Roof Moss Removal Spokane
Professional Roof Moss Removal
Spokane homeowners are no strangers to the challenges that moss growth can bring to their rooftops. With shaded yards, seasonal moisture, and tall surrounding trees, moss often finds the perfect environment to grow—and once it starts, it does not stop. Moss may appear harmless at first, but it can cause real damage if left untreated.
Spokane Pressure Washing specializes in effective moss treatment solutions that stop moss in its tracks. Our process goes far beyond the temporary fixes offered by other companies. While some rely on zinc treatments that only make the moss sick, our treatment kills it completely—including the spores and seedlings. We stand by our product and back it with a three-year warranty. If moss grows back within that time, we return and retreat the area at no cost.
Many homeowners make the mistake of trying to remove moss with pressure washing. This method may seem quick, but it often causes damage to the roof by lifting shingles or removing protective granules. Once that happens, the roof becomes more vulnerable to leaks, rot, and costly repairs. That is why we use a soft treatment method designed to clean without causing harm.
Moss is more than a visual issue. When left to grow, it holds moisture against your shingles, slowly breaking them down and creating entry points for water. Over time, this can lead to major structural problems. Algae often appears alongside moss, embedding itself into the pores of your roof and giving moss a place to take hold. These organisms thrive in the shaded, damp parts of your roof—especially the north-facing side that gets little sun.
The key to avoiding expensive repairs is early detection and treatment. Having your roof inspected once a year can help catch moss growth before it spreads. Preventative moss treatments are far more affordable and effective than repairing a water-damaged roof.
Spokane Pressure Washing is proud to provide roof moss removal services that are safe, effective, and guaranteed. Whether your roof is showing early signs of moss or already needs treatment, our team is ready to help you protect your home from the top down.

How Can Moss Damage your Spokane Roof
Roof moss is one of the most overlooked threats to residential properties in Spokane. With our climate, it is easy for moss to thrive in damp, shaded areas, especially on roofs with northern exposure or limited sun. While moss might seem like a harmless layer of green, it can quietly damage your roof from the outside in.
At Spokane Pressure Washing, we treat moss differently. Most companies use zinc-based solutions that only weaken the moss. It might look like it is gone, but the roots remain, and the moss eventually returns. That is not how we do things. We use a targeted cleanser that kills moss completely—root, seedling, and all.
Because we know our process works, we offer a three-year warranty. If moss comes back within that time, we return and treat it again at no cost. You will not find many moss treatment companies in Spokane with that kind of guarantee, and the reason is simple: most do not get to the root of the issue.
Pressure washing moss may seem like a fast solution, but it can be one of the worst things for your roof. The force of the water can strip shingles, cause leaks, and reduce your roof’s lifespan. Our team uses a gentle but effective process that keeps your roof intact while removing all signs of moss and algae.
Beyond the damage to your shingles, moss traps moisture, allowing water to penetrate your roof system. It can rot the wood underneath, degrade insulation, and even lead to mold problems in your attic. Algae can also settle into the surface of your shingles, feeding the moss and lichen that follow.
Prevention is always better than repair. By scheduling a roof inspection and treatment once a year, you can avoid expensive damage and extend the life of your roof. Moss problems usually begin in areas you can’t see from the ground, so it is best to have a trained professional inspect and treat the entire surface.
