Recoat · the job that saves the roof

Foam roof recoating in Phoenix

The foam under your coating can last decades. The coating can't — Phoenix UV oxidises it in 5–7 years. A recoat is a few thousand dollars; a roof that was never recoated is a tear-off.

YOUR AVERAGE FOAM ROOF — foam for insulation and slope, a thin top coat for the sun. The coat (peeled back here) is the part that wears out, and the part that is cheap to renew.

Recoat-due calculator 5 / 7 year schedules

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.

What a recoat costs

Roof	At $2/sq ft	At $4/sq ft
1,500 sq ft	$3,000	$6,000
2,000 sq ft	$4,000	$8,000
2,500 sq ft	$5,000	$10,000

Travek publishes $2–$4/sq ft; KY-KO describes residential recoats as "low-to-mid four figures." Repairs needed before coating, silicone vs acrylic, and access move the number.

What a proper recoat includes

Power-wash to bare, sound coating; let it dry fully (one reason April–June is the season).
Cut out and refoam blisters and saturated spots; patch pinholes and bird holes.
Primer where the manufacturer requires it (silicone over acrylic almost always does).
Two passes of elastomeric acrylic or silicone to a stated dry mil thickness — 20–30 mils is typical; ask for the number.
Granules in bird-prone areas; walk pads at HVAC units.
A dated, written warranty naming the product.

Acrylic or silicone?

Acrylic elastomeric is the Valley default: cheaper, breathable, easy to recoat again. Silicone resists ponding water and UV longer and is the better choice on low-slope roofs with standing-water history — but once silicone is on, only silicone goes over it. The coating page has the comparison table.

Questions people ask

How often should a foam roof be recoated in Phoenix?

Published intervals: every 5 years (Durafoam), 5–7 years (Travek), 8–12 years (Arizona Roof Co). In full Phoenix sun with no shade, plan on the shorter end and let the chalk test decide.

What happens if you never recoat a foam roof?

UV degrades the exposed foam a fraction of an inch per year; it yellows, pits, absorbs water and loses R-value. After enough years the saturated foam has to be cut out or the roof replaced — $10–$15/sq ft instead of $2–$4.

Can you recoat over silicone with acrylic?

No — acrylic won't bond to silicone. Silicone over acrylic works with the right primer. Ask what's on the roof now before you accept a quote.

Do I need a permit to recoat in Phoenix?

Recoating is maintenance and is not treated as a re-roof; full replacement requires a Phoenix building permit ($135–$720 by project value). Confirm with Planning & Development for your city.
