Materials for the repair of the roof of the roof must comply with the existing requirements.It is not just their appearance, but also service properties.Modern roofing materials for the roof must protect the building from negative influence of external factors.In the first place from the wind, rain, snow and other precipitation.There is a better material for the roof of the roof?Let's try to understand this further.
General
on the market today presents various kinds of materials for roofing roofs.Are classified depending on the coating characteristics.Therefore, choosing the material for the roof of the roof, consider the following:
- Appointment building.Structures can be residential, industrial, commercial, household.In accordance with the selected coating with various properties.For example, the material for the roof of the garage roof appearance may not be as attractive as for residential buildings.
- expected life of the coating and construction in general.
- suitable material for the roof of the other elements of the roof structure.
- complexity of installation and subsequent maintenance.
- conformity with modern trends.
- Noise protection and heat-saving properties.
main classification
coatings are divided into:
- Heavy.
- easily.Having
- / non-waterproof surface.
- Other.
specialists note that absolutely perfect and universal coverage does not exist, for that matter, there is no perfect test "perfect."However, it is important to include material for a roof truss roofs must comply with the system and other elements of design and construction in general.
coating composition
According to this index the material for the roof of the roof can be:
- minerality.
- metallic.
- Organic.
In a large range on the market today presented materials the latter category.In the old days, the most popular of organic coatings have been shingle and straw.Modern roofing materials for the roof of this type can last from 5-7 to 25-30 years.These include, in particular, should include bitumen-polymer, polymer and bitumen coating.The disadvantage of these coatings is the instability to oxygen and UV rays.Under the influence of these factors, the materials wear out quickly enough, some may rot.All combustible organic coatings.Slightly less than a range of mineral (also called "stone") materials.Until recently, this category was common slate tiles and ceramic tile.Today there were more modern coating.In particular, the asbestos cement sheets (slate) and cement-sand tile.These materials are more durable than organic.Mineral coatings are resistant to UV rays and are less susceptible to rotting.However, they are quite poorly tolerate temperature changes.By the metal coating include sheet materials.The feedstock used copper, zinc, steel.Galvanizing, in comparison with other coatings this category, not as durable.Its service life - no more than 50 years.But copper and zinc coating can last up to 100 years.
Other classification
sheeting for roofs roofs can be:
- Metallic flat or profiled.
- Bitumen-fiber (synthetic fiber impregnated with bitumen).
- asbestos cement (metal, Ondulin and others).
- colored polymer (Slate).
material for the soft roof of the roof can be:
- roll (asphalt, roofing material and its modifications).
- film (rubber and polymeric membranes).
- pieces (natural slate, tiles, soft included).
- mastics (asphalt and resins).
However, the present separation can be considered completely arbitrary, because, for example, some piece and sheet materials differ only in size.
Slate
This material for the roof of the roof are always in demand.One of the advantages of its coverage is considered relatively low cost.As part of the slate used Portland cement and asbestos SHORT.The first component comprises 85%, the second - 15%.After solidification formed reinforcing mesh asbestovolokna.It gives the tensile strength and toughness.Slate is durable and fire-resistant coating.European counterpart material are more durable because they contain specialized lining of metal.Builders say the ease of installation and removal of slate.For fixing using special screws or nails.To prevent the flow of coating at fixing with rubber pads.One of the significant disadvantages of slate is possible to use them only on sloping structures.In addition, under the influence of precipitation on the surface microcracks appear.When the infiltration of water damage become larger, which leads to the destruction of the coating.To increase the service life and improve the decorative properties of the sheets of slate in the manufacture of coated pigment composition.As a result, formed on the surface protective layer.Thanks to him, the slate is one and a half times longer, and the release of asbestos into the air is less intense.
