We performed a targeted tile roof repair on this residence to address water intrusion occurring near a structural transition wall. After removing the existing concrete S-tiles, we identified and replaced water-damaged plywood decking and deteriorated underlayment that had compromised the roof's seal. Our team focused on restoring the structural integrity of the roof deck before beginning the waterproofing phase. We installed high-performance Boral TileSeal underlayment and reinforced the wall-to-roof transitions with professional-grade flashing sealant and roofing cement. The original tiles were then precisely reset and secured with fresh mortar beads to ensure a seamless finish. This repair restored the building envelope and provided long-term protection against heavy rainfall in Boca Raton.
