Among the roofing materials there are many options that have almost the same characteristics. For example, if you take a metal tile and bitumen tile (soft roof), it can be noted that both options are characterized by reliability, durability and an attractive appearance. In addition, the price of these materials is almost the same. All this turns into a deadlock of private developers when they make a choice, which is better: metal tile or soft roof. However, to solve the problem must be made comparative analysis some features of metal tile and soft roof and conclude what characteristics are most suitable for certain conditions Construction.
To begin with, it is worth understanding that they are compared materials.
Metal tile is a profiled sheet having longitudinal and transverse corrugations, as a result of which the semblance of ceramic tiles is created. With visual inspection, even from a short distance it is quite difficult to distinguish metal modules from the piece tile.
The metal tile has a complex structure, which is based on thin steel with a bilateral zinc coating with a thickness of about 20 μm. In addition, both sides have a passivating layer and primer. The finishing layer from the bottom is the protective paint, the upper part is coated with a layer of polymer.
The bituminous tile is produced in the form of a narrow tape having cuts in the form of a rectangle, rhombus or petal. When laying these elements on the roof, a unique pattern is created, characteristic of a specific type of product.
Soft roof is a material with a multi-layer structure. The glass cholester, which is the basis of the material, is coated with a modified or oxidized bitumen. On the facial They apply a stone crumb-granulate, the lower part is covered with a bitumen-polymer adhesive composition, with which the tapes can be glued together without using mastic.
Based on this, we can say that both variants are similar to natural tiles, and the multilayer structure of both materials provides strength and durability.
What kind of result can be obtained if you compare what is better: metal tile or flexible tile on the most significant characteristics.
Metal tile sheets have a fairly large size. Their length is most often 4.5 meters, and in some situations can reach 7.5 meters. The width of the sheet in most cases is 1.12-1.19 meters. Therefore, it suggests that the installation of material alone is almost impossible. In addition, the elongated sheets are very difficult to raise height and fix on rafters.
Bituminous tile In this regard, the more favorable option: the material is produced in the form of a tape up to 1 meter long and a width of 33.7 cm. Therefore, it does not occur when lifting on the roof and performing installation work, even if the work does one person.
When comparing weight, a slightly different result is obtained. The mass of 1 m 2 roofs from metal tile is no more than 5 kg. But the similar area of \u200b\u200bthe soft roof will weigh from 8 to 12 kg.
Thus, the metal tile has more overall dimensions than bituminous tile, but the first version weighs less, therefore, the load on the rafter system will be small.
Choosing metal tile or soft roof, you should know that both compared material are used for laying on the pitched roofs, minimal which is 12-14 degrees.
Soft tile It is considered a more versatile option, as it can be used on the roofs of any form, even with the presence of domes and turrets. An insignificant weight and sizes of material make it possible to cover broken and curved surfaces. In sophisticated places, the tape must be adjusted and it takes the necessary shape. The predominant point of installation of a soft roof in this case can be called the minimum amount of waste, up to 3%.
Metal tile can only fit on the root with straight skates. The presence of fades and additional parts makes the installation of metal tiles very problematic. This is explained by a large number of subsoring, as a result of which up to 30% of waste can be formed. In addition, when cutting material, open edges are formed, which must be painted to prevent the formation of corrosion. This inevitably leads to an increase in the costs associated with the arrangement of the roof.
Thus, answering the question, which tile is better for the roof, we can say that the soft roof is more profitable for the roof, which has a complex shape and structural features.
Regardless of the roofing material, flexible tile or professional flooring, is greater significance has the type of base for it. Installation of metal tile is performed on the crate of boards or bars. The distance between the base elements is chosen depending on the wavelength, in most cases it is 35-40 cm.
Bituminous tile laid on a solid two-layer crate. The first layer is the usual rarefied base, the second is solid, a plywood or oriented chipboard is used for its manufacture.
Thus, for bitumen tiles, a more complex foundation requires large financial costs. Metal tile in this case will cost much cheaper.
The coating of the roof of metal tile does not represent any particular difficulties. Due to the large size of the module, the laying process does not take much time. Simple installation without professional features allows you to perform work even beginners, which in most cases show good results.
