Yes. We never use high pressure on roofing. Our soft wash process uses low-pressure water combined with specialized cleaning solutions that gently remove moss, algae, and dirt without loosening shingles or voiding your roof warranty.

It’s actually the opposite — cleaning extends roof life. Moss and algae trap moisture and eat away at shingles over time. Removing them helps your roof shed water properly and prevents costly damage.

Because we treat growth at the root, results typically last 2–5 years, depending on your roof type, surrounding trees, and local climate. We can also recommend a maintenance schedule to keep your roof looking its best.

Moss and algae are persistent in the Northwest. That’s why we post-treat your roof to slow regrowth and offer ongoing maintenance options if you’d like. If you ever feel moss is coming back quicker than expected, just give us a call — we’ll make it right. Our goal is to keep your roof healthy and clean for the long run.
