What is an elastomeric roof coating?

Last updated: August 17th, 2016

Elastomeric roof coatings are more viscous (45% or more volume of solids per volume) and elastic than standard paints or coating products. An elastomeric roof coating has high viscosity (“thicker”) and elasticity (“flexible”) making it less likely to crack or fail under strain and weather conditions.

This type of roof coating has several advantages over a standard paint product including higher durability against weather and corrosive conditions. Maintenance is also easier and can be as simple as an annual recoat. These coatings create a stronger adhesive bond to the underlying surface creating a thicker protective layer. Higher viscosity also means coverage is lower than a less viscous standard coating product e.g. additional material is typically required with an elastomeric roof coating which can make it costlier than a product that has more coverage. This can be an ideal option for exposed flat surfaces like the commercial roof above.

Applying Elastomeric Roof Coating

Elastomeric roof coatings like the one above are easy to apply and can adhere to a variety of surfaces including rolled roof, BUR, RV roofs and wood.
