Spongy, "Bouncing" Roof Decking Over 24-Inch Rafters
Most 1950s and 60s ranches in Spring Branch East and Central were built with thin 3/8-inch plywood sheathing stretched across wide 24-inch rafter spans without modern support clips. After six decades of 150°F attic heat, the glue inside the wood dries out and separates. You might not see a water spot on your ceiling yet, but walking on the roof feels like stepping on a mattress. Nailing new shingles over bouncing wood causes nails to back out and shingles to blow off in the first storm.
We do not just nail shingles over bad wood. Through our Roof Deck Repair service, we cut out delaminated 3/8-inch sheets, install structural H-clips along all panel edges, and lay down solid, modern CDX plywood to give your roof a completely rigid foundation before shingling.
