Roof Cleaning

What This Service Involves

Constant Pacific Northwest moisture turns north-facing roof slopes into a haven for moss and black algae within just a few seasons. Our crews assess the roofing material first, then apply a low-pressure soft wash treatment that kills growth at the root rather than blasting granules loose. Runoff is controlled and surrounding plants are rinsed and protected throughout the visit. The result is a clean, streak-free roof that sheds rain the way it was designed to.

Benefits

Extends the usable life of your roofing by removing moisture-trapping growth; Restores curb appeal without abrasive high pressure; Protects gutters and downspouts from dislodged moss debris; Reduces the chance of costly leaks caused by lifted or degraded shingles

Our Process

1) Inspect the roof material and identify moss, algae, and problem areas; 2) Shield landscaping and saturate nearby plants with water; 3) Apply a low-pressure biocide treatment and allow proper dwell time; 4) Gently rinse and clear loosened debris from the roof and gutters

What Affects the Cost

Total roof square footage and number of stories; Steepness and accessibility of the roof pitch; Severity of moss, lichen, and algae coverage; Roofing material type such as composition, cedar, or metal; Amount of surrounding tree cover contributing debris

Best Time of Year
