Roof Replacement at Comistas Drive, Walnut Creek

This roof replacement at Comistas Drive in Walnut Creek began after the homeowner reported ongoing leaks. During our inspection, we found worn shingles near the solar panels and areas of dry rot with damaged plywood along the side of the home.

After approval, we promptly scheduled the project, replaced the compromised decking, repaired the dry rot, and installed new GAF Timberline® shingles to match the existing roof color. The result is a durable, leak-free roofing system built for long-term protection.
