Underlayment Damage & Leak Repair
Scope of Work
Targeted tile roof underlayment restoration and leak repair in San Diego. Detached concrete tiles across an active 400 sq ft leak zone, excised decayed organic felt paper, replaced dry-rotted CDX plywood sheathing, installed dual-layer high-temp synthetic underlayment with self-adhering valley membrane, and re-laid tiles with stainless steel fasteners.
Materials & Specifications
The Problem & Local Climate Challenge
After consecutive winter atmospheric river storms, the homeowner experienced an active ceiling leak dripping directly into their primary bedroom. While the exterior concrete roof tiles appeared intact from the ground, water was running underneath displaced tiles and finding fissures in the dried-out, 30-year-old felt paper. The leak had already begun softening the structural plywood decking and attic framing.
Technical Solution & Engineering Execution
As experienced roof leak repair contractors in San Diego, we tracked the moisture path using infrared thermal imaging. We detached three courses of tile above the leak origin, removed spongy CDX sheathing, and sistered damaged rafter tails. We applied dual-layer synthetic high-temperature underlayment, reinforced with self-adhering ice-and-water shield along the eave and valley flashings. We re-laid the concrete tiles, sealed all tile penetrations, and conducted a 30-minute high-pressure water test to guarantee absolute leak-free protection.

Project Summary
“We dealt with persistent leaks after winter storms until Rise Up found the torn underlayment beneath our tile roof. They repaired the decking, replaced the underlayment, and our ceiling has stayed bone-dry ever since.”
