Rotting and Splintering Roof Decking
This roof was so old that the boards under the shingles were splintering, waterlogged, and rotting. They needed to all be replaced.
Ceiling Collapsing from Water Damage
So much water had leaked through the roof that it soaked the ceiling around this vent and it was collapsing into the home.
There were loose and detached shingles in many places.
More Rotting Wood Under Shingles
This is another look at the wood under the shingles. This was especially unsafe because this is where the chimney was attached. The area needed to be replaced and the chimney re-sealed and supported.
