Original Asphalt Shingles
Here is the view of the roof before the removal of the damaged shingles.
Air vent seal damage
The last attempt to fix the seal around the vent by a previous contractor was a failure. The seal did hold and is allowing water to seep in.
2 layers of old shingles
We started ripping up the top layer of asphalt and found additional shingles.
Decking damage
We also uncovered substantial damage to the underlayment and decking, which needed replacement. We found rodent droppings that suggest a larger problem looming.
