Tile Underlayment Replacement in Phoenix, AZ

Tile Underlayment Replacement done the right way in the Valley of the Sun

On most Arizona tile roofs the tile outlives the underlayment by 25 years or more. The original organic felt under your tile typically starts failing around year 18 to 22 from heat and UV exposure, even though the tile on top still looks fine from the street. When that happens, the right fix is almost never a full tile replacement, it's a tile underlayment replacement, also called a lift-and-relay.

Power Peak Roofing specializes in lift-and-relay underlayment replacement across Chandler, Gilbert, Mesa, Scottsdale, Phoenix, and the rest of the Valley. We carefully lift and stack your existing concrete or clay tile, strip the failing felt down to the deck, install premium 250-degree self-adhered Polyglass underlayment, then re-set your original tile on a brand-new waterproof system. It typically costs 30 to 40 percent less than a full tile replacement and adds 25+ years of roof life.
