Silicone, acrylic and cool roof coatings
A coating seals a sound roof, turns it white and reflective, and adds 10 to 20 years without a tear-off. In San Antonio heat, it also keeps the roof far cooler.
Takes under a minute. Add the roof size and any photos you have.

A coating protects a roof that is still sound. It cannot save a roof that is wet inside. Here is how we tell the difference.
Consider instead
Localized leaks
You're in the right place
Aging but dry
Consider instead
Wet or failing
Not sure? Core cuts and a moisture scan show whether your roof can be coated or needs more work first.
Commercial roof coating in San Antonio has to handle intense UV, 100-degree days and sudden downpours. These are the systems we use and where each one fits.
Best for strong UV and ponding water; often the choice for flat TPO, EPDM and modified bitumen roofs.
Lower cost and highly reflective; best on roofs that drain well, including metal.
Tough and impact resistant, used where foot traffic or hail is a concern.
White, reflective finishes that keep the roof surface far cooler in summer sun.
Rust treatment, fastener and seam sealing, then a full coating system.
Adds insulation and fixes low spots under a protective coating.
Test, repair, clean, then coat, in that order.
Core cuts and a moisture scan confirm the roof is dry enough to coat.
Coating type, thickness, warranty term and a fixed price.
Wet areas replaced, seams and flashing repaired, the roof cleaned and primed.
Base and top coats at the thickness the warranty requires, with fabric at seams.
Thickness checked, photos taken and the warranty registered.
Proof the coating went on right.
Prep, repairs and the finished coating.
Repaired and coated areas mapped.
No surprise change orders.
Coating and workmanship terms in writing.
Coatings are priced per square foot after the assessment. These four things move the number most.
| Typical scope | Typical range |
|---|---|
| Acrylic coating, applied | $0.50 to $2.00 per sq ft |
| Silicone coating, applied | $1.50 to $4.50 per sq ft |
| Full restoration: repairs, prep and coating | $3 to $9 per sq ft |
| Spray foam with coating | $4 to $8 per sq ft |
Under a manufacturer warranty? We check whether a coating affects it before we start.
Large, flat, sun-baked roofs over air-conditioned space see the biggest cooling benefit.

A coating is not a patch for a failing roof. It is protection for a good roof you want to keep.
How we approach every coating
We coat commercial roofs across San Antonio and nearby towns, inside and around Loop 1604. Drive times are from downtown.

Yes. Cool roofs pay off most in hot, sunny climates. The U.S. Department of Energy says a reflective roof can stay more than 50°F cooler than a conventional roof under the same conditions, which lowers the air-conditioning load below.
It depends on the roof. Silicone handles ponding water and strong UV best, so it suits flat roofs. Acrylic costs less and works well on roofs that drain quickly, including metal.
Most elastomeric coatings last 10 to 20 years when applied at the right thickness and maintained. Many can be recoated at the end of their life instead of replacing the roof.
Yes, if the leaks are limited and the insulation is dry. We repair the leaks and replace any wet areas first, then coat. A coating over wet insulation traps the water and fails.
A coating alone usually runs about $0.50 to $2.00 per square foot for acrylic and $1.50 to $4.50 for silicone. A full restoration with repairs and prep typically runs $3 to $9 per square foot.
No. Coatings go on top of the existing roof without a tear-off, so work below continues. We plan around rooftop equipment and air intakes.
