This is a good example of a new roof installed by an incompetent, unlicensed roofer.

• 1/4" wide staples when the manufacturer required galvanized nails or 1" wide staples.
• Metal valley without sufficient clearance to the cut of the composite shingle.
• Insufficient over-hand at the gutters and sides.

The silicone caulking indicates a leak above the living room, Water stains on the sheathing indicating wicking into plywood. !/4" staples are not sufficient to hold the shingles in a moderate wind storm.

The seller claimed the roof leak had been fixed. Guess who fixed it.  My client, the buyer, got a new roof installed, by a licensed contractor, as part of purchase.
