Soft roofing is one of the most popular typesprotection of roofs from adverse environmental factors. There are several of its varieties, and consequently, several styling techniques. About how exactly the installation of a soft roof is done in this or that case, we'll talk further in the article. This material can be classified into three main varieties.
Rolled soft roofing
It is fixed by bitumen mastic.As an example of this type of coating, an ordinary roofing felt can be cited. The advantages of this type of coating include, first of all, low weight and ease of installation. To the disadvantages - a large number of joints.
Soft tiles
It is the same ruberoid, but cut into pieces withpetals, imitating real shingles. Possessing all the advantages and disadvantages of an ordinary roofing felt, but at the same time it has a beautiful appearance, as it can be painted in any colors with an imitation of shadows from real shingles.
Welded soft roof
The welded roof is also sold in rolls, butis fixed by melting the mastic already applied to the material when heated with a gas burner. The advantages of this type of soft roof include light weight, strength and elasticity, as well as resistance to UV rays and significant temperature fluctuations. Installation of a soft roof (photo of the process can be seen on the page below) is slightly more difficult to implement than gluing of roofing material. This can be attributed to some minuses of the material.
Sprayed and painted
Paint and sprayed soft roof - liquidWaterproof substance, which, when applied to the roof, forms a thick flexible protective layer. Unconditional advantage of this kind of soft roof is elasticity and strength. However, because of the need to use expensive equipment, such roofs are more often arranged on the roofs of industrial objects, as well as multi-apartment city houses.
Installation of a roll roofing
First, let's look at how to install a softroofing of the roll variety. Do experts recommend this work with an assistant. The ruberoid is preliminarily cut and leaves the strip to lie until the morning. This is necessary in order to facilitate their installation on the roof. The lining under any soft roofing material should be continuous. You can make it, for example, from plywood. The order of mounting the roofing material is as follows:
- The roof is smeared with bitumen mastic on gentle slopes - stripes, on steep - solid.
- To the oversaturated area, a sheet of roofing felt is pressed and flattened (like wallpaper).
- They are raised and additionally smeared to a depth of about 15 cm of the edge of the sheet.
- The next strip is pasted.
Thus, a sufficiently reliablesoft roof. The installation instructions for this version will be incomplete, if not add that one layer of ruberoid from leaks certainly will not save. The fact is that this material is very weak at the break and is easily damaged. The number of layers depends on the angle of inclination of roof rajids. For example, on a shallow roof (at 15about) there are four of them.The lower the slopes, the more overlapping between sheets in the horizontal direction. For a slope of 15 degrees, it should be at least 12 cm. A roofing felt of two varieties is produced - without sprinkling and with sprinkling. The first type is used for gluing intermediate layers, the second type is used for pasting the intermediate layers.
After installing the roof of a soft roofwill be made, carry out a small test for the strength of the fastening. For this, the material is just trying to tear it from the crate somewhere in the corner. If he holds fast, it means that everything is done right.
Installation of soft tiles
Now let's see how the tiled soft roof is mounted. The installation technology in this case is as follows:
- Pre-roofing is covered by a specialwaterproofing membrane, complete with tiles. Fasten it also on the roofing nails strips in the horizontal direction. In this case, the top of each sheet is fixed with roofing nails with a step of 40 cm at the top edge and 10 cm at the bottom.
- After all the roof has been covered, a strip of the same material in the vertical direction is covered with valleys. It is also fastened to roofing nails with a step of 20 cm on both sides.
- At the next stage, the installation of the corniceand end plates made of metal, which are also usually supplied in the kit. They are made of not too thick material and can be fixed to the same nails. Fixation is made with a step of 10 cm "snake".
- Then the carpet is spread. This element always has the same color as the roofing soft tile itself. Fix it over the waterproofing strip on the nails in steps of 10 cm.
- Installation of soft roofs continue installationcornice tape. It is made of the same material as the carpet. Mount it on the nails over the cornice with an indentation from the edge of two centimeters. Preliminary, the protective film is removed from the wrong side.
