Moss, lichen, and algae cleared off your shingles with a low-pressure soft wash, and gutters emptied and flushed in the same visit. No high pressure ever touches your roof, and every job is backed by our satisfaction guarantee.
Why Spokane Roofs Grow Moss in the First Place
Spokane sits in exactly the conditions moss loves. From late fall through early spring the Inland Northwest stays cool, gray, and damp, and a roof shaded by ponderosa pines can hold moisture for weeks at a time. North-facing slopes are the worst: they get the least sun, dry out last, and are usually where the first green patches show up.
Pine needles make it worse. They collect along shingle edges and in valleys, hold water against the roof surface, and slowly break down into exactly the organic layer moss wants to root into. If your home sits under trees, the roof is collecting that material every windy day of the year.
Left alone, moss does real damage. It works under the edges of shingles as it thickens, lifting them enough to let wind-driven rain through. Its root-like structures hold moisture against the shingle surface, which accelerates granule loss and shortens the roof's usable life. Cleaning it off is roof maintenance, not cosmetics.
Soft Wash Only: Why We Never Pressure Wash Shingles
Asphalt shingles are surfaced with mineral granules that protect the asphalt underneath from UV. High-pressure water strips those granules off, and once they are gone the shingle ages fast. That is why a pressure washer pointed at a roof can take years off its life in one afternoon.
Our roof process is a soft wash: low pressure, roughly what a garden hose delivers, carrying a cleaning solution that kills the moss, lichen, and algae where they attach. Dead growth releases its grip and comes off with a gentle rinse or breaks down and sheds naturally over the following weeks. The shingles keep their granules, and the growth is actually dead instead of just shaved shorter.
Heavier moss mats are first reduced by hand with soft tools, never metal scrapers, then treated. On delicate or aging roofs we will tell you honestly what the surface can take before any work starts.
Gutter Cleaning: The Other Half of the Job
A clean roof draining into clogged gutters is only half a fix. Gutters full of pine needles and shingle grit overflow at the eaves, and that water pours straight down your siding and pools against the foundation, which is exactly where you do not want it during a Spokane freeze-thaw winter.
Our gutter service clears the full run by hand, bags what comes out, and flushes every downspout until water moves freely. While we are up there we keep an eye out for loose hangers, sagging runs, and separated seams, and we let you know what we see. You get gutters that actually do their job, plus an honest read on their condition.
What to Expect on Service Day
- 1. Free estimate: Tell us your roof type, roughly how big the home is, and what you are seeing. You get a clear price before anything is scheduled.
- 2. Walk-around: We look at the roof and gutters from the ladder before starting and flag anything worth knowing about.
- 3. Treatment and clearing: Moss and algae are treated with the soft-wash solution, heavy mats are reduced by hand, and gutters are cleared and flushed.
- 4. Cleanup: Debris is bagged, walkways are rinsed, and we do a final walk-around with you if you are home.
Most single-story homes are done in a few hours. Steeper rooflines, two-story homes, and heavy moss add time, and you will know that up front from the estimate.
How Often Should a Spokane Roof Be Cleaned?
Once moss is established, most shaded Spokane roofs benefit from a treatment every two to three years, with gutters cleared once or twice a year depending on tree cover. Sunny, open lots can go longer. The best signal is visual: green patches on the north slope, needle piles in the valleys, or gutters overflowing in a normal rain all mean it is time.
