Roof Disinfecting

What This Service Involves

After moss and algae are cleared, microscopic spores often remain, ready to bloom again in Western Washington's persistently wet conditions. Disinfecting treats the surface at that microbial level, reducing the spore load that drives rapid regrowth on shaded roofs. This step is what separates a roof that stays clean from one that greens over within months of cleaning. It is especially valuable for homes surrounded by dense tree cover where organic growth is a constant battle throughout the Puget Sound area.

Benefits

Kills residual spores left after cleaning; Slows the return of moss and algae; Extends the life of a fresh cleaning; Targets biological growth at the microbial level; Helps shaded, moisture-heavy roofs stay clear longer

Our Process

1) Confirm the roof is cleared of visible growth; 2) Choose a disinfectant safe for the roofing material; 3) Apply the solution evenly across the surface; 4) Allow it to dry and advise on maintenance intervals

What Affects the Cost

Total roof area treated; Amount of prior organic growth; Type of disinfectant applied; Roof material compatibility; Degree of shade and moisture exposure

Best Time of Year

Disinfect during dry weather following a cleaning, ideally in summer, so the solution sets before autumn dampness returns.
