Moss, algae, lichen and black streaks killed and cleared with low-pressure soft washing — the shingle-safe method that adds years to a mid-life roof.
Before we price Roof Cleaning Soft-Wash Only, we look at pipe boots, the starter strip and step flashing — the details that decide how long the work holds. You get a photographed assessment and a written scope with no obligation, and if the cause traces to a storm we document it for your carrier. Licensed and insured in Ohio, Pennsylvania and New York.

No. Pressure washing strips the granules that protect asphalt shingles from ultraviolet damage and can drive water under the courses, which turns a cosmetic problem into a structural one. Soft washing uses low pressure with a cleaning solution that kills the organism and lets rain rinse the roof gradually. Related: roof moss removal and roof algae removal.

Moss and lichen root into the granule surface and hold water against it through every freeze-thaw cycle; the black streaks are algae feeding on the limestone in your shingles. Left alone, they shave years off a roof. Our soft wash applies a cleaning solution at low pressure that kills the growth at the root — it browns, dies, and rinses away with the weather.
A pressure washer strips the granules that protect shingles from UV — it makes the roof look clean by removing its armor, taking years off its life in an afternoon. Soft washing gets the same visual result chemically, at rinse-level pressure. If someone quotes you a pressure-washed roof, the cheap price includes a hidden cost.




Soft-wash pricing scales with roof size and staining — current rates live at roofgutternow.com/services, and a photo of your roof usually gets you a same-day exact quote.
The treatment kills it immediately; heavy moss browns and releases over the following weeks as weather rinses it off. Black streaks typically clear much faster.
We pre-wet and rinse landscaping around the house and control overspray. It’s part of the process, not an afterthought.
In our climate, every 3–5 years for shaded or north-facing roofs prone to growth — sooner if you see moss returning at the edges.
It’s the only washing safe for any roof — no pressure means no granule loss, which matters more as shingles age.
Typically years — treated surfaces resist recolonization, and shade management stretches the interval further.
Treatment kills lichen at the root; the crusts release gradually with weather rather than being torn off shingle surfaces.
