We performed a targeted residential roof repair in Sunrise to address a persistent leak originating in the roof valley. Our team removed damaged asphalt shingles to inspect the underlying plywood decking and structural rafters. We identified compromised flashing and underlayment that required immediate attention to prevent further interior water intrusion. To ensure a watertight seal, we installed a new waterproof membrane and applied professional-grade mastic along the critical valley transition. We replaced the removed sections with matching asphalt shingles and reinforced the flashing around nearby plumbing vents. The finished repair restored the integrity of the roofing system and improved drainage in a high-traffic water area.
