What it is
Elastomeric roof coatings are thick, rubbery coatings, most often acrylic. They go on as a liquid and cure into a flexible membrane that bridges hairline cracks and moves with the roof. White versions reflect a large share of sunlight.
Best uses
- Recoating foam roofs that drain well
- Restoring built-up and modified roofs after prep
- Coating metal roofs on homes and outbuildings
Limits at altitude
Water-based acrylics need warm temperatures and dry conditions to cure, and they can be damaged by dew or frost before they set. In Los Alamos that narrows the application window. They also don't like water standing for days, so roofs with ponding may need silicone or slope repair.
Thickness matters
A coating's life depends on how much is on the roof. Ask for the product name and the coverage rate in your estimate.

Common questions
Is elastomeric good for snow?
It handles freeze-thaw movement well. Areas where snowmelt sits for long periods may do better with silicone.
How white will it stay?
It stays bright for years, especially if the roof is cleaned occasionally.
