Roof cleaning: what it does and why it matters
If your roof has black streaks, greenish patches, moss, lichen, or a generally dingy look, those are signs of biological buildup that can shorten the life of shingles, tile, or metal roofing and make your home look older than it is. Professional roof cleaning removes that buildup safely and effectively using soft washing at very low-pressure so the roof is cleaned without harsh pressure that can shorten roof life.
What we do
- Full roof inspection first: every roof is inspected by an in-house certified residential roof inspector before cleaning to identify vulnerable areas and choose the safest approach.
- Soft washing at very low pressure: we use soft washing methods only, not high-pressure techniques, to remove algae, black streaks, moss, lichen, and other buildup from shingles, tile, or metal roofing.
- Safe cleanup and follow-up check: after cleaning we inspect the roof again and make sure runoff and landscaping are protected.
Why soft washing matters
- Gentle on roofing materials: low-pressure soft washing removes biological growth without the abrasive forces that can loosen granules, lift shingles, or damage tiles.
- Targets the root cause: professional soft wash solutions break down the organisms causing black streaks and moss, giving longer-lasting results than surface-only rinses.
- Helps prevent secondary problems: removing moss and heavy growth reduces the risk of moisture trapping and downstream issues like gutter clogging and roof rot.
Signs you should schedule a professional roof cleaning
- Visible black streaks or discolored patches across shingles
- Patches of moss or lichen growth
- Roof looks consistently darker than neighboring homes in your community
- Noticeable buildup that hasn’t gone away after normal weather events