Laying the soft roof requires increased attention, as as a result of the perfect roof error can lose their performance features. Consequently, the installation of soft tiles is best to entrust professionals that have appropriate qualifications and experience.
If you compare the labor costs, then here you can observe the following situation: the soft roof is mounted slower, but the bulky sheets of metal tiles lay longer and more difficult.
Raise large metal tile modules is also much more complicated than flexible roof tapes. At least additional labor and special mechanisms or devices in the first case will be necessary. Bituminous tile tapes are quite possible to raise and put one person.
The implementation of assembly work on laying metal tile on a simple scope roof is not difficult, but the presence of even small fuss adds difficulties in this process. At the same time, in some situations, labor costs can be significantly higher than in the case of soft tiles.
Thus, the installation of metal tiles will be faster and easier to one-sided or two-tie roofs, provided that the work is performed by two or more people. Complex, broken and multicate roofs are better covering soft tiles.
One of the disadvantages of metal tiles can be called the creation of an increased noise from the beats of a hail or droplets of the rain. To reduce the level of noise, additional sound insulation is necessary. To do this, you can use insulation with a thickness of more than 15-20 cm with good sound insulation properties. It is very important to perform such actions during the arrangement of an attic residential premises so that the rain droplets bending did not violate the comfort and peace of tenants.
The soft roof in this regard does not cause problems, the use of additional sound insulation under this material is not required. Bituminous tile is perfect for arbors, garages, summer attic and other rooms that do not require thermal insulation.
The roof covered with and metal tile, and soft tiles, has the same attractive appearance.
Metal tile is some similarity of the classical ceramic tile, so it looks more natural. At the same time there are a variety of profiles that differ in size and shape of the wave, the color solution is presented by hundreds of options. The following profiles are very popular: Joker, Cascade, Monterrey and Super Monterrey. Consequently, the metal tile can pick up any shade, for any architectural ensemble and the most exquisite taste.
The ability to design a soft roof is also varied, with the help of this material you can revive any idea. The appearance of such a coating is determined by the form of cutting bituminous tape. It may be rhombus, hexagon, rectangle, oval and much more.
In terms of coloring, the soft roof is not inferior to its competitor: the color solution is wide enough. And the tile petals can be painted in one color, and can be used different colors And shades.
One of the advantages of the soft roof is a hidden fastener. Ribbons are fixed on the crate by the self-adhesive layer on the inner surface and small fasteners, which are easily overlapped by the upper number of the material. For fastening, metal tiles use special self-tapping screws, which are painted in tone with the material. But even this condition does not allow fully hidden the location of the fastener.
On the duration of the operational period, the coating for the roof is affected by the degree of its wear resistance. In the case of metal tile, this factor depends on the type of polymer coating and zinc content. The average life of the metal tile indicated by the manufacturer is from 20 years to half a century.
Soft tile from bitumen can be perfectly operated for 30-50 years. For the service life of soft tiles affects the quality of the coating used, its thickness and type of base.
Thus, if you compare metal tile and soft roof, both options have approximately the same service life, subject to the choice of high-quality material and compliance with the installation technology.
For many, it seems to be a question that is cheaper: metal tile or flexible tile. When comparing prices for directly the material and additional costs of its installation, the following situation is described: soft tiles, like material, more expensive metal tiles. For a soft roof, a continuous foundation is needed that inevitably leads to an increase in costs. In addition, the bitumen tile is in most cases fit by professionals, and the process itself takes a significant amount of time.
Based on this, we can say that the use of metal tile as roofing material is a more profitable option from the financial side.
Comparison of metal tile and soft roof shows that each material has its advantages and disadvantages. Therefore, the choice should be done in accordance with the specific conditions.
In fact, a soft roof is an improved rubberoid. As all recently in construction (for example, the same) he received several new layers. Prices different types Products are distinguished insignificantly, so such a roof can be built practically on with different architectural features. But wear-resistant characteristics went far away from their ancestor - simple rubberoid. In this review, we consider species of the soft roof, the pros and cons of the use of this material, as well as study the range of products, which is presented in the construction market of our country.
