Roof cleaning, done without wrecking the shingles.
Those black streaks running down a Maine roof are algae, and the green fuzz along the north slope is moss holding water against your shingles. Both shorten the life of a roof, and both come off — as long as whoever cleans it knows not to blast it with a pressure washer.
What roof cleaning covers
- Soft-wash treatment that kills algae and moss without stripping the granules off asphalt shingles
- Black streak removal — the Gloeocapsa stains you see on almost every roof after a few Maine summers
- Moss clearing on shaded and north-facing slopes, where it grows thickest
- Cedar shake and shingle roofs, cleaned at pressures that won't split the wood
- Debris removal from valleys and around chimneys, where wet leaves sit and rot
- A look at the gutters while we're up there, so you know what you're dealing with
Why pressure washing is the wrong tool
A pressure washer will get a roof clean and take years off it at the same time — it lifts granules off asphalt and drives water up under the shingles. We use a low-pressure soft wash with a cleaning solution instead: it kills the growth at the root, rinses gently, and keeps working for weeks after we leave. The roof stays clean longer, and the warranty stays intact.
When to have it done
Most Southern Maine homes need it every three to five years, sooner if the house sits under trees or close to the water. Late spring through early fall is ideal. If you're seeing streaks from the street, or moss thick enough to hold a fingerprint, it's time.
