Which roof to choose: types of roofing
Roofing element, in which the edges are prepared for seam connections.
Falts(folded joint) - the type of seam formed when joining sheetsmetal roof. Distinguish seam connectionsroofingrecumbent and erect, single and double.
Installation of a faltsevy roof:
During installation and repairfolded roofthe lateral long edges of the strips of steel, which run along the slope, are joined by standing seams, and the horizontal ones - by recumbent ones. When constructing a folded roof, the paintings are executed (rolled up) either manually with a special tool, or with a more modern method - with special electromechanical sealing devices.
Currently, a single standing seam can be performed as a self-snap seam, but it has a rather serious minus - in the winter-spring period, leaks are inevitable in places of snow accumulation since single rebate is not tight! The most airtight and watertight is a double standing seam - this is a longitudinal connection,projecting above the folded roof plane between two adjacent roofing paintings, the edges of which have a double bend. We do not recommend installation and repair.folded roofon one fold, if the roof is complex or with a small angle of inclination. Due to the advantages of the double fold, it began to be used as the main one. Todayfaltsevy roofsin Western countries, they are mainly carried out with the use of a double - standing seam. Fold roof can be performed both in the attic and in the attic. Before mounting the folded roof, it is necessary to prepare the batten, the sheathing step depends directly on the slope of the roof slopes. The gutter system of seam roofs can be either classical - the external gutter is attached to the frontal panel of the eaves, and is located directly on the roof of the roof - a standing gutter. The standing gutter gives slopes to the drainpipes, and along this gutter water flows to the drainpipes. This design is the most reliable to date. Great attention is paid to the quality of fastening the sheets to the crate, which allows you to completely avoid leakage and excessive noise during rain and wind. However, if you wish, you can order the installation of a folding roof with a single fold.
Repair of a faltsevy roof:
When repairing a folded roof, if there is a need to partially change the metal, then you can make out a picture of the metal and replace it with a new one. Both during installation and repair of a folded roof, it is necessary to comply with the technology of folding of roofs, perform crate quality, seriously consider fastening pictures and their joining to each other.
The main advantages of seam roofs are:
- The smoothness of the surface of the folded roof, ensuring a good runoff of water;
- Possibility of industrialization of construction with preliminary mechanized procurement of roofing elements;
- Low weight, making it possible to arrange lighter support structures (rafters and crate); The flexibility of roofing steel, allowing to cover the roofs of complex shape;
- Non-flammability and non-flammability of the roofing;
- Simplicity of repair of faltsevy roofs;
The service life of a properly made folding roof is over 30 years. The warranty on the installation (device) folding roof 3 years.
Disadvantagessteel roofsshould include high thermal conductivity, which leads to the formation of icicles on the roof in the winter, as well as low resistance to shock, causing damage.The coating itself is quite smooth and given the above disadvantages, it is prone to avalanche of snow and ice, which leads to an increase in the cost of systematically clearing snow and knocking down icicles and if this procedure is not done by professionals, then most likely you will have to repair the roof in spring, careless snow removal and roof maintenance cause leakage!
Copper roof- roof for ages! Roofs made of copper hundreds of years ago, delight our eyes with the color of the sea wave now. Copper is considered to be the best roofing material in the whole world; the most modern technologies have not “invented” any, even close, similar material in terms of durability. When planning the installation of a copper roof, you should understand that a copper coating will serve you for more than a dozen years, even a hundred ..
Proceeding from this, it is desirable to select a roofing system that is suitable in terms of durability. You should not include materials into the roofing pie, the service life, which is several times lower than that of a copper roof.During the first year of "life", copper turns reddish brown, and then turns into dull black, and only after 15-20 years.Copper roof"Dressed" in malachite green outfits. There are artificial ways to patinate copper (changing the color of copper to malachite green), even before mounting copper, but they are very expensive. Copper patina is the natural protection of copper from an aggressive environment, patinated copper is virtually invulnerable.