As we have already noticed earlier, the basis of the building material is all the same ruler. It is applied to the decades for the roofs, has high wear-resistant characteristics. Thanks to this quality, manufacturers of modern roofing materials and paid attention to it. However, durability is far from everything, one of the main deficiencies of the runneroid its low tensile strength. Over time, the material simply crumbled. One very important change appeared in modern variations in the soft roof - the rubberoid received a very solid foundation - glass cholester.
The glass cholester consists of fiberglass filaments and organic resins. There are several class strength classes. This material was taken as a reinforcing coating.
The Bitumen structure itself has changed. It includes more improved additives that increased its resistance to negative environmental factors: low temperatures, overheating, high humidity, and so on.
Architects immediately understood, an improved coating can not just throw layers, rolling rolls, but also to create new, completely unique materials for finishing. One of the embodiments of the idea was soft tile. A variety of types, shapes, shades allow you to create real architectural masterpieces. Look at the photo, which unexpected and unusual options for using soft tiles can be.
If the runneroid was used for the most part for, modern flexible rolls are a full-fledged construction material. It carries many features. Completed using modern polymers it is perfect, can act as finish finish or preliminary layer.
Tip! You will find on sale all sorts of mastic, as well as polymer membranes and bitumen tiles. Rolled coating is more convenient to lay on a flat roof, and the bitumen tile is most often used on roofing with a complex relief.
As we have already noticed above, a soft tile is a complex multilayer product. The upper layer most often consists of a protective coating, used mainly spraying from basalt and shale crumbs.
The layer of sprinkling is fixed already on the very layer of SBS-bitumen. Sometimes natural oxidized bitumen can be used. This material does not differ in durability, and this option is better not to buy. Since its characteristics will give way to synthetic. The latter stretches well, does not break when tension and has high wear-resistant characteristics. All of these layers are attached to a well-known one of the glass cholester. The lower layer has a special sticky impregnation, which is protected by a special film.
Based on the features and quality of the coating of each of these layers, the types of products can be distinguished, which in turn have different costs.
Soft tile can have a different shape. The most common variations of "petals": oval, hexagon, brick, rectangle, rhombus. There are more non-standard species Farmers.
There are variations not only forms, but also shades. color Gamma.. Their great set. The most popular is red-red, brick or brown shades. Whole tile monochrome. The cost in a state for September 2018 is approximately 235 rubles per 1 m².
bituminous tile
Multicolor tile will cost somewhat more expensive. Most often these are foreign samples from the USA and Finland. The cost of a multicolor option is from 340 rubles per 1 m².
And finally, an ultramodern option - a tile with a 3D effect. This design is used for the form "Dranca". The price of a square meter is from 430 rubles per 1 m².
Among the types and options for the implementation of the new technology, the soft roofs of TechnoNIKOL Schinglas are most often celebrated for high quality. The cost of such tiles from 250 rubles per 1 m².
bituminous Tile Technonikol Shinglas
But the soft roofing material for the roof produced in rolls will cost almost several times cheaper than bituminous tile. Its average price is from 180 rubles per ten meter roll. Low cost makes this material leader among budget options.
Separate several variants of the rolled roof depending on the basics used:
roofing cardboard
uniflex
Olefin, rubber and polyvinyl chloride - these materials are used to create a solid membrane base. Each manufacturer tries to profitably improve its composition to provide even higher quality products and increase its life.
Views of roofing membranes:
The only thing that may cause difficulties is to install joints. It must be done with glue. This method is not as reliable as welding. The cost of such a membrane is 490 rubles per m².
ePDM Membrane
TPO membranes
PVC membrane
Products of the brand Tekhnonikol have long been loved by the Russian buyer for fairly democratic roofing material prices and high quality products. The material is produced by different types and options for using reinforcing layers and coatings.
Consider the main ones first in the budget segment:
glassizol
Products of the average price category:
linorm.
bicroelast
The average value of m² for these materials from 500 rubles.
Premium-class materials:
uniflex
Soft roof, like any other building material has its advantages and disadvantages that may affect the decision to purchase.
Among the advantages can be allocated:
Disadvantages:
This can lead to the reinforcement of OSB sheets, in winter the accumulated moisture can cut the tightness of the coating under pressure and squeeze the bitumen tile.
