Moss Prevention Treatment in Portland, OR

Moss Busters truck in front of homeWe know the importance of keeping the roof over your head in the best shape possible. As the premiere roof cleaning company in the Portland area, Moss Busters provides the highest quality treatment to keep your roof free of moss and algae.

It’s common, in our temperate Northwest climate, to see moss and algae growth on every roof in the neighborhood. However, leaving moss on your roof can prove detrimental to your shingles. Moss can cause shingles to curl or bow, which can eventually lead to them blowing off entirely in one of our many winter storms. What’s more, bowing shingles can allow excess water to leak into your roof, causing extended water damage. Simple moss prevention treatments can help you to avoid costly repairs.

Preserving the longevity of your roof is paramount, which is why Moss Busters offers roof treatments on either a one-time or on a scheduled basis that can keep moss growth at bay. Preventing moss from forming is easier and more cost-effective than removing it after it has formed.

Our moss treatment services are very effective at preventing unwanted moss growth on your roof, and the value is unmatched in the industry. While some companies may charge high fees for a three-year preventative treatment, their guarantee comes with fine print. With Moss Busters, the preventative treatment is a faction of the cost of some of the competition, and comes with a two-year, no-moss guarantee and no fine print. In some cases our treatment is effective for up to three years. It can be re-applied every two to three years to prevent moss growth, without the need for costly moss removal every few years.

Moss Busters provided excellent service. The bid was reasonable, the service was done right, and the people who did the estimate and work were prompt, friendly, polite, and patient in responding to my concerns. My roof looks great!

The Moss Busters crew showed up on time and did a great job. They used special shoes made to reduce wear and tear on the roof as well as having stabilizers on their ladders so they didn't just lean the ladders on the gutters. I definitely will hire them again.

Excellent job! The crew took the time to move sensitive plants and adequately protected everything while the work was being done. The clean-up was especially well done.

Vitaliy and his crew were very professional and personable from start to finish. They communicated with me throughout the process. It is evident that Moss Busters takes pride in its work all the way through to completion. My roof looks brand new!

Moss Busters always does a great job of spiffing up my home. Not only did my house look great on the outside, but a few weeks later they took care of my parents’ roof as well. They are very professional and do excellent work!

Outstanding. As my husband and I drove up to our house, we were dazzled. It is a 20 year old house, but after Moss Busters' work, it looks like it was built yesterday. And the pride we feel in our home again is priceless.

I would DEFINITELY recommend using Moss Busters. The were prompt with a quote, when I had questions, Vitaliy answered them all. When I scheduled the service, they gave me an exact date and time range AND SHOWED UP!!! Will definitely use again when we need our roof cleaned next year!

It wasn't cheap, but the quality of the work was outstanding, and they got everything done within a couple hours. I have already recommended them to neighbors.

We couldn't be more pleased. We highly recommend Vitaliy to all our friends and neighbors now. We look forward to working with him again in the near future to get our driveway, sidewalk, walkways and patio cleaned.
