Two common situations
Re-foaming an old foam roof
Foam that's been bare for years loses thickness, gets pitted and may hold water in places. If most of it is still dry and attached, we can clean it and spray a new layer of foam over the top, then coat it. That restores thickness and lets us improve the slope toward the canales.
Foam over an old flat roof
Older Rio Rancho homes sometimes have built-up tar and gravel or rolled roofing under years of patches. In many cases, after loose gravel and wet sections are removed, foam can be sprayed right over the old roof rather than tearing everything off. Your inspection decides whether that's sound.
What a new foam roof gives you
- One seamless surface with no laps or seams to split
- Added insulation on top of the ceiling
- A chance to fix flat spots and steer water to the canales
- A light, reflective finish once it's coated
Weather and wind
Foam is sprayed as a liquid and expands in seconds. It needs dry surfaces, moderate temperatures and, above all in Rio Rancho, calm air. We plan spray days around the forecast and use wind screens and masking to protect cars, stucco and neighbors. On gusty days we don't spray.
The coating still matters
New foam is only half the job. It needs a full UV coating soon after it's sprayed, and that coat needs maintenance like any other. See foam roof recoating.
Is it time?
Compare the options in recoat, new foam or TPO. If the decking underneath is rotten or the roof is soaked, a tear-off may be the only honest answer.
Call (505) 448-1467 for an inspection. We'll tell you if a recoat will still do the job.
Common questions
How thick is new foam?
Roofing foam is commonly sprayed at least an inch thick, often more where slope is being built up.
Does foam add much weight?
No. Roofing foam is very light compared with gravel or tile.
Will it help my energy bills?
Added insulation plus a reflective coat can help, especially in rooms right under the roof.
