While knocking doors we met a 90 year old veteran! During the inspection we found hail damage. I met with his insurance and the full roof was approved. While removing the shingles we found a SECOND layer of shingles. We were able to document it and sent the bill to the insurance company. If there are any surprises like this, then we always try and get insurance to cover it first instead of it coming out of your pocket. Customer called and said that there was still some sagging in a section of the roof. Even though we replaced any rotted decking a section of decking appeared to have sagged due to years of having extra weight from the two layers of shingles. We always want to make it right and our customers happy, so we had to go into the attic and reinforce the decking with some 2x4s. This can happen on older homes where the rafters span 24 inches on center. The decking was still good but had a slight sag from the excessive weight. Simple fix and a happy customer!
