Tile roof underlayment replacement in Gilbert and the Phoenix Valley.
Concrete and clay tile often lasts 50 years or more in Arizona. The underlayment underneath usually does not. When it wears out, we lift your tile, replace the underlayment, and put your original tile back.
Why tile roofs leak in the Phoenix Valley
Tile is not what keeps water out of your home. It sheds most of the rain and shields what is underneath from the sun. The real waterproof layer is the underlayment, a membrane installed on the roof deck below the tile.
In the Valley's heat and UV, that underlayment commonly wears out in about 20 to 25 years, often decades before the tile does. It dries out, turns brittle, cracks and tears, especially at eaves, valleys and around penetrations. Then a monsoon storm drives water past the tile and finds the gap.
Signs your underlayment is failing
- Water stains on ceilings or walls, especially after a storm
- Leaks that come back after a "repair"
- Brittle, torn or crumbling underlayment visible at the eaves or under a lifted tile
- Slipped, cracked or missing tiles that expose the layer underneath
- A tile roof that is 20 years old or more and has never had its underlayment replaced
You often can't see underlayment damage from the ground. That is why our inspection includes the roof surface and the attic, with photos of everything we find.
Repair, re-underlayment or full replacement?
Repair makes sense when the damage is isolated and the underlayment around it is still sound. Re-underlayment (sometimes called a lift and relay or a tile reset) makes sense when the underlayment is worn across the roof but your tile is in good shape. Full replacement makes sense when the tile itself has failed, or when your HOA requires a new profile or color.
We put our recommendation in writing, with photos tied to each finding, and show the options side by side so you can compare them with other bids.
