Spray Foam Roofing in Chandler, AZ

Budgeting for a spray foam roof in Chandler

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.

On Chandler homes, foam jobs tend to be smaller areas with a lot of detail. Here's what sets the budget:

• Area. A single patio roof is a short job; the full flat roof on an older home is bigger.
• Tie-ins. Where foam meets tile or shingle, the transition has to be built carefully, and that takes labor.
• Existing surface. Dry, attached roofing can stay under the foam. Wet roofing and soft decking come out first.
• Coating. The elastomeric product and how many coats go on.
• Metal. Foaming a metal patio cover or shop adds a base coat under the white.

Where Chandler homes hide flat roofs

West Chandler's late-1970s houses, in subdivisions like Silvergate, have composition shingle roofs. If your house from that era has a patio roof or room addition that barely slopes, that's the part to watch. Rolled roofing on a low addition opens at its laps long before the shingles around it wear out.

In the tile communities, flat roofs show up as smaller pieces: a low section between slopes, a covered patio, a casita. In neighborhoods with mature landscaping, like Ocotillo, those spots also collect leaves and dust that hold water against the roof.

Foam handles those spots well. It's sprayed on wet, grows as it cures, and ends up as one closed-cell layer stuck to the deck with no seams for water to find. It builds its own flashing around pipes and vents, which is where flat roofs tied into tile usually leak. An elastomeric coat goes on top, and gravel is an option on some roofs. Leaks on these small sections usually trace back to one bad detail that let water in.

Foam, heat and metal in Chandler

The room under a flat roof is often the hottest in a Chandler house by July. Foam is insulation on the outside of the deck, so the heat slows down before it reaches the ceiling. You can walk on it, too, which matters if your AC sits up there.

Metal patio covers and detached shops take foam well. On metal, the foam lowers the surface temperature, and a light tan first coat goes down ahead of the white, so a missed spot can't hide. Read what foam does for the heat under a metal roof for more.

The coating needs a recoat from time to time, since it's the part that faces the sun. After an inspection we'll tell you where yours stands and what it will need next.
