Moss Removal in Sumas

A Local Owner Who Actually Drives Out To Sumas

We are locally owned, run day to day by Randy Fee, licensed and insured, and Sumas is a regular stop for us rather than some special trip out of the way. Debris comes off the roof first, then bulk moss is brushed away by hand, then the surface is soft washed with a treatment that holds regrowth back. Composition shingles are never pressure blasted, and we take on no repairs, re-roofing or gutter work. Plenty of folks add window cleaning in Sumas as well.

If the roof only needs the needles and leaf litter cleared rather than moss lifted off, that is a smaller and cheaper job — see roof cleaning in Sumas.

Roof moss removal and treatment starts at $699.

All pricing shown is starting pricing. Final pricing depends on the size, condition, accessibility, and scope of work. Free, no-obligation estimates are always provided before work begins. See all starting prices.

Rain, Low Ground And Moss In Sumas

Sumas sits flat and low against the Canadian border, right where the Cascade foothills start to rise, and it catches a lot of rain. Water is a fact of life in this town. The November 2021 flood made that plain enough, and the day to day version is simply a roof that rarely gets much chance to dry out.

Persistent damp is exactly what moss needs. It settles on the shaded slopes, thickens along the shingle courses, and then works its way under the edges until they lift. Water that should shed off the roof sits on the deck instead. That is the slow, expensive kind of damage, and it happens long before anything drips inside.

Booking Moss Removal In Sumas

Three steps from first call to a moss-free roof

Free Estimate

Call or send the form and we will come and look. We will tell you what is actually growing up there, whether it needs the full moss treatment or just a debris clean, and what it will cost — with no obligation and no pressure to book on the spot.

Pick Your Day

Late spring through early autumn is easiest for moss work, but moss grows here all year and we will fit you in whenever suits you. We work around your schedule, we confirm the day, and we turn up when we said we would.

We Do The Rest

Bulk moss comes off by hand or with gentle brushing — never pressure washed. Beds and plants are pre-wetted and tarped first, everything we take off is carried away, and a soft wash treatment goes on so that regrowth comes back slower and thinner.

Moss Removal FAQs For Sumas Homeowners

With this much rain, how often is cleaning needed?

More often than the dry side of the state, less often than people fear. Shade is the deciding factor. A roof that stays wet under trees may want attention every couple of years, while an exposed one can go longer between cleanings.

Do you blast the roof with a pressure washer?

No. Pressure washing composition shingles is a good way to age a roof early, since it strips the granule layer and can force water under the laps. We brush the moss off gently and soft wash instead, which is the method the roofing industry backs.

What keeps the moss from coming straight back?

The soft wash treatment we finish with is designed to slow regrowth, and it buys real time. It is not permanent. Sumas gets a lot of rainfall and moss is persistent, so expect to have the roof cleaned again at some point down the road.

Do you take metal roofs, or only shingles?

Both. Metal roofs around here still collect moss on shaded runs and still trap needles and leaf litter in the valleys. We clear the debris and soft wash the panels, using the same low pressure approach we use on composition.

Can you patch a roof that has moss damage?

No. This company cleans roofs and does not repair them, re-roof them, or work on gutters. If we find lifted or broken shingles while cleaning, we will tell you where, and you can take that to a roofing contractor.

Do you serve homes outside the Sumas town limits?

Yes. Outlying and rural properties are ordinary work for us throughout Whatcom County, and we also cover Skagit County and Oak Harbor. Give us a call at (360) 303-6806 with the address and we will confirm we can reach you.
