Spray Foam Roofing in Mesa, AZ

Mesa spray foam roof costs, explained

Typical totals from our price sheet for a 1,500 sq ft flat roof: about $7,125–$9,000 to foam over the existing roof ($4.75–$6 per square foot), or $4,800–$6,300 on new construction ($3.20–$4.20 per square foot). See every range on our pricing page.

Foam is priced roof by roof. On a Mesa house, these are the things that move the number up or down:

• Can it go over the old roof? Dry, well-attached rolled roofing or hot-mop can usually stay in place under the foam. Wet or blistered sections get cut out first, and that adds labor and disposal.
• Square footage and thickness. A thicker layer means more material and more insulation.
• Finish. Elastomeric coating or a gravel surface, and how many coats go on.
• Details. Parapet walls, AC stands, plumbing vents, and the joint where a flat section meets a pitched shingle or tile slope.
• Deck condition. A low spot that has leaked for years often has soft wood under it, and that gets replaced before we spray.

The flat roofs hiding in Mesa's older neighborhoods

Mesa has more flat and low-slope roof than people expect. In Fraser Fields, the postwar ranch houses between University and Main can pair composition slopes with rolled or hot-mopped roofing over porches and back rooms. Apache Country Club Estates, the tiki-themed tract south of Broadway near Power Road, mixes flat and low-pitch roofs with its A-frame gables. The Evergreen Historic District includes Pueblo Revival houses, a style known for flat roofs behind parapets.

Those low sections hold water after a storm, and the laps in rolled roofing are where it gets through. Foam takes the laps out of the picture. We spray it on wet; it puffs up and hardens into a closed-cell layer that grips the whole surface with no seams. It wraps itself around vents and curbs, so the flashing is built in. An elastomeric coating goes over the top to shield it from UV.

What foam does in a Mesa summer

A foam layer is insulation sitting on top of your house. The back bedroom or converted garage under a flat roof is often the hottest room in a Mesa ranch, and foam slows that heat down before it reaches the ceiling. It's walkable, too, so servicing the AC up there doesn't mean cracking anything.

The coating is what the sun wears down. Keep it recoated on time and the foam underneath stays protected; let it go too long and UV starts eating the foam itself. We check coating thickness and wear on every foam roof we inspect and tell you straight whether it needs attention.

Metal patio covers and RV shelters take foam well. On metal, the first coat is a light tan; once no bare spots show through it, the white coats follow. Read how the base coat protects foam on metal and what foam did to the temperature of one metal roof in the Valley.
