works of masters.

Roof installation

Many varieties have a soft roof, the types of work, therefore, also differ and depend on the selected material. Next, consider the general requirements for different designs.

Rafters

For a roof like this,differ from anything else from the roof structures. The only exception is that virtually all types of coating require crate from plywood, whose weight should be taken into account at the time of strength calculation.

Rims

Virtually all types of soft roof, as alreadyit was said, require a crate of plywood. An exception is the roof of ondulin, the slope of which is more than 12˚. In this case, a crate with a small step is possible, which is specified for each specific material.

Roof pie

There are many more features. In the event that the room in which the roofing device is being heated is heated, then another layer of insulation is required, all materials of this type having a very high thermal conductivity.

Almost always it is necessary to planvapor barrier membranes, in order to avoid damage to the crate and the formation of condensation. Some roll materials must be stacked in several layers. For a top cover layer, a separate sheet type is used for multi-layer packing.

In the article the most widely discussedapplied and known types of soft roofing. The use of any of these materials makes it possible to obtain an aesthetically pleasing, modern roof, as well as reliable construction with a long service life.
