"Jim and Ian came to our house to perform a “Premium Roof Cleaning.” I specifically chose Chinook Services because of their great reputation, fair pricing and that they perform the cleaning process that is recommended by ARMA/GAF. They called ahead, showed up on time, and did a fantastic job. Both of them were respectful, courteous, hardworking and pleasant. They described what they would be doing, how it works and what I should expect. They answered all of my questions and made sure I was aware of the “5 year no new moss” warranty. I’m glad I chose Chinook Services and I wouldn’t hesitate to have them perform more services in the future. I highly recommend them."

"Was able to give a quote over SMS by sending pictures. Came to house, cleaned the roof and gutters as discussed and with very good quality and gave a breakdown of the job done and how to maintain. Recommend and will most likely do cleaning with him again."

Roof Cleaning FAQs, answered by experts

You may become so frustrated with the look of moss on your roof that you contemplate whether to clean or replace your roof. Fortunately, you don’t have to go as far as replacing it. After cleaning the moss, you can use a chemical solution to keep it away. For further protection, trim branches that overhang the roof, as fallen seed pods and leaves on the roof allow moisture to collect, encouraging moss growth. Consider adding zinc-coated flashing to the roof, too. As rain washes across the zinc, it leaves zinc particles behind that inhibit moss growth.

Yes, many services include cleaning as part of the repair process. Confirm with your provider.

You can use a pressure washer to clean a whole host of surfaces. The exterior siding of your house is one of the most popular spots, as well as your driveway, garage floor, patio or deck, and even your outdoor furniture. Just be mindful about the amount of pressure you apply to different materials—concrete can handle a lot more than wood, for example.

Roof cleaning is typically necessary annually, although homes in moist or heavily polluted areas may require more frequent service to prevent buildup.

Inspect annually for damage, clean debris, and reapply sealant to maintain protection.
