Roof Maintenance, Repair & Cleaning in Clackamas
Most roofs we look at in Clackamas don’t need to be replaced. They need moss pulled off, a valley cleared, flashing resealed, or a section of dry rot cut out before it spreads. That’s the work we’ve built the company around since 2004, and it’s why we get called by people who already have a replacement quote in hand and want a second opinion before they spend twenty thousand dollars.
Clackamas sits east of I-205 along the 212 and 224 corridors, north of the river, and most of it never incorporated. That matters more than it sounds like it should. The housing stock runs from 1970s and 1980s ranches on large lots out toward Carver and Damascus to newer subdivisions along the Sunnyside corridor, and the two age groups fail in completely different ways. The older roofs are usually on their second or third covering with underlayment that’s long past its rating. The newer ones are mostly intact but have never been cleaned, and the moss is doing quiet damage under a canopy of fir that never lets the north slope dry out.
Why do Clackamas roofs grow so much moss?
Shade and standing moisture. Clackamas keeps a heavy tree canopy across much of the older residential area, and any slope that doesn’t get direct afternoon sun stays damp from October through May. Moss roots into the gap under the shingle, lifts the edge, and holds water against the mat. Once that’s happening, the shingle is losing granules every time it rains.
The damage isn’t the moss itself. It’s the water the moss keeps in contact with a surface designed to shed it.
What does roof cleaning cost in Clackamas?
Roof cleaning and moss removal runs $650 to $1,500 for most Clackamas homes. The range depends on square footage, pitch, how much growth has accumulated, and access. A single-story ranch that’s been cleaned in the last few years lands at the low end. A steep two-story that hasn’t been touched in a decade lands at the top.
We clean by hand and treat the surface. We don’t pressure wash asphalt shingles. Pressure washing strips the granule layer, which is the part of the shingle doing the actual work, and it takes years off the roof in an afternoon.
Our Services
Scheduled inspections and tune-ups that catch small problems — loose tabs, worn flashing, early moss growth — before they turn into leaks. This is the core of what we do, and the single best thing a Clackamas homeowner can do for their roof’s lifespan.
Targeted repairs for shingle and tile roofs: resealed flashing, replaced tabs, and leak fixes, done by technicians who work for us directly, not a subcontractor.
For roofs past the point repair can help, we also offer full tear-off replacement, backed by a 14-year labor warranty and Malarkey Certified Pro Contractor installation. See our full roof replacement page for details.
Why Regular Roof Maintenance Matters in Clackamas OR.
Clackamas splits into two housing patterns, and each one hides roof problems in its own way. Out toward Carver and Damascus you get acreage — long driveways, mature fir, and a roofline you might not get a straight look at for months at a stretch. Along Sunnyside and the newer subdivisions the lots are tight, but the roofs are steep, the neighbor’s trees overhang the property line, and the north slope is in shade regardless of how close you park.
Either way the result is the same. Needles collect in the valleys, moss takes hold on the shaded side, gutters pack solid, and the roof stays wet long after the rain stops. None of that shows up from the driveway. It shows up as a stain on a bedroom ceiling two or three winters later.
None of it means more work. It means more consistent attention. A roof on a regular maintenance schedule handles this without incident. A roof left alone develops the kind of problems that are expensive to fix and would have been cheap to prevent.

Roof Cleaning & Moss Removal Costs in Clackamas OR.
Roof cleaning and moss removal typically runs $650 to $1,500+, depending on roof size, pitch, and how much buildup has accumulated. Properties with heavy fir or cedar canopy — common throughout Clackamas area — often fall toward the higher end simply because of how much more debris collects. Larger rural properties with multiple roofed structures (a home plus a shop or barn, for example) are quoted individually. A free inspection gets you an exact number.
Signs Your Clackamas Roof Needs Attention
- Moss or dark streaks concentrated under tree cover or on north-facing slopes
- Needles and debris built up in valleys or gutters, especially after fall
- Granules collecting in gutters or at downspout outlets
- Lifted or curling shingle edges
- Slow-draining gutters after rain — often a sign of a clogged or sagging section
- Any musty smell or visible moisture in the attic
If you’re noticing any of these, a free inspection will tell you exactly what your roof needs — and just as importantly, what it doesn’t.
What Makes Us Different
We’re not a franchise and we don’t subcontract. Every technician who sets foot on your roof is background-checked, trained, and works for us directly — not a crew we hired out for the day. We’ve been doing this in Clackamas since 2004, and our approach has always been the same: tell homeowners the truth about what their roof needs, whether that’s a fix or a full replacement, and let the honesty speak for itself.
That’s earned us 4.9 Rating and 700+ reviews and an A+ BBB rating — and it’s why we’re careful never to recommend more than a roof actually needs. Every visit, from a routine cleaning to a full inspection, includes photo documentation, so you can see exactly what our crew found and what was done, without having to take our word for it.

How much does roof cleaning cost in Clackamas?
How often should a roof under heavy tree cover be cleaned?
Why did a roofer tell me my Clackamas roof needs replacing when it's only 20 years old?
Usually because of what’s growing on it, not what’s wrong with it. A lot of Clackamas sits under heavy fir canopy, and a shaded north slope here can look far worse than its actual condition — moss along the courses, dark streaking, granules in the gutter. From the driveway that reads as a roof at the end of its life.
Get on it and the picture often changes. The shingle mat is usually intact at twenty years even when the surface looks rough, and what’s actually failing is the flashing, a pipe boot, or a valley that’s been holding needles for a decade. Those are repairs, not replacements.
The honest test is whether the covering itself has failed — brittle, curling, losing mat — or whether it’s just dirty and neglected. Worth having someone get up there and show you photos before you commit to a tear-off. If it genuinely needs replacing we’ll tell you, but a shaded, mossy roof is not the same thing as a worn-out one.
What's the difference between roof maintenance and roof repair?
Do you offer full roof replacement in Clackamas?
Are you licensed and insured in Washington?
Yes. We install full asphalt shingle replacements in Clackamas with our own in-house crews, and full replacements carry a 14-year labor warranty. Pricing typically runs $15,000 to $28,000 depending on size, pitch, complexity, and what we find once the old covering comes off.
That said, we quote the repair first. Our business is built around maintenance — cleaning, repair, and preventive work — and a good share of the roofs we’re called out to replace don’t need it yet. If yours does, we’ll show you why with photos and give you a straight number. If it doesn’t, we’ll tell you that instead.
We don’t do overlays. Layering new shingles over the old covering hides the condition of the deck and makes every future repair harder, so if a roof is genuinely done, it comes off first.