Pay attention to the fact that the branches of the trees adjacent to the building can not touch the tiles. Pets can also spoil the tightness of the masonry.
Installation of a soft roof will not cause any difficulty, subject to the styling technology.
We offer to study in detail all stages of work for laying soft tiles at home with complex geometry.
The soft roof is popular at no less than solid and solid structures. But it is represented by a large number of types, each of which has features when installing and operating. Only understanding in all these intricacies, you can take the right solution when choosing a material.
The device of a soft roof is quite simple - it is a tile and a glass tissue, soaked in a modified bitumen. To make the coating strength, it is complemented by stone crumb. The product has a curly edge, it is necessary to lay it on the brace of the roof. Modern producers have mastered the production of soft roofs of various geometric configuration - these are ovals, and semi-rapidness, and pentagons. More familiar rectangular blocks can also be found easily.
Under the soft roof, laid on a relatively color (up to 18 degrees), the surface of the skate, the waterproofing layer must be created only in the least protected places.
These include:
plots next to pipes;
If the total steepness is less than 5 degrees, liquid waterproofing materials can be used.
If it is more, only solid coatings are allowed. With the exception of atypical structural solutions, the lading of waterproofing should be carried out in the intervals between the rafters and the crate. Laying is conducted from the cornice to the skate. Allowed the sagging within 2 cm, because it improves ventilation inside.
Parosolation for a soft roof is almost mandatoryBecause only this measure allows you to prevent the destruction of the crate and the accumulation of condensate. In the case of a warmed room, the vapor insulation material is attached from the inside the attic directly to the rafter feet. Then, an attic surface is created on top of the membrane (from plywood, boards or drywall). From the outer side over vaporizolation, a material that provides insulation is constructed. In old or reconstructed homes, you can sometimes meet a single-layer display of the insulation, but such a scheme is considered obsolete and not effective.
When choosing a modern two-layer variant, the material with the highest thermal stability is placed at the bottom, the thickness of its layer varies from 70 to 170 mm.
The advantage of such a device is that heat-stash has a slight mass. But if initially in the building is equipped with single-layer thermal insulation, then during the repair or reconstruction of this particular scheme it is better to stick again. Otherwise, you will need to drastically process the entire scheme. roofing cake, Including to redo the substrate.
His specificity has lightning protection of a soft roof. In most cases, such roofs are equipped with passive protection means. But the general rule does not always work, and appreciate its applicability properly only prepared by the specialist. Consultation with it will avoid multiple mistakes and significant material losses, and sometimes victims. The rods of active receivers should be raised to raise at least 2 m above the roof, and still thinking the roof design should be thought of how the spiers will be fixed.
The grid can be mounted only above the coating, because the internal location increases the risk of fire. Typical mesh cross section - 6 mm. Autonomous structures are equipped with duplex roofs, each of them is separated. The discharge should be distributed over two ways, the flow of current movement for each of them is trying to make the minimum. Clamps can not be brought around windows and doors.
Any construction I. finishing material has a number of positive and negative sides; It fully applies to the soft roof. It serves quite long. No other coating can work out more than 70 years; It is much higher than that of the roofs of the corrugated. Remedy operational defects are relatively simple: you only need to remove single damaged tiles.
In addition, soft roofs:
resistant to bad weather conditions;
immune to the action of microflora;
throughout the operational period, it looks very good and remains strong;
can be mounted even without assistance;
mostly suppresses the noise arising from a strong rain and even hare.
As for the shortcomings, flexible roof It has one weak place - it lights easily. And for this reason, the material is not suitable for buildings, where the risk of ignition is very large. If there is no such danger, the fee for the soft roof and its installation is fully justified by its characteristics. During operation, the amount of waste is relatively small, and can be used without excessive effort to build geometrically complex configurations.
Ultraviolet rays are not scary to the created coating, but it is weakly kept heat, and the base should be mounted as an inseparable web.
The first step in the laying is preparing essential materials and tools. In accordance with the requirements of the technology, you need to have a very strong base that will not be fed under load. At the next stage, the ventilation must be equipped to cope with high humidity and reduce ice accumulation in winter. After graduating from the preparation of ventilation, the specialists are taken for creating a gasket layer, which should be located throughout the perimeter. The material should be protected from precipitation, for this purpose the cornese strips are used (sometimes they are called drippers).
