ROOF CLEANING FOR RESIDENTIAL AND COMMERCIAL PROPERTIES
OUR ROOF CLEANING PROCESS
We never use high pressure on roofs — it voids warranties and damages shingles. Instead, we use a soft wash system: low-pressure water combined with specialized cleaning solutions that kill moss, algae, lichen, and black streaks at the root. First, we inspect your roof from the ground and (when safe) up close, noting the roofing material, pitch, and problem areas. In York's humid summers, north-facing slopes often develop thick moss; in Lancaster, we see a lot of black algae streaks (gloeocapsa magma) on asphalt shingles. We protect your landscaping with tarps and pre-wet plants, then apply our cleaning solution and let it dwell. After a gentle rinse, your roof looks years younger — and the treatment keeps working to prevent regrowth.
SIGNS YOUR ROOF NEEDS CLEANING
Black streaks running down your shingles? That's algae feeding on the limestone filler in asphalt shingles — common on homes in Harrisburg and Mechanicsburg. Green moss or white lichen patches hold moisture against your roof, accelerating wear and potentially lifting shingles. If your roof looks blotchy, discolored, or has visible growth, it's time for a cleaning. Many homeowners in Hanover and Carlisle don't realize their 'aging' roof is actually just dirty — a professional soft wash can restore its appearance and add years to its life. We also clean roofs before real estate photos or after nearby construction leaves dust and debris.
ROOF CLEANING PRICING FACTORS
Roof cleaning cost depends on roof size, pitch, material, and soil level. A single-story ranch in York with light algae costs less than a steep three-story Victorian in Lancaster with heavy moss. Asphalt shingles are the most common and straightforward; tile, slate, or metal roofs may require different techniques. We also consider accessibility — can we safely reach all slopes? — and whether gutter cleaning should be bundled (it often should). You'll get an upfront quote with no surprises.

Yes. We use a professional soft washing method designed specifically for roofing materials. This low-pressure process safely removes algae, moss, and stains without damaging shingles, tiles, or flashing.
Results typically last 2–5 years depending on weather conditions, tree coverage, and roof orientation. Our cleaning removes the root cause of black streaks (algae), helping keep your roof looking clean longer than surface rinsing alone.