Copper roof repair:
Copper roofdoes not require maintenance and reduces operating costs to zero. In this regard, the repair of copper roofs is very rare, can occur only in cases where the supporting roof structures (roof system) need to be replaced, or the project is changed due to the upcoming reconstruction of the roof or the building as a whole. More often repair of a copper roof is necessary in case errors were made during installation of a roof or a roof in general. Sometimes, with illiterate maintenance of the roof (snow removal, ice from the roof), a roof covering breaks through, in this case repair of the copper roof is also inevitable, otherwise leaks will become your companions and will remind yourself for a long time.tin copper. Also, since time immemorial, the method of soldering or tinning of copper has been used, when tin is used. The above makes repairing copper roofs easier and makes it possible to repair mechanical damage by welding on patches.
Installation of copper roof:
Mounting technologycopper roofIt is similar to the installation of a galvanized steel folded roof, the differences are only in the composition of the materials and as a result there are minor differences in the components and the approach to the installation of paintings. Due to its flexibility, copper can be roofed, in fact, of any complexity. Due to the fact that the folded steel is denser copper, the folded roof can be laid on the stepping purlin, however, the copper picture must be mounted on a solid purlin. For laying copper rolls using the method of "folding". Both single and double rebates are used, professionals prefer double rebates when installing copper roofs, since double rebate is super reliable! Modern equipment allows you to make a double rebate with amazing reliability and in addition to increase the speed of production of "folded paintings", the equipment requires electricity of 220 or 380 volts.
Installation of copper paintingsdocked double fold allowed on the roof with a slight slope, which greatly expands the range of copper onvarious roofs.
Briefly about the advantages of a copper roof:
- Service life, subject to technology installation up to 100-150 years;
- No maintenance costs; Ecological purity;
- The possibility of repairing copper coating.
Disadvantages of a copper roof:
- The price is quite high, although the advantages described above rightfully override this disadvantage;
- All metal roofs “rustle” during rain and strong gusts of wind, although the level of this noise is insignificant;
Copper is an excellent conductor of heat, and poorly insulated roofs easily overgrow frost, frost also forms in places bordering warm pipes, gutters, gutters, etc.
However, you can easily get rid of these shortcomings by installing a system of anti-icing.
Description of natural tile:
Natural tile (clay) and cement-sand tile is one of the most ancient roofing materials. It is durable, fire safe. Natural tile does not require frequent repairs and painting.A cottage with a tiled roof, an earthen baked or cement-sand one looks more attractive and richer, and the service life of such a roof without overhauling a tile exceeds 100 years. The tile has always emphasized its majestic superiority over the materials of analogues, unlike metal roofs, it is a good sound insulation, and low thermal conductivity along with the massiveness of the tile maximally reduces the formation of condensate on the inside of the tile, which increases the life of the batten.
Natural tile is used in countries with different climatic conditions and has a wide palette of colors.
The guaranteed service life of natural tile is 30 years.When choosing a natural tile, we recommend paying attention to the quality of the purchased batch.High-quality tile has a high density and low porosity of the composition. It is also necessary to buy material with all certificates, otherwise you risk returning to the issue of repairing tiles and it can become your regular companion. Features of installation and repair of natural tile: Natural tile can be mounted on buildings with a slope of at least 22 degrees and not more than 60 degrees.
When cornerroofingexceeds 60 degrees, the tiles need to be additionally fixed with clamps or screws to the roof lathing; however, it is necessary to perform a continuous crate in order to distribute the load. There are no differences in the technology of mounting or repairing natural tile and cement-sand tile, the difference is only in the composition of materials and molds of materials. It is necessary to plan the installation of natural tile before installing the truss system, since This tile has a lot of weight and rafters must be further strengthened to avoid sagging of the truss system and the risk of roof collapse! You can tile both attic (living space) andattic roof(non-residential roof). For comparison with a metal roof, a roof of natural tile needs to make the roof system 30% more powerful. Natural tile belongs to a number of elite roofing, the cost of installation and repair of natural tile is not a cheap pleasure, but this tile is worth it.To repair a natural tile, it will be necessary to remove several rows of tile, depending on the task and replace it with a whole. In other words, when repairing tiles, it is not necessary to change the entire roof, you can easily replace the broken fragments. Roof maintenance costs are minimal. Sometimes a well-installed tile roof serves as much as the house itself.
thereforeroofmade of ceramic tiles is a good investment. The disadvantages of a natural tile roof include relative fragility and a decent weight, although a lot of weight cannot be called a disadvantage, since at installation of a natural tile under it do the strengthen rafter system.
