Signs your foam roof needs attention
- Coating that's chalky, thin, cracked or peeling
- Foam showing through: yellow, tan or darkened and eroded
- Blisters, soft spots, or holes from birds or foot traffic
- Water standing more than a day or two after a storm
- Leaks at parapets, scuppers or around A/C units
Recoat, repair, or re-foam?
| Condition | Typical approach |
|---|---|
| Coating worn, foam intact | Clean, prep and recoat |
| Localized foam damage | Cut out, re-foam the area, then coat |
| Wet or widely failed foam | Remove affected areas, or re-roof |
Keep it lasting
- Keep scuppers and drains clear, especially after dust storms.
- Ask HVAC techs to use walk pads.
- Schedule a check before monsoon season.

Foam roofing FAQ
How often does a foam roof need a recoat?
It depends on the coating type, its thickness and exposure. Ask your contractor what interval they recommend, and have the roof checked periodically so you recoat before the foam is exposed.
What license does a foam roofing contractor need?
Nevada's NAC 624 has a C-36 classification for polyurethane foam and coatings, including weatherproof roofs. Some roofing contractors hold C-15a as well. Verify at nvcontractorsboard.com.
Why does water pond on my flat roof?
Low spots, blocked drains or scuppers, or settling. Standing water speeds up coating wear. A contractor can build up low areas with foam or improve drainage.
