Challenge: Leaks Caused by Deteriorated Underlayment Beneath Tile

Concrete tile roofing systems are designed to last for decades, but the underlayment beneath them serves as the true waterproofing barrier. Over time, exposure to Arizona heat and seasonal weather can cause underlayment to degrade, leading to leaks around valleys, penetrations, and flashing areas.

At this Cornville, AZ home, the tiles themselves remained largely serviceable, but the underlayment had reached the end of its functional lifespan. The challenge was to remove and reset the tile carefully, replace the waterproofing system, and ensure all roof penetrations were properly sealed to prevent future moisture intrusion.
