How long does underlayment last under tile in Phoenix?

Underlayment life depends on the product and sun exposure, but many tile roofs in Phoenix need underlayment replacement after 15–20 years. High-grade SBS or modified bitumen underlayments last longer under desert conditions than standard products.

Will my HOA require a specific underlayment or tile profile?

Many Phoenix HOAs have approved-material lists. We'll review your community's guidelines and make sure the underlayment and any replacement tile meet them.

What Tile Roof Underlayment Involves

On a desert tile roof the concrete or clay tiles can last decades, but the underlayment beneath them — the waterproof layer that actually keeps water out of your home — has a much shorter service life under Arizona sun. Tile underlayment replacement means carefully removing the tile, replacing the dried-out underlayment with a high-grade modified bitumen or SBS product, renewing the flashing, and reinstalling your existing tile. It's how most tile homeowners in Phoenix get another 20 years out of a roof without a full material replacement.

Signs You Need Tile Roof Underlayment

Signs your tile underlayment is due for replacement include leaks that appear during monsoon rains even though the tiles on top look fine, underlayment visible at the eaves that is cracked or crumbling, soft spots in the roof deck, or a tile roof that is 15–20+ years old in the Phoenix sun. Because the tile hides the underlayment, age and leaks are the clearest indicators.

Our Roofing Process in Phoenix, AZ

We inspect the roof, assess the condition of the tile and the deck, and provide a written estimate. On installation day we stack and carefully remove the tile, tear off the old underlayment, repair any damaged decking, install new high-grade desert underlayment and flashing, and reinstall your existing tile with attention to course alignment and ridge detailing. Ken remains directly involved throughout the customer experience.

Tile Roof Underlayment Built for the Arizona Desert

In Phoenix, the sun is the single biggest factor in how long a roof lasts. Year-round UV exposure, summer highs regularly above 110 F, and monsoon storms in July and August dry out underlayment, bake flat roof coatings, and stress flashing and ridge caps. Tile Roof Underlayment performed by a contractor who understands the desert means the right materials are used in the right places -- desert-rated underlayment beneath tile, properly installed flashing at every penetration, and coatings maintained before the foam beneath them degrades.

We do not install new spray foam roofing systems -- but we do repair existing spray foam roofs. We will be straightforward about whether your roof is one we service, so you can make an informed decision.