Fellow designs are equipped with frontal planksMounting them lead with an overlap 20 mm. Riding nails relies with a step of 100 mm. Marked where the chimney pipe will be withdrawn. When the installation of the planks will finish, put the rover of the endand to strengthen the protection against moisture; This carpet has the same coloring as the roof itself. The cornice tile can be replaced by an ordinary, it will help slightly reduce installation costs.
An ordinary tile is put, moving from the middle of the roofing sink in both directions. It is possible to remove the protective shell from the shingles exclusively before the installation itself, since it only allows you to fold the material in packs. Fuck the tile is assumed to nails (4 pieces are used for one shings), but when the roof is biased more than 45 degrees already need 6 pieces.
The first row is removed from the ends of the eaves of the cornice by 10-15 mm, the second is put in the same way, only covering the petals of the neck cuts of the first tier.
The edges are cut along the edge line and sample, leaving a layer of 100 mm. Cut follows on the subplated plywood, then the lower layer will not suffer. The skate tile put, starting with the installation of the stage, then the blocks are putting the brand 50 mm or so. Farmers need to be cut through perforation lines - it turns out the skate coating. Minor yields through the roof are organized using rubber insulation, but the heating pipes are output differently.
The perimeter of the intersection of the pipe and the roof is covered with a triangular rail. Then the gasket carpet is mounted, pre-lubricated with glue. The pipe is found to isolate (with a closing of 0.35 meters and 0.25 meters of the slope). When this is done, you only need to attach adjacent strips around the perimeter of pipes, mount steel apron and seal the joints with a silicone-based mixture.
On a flat roof, they are put in the main rollers of the European sample rubberoid. It is sometimes used on a scope roof with a slight bias. Rolled the roll, you need to align the folds, stretch the material. It is heated by one of the sides, waiting for the melting of a special indicator. Immediately after that it is required to glue the side to the substrate and roll off the roll to the next point of attachment.
Reference Ruberoid is required with a false 50 mm, control it helps the orienting strip.
But overheating of the material can deprive its ability to adhere to the surface. Qualitatively performed work is expressed in the fact that the surface does not have voids, dark plots and so on. Only strictly observing all the requirements for the requirements, you can guarantee long-term roofing service. The minimum roof inclination angle on which any kind of soft tiles can be mounted is 12 degrees.
Principal reasons why mount soft roof in the cold season, no.
Attaching the soft roof is possibly two main ways.Most often use self-adhesive bituminous layer, occupying the lower side of the tiles. When the protective film was removed, the bitumen becomes soft and glued to the substrate. But such a material can only be used at a temperature not lower than +5 degrees and low air humidity. If these conditions are not observed, you will need enhanced heated by special installations, because the cost of work will immediately increase.
An alternative is the use of roofing nails with an outer zinc layer and wide hats. This technique allows not to think about weather conditions - If only they allowed to safely perform work on the roof. But mounted errors can lead to the destruction of the design and the occurrence of leaks. Snip prescribes to mount a soft roof on nails only under slopes of less than 20 degrees, and the skates are tilted at angles from 15 to 25 degrees. The higher this value, the more actively water is dried, therefore the risk of leakage is reduced.
To cover the roof in the winter rubberoid, you will have to use special heating.
Even with this condition, the roofing material is supposed to withstand several hours in the warm room. From the inside, all the shings are equipped with a self-adhesive bitumen layer, which holds the part of the design among themselves. If you only score nails, but do not warm up the material as it should, it will simply disintegrate into part. ABOUT beautiful video And the reliability in such a situation does not have to speak.
The roofing carpet is superimposed on the side of the sumps and any end of 40 cm in width.Attachment is made using large roofing nails, they are driven by 0.2 m from each other. The covering of the cornisses is provided by necessarily and steel straps. For the ends, it is designed to look at the planks - frontal execution. The processed surface must be very clean and dry; When flooring a bituminous material, you need to use blocks from various packages to avoid uneven shades distribution.
The horse is fixed with roofing nails long.
