| Silicone recoat | usually a bit more than acrylic |

| New spray foam plus coating | about $5–$9 |
Small roofs and patio covers often have a minimum charge because setup costs the same whether the roof is 200 square feet or 2,000.
What makes it cost more
- Foam repairs. Wet or eroded foam has to be cut out and replaced.
- Peeling old coatings. Scraping off loose layers takes time.
- Lots of openings. Every cooler, skylight, vent and mount is hand work.
- Parapet and canale work. Caps, corners and canales add labor.
- Access. Two-story walls, tight side yards and steep driveways slow things down.
- Silicone vs acrylic. Silicone material costs more.
What makes it cost less
- Catching the roof before the foam is exposed
- A simple roof with few openings
- Good drainage, so no low spots to rebuild
- Doing the house, garage and patio in one visit
Comparing estimates
Two prices for "recoat the roof" can describe very different jobs. Line them up on the same points: what prep is included, what repairs, which product, how thick, how many coats, and what the warranty covers. The lowest price often means less coating on the roof.
Waiting has a price too
A recoat over sound foam is one of the cheapest roof jobs there is. Wait until the foam is exposed and breaking down, and the job can become re-foaming — often more than double. See how long a coating lasts.

Common questions
Do you charge for estimates?
No.
Is a recoat cheaper than a new roof?
Much cheaper, when the foam underneath is still sound.
Can I finance it?
Ask when you call. Some homeowners also look at local and federal home repair programs.
