Roof Washing & Soft Washing in Nashville, TN
Those black streaks on a roof are algae, not just dirt, and they spread over time if left alone. We use a low-pressure soft-wash treatment designed for roofing material, so the algae and moss come off without stripping granules or damaging shingles the way high-pressure washing can.
What's included
- Low-pressure soft-wash roof treatment
- Black streak and algae removal
- Moss treatment on shaded roof sections
- Gutter exterior rinse as part of the visit
- Shingle-safe cleaning solution, no harsh scrubbing

Black streaking, visible moss, or wanting to protect your roof's lifespan before a full replacement is needed are the top reasons to call.
Why it's worth it
- Improves curb appeal without a full roof replacement
- Low-pressure method protects shingles and their granule coating
- Removing algae and moss early helps extend your roof's life

Roof Washing FAQs
Is roof washing safe for shingles?
Yes, when it's done the right way. We use a soft-wash, low-pressure method built for roofing, not a high-pressure wand that can strip granules.
What causes the black streaks on my roof?
It's typically a type of algae that spreads across shingles over time, especially in humid climates like Middle Tennessee.
How often does a roof need this?
Most roofs do well with a soft wash every couple of years, though it depends on shade, humidity, and how quickly streaking returns.
