Step-by-step instructions for roofing roofing material

Today, roofing felt is available in two versions. Ordinary, which is known for a long time, and with stone crumbs. When adjusting the roof cover, both are used. A "simple" ruberoid is covered with the first layer, and the material with crumb is topped. It should be taken into account that it is necessary to coat the roof with roofing material in dry weather.

Preparatory activities

Preparation of the roof surface

The requirement is uniform - it must be flat, clean and dry. If the roof is only being built, then there is no problem with it. And if it overlaps, you must completely remove all the remains of the old roof. Particular attention should be paid to this, if it was previously covered with a roofing felt. Very often, such work uses resin. It simply glued strips of ruberoid.

After a while, under the influence of environmental conditions( temperature drops, direct sunlight, and so on), the resin crackles. If it is left, water will accumulate in the cracks after a while. If the floor is a reinforced concrete slab, the roof must be cleaned to the concrete. If there is a coupler, everything is removed right up to it. It is necessary in this case to check the quality of the remaining screed and, if necessary, to update.




A special mastic is applied to a clean and dry roof. It is of different composition, so you need to clarify on the label the time of its "grasp" and the conditions of application( air temperature, humidity).

Strip preparation and some laying rules

As already mentioned, the first layer is an ordinary roofing material, without stone crumbs. All strips are laid down according to one rule - horizontally and from the bottom up. To prevent the ingress of water under the roofing material, they are stacked with some overlap. When laying the second layer, it must be taken into account that to improve the insulation of the roof, the seams of the lower and upper layers should not coincide. Therefore, the second layer is superposed with an offset relative to the first.

For ease of laying strips produce so. First, the roll is unwound and the strips of the required length are cut off. In doing so, you need to make a small allowance. After this, the strip that needs to be applied is rolled back into a flat, without protrusions, "tube".After applying one edge to the roof will only roll out the prepared strip.

Laying of ruberoid

Work together. A sheet of roofing felt on the roof is heated by a gas burner. It is necessary to warm up until the top film has gone white and burns. It says that both the material and the mastic under it are "ready" for gluing. The strip is glued in parts. While one person presses the heated part to the roof and thoroughly smoothes to qualitative adhesion, the second heats the next section. And so - the band after the band.

 It is necessary to monitor the heating process. If the heat is too much, the ruberoid may melt. Therefore, before you start the basic work, it is recommended to "work out" a little on small pieces.

With a very flat surface( smooth plate), it is better to pass the strip with a hand roller. If there are irregularities, then it is necessary to manually achieve a quality fit of the roofing material to the roof surface. This is usually done with a rag.

It should be borne in mind that you can proceed to work with the second layer only after the final freezing of the first one.
