Flat Roof Foam & Coating in Phoenix

Sprayed foam builds slope to the drains; white coating throws the heat back — in Phoenix and all around it.

Flat roofs live or die by two things in Phoenix: drainage and coating. Sprayed polyurethane foam fills low spots and builds slope toward the drains, then a white elastomeric topcoat seals it and throws the heat back instead of soaking it in. We work parapets, scuppers and rooftop equipment — residential and commercial both.

What's included

The coating is the sacrificial layer: it takes the UV so the foam does not, and it is designed to be recoated on schedule. A foam roof that gets its recoats can run for decades; one that skips them becomes a tear-off. Ponding water is the other enemy — if water still stands a day after a storm, the roof needs slope, not another patch.

How we work

Inspect

Drainage, ponding, coating condition, penetrations.

Prep

Repairs and cleaning so the new system bonds.

Foam

Slope built where the water needs to go.

Coat

White elastomeric, sealed edges, clean lines.

Flat Roofs: Foam & Coating by city

The Valley is not one market — a 1950s block ranch in central Phoenix, a Tempe rental near ASU and a Scottsdale HOA home are three different jobs.

Common questions

How long does a foam roof coating last?
Foam roofs are designed to be recoated periodically — the coating is the sacrificial layer that protects the foam from UV. We tell you the manufacturer's schedule for the product on your roof and what it looks like when it is due.
Water stands on my flat roof after it rains. Is that normal?
A day of drying is normal. Standing water past that is ponding, and ponding is where coatings fail first. The fix is slope — foam built up toward the drains — not another layer of paint over the puddle.
Do you do commercial flat roofs?
Yes — residential and commercial both, including roofs with drains, scuppers and rooftop equipment. Tell us the building and we will look at it.
