Roof Cleaning &
Roof Moss Removal
Bothell, WA

Our trained experts clean roofs and gutters in Bothell efficiently by using top-of-the-line equipment and state-of-the-art fall protection when removing moss and cleaning your roof. We are always careful of landscaping and protect the integrity of your roof and gutters.

When addressing moss on your roof, our primary goal is to preserve the integrity of your roof by removing the clumpy moss and applying a moss control product to kill any remaining moss. We begin by agitating any large clumps of moss with a stiff brush. Then we blow all the loose debris off the roof with a commercial-grade backpack blower. We clear all the debris from the inside of the gutters and ensure that all the downspouts are clear. We then apply a moss control product to kill any remaining moss and do a thorough clean-up of the surrounding grounds.

Our technicians are trained and certified to apply moss control products. On most roofs, we use a granular, broad-spectrum, peroxide-based algaecide/fungicide called GreenClean Pro. On some roofs we use a liquid moss treatment called Spray & Forget, a biodegradable, non-corrosive, citrus-based cleaner that kills moss and algae. These are the best products we’ve found that are both environmentally responsible and very effective. Neither product contains bleach, lye, acid, phosphates or heavy metals.

Call us at (425) 821-3814 for a phone estimate and schedule a roof cleaning and moss removal and treatment for your home in the Bothell area. Our technician will show up on time and complete the work leaving your roof free of moss, and your gutters and downspouts running clear.

We blow the loose debris from the roof with commercial grade backpack blowers. We use a stiff brush to gently agitate the larger clumps of moss, and then use the blower again. Next, we clear all the debris from the gutters and downspouts, treat the roof, and do a thorough clean-up.

We treat roofs with an environmentally responsible product to kill any remaining moss. It takes about one month for the moss to change color and die. We guarantee that all the moss will die or we will come back and apply another treatment. This process is widely accepted by our customers. 

No, we advise our clients against pressure washing roofs. Pressure washing often damages roofs and reduces the life of the roof because it washes off a layer of the roof. We have pressure washers and use them for cleaning concrete and rinsing decks. We don’t pressure wash roofs. Call (425) 821-3814 for a free estimate!

There was a large amount of moss that came off of the roof and yet I can’t find any of it on our deck or anywhere on the ground. The roof itself also looks great!

I would like to commend Steve for a fantastic job he did cleaning the roof and gutters. He was cheerful, happy to answer any questions I had.


Everything is pristine and the moss killer application is spread out so evenly. I didn’t even realize you had been by to clean the roof, and the clean up was so perfect.

I loved how they are able to give a quote immediately over the phone. The windows look great and the moss has disappeared from the roof!

After the roof and gutter cleaning, I went outside & noticed he had cleaned off my entire porch of debris that has been there for probably more than a year. I was so impressed.

They used a roof cleaning method that takes longer and requires more effort than pressure washing, but which will last longer.