If it is long, you can put several elements of the jack. From above, a special skating tile is mounted, with which the protective films remove. The processed area is fixed with nail pairs (left and right). We need to lay a soft roof at the counter direction with respect to dominant winds, a raid of fragments is 30-50 mm.
On the pitched roof, the material is applied and glued first at the lowest points, then rising upstairs on the skates. The maximum allowable mounting bias is 25 degrees. If it exceeds 15 degrees, you need to lay a soft roof along the flow of precipitation (at right angles to the harrow feet). But such arrangement is quite difficult, and therefore only single enthusiasts are resorted to it. The monolithic doom is pre-created.
To get it you need to use:
oriented plates;
plywood sheets with increased moisture protection;
boards with humidity maximum 20%.
The soft roof is not something uniform, it is a whole selection of roofing materials combined only with elasticity. The differences between them are due to the chemical composition, commodity view and installation method. Rolled variety is various rubberoid varieties, only It also includes the latest types of membrane products. It is possible to put the roll relatively quickly, but its appearance is difficult to call the attractive for people. Consumption per 1 square. M. rolled roof (together with the lining) make up at least 500 rubles; It is necessary to apply them only at an angle of inclination from 12 degrees.
Ruberoid is very checked, because it is made of dense cardboard, but such a coating relatively badly tolerates temperature differences.
Fiberglass is easier to experience them, the fee for it is justified by increased quality and a long period of use.
His advantages have a bitumen tile, called a shingle (or otherwise). These are tiles whose length is 1 m, and the width varies from 0.3 to 0.45 m, the laying is carried out. Time to work is needed more than when using membrane solutions, but the self-adhesive layer helps to abandon enhanced warm-up. The cost of the design is noticeably higher, especially taking into account funds spent on the processing of the base. They can only be a monolithic label from moisture protected by the chipboard.
The flexible tile device according to the standards of SNiP includes:
fiberglass;
a special modification of bitumen;
strengthened subfocation.
Fiberglass - durable and chaotic distributed inside the thread. Thanks to them, protection against high temperatures, cracking is excluded. If you buy a premium expensive coating, it will be enhanced by a polyester, further increasing the practical quality of the material. In fiberglass, the production absorbs bitumen with the inclusion of polyester resins and synthetic rubber. Such impregnation allows the soft roof to not get intoxicate, suppresses the occurrence of mold fungi.
The enhancing material (mineral granules of various tones) makes the surface of the rough. In most cases, crumbs are used from marble, granite or basalt. Mastic (bulk) roof is built of expensive materials, but in general, the work on installing it is relatively cheap. Roofing work will be partially mechanized. The exception of seams allows to reduce the design vulnerability to leaks. As for difficulties, it is extremely difficult to form homogeneous and uniform layers, as well as unacceptably lead work at the slightest probability of precipitation.
The Finnish KatePal roof has excellent practical characteristics, with its help you can embody quite a lot of designer designs.
This product is characterized by a specific type of gluing, it is very durable and well kept warm. Due to flexibility, it will be easy for a curvilinear surface, complex curly elements of the roof. The thoughtful design allows you to perfectly stick blocks with each other, guaranteeing the sealing of the coating.
As a base, you can apply:
plywood sheet resistant to humidity;
plotted board;
edged board.
To obtain a lining layer on the ends, endows, skating and eaves, it is recommended to apply a special brand development. The formation of soles is made from steel sheets stacked with displacement. Start working, moving from the middle of the swell. Before sticking, all elements must be cleaned of protecting film. Strengthen the mount can be at the expense of nails. By the installation of skates, put the last link, using special skate tiles.
Colors and texture soft roofs are quite varied, differences between them are manifested in the texture. There are options that imitate the appearance of natural tiles and even specially aged performance, as if the surface of the ripped moss or lichen. If solutions are applied based on mastic, various pigments add to it. Due to this, you can get need effect. IMPORTANT: Endament carpet or galvanized metal must have the same coloring as the soft roof itself. If this is not the case, the desonant dissonance will exclude the receipt of an attractive appearance.
