Elastomeric Roof Coating

What This Service Involves

A roof expands and contracts every time the weather shifts, and rigid coatings eventually crack under that constant movement. Elastomeric coatings are engineered to flex with the substrate, bridging hairline cracks and keeping the waterproof layer intact through thousands of thermal cycles. That elasticity is valuable across Puget Sound, where damp cool nights and sunny afternoons work a roof hard through the shoulder seasons. Applied as a thick, seamless film, the coating both waterproofs and accommodates the natural movement of the building.

Benefits

Flexes with thermal movement instead of cracking; bridges existing hairline cracks to stop leaks; forms a thick seamless waterproof film; reflects heat to reduce summer cooling demand

Our Process

1) Wash and dry the roof, then repair large cracks and open seams; 2) Reinforce joints and penetrations with embedded fabric; 3) Apply the first elastomeric coat and let it cure; 4) Apply the second coat to reach full membrane thickness

What Affects the Cost

Roof size and the total mil thickness specified; number of coats and any fabric reinforcement; extent of cracks and detail repairs required; elastomeric product grade and elongation rating

Best Time of Year

Apply elastomeric coatings in the warm, dry season so the film can build full thickness and cure before cold, wet weather sets in.
