Challenge: Aging Underlayment Causing Active Interior Damage

The primary issue stemmed from deteriorated tile underlayment that had reached the end of its service life. While the exterior tile system appeared intact, the waterproofing layer beneath had failed, allowing moisture to penetrate the roofing assembly.

This led to visible staining on interior ceilings in multiple areas. The challenge required addressing both the hidden roofing failure and the cosmetic and structural drywall damage inside the home. Care also had to be taken to preserve and reuse existing roof tiles while ensuring full waterproofing restoration.

• Careful removal of existing concrete roof tiles for reuse
• Complete removal of deteriorated underlayment across all roof sections
• Installation of premium synthetic underlayment for enhanced durability and water resistance
• Replacement of flashing and sealing of all roof penetrations to prevent future leaks
• Installation of new 1″x2″ wood battens to support tile reinstallation
• Reinstallation of existing tiles with replacement of any damaged pieces
• Installation and waterproofing of vents and roof openings
• Interior protection measures to safeguard flooring and belongings during repairs
• Drywall repair at two ceiling locations, including patching, texturing, and repainting

Result: Restored Protection and Interior Peace of Mind

The completed project delivered a fully renewed roofing system capable of withstanding future weather exposure while maintaining the home’s original tile aesthetic. The new synthetic underlayment significantly improved waterproofing performance and long-term durability.

Inside the home, ceiling stains were eliminated through professional drywall repair and repainting, restoring a clean and cohesive appearance. The homeowner now benefits from both structural protection and renewed confidence that the issue has been properly resolved.

Trust & Proof: Proven Materials and Workmanship Assurance

This project utilized high-quality synthetic underlayment designed for long-term performance beneath tile roofing systems. The installation included proper flashing, sealing, and ventilation components to ensure a complete roofing solution.
