Flat & Low-Slope Roofs
Silicone and reflective roof coatings
A roof coating is a fluid-applied membrane, usually silicone or acrylic, rolled or sprayed over a sound flat or metal roof. It seals small cracks and fasteners and reflects sunlight. It doesn't fix a roof with wet insulation or failed decking; that has to be repaired first.

Coatings make sense on aging but sound flat roofs and exposed-fastener metal roofs, where they can add years of life for much less than replacement. White reflective coatings cut surface temperatures in sunny climates from the Southwest to the Southeast.
Silicone tolerates ponding water better than acrylic. Preparation is most of the job: cleaning, repairing seams, and confirming the roof is dry underneath. Application needs a dry forecast and temperatures within the product's range, which limits the season in colder states.

What affects the cost
Prices depend on what the roofer finds, so the contractor quotes after inspecting. These are the main factors:
- Coating type (silicone vs. acrylic)
- Required thickness and warranty length
- Repairs needed before coating
- Roof size and access
- Number of penetrations
Frequently asked questions
Can a coating go over shingles?
Coatings are generally meant for flat and metal roofs, not asphalt shingles. Shingle roofs need repair or replacement instead.
How long does a roof coating last?
Typically about 10 to 15 years depending on thickness and product, and many can be recoated later.