Bituminous and bitumen-polymer variety of rolls are applied to four different ways. Attaching hot mastic consisting of bitumen (by itself or in a mixture with rubber) is tested by time. The disadvantage is the need to mechanize the whole process, attract a whole brigade of repairmen. You can also glue a soft root on cold mastic, such as Vishera; But this approach is suitable only for materials, the thickness of which does not exceed 0.28 cm. Mastics, in this case, serve to lubricate not the substrate, but an attached coating.
An embodiment with a cold gauge means dissolving bitumen from the inside of the material.
The lower surfaces of the sheets are processed by kerosene or White Spirit, The same substance is applied to the primer-trimmed base. Attaching the bands is made with a side adhesion of 100-120 mm, on the ends, they are fixed with 150 mm raid. You can perform work alone, but for this you will have to work very quickly. You need to adjust the rolled material with the clutch of the molten or heated back layers of materials treated with bitumen mastic, and with the help of gas burners.
The disadvantages of this approach are obvious:
partial burnout of the roof;
weakening of wear resistance of the coating;
high risk of fire.
Much better and safer to work with the help of infrared heating systems; This work is performed by the smaller two people. One performer spins the roll and smelves the surface of the sheet, and the other with the help of a silicone roller presses it to the surface. Self-adhesive materials can be attached without additional effort only when working with fine insulation. Its thickness does not exceed 0.12 cm, the decorative properties of such a coating are zero. Yes, and the durability of the material is too small, it flashes quickly.
The quality of the soft roof is defined both the technology for the preparation of bases and the quality of fixing blocks. Manufacturers have made every effort to improve the technical parameters of the coating, and continue to improve their products. Once rolled materials could only protect the roof from the blotch, but now they are attractive in the design plan. The flexible shell of the roof of houses is now supplied in a convenient packaging, and a slight width makes it possible to unwind the roll in an arbitrary direction. Engineers were able to increase the resistance of the discontinuity, and lay out modern rolls with a slight equipment tool and auxiliary fixtures.
The roofing material of the last generation allows you to close by 100% of the foundation of any configuration, even with a very complex geometry.
There is no need to leave the house, because the noise when working is very weak, and there is no danger to health. The roof pie over a warm attic can not be limited to a combination of a rigid lining and a soft outer layer.
In addition to them, you will need:
waterproofing membrane (sheltered above rafters);
thermal insulation using basalt or mineral wool;
vaporizoation;
carefully thought out doom.
The soft roof due to the rough layer makes it possible to abandon the installation of snowmates. Downstairs should be made lining pie if the roof is cooler 20 degrees. The lining is mounted only at the most vulnerable points. It must be necessary on the junctions and gutters, at the junctions between the skates and walls. A rough shell of a number of materials is delayed not only snow, but also dirt. Therefore, if it is planned to use a roof for leisure and generally often be on it, it is better to use smooth coatings.
The soft tile is mounted differently than the metal tile, it does not fit the drying of the bar for it, since the material does not have a clear fixation. If the board is put down at the bottom, it is recommended to purchase it in the winter, and to apply in the warm season. Then the level of humidity will be completely optimal. The best options for boards - with a width of about 100 mm, and all elements must have approximately the same value. The underlined rug next to the skates must have a length of 250 mm, and on the sides of the end, this distance is 0.5 m.
According to the scheme it is required to equip ventilating system; If it works not effectively, the rafters will quickly collapse with condensate, ice and rot. It is necessarily necessary to equip the product and air outputs under the cornice. The gap from the tiles to the base of the roof also plays a role in the ventilation of the inner parts of the roof. This technique also solves the problem of outward water vapor. Rolled materials are fixed with cold and hot mastic.
The cold mixture is needed for the inner segments of the roof, outside work exclusively with hot substances.
If you use bitumen, it is required to complement fillers with dust-like (lime, plaster or ash) or fibrous structure. The best mastic among professionals are those that contain polymers. Preparation of cold compounds from undergraduate components is not difficult. Take two working tanks, one of which is filled with bitumen, and the other - solarium and filler (in proportion 2: 2: 1).
Reservoirs are heated to 180 degrees; Drying bitumen, you need to mix cooked substances. Getting hot mastic is achieved somewhat differently: the bitumen heats up to 200 degrees and gradually, with caution, add filler to it. In the process of stirring, the substance should not be cooled to more than 160 degrees. To evaluate the quality of the resulting composition, it should be cooled to 60 degrees, and then apply to the skate with an angle of 45 degrees. A decent mastic should not drain the surface itself, and when it freezes, forms smooth surface without a single crack.
