Foam Roofs in Anthem: What a Recoat Actually Includes and How Often You Need One
Foam isn't 'install and forget' — and that's the point. A proper recoat every 4–6 years is what gives foam its long lifecycle. Here's what's actually in a recoat.
Foam roofing — sprayed polyurethane foam under an elastomeric coating — has a reputation in some quarters for being maintenance-heavy. That reputation is mostly wrong, and where it's right, it's because the recoat schedule was skipped.
What the coating actually does
The elastomeric coating is the waterproofing layer. It is also the part that sacrifices itself to UV. Think of it as a wear surface — it is supposed to slowly degrade, and you are supposed to refresh it on a known cycle. In Anthem's UV environment, that cycle is roughly four to six years.
What a recoat includes
- Full power wash and surface inspection.
- Repair of any damaged foam — fractures, isolated wet spots, bird damage.
- Primer where the coating manufacturer requires it.
- Two coats of elastomeric coating at manufacturer-spec thickness.
- Granules embedded into the top coat for foot traffic and additional UV protection.
- Fresh sealing at every penetration: parapets, scuppers, vents, drains, skylight curbs.
- Photo documentation, written warranty, and the next recoat date on the calendar.
When recoat isn't the answer
If the coating has been allowed to fail past the point where the foam itself is degrading — saturating, fracturing, debonding from the deck — then a recoat is throwing good money after bad. In that case we'll inspect, document the moisture intrusion, and quote a rebuild. The good news is that a foam roof with a documented recoat history almost never gets to that point.