Bitumen-fibrous sheet
This material for the roof and the roof of the house has another name - "evroshifer."It is similar to the above-described coating.Euroslate belongs to the category of modern materials.In Russia, the common name of this coating is ondulin (by popular brands).Leaf shape is similar to slate.A distinctive feature of Ondulina considered ease of handling and higher strength.The coating has a low weight.This allows you to put it on the roof without removing old material and strengthening truss system.Sheets evroshifer able to withstand wind and snow loads.Another analog is covering, which is used in the manufacture of uniform polymer.In the production method using extrusion.Also during manufacturing pleated sheets.The advantages of this coating are strength, light weight, fire resistance, resistance to acid and alkaline environments, ecological, variety of colors and durability.However, this material can be laid on the roof with a slope of not less than 15%.
New coatings
Today is very popular material for the soft roof of the roof.When making use cardboard or another, are not affected by rotting materials.In particular, it is used in the manufacture of fiberglass, polyester or fiberglass.They were covered with either a pure bitumen or mixed with the polymer.These coatings are divided into:
- SBS modified.They contain at least 10-12% of the polymer component.Such coatings are characterized by high flexibility even at lower temperatures.
- APP modified.They contain from 25% of the polymer component.Such coatings are characterized by high heat resistance.
materials of the second category are mainly used in areas with hot climates, from the first - in the weather conditions in Russia.
Simple bitumen-roll coating
These include various types of roofing material, which are based on cardboard, metalloizol,null, foil and others.Such coatings are used in the device, hydraulic and vapor barrier.Roofing and roofing material veiled backing pitched and flat roofs.One of the major drawbacks of these coatings should be regarded as their small operational life - no more than five years.Roll materials have increased sensitivity to atmospheric conditions.They do not tolerate temperature changes, UV radiation and precipitation.Many aspire to save and acquire such coatings.Subsequently, however, this initial low price will result in significant financial costs.Better quality are the materials of which consists of a layer of foil: metalloizol and foil insulating.
Improved coverage
At arrangement of the upper and lower layers of roofing and waterproofing used when installing roll materials based on glass, polyester or glass fiber.Among them, for example, it is worth noting rubestek, Bikrost, linokrom, rubemast, glass.Typically, they are used on flat and pitched structures (with a slope up to 25%).If the slope is greater, the high temperature material can slide off the roof.To fix the coatings used mastic.Another disadvantage is the need for a multi-layer assembly with gravel and rock dust.In general coating life of about 15 years.
Piece coverage
This category includes tiles, translucent and metallic materials for roofing roof (photo you can see some examples in the article).Such coatings are mostly laid on the roof and hipped designs with large bias.By the distribution of materials in this category should include ceramic tile, slate shingles and slate.Last characterized by durability and high decorative qualities.Shingles is a wooden plank with a wedge-shaped grooves and cross section.Lay them in several layers.Ceramic tile is considered enough "old" coating.This material is characterized by environmental friendliness, durability (service life of more than one hundred years old), as well as high quality characteristics.Today the building is used in three types of tiles:
- grooved.In this case, the stacking upper and lower rows is carried out the opposite side.This creates the effect of grooves.
- slots.Such a coating is laid as a "shell."For fixing elements to each other using the tool joint.
- flat.It is also called "beaver tail".When installing the top element covers the joint between the two lower.
There is also a cement-sand tile.It is used in its manufacture quartz sand, iron oxide pigments and Portland cement.This coating does not fade in direct sunlight, high durability and long service life.In addition, the fireproof material, has good sound insulation and low thermal conductivity.Stack coverage is better on a pitched roof.Installation can be done with their own hands without the involvement of teams of specialists.
Metal
Today, this material is the most common.The advantages of the metal coating should include hygiene, high strength, flame resistance and low weight.Among the disadvantages is worth mentioning susceptibility to corrosion, heat and sound conductivity good.In the manufacture of sheet material used as well as single-part materials: steel, duralumin, copper and gold plates, sheet metal roofing.To mount cover is necessary to attract professionals.The most popular to date, and galvanized iron sheets.They are covered with a special protective layer of an alloy of copper, titanium and zinc, which prevents the occurrence of corrosion.
