Moss retains moisture against your shingles, lifting tabs and allowing water beneath. Algae causes UV degradation. Both grow silently — and compound every season you wait to treat them.
Our low-pressure treatment
We never use high pressure on a roof — it can strip protective granules and void your shingle manufacturer's warranty. Our low-pressure soft wash delivers a specialized biocide that kills moss, algae, and lichen at the cellular level. Growth dies and washes away naturally with rain.
Roof types we treat
Ask us about roof rejuvenation. It restores shingle flexibility, helps re-adhere loose granules, and can add several years to a roof that's just getting up there in age. We soft wash first, and the flexibility is guaranteed for 5 years.

Yes. Moss roots lift shingle edges over time, allowing moisture underneath. This leads to rot, leaks, and shortened roof life. Cleaning it early prevents expensive roof repairs down the road.
Not always. If your asphalt shingle roof is aging but doesn't have structural damage, our roof rejuvenation treatment can restore shingle flexibility and help re-adhere loose granules, extending the roof's life by several years. We soft wash the roof first, and flexibility is guaranteed for 5 years.
