Waterproof Roof Coating

What This Service Involves

Flat and low-slope roofs in Western Washington live under water far longer than roofs in drier climates, and every seam and fastener is a potential entry point. A fluid-applied waterproof coating flows into those details and cures into one continuous membrane with no laps for water to sneak beneath. Applied over a properly cleaned and primed surface, it extends the life of an aging roof without the disruption and cost of a full tear-off. For owners tired of chasing seam leaks each winter, it is often the most practical path to a dry building.

Benefits

Creates a seamless barrier with no laps or fasteners for water to find; extends roof life and defers a costly full replacement; installs with far less disruption than a tear-off; formulated to endure prolonged Northwest wetting

Our Process

1) Pressure wash and dry the roof, then repair open seams and flashings; 2) Prime the surface to promote adhesion in damp conditions; 3) Reinforce seams and penetrations with embedded fabric; 4) Apply the waterproof topcoat at the specified thickness and inspect the cure

What Affects the Cost

Total square footage and the coating thickness specified; condition of the existing roof and how much prep and repair it needs; number of penetrations and seams requiring reinforcement; product system selected and its warranty tier

Best Time of Year

Plan coating work for the dry window from June through September, since these systems need consecutive rain-free days to cure to full waterproof strength.