Ceramic tile (clay)somewhat more expensive than cement-sand tiles, but the technology of mounting natural tiles is the same for both ceramic and central plaster. shingles, colors of ceramic tiles are a bit poorer than in ts.p. shingles, this is due to the fact that dyes are added to the cement-sand shingles during manufacture, and dyes are not used in the manufacture of ceramic tiles.However, the tiles of ceramic tiles are more elegant and thin, in contrast to the ce.p. shingles. And as if manufacturers did not assure you that the tile is reliable and durable just like its progenitor is a ceramic tile, they are a little cunning, of course, the central point. shingles are reliable and installation technologies are similar, but here is the service life in favor of ceramic tiles. You can call a specialist to inspect your roof, you will receive recommendations for the upcoming repair or installation of natural tiles.
Bituminous soft roofs
Bituminous deposited (soft)roofingoften found on urban high-rise and industrial buildings.
Overlaid roofs, also called soft roofs, belong to a series of flat roofs.
The service life of bitumen deposited materials up to 5 - 25 years, depending on the modifier combined with bitumen, the quality of bitumen, the thickness of the bitumen, as well as the basis of waterproofing.
Work (installation, fusion waterproofing) are performed using fused high-strength roll materials on a glass cloth (polyester) basis. The material is welded to the surface.roofingusing special gas burners.Before installing or repairing waterproofingsoft roofshould prepare the ground. As the basis for waterproofing can serve as a cement-sand screed, hard mineral wool insulation, CSF slabs, etc.
Be sure to follow the slopes of the roof to the drain funnels or sinks.Special attention should be paid to the vapor barrier, it will significantly increase the life of yourroofingand will allow the roof weatherization to function normally, which will save energy consumption for space heating. When repairing waterproofing carpetsoft roof, a complex of works is being carried out to protect the junction, parapets, build parapet sheet, open bubbles (swelling on the roof), repair or install the screed, lay insulation (if necessary), remove the roof level to the craters and repair the vapor barrier. Of course, the degree of wear of the roof and the complexity of the repair of waterproofing can determine a specialist. Minimal repairs to waterproofing of a soft roof can only include patchwork and blistering, but these works are not subject to warranty, as they are an extremely unreliable and durable solution to the current problem,such repair of waterproofing only provides an opportunity to save money for more or less suitable repair of bitumen waterproofingsoft roof.
Roofs from a professional leaf
Installation of corrugated roofing:
As a roofing material, profiled sheets are most often used at large-scale facilities in industrial and civil construction. Installation of profiled sheet is allowed onpitched roofswith the slope of the slope at least 12-14 degrees. Recently, a corrugated sheet and corrugated flooring with decorative polymer coatings has found its application in individual and low-rise construction (cottages, small shops, gas stations, kiosks).
The technology of installation and repair of a sloping roof from a professional sheet is similar to the technology of laying metal. At the device (installation and repair) of roofs from a gofrolist, it is necessary to take seriously the insulation of the roof, consider draining water from the roof, because Due to the high thermal conductivity of the metal, ice is easily formed on it, which can pose a serious threat to the owners and people passing by the building. Therefore, a snow retention system should be providedbut this system will not save drains from seasonal wear in the winter period, therefore it is recommended to take into account the heating system of drains, it will extend the life of your gutters and pipes and drastically reduce cleaning costsroofingfrom icicles and snow. Sheets with a low wave height are not recommended to be laid onroofingwith a slight bias! Lathing under the profiled sheet on pitched roofs can be both solid and stepping. Gofrolist overlap each other and fasten the sheathing to the bars with the help of slanted screws into the corrugation. At installation of a professional leaf it is obligatory to use self-tapping screws with sealing gaskets.
