Algae and moss do not care whether a roof is on a house or a shopping center, and neither does the damage they cause. At Clean Stream Pro Wash, we soft wash shingle, metal, and membrane roofing on commercial and multi-unit buildings across Grand Rapids and West Michigan, extending roof life and keeping properties looking professionally maintained.

Why Wash a Commercial Roof Instead of Replacing It Early?
Algae and moss shorten roof life on commercial buildings exactly the way they do on homes, but the square footage makes the math bigger. Soft washing kills the growth and stops the damage for a small fraction of what replacing a multifamily or retail roof costs.
Clean roofs also run cooler and photograph better for appraisals, insurance renewals, and listings. Insurers increasingly review aerial imagery, and a black-streaked roof invites questions a clean one never raises.
Which Commercial Roof Types Can Be Soft Washed?
Asphalt shingle on multifamily and office buildings, metal roofing on warehouses and retail, and membrane systems each get their own solution and dwell approach, always without damaging pressure. The Asphalt Roofing Manufacturers Association explicitly warns against high-pressure washing on shingles and endorses the solution-based method we use, and metal keeps its finish instead of getting scoured.
We schedule around tenants and business hours, document the work for your records, and can fold roof washing into a full exterior program with building washing. For property managers running multiple sites across Grand Rapids and West Michigan, Clean Stream Pro Wash can put the whole portfolio on one maintenance calendar.
