Roof Replacement Contractors in Phoenix, AZ: What to Ask Before You Hire
Phoenix roofs fail from heat and monsoon wind, not snow, and the three common systems here — concrete tile, spray foam and asphalt shingle — are priced and warrantied completely differently. Arizona also licenses roofing contractors, which gives you a real verification step most states do not.

What a roof replacement costs in Phoenix
A tile roof underlayment replacement — lifting and re-setting the existing concrete tile over new two-ply or synthetic underlayment — runs $9,000 to $17,000 on a typical Valley home in 2026. Full tile replacement with new tile lands between $18,000 and $32,000.
Spray polyurethane foam on a low-slope roof runs $8 to $14 per square foot installed, and asphalt shingle replacement on a 20 to 25 square roof runs $10,000 to $16,500.
Verify the ROC license before anything else
Arizona requires a Registrar of Contractors license for roofing work, and you can look up any license number by name or number on the ROC site in under a minute. Residential roofing falls under the CR-42 / KB classifications.
Ask for the license number in writing, then check it yourself — that it is active, in the right classification, and that the business name matches the one on the contract. Also ask for a certificate of insurance emailed from the carrier and confirm workers' compensation coverage.
Heat and monsoon questions Valley roofs need
What underlayment goes down, and what is its temperature rating? Phoenix attic temperatures cook cheap felt long before the tile fails.
How are the valleys and penetrations flashed for monsoon-driven rain? Most Phoenix leaks are flashing and underlayment failures, not tile failures.
If it's foam: what mil thickness of coating, and what is the recoat interval? A foam roof without a maintained coating schedule fails early.
Is the tile being reused? Expect 3 to 8 percent breakage on lift-and-relay and ask who supplies the replacement tile.
Timing the work
Crews start at dawn through the summer and stop by early afternoon, which stretches a two-day job into three. Booking in late fall or winter usually means faster scheduling and easier working conditions.
Get the roof done before monsoon season rather than during it. Once the first storms hit, every reputable Valley roofer is booked into emergency repair work.

Common questions
How much does a new roof cost in Phoenix?
Tile underlayment replacement runs $9,000 to $17,000, full tile replacement $18,000 to $32,000, and asphalt shingle replacement $10,000 to $16,500 in 2026.
Do Phoenix roofers need a license?
Yes. Arizona requires a Registrar of Contractors license for roofing. Ask for the number and verify it is active and in the correct residential roofing classification before you sign.
How long does a tile underlayment replacement take?
Three to five days on a typical Valley home, longer in summer because crews stop work in the afternoon heat.
Should I replace tile or just the underlayment?
If the tile is sound, a lift-and-relay over new underlayment is the cheaper and more common repair. Full replacement makes sense when tile is broadly cracked or you are changing profile.
