Roofing is a job for the professionals. It is the largest area of the home that can require work, and it can be the most dangerous work. The only way to inspect a roof for damage or holes that could leak water is to climb on the roof and perform a visual inspection. Sometimes, the roofing shingles need to be lifted slightly to view the underlayment to check for rotten wood. Shingles may be curled or loosened to the point where the underlayment is exposed.
The next check should be made in the attic where water may have run down the walls and into the living area of the home. This can be a sign that black mold has formed between the walls, and this is a condition that should not be allowed to continue. There may be black mold in the attic if the water has accumulated.
