New foam or a recoat?
| What you see | Likely answer |
|---|---|
| Coating worn thin, foam still covered | Clean, repair and recoat |
| Some exposed brown foam in spots | Repair those areas, then recoat |
| Large areas of crumbling or wet foam | Remove and re-foam those areas or the whole roof |
| Old built-up roof, no foam yet | New foam system if the old roof is dry and sound |
What a new foam roof includes
- Prep: remove failed material, clean and dry the surface
- Sprayed foam with extra thickness to build slope where needed
- A curved foam cant up the parapets
- Canales sealed into the foam
- Protective coating in the specified thickness
Keeping it going
Look at the roof once a year, clean the canales after the cottonwoods drop, and recoat before foam shows through. That's how foam roofs in Corrales reach their full life.
Roofing questions
How often does a foam roof need recoating?
Every several years, depending on the coating and exposure.
Can foam go over my old roof?
If it's dry and sound, often yes.

Sometimes; keeping it coated and repairing pecked spots helps.
