A clean roof isn’t about appearance ,it’s about protecting your investment. In the Puget Sound, where moss and algae thrive on nine months of sustained moisture, unchecked growth lifts shingles, traps water against decking, and shortens a roof’s life by years. Professional cleaning every 1–2 years is one of the most cost-effective ways to prevent that damage.

Most companies offering this service are pressure-washing businesses. Orca is a licensed roofing contractor — and on your roof, that difference matters.
Our technicians work on Puget Sound roofs year-round — replacing them, repairing them, and cleaning them. That experience shows up in the details: they know that moss damage starts at the north-facing eaves before it’s visible from the ground, that a lifted shingle edge near a valley usually means water is already getting underneath, and that the flashing around a chimney tells you more about a roof’s health than the shingles do.
Every cleaning doubles as a trained visual assessment. If we spot something — a cracked tile, soft decking, failing flashing — we document it with photos and explain what we found before any additional work is ever discussed. No scare tactics, no surprise upsells. Just a straight answer from a contractor who can actually fix what a cleaning company can only point at.
Orca Roofing delivers expert roof cleaning services that focus on protecting your investment.
Our team is trained on every major roofing system — asphalt, tile, cedar shake, composite, and metal. They know how to move safely across each material and what early damage looks like, because they repair and replace these same roofs year-round.
Eco-friendly soft washing that’s tough on moss, gentle on your roof, and safe for landscaping and pets. We never pressure wash shingles or cedar.
If we spot an issue while working, you get photos and a plain explanation before any additional work is discussed. As a licensed contractor we can fix what we find — but the decision is always yours.
$885 per 8-hour day for a one-person crew, $1,770 for two. No vague quotes, no per-square-foot games — you know the cost before we arrive.
Debris, moss, and treatment residue cleared from gutters, walkways, and landscaping before we leave. The only evidence we had there is a clean roof.
The right method depends entirely on what’s on your roof. The wrong one — like pressure washing asphalt shingles — strips protective granules, voids manufacturer warranties, and takes years off a roof’s life. Here’s how we handle each material:
As a professional roof cleaning company, we tailor each job based on moss buildup, roof type, and your expectations. Our process is simple, thorough, and priced clearly at $885 per 8-hour day (1-person crew), or $1770 per 8-hour day (2-person crew):

For $885 – $1770, one or two trained roofing technicians will clean your roof and gutters thoroughly, while also checking for any signs of damage or wear.
If your roof needs more attention, you can book additional days at the same rate to ensure a complete and safe clean.
Professional roof cleaning in the Puget Sound costs $885 per 8-hour day for a one-person crew or $1,770 per day for a two-person crew with Orca Roofing. Most standard residential roofs are completed in a single day; heavy moss buildup, larger homes, or tile roofs may need an additional day at the same rate. Every visit includes gutter cleaning, moss treatment, and a visual assessment by a trained roofing technician.
The safest way to remove moss from a roof is soft washing: a low-pressure application of eco-friendly, biodegradable solutions that kill moss at the root, followed by gentle brushing and rinsing. Pressure washing should never be used on asphalt shingles or cedar — it strips protective granules, gouges wood, and voids most manufacturer warranties. A follow-up treatment slows regrowth between cleanings.
In the Puget Sound region, professional roof cleaning is recommended every 1–2 years. Homes under heavy tree cover or with north-facing roof sections typically need annual attention — those are the areas where we see moss establish first — while open, sun-exposed roofs can often go two years between visits.
Yes. Regular cleaning extends a roof’s lifespan by years and prevents the moss-driven shingle lift and wood rot that lead to expensive repairs. In the Pacific Northwest specifically — where moss and algae grow through nine months of sustained moisture — a cleaning every 1–2 years costs a fraction of the repair work that unchecked growth eventually causes.
Not when done correctly. Damage happens when companies use pressure washers on asphalt or cedar — in our experience, aggressive washing harms more Puget Sound roofs than moss does. Orca uses low-pressure, soft-wash techniques matched to each material, applied by technicians trained on the roofing systems themselves.
Tile roofs require specialized handling because improper foot placement can crack tiles — and matching replacements is difficult on older roofs. The work goes to experienced technicians who know how to distribute weight safely, uses gentle methods designed for tile surfaces, and includes a visual inspection for cracked or displaced tiles. It’s deliberately slower than standard cleaning, and it should be.
Yes. Because Orca technicians are trained roofers, every cleaning doubles as a professional visual assessment — lifted shingles, failing flashing, cracked tiles, soft decking, and early moisture damage. Anything we find is documented with photos and explained plainly before any additional work is discussed.