- The next step - the actual installation of a soft roof -shingles. Use strips with petals you need at once from several packages (4-6). This is necessary to align the color. With each strip remove the protective film and press it with an adhesive layer to the surface of the roof.
- Further, additional fixation with roofing nails is performed one at a time over each notch and at the same level along the edges.
- Each next row is mounted in such a way that the petals of the shingles are aligned with the cutouts of the bands of the previous row.
- Installation of tiles begin from the middle of the ramp, moving to the edges. At the ends, the excess part is cut off and the edge is glued to the waterproofing carpet with bituminous mastic.
- Similarly, glue the tiles to the endow carpet, cutting them through a piece of plywood and leaving an open part of the carpet to 15 cm on both sides of the axis of the valley.
Installation of fusion roofing
Наплавляемая кровля также поставляется в рулонах.Its difference from ruberoid is that bitumen mastic has already been applied to the wrong side of the strips. Most often, glass roofing is used to cover the roofs. Installation of a soft roof of this type is usually performed by three people. This operation consists of the following steps:
- The lining is uniformly primed with a layer of bitumen, diluted with gasoline.
- Laying of sheets is carried out vertically from top to bottom. First, the uppermost edge of the strip at the ridge is glued. It is heated with a torch and pressed against the crate.
- Then roll roll again (bitumen layer out).
- One man clings it with a hook, gradually rolling out.
- The second person, as far as rolling, heats the upper bituminous layer with a burner. The latter begins to melt and forms a liquid adhesive roller between the surface of the roof and the roll.
- Next proceed to pasting the next. The overlap between adjacent should be 15 cm.
So they cover the whole roof.As with any other soft roofing material, the protection will only be effective when gluing several layers. In the intermediate, the deposited material can be located across the roof. That's how the tiled soft roof is fastened. Technology, as you can see, is not particularly complicated.
Types of sprayed roofing material
As a waterproofing coating in thisA mixture that solidifies in air and forms a strong protective film of different thickness is usually used in this case. Only three of its varieties are available:
- One-component. It is sprayed on the surface with high-pressure equipment.
- Two-component. In the process of application, the polymer-bitumen composition and the hardener are mixed. Pressurized into the atomizer and applied with a layer of the required thickness.
- Bitumen-polymer composition. It is applied to the surface with a spatula or roller. In private housing construction, this variety is most often used, since it does not require the use of expensive equipment.
How to apply to the roof bitumen-polymer composition
Next, we will examine how the bituminous soft roof is assembled. Installation instructions:
- Old roof is removed from the roof.
- The surface is cleaned of dirt.
- Brush out the primer coat, which is necessary to increase the adhesive properties of the surface.
- The roof is coated with bitumen-polymer mastic also using a brush or roller.
In order for the protective layer to be as reliable as possible, the roof is coated with several layers. The topmost one usually wakes up for greater reliability in coarse sifted sand.
How much will the roof protection cost a soft roof
Thus, we have figured out how to mountsoft roof. The technology of mounting this material is elementary, and therefore the installation can easily be performed independently. Next, let's look at how much this protection for the roof can do. The price depends primarily on the type of material used, as well as, of course, the number of sprayed or glued layers. However, in general, such roofs are somewhat cheaper than others, made from other materials.
For example, a roll of ruberoid in 15 meters costs about 200 rubles (for 2014). The width of the standard sample is one meter. Therefore, 1 m2 costs about 13 rubles. Accordingly, a square meter of the roof of its three layers is 40 rubles (excluding mastic). Square meter stekloizola costs about 30-50 rubles. Therefore, for 1 m2 in three layers will have to pay 100-150 rubles. Polymer mastic on a bitumen basis costs about 900 rubles per 10 kg. Its consumption per 1 m2 - 1 kg. That is, one square meter in one layer will cost 90 rubles.
These are the most budget options.The cost of installing a soft roof can be higher. In that case, if the work will not be done independently, of course, you will also have to pay hired specialists. In this case, roofing will cost even more. For example, two layers will cost at least 300 rubles.
Как видите, мягкая кровля – материал достаточно reliable and not particularly difficult to install. If desired, you can make an independent installation of a soft roof. The price for it, as you can see, is democratic.
