A few days ago we had a good amount of rain that fell over a 36 hour period. During this time, a leak showed its ugly face. I got up into the attic, found the water stream and traced it back outside to the pictures you see below. The shingles are about at half of their life.
For reference, I didn't know the exact names, I cheated and used this that way I could speak half-intelligently on it and probably even make sense.
As you can see from the pictures, the water seems to be rolling up under the edge (where's the drip edge?! even I know that one), getting under the the fascia and on the soffit. I have a good feeling its following that outside wall there and getting inside. Bonus, this is a joint between two, decently long slopes (~12'), so it sees a LOT of volume. As a matter of fact, that last picture, the wood is STILL wet -- it rained 2+ days ago.
Anyway, my idea is to pull the rotten pieces out, nail in some flashing, replace the rotten pieces with fresh ones, maybe put in a drip edge if I can. Anyone else have any better ideas/pointers and also -- if I had someone do this, what would that run?
