Those dark streaks running down your shingles aren't just cosmetic — they're a living organism that feeds on your roof's limestone filler, retains moisture, and shortens shingle life by years. A garden hose won't kill it. Pressure washing will destroy your shingles. DJ at Mechanical Magic uses a zero-pressure soft wash that kills the algae at the root and restores your roof's original color — safely, without dislodging a single granule.
Black streaks on your roof? It's algae — and it's eating your shingles. DJ kills it at the root with zero-pressure soft wash. No damage.
Canton's warm, humid climate is paradise for Gloeocapsa magma — the blue-green algae responsible for those ugly black streaks cascading down your roof. This isn't surface dirt that washes off in a rainstorm. It's a living colony that feeds on the limestone filler in your asphalt shingles, retains moisture against the surface, and spreads across your entire roof via airborne spores. Every year you wait, it gets worse.
A dirty roof isn't just ugly — it's expensive. Algae-covered shingles hold more heat (increasing cooling bills), deteriorate faster (shortening roof life by 5-10 years), and tank your home's curb appeal. Insurance companies have denied renewal on heavily stained roofs. HOAs issue violations. And potential buyers assume the roof needs replacing — knocking $10,000+ off your home's perceived value. Professional soft wash cleaning solves all of it in a single afternoon.
Same roof. Same shingles. No replacement needed — just proper soft wash treatment that kills the growth and reveals the original color still there.
Zero pressure. Manufacturer-approved method. Kills algae at the root — doesn't just rinse it off the surface.
All plants, bushes, and landscaping below the roofline are pre-soaked with water and covered where necessary. Gutters and downspouts are checked. We protect your property before a single drop of solution touches the roof.
A sodium hypochlorite-based cleaning solution is applied at low volume across the entire roof surface using specialized equipment. This kills Gloeocapsa magma algae, moss, and lichen at the cellular level — not just the surface.
The solution dwells on the roof for a calibrated period, penetrating deep into algae colonies and moss root systems. This is where the magic happens — the chemistry does all the work, not pressure. The growth dies completely.
A gentle low-pressure rinse removes the dead organic material and cleaning solution. Landscaping gets a final thorough rinse. Your roof emerges clean, protected, and restored to its original color — with years added back to its lifespan.
Every major shingle manufacturer — GAF, CertainTeed, Owens Corning — explicitly warns against pressure washing roofs. High-pressure water blasts off the protective granules embedded in asphalt shingles. Those granules are your roof's UV protection, fire rating, and waterproofing layer. Remove them, and you've just taken 10+ years off your roof's life while potentially voiding your warranty.
DJ's soft wash method uses zero mechanical pressure on your shingles. The cleaning solution does 100% of the work chemically — killing algae, moss, and lichen at the root. The rinse is at garden-hose pressure or lower. Your shingles keep every single granule, your warranty stays intact, and the algae doesn't come back for years because it was killed at the root — not just rinsed off the surface.
No hidden fees. No bait-and-switch. DJ quotes you a number and that's what you pay — period.

"DJ did an amazing job on a very large, dirty driveway after some major backyard renovations! The fence was pretty dirty and had a lot of mildew that he took care of. Great communication, professional and did great work. As a contractor, this is probably more important to me than most homeowners. Will continue to use him on future projects!"
