If you live in the Portland or Vancouver area, then you’re familiar with cloudy and rainy days. Unfortunately, this is exactly the type of weather that moss and fungi need to grow and overtake your roof.
It’s extremely important to maintain your roof and keep moss at bay. Moss soaks up moisture, and in a wet climate like the Pacific Northwest, a mossy roof means a perpetually wet roof. Not only does a mossy roof look bad, it also:
- Damages your shingles
- Hurts the integrity of your roof
- Allows water to leak into your home
- Encourages bacteria and mold growth
- Creates thin spots and holes in your roof
Whether you notice a small amount of moss on your roof or are dealing with a roof completely overgrown with moss, we can help remove and prevent moss from growing on your roof!

Roof Moss Removal Services
At Northwest Roof Maintenance, we offer a proven moss removal treatment to homeowners in the Portland and Vancouver area. Our process uses a combination of compressed air and soft brushing to clear away roof moss.
- First, we’ll gently brush away the moss by hand, freeing it from your shingles.
- Using air, we’ll blow the loosened moss and debris out from between the shingles/tiles of your roof.
- Lastly, we’ll clean your gutters after every roof cleaning and always do a full clean-up of the area and check in with you to make sure you’re satisfied with the results.
Our moss removal process does not damage your shingles. Removing moss will help prolong the integrity of your roof.
Roof Moss Preventative Treatments
We use tried and true preventative treatments to keep moss and other rot-causing organisms away from your roof. Our moss prevention treatments cover the entire roof, ensuring moss has nowhere to grow.
Cleaning of Tile and Composition Roofs
On tile and composition roofs, we use a water-based zinc treatment to kill the moss. This treatment can take up to a few weeks to fully kill the moss. The moss on your roof will slowly turn a yellowish-brown color and eventually turn black. Our liquid spray soaks into your shingles, ensuring that new moss doesn’t take root.

Frequently Asked Questions
Q. Do You Offer a Warranty on Your Moss Prevention Services?
A. Yes, we do provide a warranty on our treatments. If your first application isn’t effective, we’ll come back within the warranty period at no cost to you!
Q. Can You Apply a Moss Prevention Treatment If It’s Raining?
A. Our moss prevention treatment can be applied even in a light drizzle. It’s the optimal treatment for our rainy Portland and Vancouver weather. We always follow this general rule: the treatment can be applied unless it is raining hard enough for water to be running down the roof.
Q. What Is the White Residue on My Roof?
A. It’s not uncommon for a white residue to appear on your roof in the few days following a moss prevention treatment. This residue is caused by a high concentration of zinc and is completely harmless to your roof. It will rinse away with the next heavy rain.
Q. Can You Remove Moss from Cement Tile Roofs?
A. On cement tile roofs a high-pressure wash may be necessary to free moss, mildew, lichen, and algae. This process can accelerate the deterioration of your roof, so we only use this method in extreme cases, or as required by HOA regulations.
Northwest Roof Maintenance came out to seal a leaking skylight, replace some vent boots, and do an all over moss removal and treatment. They were on time, courteous, and did the job for a great price. Will definitely use them again!
