How Can We Help You?

Roof Cleaning

Extend your roof's life with a soft wash.

Your roof is an essential investment that requires regular maintenance. Most roof washes cost less than 5% of the cost of a new roof and will ensure its optimal performance. Regular cleaning will also ensure that your gutters flow correctly and will keep dirty water off your siding.

We provide a safe soft wash to all roofs, including metal, asphalt, cedar, slate and tile. We use chemical solutions adapted specifically for your roof and follow cleaning guidelines backed by ARMA (Asphalt Roof Manufacturers Association).

Don't void your roof's warranty with a pressure washer! High pressure will always cause damage to your composite shingle roof. You can rely on us for a safe solution.

Prevent moss growth for two years

Taking care of your roof is an important task that is often overlooked. Staying up on roof washes ensures your roof will be living its best and longest life. If you wait until you see moss growing, the damage has already been done. Every home is different, and the intervals between roof washes will vary based on location. Some clients in more wooded areas such as Glacier and Sudden Valley need their roofs washed and cleaned every year, while others in farmland such as Lynden and Ferndale may only need their roofs washed every three to four years.

Why is there still moss on my roof?

The moss on your roof has been killed but is still rooted between the shingles. It is important not to remove this growth with force to protect your roof and home. Removing moss with a pressure washer or wire brush will always cause damage to your roof, which does more harm than good. Moss will take one to six months to loosen its grip and start falling off your roof. Steeper roofs will clean easier with weather and gravity, while roofs with a lower pitch may require a light brush and leaf blow down the road.

I never had such clean windows! I always unsuccessfully did my windows myself, second story windows and screens suffered under my watch. I called Mt. Baker Window Cleaning and they did a fantastic job. Very professional.

Mt. Baker's Team.

Our Community Involvement

We are dedicated to our clients, our employees, and our community. Bellingham is primarily a community of outdoor recreators and appreciators of nature which leads us to the start of our company. Mt. Baker Window Cleaning Co. was founded because our CEO was looking for a job that would allow him to spend more time outdoors and fund his love for snowboarding, mountain biking, and snowmobiling. Our workplace culture has since attracted climbers, skiers, white water kayakers, mountaineers, wilderness first responders, and others. When the time came to donate back to our community, we asked our clients whom they would like us to support. We heard back from the Baker 542 Ride team and thought they would be a perfect fit! All of us here at Mt. Baker Window Cleaning Co. are working to do the things we love, and now we get to help more people in our community get outside to enjoy this incredible place we call home.
