Asheville Roofing Contractor Deals With the Rot
This roof has some serious issues. First, there is a lot of rotten roof decking due to long-term leaking and no drip edge at gutters allowing water to get off roof decking. Plus, there is a low slope of about a 3/12 (almost too flat for shingles) with leaves, sticks, and lots of debris building up on the shingles. This allows water to wick under the shingles causing rusted nails and leaking roofs.
The shingles are cupping at the edge of the roof, creating an area for the water to penetrate
And this is a hole in the corner where water is coming in.
This section of the roof has a lot of standing debris. This allows water to penetrate the shingles allowing moisture to with under them easily. There is a good bit of rot along the edge of this section of the roof.
As you can see, the edge of the shingles is cupping. This allows water to flow underneath the shingles and get on the roof, allowing the wood to rot.
This roof section has severe wood rot caused by the leak just 18 or 20 inches up the roof.
