Roof Washing Services in Walpole, MA

Those dark streaks running down your roof aren't just dirt. They're caused by Gloeocapsa magma, a cyanobacteria that feeds on the limestone filler in asphalt shingles. Left untreated, it spreads every year, holds moisture against the shingle surface, and accelerates deterioration. Moss and lichen cause even more damage by lifting shingle edges and trapping water underneath. Professional roof washing removes these organisms and adds years to your roof's lifespan. Brad handles roof washing across Walpole as part of our professional exterior cleaning for Massachusetts homes.

Dark streaks visible on the roof, especially on north-facing slopes. Green moss growing in shaded areas or between shingle rows. Lichen patches that look like white or gray circles bonded to the surface. Neighbors' roofs have been cleaned and yours is noticeably darker.

Your roof is over 10 years old and has never been washed. Most homeowners think those streaks are just aging. They're not. It's a living organism eating your shingles.

Brad performs all roof washing using the soft wash method. This means low water pressure combined with professional cleaning solutions applied at the roofline and allowed to dwell before a gentle rinse. No high-pressure equipment ever touches your roof.

High pressure voids most shingle warranties and dislodges protective granules. The soft wash approach kills Gloeocapsa magma, moss, and algae spores at the cellular level so they don't return for 2 to 4 years. Brad works safely with proper equipment and takes precautions to protect landscaping, siding, and walkways below the roofline. This service works on asphalt shingles, cedar shake, slate, tile, and metal roofing.

Massachusetts humidity and tree shade create the perfect environment for algae, moss, and lichen growth on roofs. Homes in Walpole, Medfield, and Dover under heavy tree canopies see the fastest growth. North-facing roof slopes are hit hardest because they get the least sun exposure and dry the slowest after rain.

Brad has cleaned roofs across Norfolk County for years and knows which treatment concentrations work best for Massachusetts climate conditions.

Brad uses the manufacturer-recommended soft wash method. No high pressure. No damage. Free estimates. Owner on every job. BBB A+ rated. A lot of contractors will show up with a pressure washer and blast your roof. That's the fastest way to need a new one.
