Your Roof Deserves More Than a Quick Fix

Moss growth in the Pacific Northwest is not just a cosmetic issue. Left unchecked, it holds moisture against your shingles, accelerates deterioration, and quietly shortens the life of your roof. The good news is that with the right process and the right team, it is completely manageable, and in Columbia City, AA Window, Roof & Gutter Cleaning is the team homeowners trust to get it done right.

Our Professional Roof Moss Removal and Treatment Process

Here is exactly what happens when we show up to service your roof:

  1. We start with a full assessment of moss coverage and overall roof condition
  2. Large moss clumps are gently agitated using a stiff brush to loosen buildup without damaging shingles
  3. A backpack blower is used to clear all loose debris from the roof surface
  4. Downspouts and gutters are inspected and cleared so the drainage system runs free
  5. A professional moss-control treatment is applied to eliminate remaining moss and stop future growth
  6. Complete site cleanup is included before we leave

Why Homeowners Who Care About Their Investment Choose AA Window, Roof & Gutter Cleaning

Protecting your home starts with hiring people who actually know what they are doing. Our technicians are trained on the proper methods for Pacific Northwest roofing conditions, including the perennial moss species that come back year after year if not treated correctly. We do not cut corners, and we do not guess. Every service follows a consistent, proven process so your roof gets the thorough care it needs. When you are on a regular maintenance schedule with us, moss stays manageable, repairs stay minimal, and your roof lasts longer.

Frequently Asked Questions

What can I expect on the day of service?

We’ll call or text when we're on the way to your home in Columbia City. You don’t need to be home for outside work, but we’ll knock on the door to greet you either way. We’ll let you know if we have questions for you or if your home could benefit from any additional services. When finished, we will come to the door to chat before we leave. We can answer any other questions you may have, let you know if we encountered anything unusual during our work, and offer recommendations for a service schedule going forward.

How do you keep from falling off the roof?

We start out by hiring people with a natural talent toward working on uneven surfaces. We hired GRAVITEC to supply and train our technicians in the use of fall protection equipment (ropes and harnesses). In addition, we use high-quality ladders with leg levelers and stabilizer bars and Korkers® brand safety sandals for traction on slippery roofs.

Will it harm my roof if someone walks on it?

Some roofing materials are more fragile than others, and we are very familiar with the different types of material and proper methods for walking on them. The real answer to this is that allowing debris and moss to accumulate on your roof does much more damage than carefully walking on the roof to maintain it. We will certainly assess your roof and determine our ability to work safely, and your roof's ability to sustain our walking on it.

What should I do to prepare for the roof cleaning service?

We will likely need access to your yard waste bin to dispose of the debris from your roof. If you won’t be home, please unlock your gates so we can get all around your home. If you have any pets, it’s best to keep them inside while we work. We may need access to water from your outdoor faucets in order to clean up afterwards, so please make sure the water is turned on. You may want to move your car away from the home, and it’s best to cover your outdoor furniture, particularly if you have fabric cushions.

Should I pressure wash my roof?

No, we advise our clients against pressure washing roofs. Pressure washing often damages composite roofs and reduces the life of the roof because it washes off a layer of the roof.

How do I remove roof moss in an environmentally friendly way?

Choosing the right moss treatment for your specific situation and knowing how to apply the right amount in the right way is the key to environmentally responsible moss removal. Our technicians are trained and licensed to apply moss treatments and will use their expertise to take care of your home and its surroundings while safely and effectively killing the moss on your roof.

How do I remove moss on my roof safely?

By choosing AA Window, Roof & Gutter Cleaning for roof cleaning, you ensure that your roof will be cleaned safely by trained technicians. First, we blow the loose debris from the roof with commercial grade backpack blowers. Next, we use a stiff brush to gently agitate the larger clumps of moss, and then use the blower again. Finally, we clear all the debris from the gutters and downspouts, treat the roof, and do a thorough clean-up.

What is the best way to clean my roof in Columbia City?

AA Window, Roof & Gutter Cleaning offers affordable roof cleaning services to remove moss and debris from roofs in Columbia City. We use a stiff brush on the larger clumps of moss and clear the roof of debris. Our trained and certified technicians will then apply a moss control product to your roof to kill any remaining moss.

AA Window and Gutter employees, in and out of the office, were fantastic getting the windows in my neglected 100 year-old house sparkling clean. Office staff were crystal clear about the process and very helpful. Taylor and Cody know everything about both old and new windows - history, mechanics, weaknesses, etc. And when you look out the windows after they've cleaned them inside and out, it's as though there is no window there!

Thomas did an amazing job. My roof looks great! It doesn’t look like we live in the shire anymore. This company has been great to work with as I had to reschedule multiple times. We will be setting up a regular maintenance so it does not get so bad in the future.
