Dead valley and trim board repair in Powell

Powell, Ohio · April 2025

What we found and what we did

The homeowner had a leak, and inspection traced it to a dead valley, where a roof valley runs into a wall, and old trim boards at that wall. The crew opened the roof at the wall, replaced water-damaged decking, installed new step flashing and ice and water shield, replaced the old trim with PVC trim boards, and shingled the area back in with GAF HDZ shingles in Mission Brown.

Why dead valleys and wall trim leak

When a valley ends against a wall, all the water it carries hits one spot. If the step flashing there is missing or the trim boards behind it have rotted, water gets behind the siding and into the wall. Replacing the rotted wood and flashing the junction correctly stops it. See our valley flashing repair service.
