Professional Roof Soft Washing Across Montana
Those black streaks on your roof are not dirt — they are Gloeocapsa Magma, a type of algae that feeds on the limestone filler in asphalt shingles. Left untreated, algae shortens shingle life, voids manufacturer warranties, and makes your home look neglected. Moss and lichen cause even more damage by lifting shingles and allowing water infiltration.
406 Pressure Clean uses the ARMA-recommended soft wash method to safely clean roofs. We never use high pressure on shingles — instead we apply a professional-strength cleaning solution that kills algae, moss, and lichen at the root. The roof is then gently rinsed leaving shingles clean and undamaged.
Why Soft Washing Is Critical for Roofs
High pressure damages shingles by stripping protective granules, voiding warranties, and shortening roof life. Our soft wash system cleans just as effectively using chemistry instead of force. Your shingles are fully protected.
Montana Roof Challenges
Montana roofs face algae growth on north-facing slopes, moss buildup in valleys, lichen on older shingles, and debris accumulation from surrounding trees. Our cleaning treatments include preventive treatments to slow future regrowth.
Serving Billings, Bozeman, Great Falls, Miles City, and all of Montana.
