Metal Roof Cleaning

What This Service Involves

Metal roofs shed rain well, but the seams, fasteners, and low-slope valleys still collect Northwest moss and algae. Aggressive scrubbing or high pressure can scratch protective coatings and lead to premature rust, so we use finish-safe detergents and low pressure. Our technicians pay special attention to the panel overlaps where organic debris and standing water accumulate. The finished roof looks refreshed and the factory coating stays intact for the long haul.

Benefits

Removes moss and grime without scratching painted or galvanized coatings; Prevents rust by clearing moisture-holding debris from seams; Maintains the reflective properties of the metal surface; Extends the service life of fasteners and panel joints

Our Process

1) Identify the metal type and coating condition; 2) Pre-rinse and protect surrounding surfaces and plants; 3) Apply a coating-safe cleaner to seams and panels; 4) Low-pressure rinse from ridge to eave to prevent water intrusion

What Affects the Cost

Roof panel style and coating type; Amount of moss and oxidation present; Pitch and total metal roof area; Accessibility and number of stories; Presence of rust spots needing extra attention

Best Time of Year

Summer and early autumn provide the dry footing and mild temperatures that make metal roof work safest.
