Exterior Cleaning
Roof Washing
Low-pressure, manufacturer-appropriate roof cleaning that removes algae, moss, and lichen without compromising roofing material.
Roof washing is available across Los Angeles and Orange County, from tree-shaded canyon properties to coastal homes in Malibu and Laguna Beach.
Service Overview
What it is
Roof washing is a soft-wash process using low pressure and specialized cleaning solutions to eliminate organic growth at the root rather than blasting it off the surface.
Why it matters
Moss and lichen retain moisture, lift tiles and shingles, and degrade roofing material over time. Removing them protects both appearance and the roof system itself.
Our process
- 01Inspect roof condition, pitch, and drainage paths.
- 02Protect landscaping and control runoff.
- 03Apply low-pressure treatment appropriate to the roofing material.
- 04Allow dwell time so organic growth is eliminated, not just displaced.
- 05Rinse gently and clear debris from gutters and valleys.

FAQ
Common questions
Is high pressure ever used on a roof?
No. Roofs are cleaned with low pressure and chemistry designed for the material.
Will the growth come back?
Organic growth returns over time, especially under tree cover. Recurring maintenance keeps it from re-establishing.
Do you protect landscaping?
Yes. Plants and hardscapes are pre-wet, covered where needed, and rinsed after service.
Can roof cleaning extend the life of my roof?
Removing moss, algae, and lichen reduces moisture retention and material degradation, which can help a roof last longer.
What happens if roof algae is left untreated?
Algae and lichen feed on roofing material and trap moisture, which can lead to premature deterioration and lifted shingles or tiles.
Is roof cleaning safe for solar panels?
Solar panels are avoided during roof cleaning. We work around them and can clean panels separately with the proper method.
