Roof Cleaning Without A Pressure Washer Anywhere Near Your Shingles.
Those black streaks aren't dirt. They're Gloeocapsa magma, a blue-green algae eating away at your granules. Sully's soft-washes it off, along with moss, lichen and mold, using zero high pressure on the roof.
How It Works
What Actually Happens On A Roof-Cleaning Visit
Roofs get treated with more care than any other surface on the property, since one bad pass can mean a leak six months later.
Inspect from ground & ladder
Existing damage, loose flashing and problem areas get documented before treatment starts, because that firefighter eye for structural issues doesn't switch off.
Cover & protect landscaping
Plants and gutters below the roofline get pre-wetted or covered so runoff doesn't scorch what's underneath.
Apply soft-wash solution
A low-pressure application targets algae, moss, lichen and mold directly, breaking down growth without disturbing the shingle surface.
Rinse & document
A gentle rinse clears residue, and the finished roof is documented for insurance records along with the satisfaction guarantee.
Why It Matters
Why Roof-Safe Technique Is The Whole Point
Anyone can rent a pressure washer. The difference on a roof is knowing exactly why you wouldn't use one.
Shingles stay intact
High pressure can lift and dislodge asphalt granules and shingle tabs, while soft washing cleans without ever touching the surface with force.
Seals stay sealed
Pressure equipment risks breaking the adhesive sealant bonds between shingles, which is exactly where roof leaks start.
Kills algae at the source
The soft-wash solution is formulated to kill Gloeocapsa magma and moss spores, not just knock the visible streaks off.
Insurance-ready documentation
Before-and-after documentation is provided, useful if your insurer flags roof algae staining at renewal time.
Satisfaction guaranteed
If streaking or growth isn't fully addressed, Sully's comes back to make it right.
A firefighter's judgment call
15+ years reading roofs for hazards on the job translates directly into knowing which roofs need extra care versus a standard pass.