Repair professional sheet:
Most often, a professional sheet repair is required on the roofs, at which device they neglected the installation technology of the professional sheet and violated the permissible angle of inclination of the roof. Sometimes repair of a professional sheet is required due to the fact that the professional sheet was laid with insufficient overlap or was fastened with incorrect fasteners. If the roof leaks began as a result of improper maintenance of the roof (cleaning snow and ice), then when repairing a damaged profiled sheet, it will be enough to replace the damaged roof sheet.
Advantages of roofs from a professional leaf:
Weather resistance and non-inflammability of the material. Low weight (5-13 kg / m2) Sheets with polymeric coatings are characterized by high durability (up to 30 years). The warranty on the installation of a professional sheet is 3 years.
The disadvantages of the roof of the profiled sheet:
One of the drawbacks of the roof from the profiled sheet, which have small slopes of ramps - frost, you have to take care every winter for the timely removal of icicles, or to install an anti-icing system (heated roofs).
Mastic roof it is also called the bulk roof after curing is an elastic rubber-like material of a given color, which maintains the performance of the coating in the temperature range from -50 ° C to + 120 ° C. Of all the waterproofing materials, mastic waterproofing is the most durable and wear-resistant, these materials are used even when constructing industrial self-leveling floors. Scope of mastic waterproofing materials: Polyurethane mastic (sealant) bulk roof can be used in the repair of old bitumen roofs, as well as in repairfolded roofor metal, in other words, virtually any roof can be repaired by turning it into a bulk roof.It is not recommended to repair pitched roofs with a slope angle exceeding 35-40 degrees using polyurethane mastic.
Features of installation and repair of bulk mastic roof:
Getting Startedmastic roof, you should be aware of the features of the material, you should not start work if the base is wet or wet, you should also refrain from installing the bulk roof, if precipitation is expected. When installing a mastic polyurethane roof, waterproofing carpet, if necessary, can be reinforced with a special mesh.
- A guarantee for a mastic bulk roof 3 years.
- The service life of the bulk roof of 15 years.
- The possibility of repairing the roof without removing the old waterproofing
- The possibility of additional design solutions - the creation of a waterproofing carpet with a pattern, the possibility of choosing the color according to the color (more than 180 colors and shades).
- High adhesion to almost any base in combination with high elasticity with the solidity of the mastic coating reliably protects all joints from leaks for leaks for many years.
- The ability to repair virtually any roof, no matter pitched roof or flat.The absence (or small value in the modifications with the use of solvents) of shrinkable deformations allows you to perform the entire thickness of the coating in one layer.
Polymer roofing and waterproofing mastic cold is designed for the installation and repair of all types of roofing (flat and pitched), as well as for waterproofing and corrosion protection of concrete and metal structures.
Fire-technical characteristics (G2, B3, RP2) mastics allow you to apply it on almost all objects without limitation, including without the installation of a protective gravel surface.
The main modification of the mastic is available in two components:
1 - polymer;
2 - curing;
The hardening component in the factory is painted in a given color, which ensures a uniform and uniform color of the mastic in the required volumes.
The mixing of components in a given ratio is carried out directly on the construction site before use, which ensures a sufficient duration of storage of mastic. The mastic coating is frost-resistant; when tested on a bar with a rounding radius of (5 ± 0.2) mm at a temperature not higher than minus 50 ° C, no cracks form on the sample surface.The mastic coating is color resistant. In order to achieve the required life time (curing process), when preparing mastic, 20-30% of a special solvent is added to it on the construction site (as requested in the kit). The consumer can independently choose a solvent, while it should not contain alcohols, esters, glycols, glycerols and similar products.
As solvents can be used: acetone, white spirit, solvent, etc.
The main advantage of mastic coatings are:
- The simplicity and versatility of the mastic allows you to perform work both manually, using brushes, rollers, spatulas or doctor blades, and completely mechanize all types of work, starting with dispensing components and ending with applying mastic on the surface.
- High elasticity ensures the absence of cracks on the surface of the roof, even when cracking the base.
- The mastic coating is resistant to weathering and aggressive media, including oils, gasolines, alkalis, sea water, etc.
