Soft roofing material has gained its popularity for a long time, which is why it does not lose its position even in the most difficult economic conditions. More and more new materials for soft roofing began to appear, as well as growing purchasing power and a noticeable expansion of their scope.
When constructing a roof made of soft material, a wide variety of materials are used:
- Mastic of different types.
- polymer membranes.
- Roll material.
- The tile is bituminous.
Soft roofing materials have high flexibility, strength, water resistance, have excellent anti-corrosion and anti-fungal properties, have excellent sound and heat insulation.
Taking into account all these advantages, we can say that this type of material is great for any type of roof:
- Large commercial.
- Warehouse objects.
- Production facilities.
- Private cottages.
Advice. First, when choosing a soft roofing material, first of all, it makes sense to pay attention to the value of heat resistance indicators. After that - for mechanical strength, elasticity and flexibility.
Complementing this, it should be noted that adhesion indicators, total curing time and the volume of dry residue content are important for mastic. Also, do not forget about such an important characteristic as durability.
Roll material
The most inexpensive and most popular in this group of materials is ordinary roofing material.
For its production, a roofing cardboard base is used, which is impregnated with bitumen. After that, a cover layer is applied on both sides, consisting of a mixture of harder bitumen with mineral filler.
At the final stage of production, the outer part of the entire roll is covered with a special powder. In turn, the difference between roofing and impregnating roofing material lies in the higher density of the cardboard used in production.
Soft roofing materials serve at best for about five years. Today, very often, manufacturers make it on the basis of the same cardboard, but with the addition of fiberglass canvas, fiberglass or polyester fabric.
Thanks to the introduction of a more advanced technology in this way, the durability of the roofing material is doubled.
There is also another roofing material called "rubemast". It is a bituminous build-up material, which differs from roofing material in the increased content of astringent bitumen on the underside of the web.
An identical material, which is based on fiberglass, is called glass roofing material, tecloizolol and glass mast. To date, the most modern option from the family of rolled materials is a roofing polymer-bitumen membrane - euroroofing material.
Many are interested in how rolled roofing is made - the technology for its manufacture is simple.
As a basis for a design such as roll roofing, fiberglass or synthetic polyester base is used. A cover layer is applied to this base, made by mixing bitumen and some polymer additives.
This type of material can serve you for at least 20 years, but it is not very durable at lower temperatures, it is for this reason that the laying process requires 4 layers.
The use of all roll materials is allowed for use on roofs with such an indicator as roof pitch at 45°.
In this range of slopes, all soft roof material can provide excellent water resistance, which is why it is also used on flat roofs and pitched roofs.
This type of material is supplied in the form of panels, which are rolled into rolls during production. The width of the roll is usually 1 m, and the thickness varies from 1 to 6 mm.
Bituminous tiles
Bituminous shingles are another type of bituminous material, which are small flat sheets cut from bituminous rolls made from fiberglass. One such sheet shows 4 tiles.
By resorting to the help of dyes, you can create various kinds of color and texture solutions:
- Natural tile flooring.
- Moss-covered old surface.
- Old surface overgrown with lichen.
Both types of soft roof and its shape are diverse:
- Rectangle.
- Hexagon.
- Wave.
This type of material, although it is a piece, can also be attributed to soft roofing, for the reason that its structure and place of application are similar to rolled materials.
This type of material will last for 15 or even 20 years. It is possible to use these components for soft roofs only on pitched roofs, the minimum slope of which can be at least 10 °. The maximum slope level is not limited.
Covering with soft tiles can also be carried out on the vertical sections of the walls adjacent to the roof.
It is allowed to use sheets of bituminous tiles both when laying a new one, and when carrying out reconstruction work on an old roof. The only difference is that in the second case, bituminous sheets must be applied directly over the damaged coating, cleaned and prepared.
The main advantages of a soft roof, first of all, lie in the possibility of its use on roofs of any complexity, as well as various shapes and configurations, even on domed and triangular sections. At the same time, the roof will also have excellent sound-absorbing properties.
Roofing mastic
Roofing mastics according to the method of their application can be hot or cold. The main advantage of hot mastic is its rapid hardening.
Roofing from this material will be called mastic. When using cold mastic, the roof will be called "bulk".
According to the composition, the following mastics are distinguished:
- bituminous.
- Bitumen-polymer.
- Polymer.
Besides, mastics for the roof can be produced in one-component and two-component. One-component mastics are supplied ready for use.
Two-component products are available in the form of two formulations, which must be mixed together before use. These mastics can be stored for a very long time.
Mastic, on the surface of the roof forms a homogeneous monolithic coating. The manufacture of a soft roof can be carried out with the addition of dyes to the mastic, which will allow you to get the desired color.
In order to improve the strength characteristics, the coating can be reinforced with fiberglass canvas or glass mesh. Reinforcement can be made not only completely, but also partially, for example, at the junction of structures.
It should be noted the main advantage of mastic type coatings, which is the complete absence of not only joints, but also seams.
Advice. The main thing, when organizing this type of roofing, is the thoroughness of the work, which consists in maintaining a uniform thickness and ensuring the continuity of the entire coverage area.
polymer membrane
This term "roofing membrane" means various soft roll roofing.
The polymer membrane is produced in four types:
- Polyvinyl chloride.
- thermoplastic
- Polyolefin
- Ethylene-propylene-diene monomer, that is, from synthetic rubber.
This material has been widely used abroad since about 65 years. At the moment, they occupy 80% of all roofing materials on the European market.
In our country, polymer membranes began to be used only from the end of the 90s, and they became widespread only in 2003, when large international investors and construction companies came to the country and began mass construction of retail chains, offices and logistics centers.
Polymer roofing materials for soft roofs have high strength, elasticity, frost resistance, weather and ozone resistance, resistance to oxidation and mass exposure to ultraviolet radiation.
In addition, the roofing membrane is durable. The manufacturer of the roof guarantees up to 50 years of maintenance-free service.
Convenience is provided due to the large width of the membrane, which allows you to choose a more optimal width when organizing the roof of large buildings, and also allows you to minimize the total number of seams.
Work on the organization of the roof is allowed to be carried out throughout the year.
Thus, the article discusses all the popular and available materials for soft roofing on the market. Using almost any of the described materials, you will get a modern, high-quality and reliable roof, which, moreover, will have an aesthetically pleasing appearance and a long service life.
