Frequently Asked Question
Do you offer ongoing maintenance services?
Yes! After an initial roof cleaning to remove any moss, algae, and other growth we can provide recurring roof blowing, gutter cleaning, and moss treatment plans to keep your roof clean and functional year-round—without the wear and tear of frequent power washing. These plans help clients avoid major issues and extend the time between cleanings.

Of course we take every precaution to clean carefully preventing leakage in the cleaning process.

How do you clean older wood roof shingles, shake wood shingles or delicate roofs?
We can clean delicate roofs with a commercial air compressor to remove moss, algae, mildew, dirt, debris, grime, etc. as possible from the roof. We then perform a roof moss treatment to help prevent moss from growing back.
How often should a commercial roof be cleaned?
Instead of repeat roof cleaning, we recommend routine roof blowing, gutter cleaning, and moss inhibitor treatments to prevent buildup and extend your roof’s lifespan. Once the moss, algae, mildew, dirt, debris, grime, etc. has been removed and moss inhibitor has been applied, annual application of the the moss inhibitor should prevent the need for additional roof cleaning.
