Do this only after the water has completely dried up and there is no danger of you slipping and falling during the inspection.

Replacing roof shingles can be done in two ways. Either you can rip up the old shingles completely, dispose them off and replace with brand new shingles – either 30-year or 40-year shingles depending on your budget or go for second layer of shingles over the old layer.

In the second method the roof is prepared, old worn-out, warped, curled and misshapen shingles are removed and surface is made as even as possible. Only, then is the second layer of shingles is installed. This saves money as you don’t have to pay for removing and hauling away of the old debris.
