Extend the useful life of roofs across all climates and conditions.
Elastomeric roof coatings provide a seamless barrier against corrosive elements that lead to moisture penetration and damaging leaks, effectively extending the life expectancy of a roof.
At Polyglass, we specialize in designing premium elastomeric coatings that address a wide range of roofing applications and challenges, including the repair and restoration of multi-layer APP and SBS roofing systems, single-ply systems, and metal roofs.
Our white elastomeric coatings can also provide a “cool roof” effect by reflecting harmful UV rays and promoting significant savings on energy costs.
When installed, Polyglass elastomeric coatings protect and extend the life of the roof and allow building owners to avoid costly roof replacements.

What are Elastomeric Roof Coatings?
An elastomeric roof coating is a liquid-applied roofing layer made from acrylic or silicone that cures to form a seamless membrane when applied over the entire roof area.
Because they respond well to changing temperatures and weather conditions, elastomeric coatings serve as an effective “outer armor” for new roof systems.
They may also be applied to existing roofs to extend their service life as an alternative to a complete tear-out.
Generally, elastomeric coatings can be installed over:
- Asphalt
- Aged EDPM or TPO
- Built-up roofing
- APP / SBS cap sheets
- PVC
- Concrete
- Fiberglass
- Metal roofing
- Sprayed polyurethane foam
- Most existing elastomeric coatings
- Rigid coverboards such as Densdeck and Securock
- Exterior grade plywood
- Mobile homes

Frequently Asked Questions
When properly applied, a roof coating can be a highly effective barrier to prevent leaks.
Acrylic (water-based) coatings affix well to a wide range of roof types and provide excellent protection, but they may need multiple coats and take some time to cure. Silicone coatings take less time to cure, can often be applied in one coat, and do well in extreme temperature settings — but they can lose their reflectivity over time without regular cleaning and maintenance. Talk to our experts to determine which is best for your project.
Liquid-applied roofing can be cleaned regularly using a low-power wash, preferably at least once per year.
With proper care and maintenance, a properly applied elastomeric coating can easily last 15-20 years.
It depends largely on your needs. If you are looking for all-around protection with minimal maintenance, an acrylic coating may be right for you. If the building is subject to consistent extreme temperature changes or you need a single-coat application, silicone might be the better option. Talk to our team of experts for more guidance on the best type of roof coating for your needs.
