Roof Washing
What Is Professional Roof Cleaning?
Those dark black streaks running down your roof aren't dirt — they're a living bacteria called Gloeocapsa Magma that feeds on the limestone filler in your asphalt shingles. Left untreated, it spreads across your entire roof, degrades your shingles, and can shorten your roof's lifespan by years. Moss and lichen cause similar damage by lifting and cracking shingles over time.
Professional roof cleaning using the soft wash method kills all biological growth at the root — not just on the surface — and rinses it away safely without voiding your warranty or damaging a single shingle. It's the only method recommended by the ARMA (Asphalt Roofing Manufacturers Association).
⚠️ Never let a contractor pressure wash your roof. High pressure strips granules, voids warranties, and causes leaks. Soft washing is the only safe method — and it's all we use.
Why It Matters
Benefits of Professional Roof Cleaning
A dirty roof isn't just an eyesore, it's actively destroying one of the most expensive parts of your home.
Extend Your Roof's Life
Algae, moss and lichen physically break down shingle material over time. Regular cleaning can add 5–10 years to your roof's lifespan and prevent a $15,000+ replacement.
Maintain Your Warranty
Most shingle warranties require proper maintenance including periodic cleaning. Neglecting biological growth buildup can void your warranty when you need it most.
Avoid Costly Replacement
Homeowners who clean vs. replace save thousands. A professional roof cleaning costs a fraction of what a new roof does — and delivers dramatic results.
Instant Curb Appeal
Your roof is one of the largest visual elements of your home. Removing black streaks and green growth transforms the entire look of your property immediately.
Prevent Leaks & Damage
Moss and lichen lift and crack shingles over time, allowing water to penetrate your roof deck. Cleaning prevents this damage before it becomes a leak — or a structural issue.

FAQs
Roof Washing Frequently Asked Questions
Everything homeowners ask before booking a roof cleaning in Central Minnesota
Those black streaks are caused by a bacteria called Gloeocapsa Magma, which feeds on the limestone filler in asphalt shingles. It spreads via wind and rain and will eventually cover your entire roof if untreated. Over time it degrades your shingles, reduces your roof's ability to reflect UV light (increasing cooling costs), and significantly shortens its lifespan. The good news is it's completely removable with professional soft washing.
No — soft washing is the only roof cleaning method that will not damage your shingles. It uses very low water pressure combined with a professional cleaning solution. The solution does all the work, breaking down and killing the biological growth without any physical force on your shingles. It is the method recommended by the Asphalt Roofing Manufacturers Association (ARMA) and most shingle warranty policies.
In Minnesota's climate, soft wash roof cleaning results typically last 2–4 years. The humid summers and shaded areas can accelerate regrowth, particularly on north-facing slopes. Our treatment includes an algae inhibitor that slows regrowth significantly. Annual inspections and a touch-up cleaning every 2–3 years keeps your roof consistently clean for a fraction of what one replacement would cost.
Yes — we adjust our solution concentration and application method based on your roof material. Cedar shake requires a gentler solution to avoid drying out the wood, while metal roofs need solutions that prevent streaking and won't corrode the finish. We assess your specific roofing material before every job and never apply a one-size-fits-all approach.
Roof cleaning pricing depends on the square footage of your roof, its pitch, and the level of algae, moss, or lichen growth. Most single-family homes in Central Minnesota range from $300–$600. Compare that to a full roof replacement starting at $10,000–$20,000 — professional cleaning is one of the best-value investments a homeowner can make.
