Step by step instructions to cover the roof with roofing material

Today roofing comes in two versions.Plain, which is known for a long time, and with a stone crumb.At arrangement of the roof covering is applied and the one and the other."Simple" roofing felt is laid the first layer, and a material with grit - top.Take into account that the roof should be covered with roofing material in dry weather.

Preparations

Prepare the roof surface

single requirement - it should be smooth, clean and dry.If the roof is only being built, then this is no problem.If blocked, it is necessary to completely remove all traces of the old roof.Particular attention should be paid to it, especially if it also covered with roofing material.Very often in these works apply the resin.On it simply glued strips of roofing material.

After a while under the influence of environmental conditions (changes in temperature, direct sunlight, etc.) resin cracking.If you leave it, the cracks after a while begins to accumulate water.If the slab is used w / w cooker, the roof should be cleaned before the concrete.If you have removed all ties up to it.It is necessary in this case to check the quality of the remaining ties and renew if necessary.

to clean and dry the roof superimposed special mastic.It is different composition, so you need to specify on the label while it is "setting" and the application conditions (air temperature, humidity).

Harvesting bands and some of the rules laying

As already mentioned, the first layer - a usual roofing material, without stone powder.All strips are stacked one rule - horizontally and upwards.To prevent water from entering under the roofing material, they are stacked with some overlap.When the floor of the second layer should be taken into account that to improve the insulation of the roof joints of the lower and upper layers should not overlap.Therefore, the second layer overlaid with an offset relative to the first.

For the convenience of laying strips produce so.First, the roll is unwound and cut strips to length.Thus it is necessary to make a small allowance.After this the band that you want to apply, slipping back into a smooth, without ridges, "tube".After applying one end to the roof will be only prepared to roll band.

Laying roofing

work should be together.Put a sheet of roofing material on the roof heats up the gas burner.Warms you need to until turns white and does not burn the top film.This indicates that the material and mastic beneath it "ready" for bonding.The strip is glued parts.While one person presses the heated portion to the roof and carefully iron sticking to the quality, the second heats the next section.And so - the band for the band.

With a very smooth surface (smooth plate) stripes better hand held roller.If there are any irregularities, you must manually ensure quality fit tar paper to the roof surface.This is done usually with a cloth.

should be borne in mind that to work with the second layer can start only after the final solidification of the former.
