Silicone Roof Coating

What This Service Involves

Where other coatings soften or break down under constant moisture, high-solids silicone stays intact even where water ponds after a storm, which is a common reality on aging Puget Sound flat roofs. It bonds into a single monolithic layer that resists the ultraviolet and the endless damp cycles our region delivers. Because silicone reflects sunlight, it also helps keep interiors cooler during the increasingly warm stretches of a Northwest summer. Applied in one or two coats over sound substrate, it restores waterproofing without adding significant weight to the structure.

Benefits

Withstands ponding water that would degrade lesser coatings; resists UV breakdown through years of exposure; reflects heat to ease summer cooling loads; renews the roof in a single lightweight monolithic layer

Our Process

1) Clean the roof thoroughly and let it dry completely; 2) Repair seams, blisters, and flashings with compatible materials; 3) Treat penetrations and transitions with silicone detail work; 4) Spray or roll the silicone at spec thickness and verify coverage

What Affects the Cost

Roof area and whether one or two coats are specified; silicone solids content and mil thickness required; extent of ponding areas and detail repairs; access and staging for spray application

Best Time of Year

Apply silicone in the warm, dry summer months when surface temperatures and low humidity let the product cure quickly and bond reliably.
