Professional Roof Cleaning
Extend your roof's lifespan and restore its appearance with our specialized low-pressure soft wash system. Safe, effective, and designed specifically for roofing materials.
Safe Roof Cleaning Rhode Island & Massachusetts
Rhode Island's humid climate creates the perfect breeding ground for roof algae, moss, and black streaks that damage shingles and destroy curb appeal. Homeowners throughout Providence, Warwick, Cranston, and southeastern Massachusetts face this challenge every year. J&M Power Washing specializes in safe, soft wash roof cleaning that eliminates organic growth without the damaging high pressure used by inexperienced contractors. Our proven system removes those unsightly black streaks caused by gloeocapsa magma algae while protecting your roof's integrity and extending its lifespan by years.
Why Clean Your Roof?
Dark streaks and discoloration on your roof aren't just unsightly—they're caused by algae, moss, and lichen that can actually damage your shingles. These organisms feed on the limestone filler in asphalt shingles, gradually breaking them down and shortening your roof's lifespan.
Our specialized low-pressure soft wash system safely removes these harmful organisms without the damage that high-pressure washing can cause. We use professional-grade, roof-safe cleaning solutions that kill algae and moss at the root.

The Rhode Island Roof Cleaning Challenge
The climate in Rhode Island and southeastern Massachusetts presents unique challenges for homeowners. Our proximity to the ocean brings moisture-laden air inland, while our four distinct seasons create freeze-thaw cycles that accelerate roof deterioration. North-facing roof sections in towns like Smithfield, North Smithfield, and Lincoln stay damp longer, promoting faster algae colonization. Many homeowners in Woonsocket, Cumberland, and Johnston notice their neighbors' roofs developing the same black streaks within months of each other - this isn't coincidence. It's gloeocapsa magma algae spreading through airborne spores across entire neighborhoods. Once established, this bacteria feeds on the limestone filler in asphalt shingles, literally consuming your roof while reducing its reflective properties and increasing cooling costs.
What Are Those Ugly Black Streaks on My Roof?

Those black streaks you see, especially on the north side of your roof, aren't dirt or soot. They are a living algae called Gloeocapsa Magma. This algae is airborne and thrives in moist, shaded areas, feeding on the limestone filler in your asphalt shingles. Left untreated, it not only looks bad but eats away at your shingles, shortening your roof's life.
Our Solution: Our soft wash system uses a 100% biodegradable, eco-friendly solution that eliminates Gloeocapsa Magma at the root, restoring your roof's appearance instantly without damaging the shingles.
The Dangers of Roof Moss in New England
Moss is more than a cosmetic issue. It acts like a sponge, holding onto water. In Rhode Island winters, this trapped moisture freezes and expands, lifting your shingles and causing "frost damage." This can lead to cracks, water leaks, and premature roof failure. Its root system also anchors firmly into the shingle, dislodging the protective granules.
Our Solution: Never use a power washer on moss—it will rip your shingles off. Our soft wash process safely kills the moss, which will then naturally detach and be washed away by the rain, leaving your shingles unharmed.
How Lichen Can Damage Your Shingles
Lichen (the flat, green, or gray "scaly" patches) is a combination of algae and fungus. It has a tough, root-like structure that penetrates the shingle, and it releases acids that break down the asphalt and granules. It is one of the most destructive organisms for your roof.
Our Solution: Our soft wash process is the only way to safely kill lichen. Once treated, it will die, turn white, and be gently rinsed away by the rain over the following weeks, stopping any further damage.
Our Soft Wash Roof Cleaning Process
Unlike pressure washing, which can damage shingles and void warranties, our soft wash roof cleaning system uses low-pressure application of professional-grade biocides specifically formulated for roof cleaning. We apply our cleaning solution at garden-hose pressure, allowing the chemicals to do the work rather than relying on force. This EPA-approved treatment kills algae, moss, and lichen at the root level, preventing regrowth for 2-3 years in most cases. The process is safe for all roofing materials including asphalt shingles, architectural shingles, and even delicate slate or cedar shake roofs found on historic homes throughout Providence and Newport. Our technicians are trained to identify problem areas, adjust treatment concentrations for different roof types, and ensure complete coverage without overspray onto landscaping or painted surfaces. Professional roof cleaning also complements our house washing services for complete exterior home restoration.
