The drip edge on my house is peeling back and wasn't noticed until significant water damage to the soffits occurred. Doesn't seem like it was ever actually fastened to the sheathing with nails, nor was it even touching it, rather it was just stuck to the tar paper. The shingles and underlayment overhang the sheathing by ~1.5". I live in Front Range Colorado and the affected section is on the west side of the house.
So a couple questions...
- Is the drip edge 100% necessary here?
- What's the fastest/easiest way to fix this?
