Roof Cleaning in Altadena, CA

Yes, we use a low pressure soft wash rather than high pressure spraying, so moss and algae are removed without cracking tile or stripping shingle granules. This is the method most roofing manufacturers recommend for cleaning a roof.

Roof cleaning in Altadena depends on the size, pitch and how much growth is on the roof, so a free instant quote is the most accurate way to price it. We quote upfront and can combine roof washing with gutter cleaning on the same trip.

Those black streaks are usually algae that feeds on the filler in shingles, and they are common on shaded Altadena roofs. Soft washing kills and removes the algae, and our treatment slows how fast it returns.

Most roofs in the Altadena area benefit from cleaning every two to three years, sooner if you have heavy tree cover or north facing slopes that stay damp. Regular cleaning keeps moss from lifting shingles and causing leaks.

Choose a licensed, insured roof cleaning company that soft washes rather than blasts your roof, since high pressure strips shingle granules and cracks tile.
