Commercial roofing in Phoenix is priced per square foot, with the number driven by system type, deck condition, HVAC density, and access. SPF foam typically lands at $5.00–$9.00 per square foot installed for a standard 1" foam build (thicker available when R-value or substrate calls for it; tear-off additional if required); single-ply TPO at $6.00–$10.00; mod-bit at $5.00–$8.00.
Recoats on an existing serviceable commercial roof are the highest-ROI move you can make: at a typical Phoenix cost of $1.00–$2.50 per sq ft, a recoat resets the roof's clock for another 5 years.

What drives the price
Building size
Larger roofs are cheaper per square foot. Volume discounts kick in above ~10,000 sq ft.
HVAC density
Rooftop AC, exhaust fans, gas lines, and pipe penetrations all need hand-detailed flashings.
Deck condition
Wet insulation, deteriorated decking, or moisture in the existing system require tear-off and replacement.
Scheduling constraints
After-hours, weekend, or phased work to keep tenants operational adds cost — but we plan around it.