The base of the design is made of wood, which is impregnated with a mixture of diembered with bitumen. Then the surface is smeared with mastic, and only after that you can fit the parchment and rubberoid. The step of the crate under the roof of Ontulin, the slope of which exceeds 12 degrees, should be small; The exact value is determined for each specific underlying material. A steam-diffusing film under a soft roof is made of polyethylene and polypropylene, it is reinforced by a grid or cloth. Microscopic perforation allows you to protect the coating from moisture, and if it is not, the film will skip steam.
Installation of ventilation under the polymer roof is quite difficult - you will need aerators, flugars and produced. After all, the overlap is irpertable for a pair of membranes does not allow water to leave the underpants space. Aerators need to be put even in the case when a completely new roof is created, covered with liquid rubber. Small flugarks put every 60 kV. m, and large - for every 100 square meters. m underpressure. The gap between close aerators should not exceed 12 m.
The ventilation unit is most often placed where the insulation slabs are joined. But when used for insulation, PPU is simply no, so it is better to consult with experienced engineers. During the repair of the old roof the best solution It turns out the installation of ventilation points where large bubbles and bloating are detected - they are shown to the location of the vapor. Fastening the aerators to the roofs and canopies made of soft roofs should be performed on the self-tapping screws exhibited in five or six places throughout the perimeter of the structure.
The necessary points indicate the technical regulations must necessarily have an internal reinforcing layer.
Dismantling of the roof from bitumen - it's not too complicated, but requiring certain accuracy and care. If you need to perform work when overhaul Or in the zone of tight building, it is better to turn to professionals. Manipulation do it yourself cannot be quite safe and effective. But if it was still decided to do this, it will be necessary for special tools - strokesis, roofing ax. It is necessary to work only with dry weather and at a temperature of a maximum of 20 degrees, because with a significant heating bitumen melts and complicates the analysis of the design.
Of course, before dismantling all the decorative elements, electrical and antenna equipment, lightning tracks must be removed. Problems often arise with chimneys and ventilation, so in the presence of such structures try to independently repair the roof is not worth it. Adjusting to the wall structures of the soft roof is achieved through various technical solutions. Insufficiently smooth or partially destroyed brick walls for a more dense convergence are covered with plaster. To ensure the waterproofing of the joints can be possible only after the final drying of the mastic.
Flat roofing It should be connected to the reinforced concrete wall only in the case when that even has no cracks or chips. Noticing such defects, they are eliminated using any suitable sealant. The slightest ledge for the contour is immediately removed. Communicable processing primems. Nails for the soft roof must be special, they are used if the base is made of wood or from plywood sheets.
Experienced roofers necessarily have the stock of nails of various lengths and thickness so that you can cope with the most different problems.
The approach to the repair of the coating depends on what its direct appearance. With minor (up to 40% of the area) deformations, it is permissible to limit the replacement of single affected areas. In more serious cases, do not do without the removal of all coverage and laying instead of his new layer. Areas where the marks will be laid, it should be cleaned of dust and degrease.
The area of \u200b\u200beach applied patch should be 30% and more exceed the detected defect itself.If the total area of \u200b\u200bthe roof is small, sometimes it turns out just put a new layer without removing the old one. But it is necessary to think thoroughly, it will be safe, because it is practically impossible to control the condition of the internal layers. With major repairs it is desirable to examine everything drainage pipes, Parapets, eaves and frontones, other elements, and if necessary - to change them immediately. To extend the service life of a soft roof and reduce the need for repair, you need to properly operate the coating.
Regular inspection is very important: it is made in spring and autumn, when the air temperature is +5 degrees. Large garbage fragments need to be collected manually, and small contaminants are removed with soft brooms. We necessarily purify the drains, gutters, remove the mosses and lichen, the problem areas are disinfected. If the layer of snow is formed in winter, it is carefully removed from rubber scrapers or plastics, trying not to touch the coating itself. Of course, at the same time, precautions are strictly observed when working at height.
