Roof Cleaning in Harford County and Northern Baltimore County
Gentle soft washing that removes black streaks, moss and lichen from shingle roofs.
Those black streaks on many shingle roofs are algae, and moss and lichen can follow. A roof cleaning uses low-pressure soft washing with a cleaning solution, never high pressure, which can strip the granules off shingles.

When to schedule
Any warm, dry stretch from spring to early fall. Roofs under trees or on the north side of a house collect algae and moss fastest.
Roof cleaning is done in warm, dry weather, usually spring through early fall.
What to ask before you hire
- Do you soft wash, with no high pressure on the shingles?
- Will you protect my landscaping from runoff?
- Do you remove moss by hand, or just treat it?
- Are you insured for roof work?
Questions homeowners ask
Can a pressure washer clean my roof?
It shouldn't be used on shingles. High pressure knocks off the protective granules and can shorten the roof's life. Reputable roof cleaners soft wash.
Is roof cleaning only about looks?
Mostly, though moss holds moisture against shingles and can lift their edges over time, so removing it helps the roof last.
