Photo quotes in about an hour · Same-week scheduling · Licensed & insured
Remove stains. Protect shingles. Extend roof life.
Black streaks and organic growth shorten a roof’s lifespan. Soft-wash cleaning stops streaks and growth before they cost you repairs — gentle on materials, tough on algae, moss, and mildew.
Tile, shingle, metal, and more
The right approach for every roof in Los Angeles: manufacturer-approved soft-wash methods that clean without the damage high pressure can cause to tiles, shingles, and protective coatings.
Soft-wash roof cleaning, approved by manufacturers
Low pressure and measured detergents treat the root cause — the algae and moss itself — not just the surface stain, so results last longer between cleanings.
How our roof cleaning service works
- Inspect — roof material, growth level, and access determine the safest method.
- Protect — landscaping pre-wet, runoff controlled.
- Soft-wash — measured application, proper dwell time, gentle rinse.
- Review — final walk-around with photos.

Please don’t DIY this one
Roof washing is the service where we’ll flatly tell you not to rent a machine: the fall risk is real, wet tile and shingle are treacherous underfoot, and high pressure voids shingle warranties while stripping the granules that protect the roof from UV. If a roof needs cleaning, it needs a crew with the right access equipment and a soft-wash rig — the cost of doing it right is a fraction of the roof it protects.

When to book it
Many roofs go 3–5 years between cleanings, but heavily shaded or coastal homes see algae and moss return faster. Dark streaks aren’t just cosmetic — they absorb heat and shorten shingle life, so treating the growth early protects the roof itself. Pairing with gutter cleaning finishes the whole roofline in one visit.
Where we wash roofs
Soft-wash crews cover the county — including Santa Monica, Northridge, and Los Feliz, where clay tile and older shingle get the gentlest treatment on the truck. Send roof photos for a same-day estimate.
What those black streaks actually are
The dark stains on LA roofs are usually algae, moss, and mildew — organisms, not dirt — which is why blasting them with pressure fails and soft-wash works. The detergent treats the growth itself; the gentle rinse carries it away without stripping granules or cracking tile. That’s also why results last: killing the root beats scrubbing the surface.
Signs it’s time
- Black streaks spreading down from the ridge
- Moss visible along shaded edges and valleys
- Gutters collecting granules or organic debris
- It’s been 3-5 years since the last cleaning
Good to know
- Soft wash is safe for solar-panel-adjacent tile and shingle — the photo above is exactly that job.
- Gutter-edge cleaning can ride along in the same visit to finish the roofline.
- Results last because the growth is killed, not just rinsed — expect years, not months.
- Certificates of insurance are available on request before anyone climbs anything.
Questions
Roof Cleaning FAQs
Will roof cleaning damage my shingles or tiles?
No — Logan's uses soft‑wash methods with low pressure and manufacturer‑approved techniques designed to protect shingles, tiles, and coatings while removing stains and organic growth.
How often should I have my roof cleaned in Los Angeles?
Many roofs benefit from cleaning every 3–5 years, depending on shade, tree cover, and how quickly algae or moss returns; heavily shaded or coastal homes may need more frequent maintenance.
Is the cleaning solution safe for plants and pets?
Biodegradable detergents are used, and crews pre‑wet and protect landscaping, control runoff, and rinse thoroughly to minimize impact on plants and outdoor areas.
Do you clean gutters at the same time?
Yes — gutter‑edge and downspout inlet cleaning can be combined with roof washing to keep water flowing properly and finish the roofline cleanly.
Can roof cleaning help with energy efficiency?
Removing dark streaks and buildup helps the roof reflect more sunlight instead of absorbing heat, which can contribute to more consistent attic and indoor temperatures.
