We safely remove black streaks, algae, moss, and lichen from your roof using a low-pressure soft wash — the only method that cleans without damaging your shingles.
Pressure washing a roof destroys it. Soft washing is the method recommended by roofing manufacturers — and the only one we use.
Those dark stains running down your shingles aren't dirt — they're Gloeocapsa Magma, a airborne algae that feeds on limestone in asphalt shingles. Our solution kills it completely, not just masks it.
01Moss and lichen physically lift and crack shingles as they grow, letting water underneath. Left untreated, they cause serious structural damage. Soft washing kills both down to the roots.
02Green or greenish-black patches on shaded north-facing sections of roof are algae thriving in moisture. Common in Minnesota's climate — especially under tree canopy. Our treatment eliminates it fast.
03Because soft washing kills biological growth at the cellular level, results typically last 3–5 years. Pressure washing just rinses the surface — organisms regrow within months.
04We pre-wet and protect surrounding landscaping before applying our solution. Our biodegradable cleaner is safe for lawns, plants, and gutters once rinsed. Your property leaves in the same condition it arrived.
05Get a real estimate before we show up. Our quote tool below walks you through home size and roof pitch — no guesswork, no surprise charges when we're on site.
06A new roof costs $10,000–$20,000. Regular soft washing typically costs a fraction of that — and can add years to the life of your existing shingles. The algae and moss on your roof aren't just cosmetic. They're actively breaking it down.

Yes — soft washing is the only method recommended for asphalt shingles by the Asphalt Roofing Manufacturers Association (ARMA) and most shingle manufacturers. It uses low pressure (similar to a garden hose) combined with a biodegradable cleaning solution that kills biological growth without stripping granules or forcing water under your shingles. High-pressure washing is what causes damage — not soft washing.
The dark stains running down your shingles are caused by Gloeocapsa Magma — a type of airborne cyanobacteria (blue-green algae) that feeds on the limestone filler in asphalt shingles. It spreads from neighbor to neighbor via spores. It's not just an eyesore — it actively consumes your shingles over time and makes your roof absorb more heat. Soft washing kills it at the cellular level.
Most roofs stay clean for 3–5 years after a soft wash. The key difference from pressure washing is that soft washing kills the organisms — it doesn't just rinse the surface. Homes with heavy tree coverage or a lot of shade (north-facing roofs especially) may see regrowth sooner. Adding our post-clean prevention treatment can extend results by an additional year or more.
No — we pre-wet all surrounding landscaping, plants, and lawn areas before we start, and rinse everything again after we're done. Our biodegradable cleaning solution is safe for vegetation once diluted and rinsed. This is standard practice, and we've never had a landscaping issue. If you have particularly sensitive plants you're worried about, just let us know when you book.
No — we work entirely on the exterior so you don't need to be home. Just make sure we have access to all sides of the house and let us know any gate codes. We'll send a quick prep reminder before the appointment and let you know when the job is done. Close all windows and doors the morning of the service.
Pressure washing can void your warranty — soft washing won't. Most major shingle manufacturers (including GAF and CertainTeed) specifically recommend soft washing as the approved cleaning method. Pressure washing, on the other hand, can strip granules and is often listed as a warranty-voiding practice. We always use low-pressure application, so your coverage stays intact.
