How to avoid the mistakes

Proper roof decking
We initially start roofing by roof decking. It is like a basement or foundation for roof. It should be constructed carefully so that we can fix remaining roof also properly. Fixing of shingles depends on the decking as they will be fixed on the decking. Make sure the decking is done in such a way that the roof will not be affected by moisture.

Fixing shingles
Shingles we use should be new and with high quality. Shingles should be fixed without any gaps so that any moisture or dirt doesn’t accumulate in the gaps and damage the roof.

Nailing process
To fix the nails fast, we shouldn’t use short nails. We should use the nails in such a way that the shingles are fixed in to the deck properly. This will avoid loosening of shingles.

Usage of low quality flashing or old flashing
There may be a chance that any material other than metal for flashing would be incompletion of roof as it acts as moisture barrier. Usually flashes are fixed in such areas like chimneys, skylights, roof valleys etc. There shouldn’t be any gaps while fixing flashes. Old flashes should not be used by patching, cutting edges etc. Replacing also should be done with new ones.

Proper usage of roof overhang
Though it gives a good look to the house, we should take care while overhanging the eaves. Roof should be properly overhung. It provides protection from wind.

Protect the roof from moisture
Basically, we observe moisture at many places in our house. That is because there may be mistakes in the construction of a roof. The roof should be in such a way that rain, ice, and snow etc should not affect it. There shouldn’t be any place for them to enter the house. Hence the roof shouldn’t have gaps.

Providing proper ventilation
When there is no proper flow of air in to the house, there is a chance of moist in house. Moisture damages the entire house. Hence we need proper ventilation so that the air flow will be there.
