Soft Wash Roof Cleaning

Soft Wash Roof Cleaning in Polk County, FL Safe, No Pressure Method

Those dark black streaks running down your roof are not cosmetic  they are Gloeocapsa Magma, a cyanobacteria that feeds on the limestone filler in asphalt shingles. Left untreated, algae and mold growth shortens your roof’s life, raises energy costs by reducing reflectivity, and can void your roofing warranty. Merritt Pressure Cleaning uses the safe, no pressure soft wash method to eliminate algae, mold, mildew, and lichen  restoring your roof’s appearance and protecting its lifespan.

Why Soft Wash Not Pressure Washing for Roofs

High-pressure washing on a roof is one of the most damaging things you can do to asphalt shingles. Pressure strips granules from the shingle surface  the granules that protect against UV radiation and weathering. Once stripped, shingles age rapidly and fail years ahead of schedule.

Our soft wash method applies no direct high-pressure water to the roof surface. Instead, we apply a professional biodegradable treatment that kills algae, mold, and lichen at the root. The organisms die, rinse away with rain over the following weeks, and the results last far longer than a pressure wash that only blasts away the surface layer.

  • Green algae and moss growth
  • Mildew and mold colonies
  • Lichen — the most stubborn, requires treatment not just rinsing
  • Oxidation and atmospheric staining on tile roofs
  • Roof Types We Clean

  • Asphalt shingle roofs — the most common type in Polk County
  • Concrete and clay tile roofs
  • Metal roofs — standing seam and metal panel
  • Modified bitumen and low-slope flat roofing
  • Frequently Asked Questions

    No that is precisely why we use it. The soft wash method does not strip granules or damage shingle integrity. The cleaning agent does the work; pressure is used only to apply and rinse the treatment at very low levels.

    A properly applied soft wash treatment typically keeps algae and mold at bay for 2–4 years in Florida's climate, depending on tree coverage and shade. Heavily shaded roofs may need retreatment sooner.

    Pressure washing a roof can void certain manufacturer warranties. Soft wash cleaning is compliant with most roofing manufacturer guidelines including GAF, Owens Corning, and CertainTeed. Confirm with your specific warranty documentation if you have concerns.

    We use biodegradable cleaning solutions and thoroughly rinse surrounding landscaping before and after. Your lawn, plants, and flower beds will not be harmed.
