Repairs from a few hundred dollars, recoats at $2–$4 a square foot, new spray foam roofs from $3.50 a square foot — the published Valley rates, side by side, with a recoat-due calculator and a licensed Arizona roofer who answers the phone.
Three kinds of flat roof make up most of the Valley's calls. Pick yours.
Flat-roof homes1950s–80s ranches and block homes with parapets. Repair, recoat, or a new foam roof over the old one.
Two-storey & townhomesStepped parapets, balconies and rooftop AC. Foam seals the penetrations a flat roof collects.
Small commercialStrip retail, offices and shops with rooftop units — SPF or TPO, with the coating schedule that fits.Most foam roof leaks are a pinhole or a parapet split, fixed in a morning. Same-week in season.
Foam roof repair in Phoenix →A new top coat every 5–7 years is why a foam roof lasts 25+ years. Skip it and UV eats the foam.
Recoating →Seamless, insulating, white. The roof Phoenix flat-roof homes have used since the 1970s.
New spray foam roof →No Valley foam roofer shows these side by side. Here they are, with the source for each.

Valley foam roofers publish recoat intervals from 5 years (Durafoam) to 5–7 (Travek) to 8–12 (Arizona Roof Co). We show the two shorter schedules because Phoenix UV is the worst case.
Don't know the install year? The Maricopa County Assessor shows the home's build year; a roofing permit on file with your city gives the re-roof year.
Rub a dark cloth or your palm firmly across the coating in direct sun.
The NWS monsoon season. Sky Harbor has seen 9.56 in (1984) and 0.15 in (2023) in a season — the roof has to be ready for either.
Recoat and inspection season. Coatings cure fast and the schedule is open. Book before the first storm, not after.
Walk the roof within 48 hours: standing water, lifted edges, new blisters, debris in scuppers. Emergency repair →
Foam roofs cluster where Phoenix built flat and low-slope homes: central Phoenix and Arcadia, south Scottsdale, Tempe near ASU, and west Mesa's 1970s subdivisions. Suburb pages carry the housing-stock and permit notes for each.

This is an independent site. Calls go to our partner contractor, an Arizona ROC-licensed roofing contractor (class CR-42 covers spray foam and elastomeric/silicone coatings). We publish their licence number here and show you how to check it yourself. If they can't take your job, we'll say so.
Published Valley rates: repairs from a few hundred dollars; recoats $2–$4 per sq ft ($4,000–$8,000 on a typical home); new foam roofs $3.50–$9 per sq ft; replacement with tear-off $10–$15 per sq ft. See the cost page for the sources.
25+ years when the top coat is renewed on schedule. The foam itself is not the weak point — the coating is, and it is the cheap part. See lifespan in Arizona.
Almost always repaired. Pinholes, blisters, bird damage and parapet splits are localized; a roof only needs replacement when the foam is saturated across large areas, which a core sample shows in minutes.
Yes — calls are answered by an Arizona ROC-licensed roofer. Foam and coatings require a CR-42 (or C-42 commercial) licence; Arizona's handyman exemption stops at $1,000 and never covers permit work.
