No. We do not pressure wash asphalt shingles, and we do not use harsh metal scraping. We remove visible moss by hand using roof-safe nylon tools.

We remove visible moss. Treatment-only services may kill moss but leave dead moss on the roof while weather slowly breaks it loose.

Yes. We can provide before/after photos and a simple description of the work performed.

Usually no, as long as we have safe access.

It depends on scheduling and weather. Most jobs can usually be scheduled within seven days. We also offer 24-hour rush deployment when available. For urgent listing, HOA, or insurance timelines, ask about rush scheduling when you submit your quote request.

Portland metro, including Tigard, Beaverton, Tualatin, Lake Oswego, Sherwood, West Linn, Oregon City, Vancouver, and surrounding areas.

Most roofs should be checked at least once a year in the Portland metro area. How often your roof needs cleaning depends on shade, tree coverage, roof pitch, roof material, and how quickly moss comes back. Some roofs only need occasional moss removal. Others need routine maintenance every year.

Yes. We can clean gutters, remove roofline debris, and recommend a maintenance schedule based on your home. If your gutters are full or roof debris is contributing to moss growth, we can include that in your quote.

Most homes should have gutters cleaned at least once or twice per year. Homes with heavy tree coverage, fir needles, valleys, or gutter guards may need more frequent service. After we see your property, we can recommend a schedule that makes sense for your roofline.

Our visible moss removal is backed by our clean roof guarantee: if the visible result is not right, tell us. We’ll make it right or you don’t pay.

Long-term moss warranties depend on the roof condition and whether moss treatment is included. Manual removal gets the visible moss off now. Treatment helps slow down regrowth. If you want longer-term protection, ask about treatment and warranty options during your quote.

Not always, but it is often recommended. Manual removal gets the visible moss off the roof now. Treatment helps address remaining moss spores and slows regrowth. If your roof has heavy moss, shade, or tree coverage, treatment may be a smart add-on.

Yes. We can remove debris from valleys, rooflines, and areas where needles and leaves collect. Roof debris can trap moisture and contribute to moss growth, so we may recommend debris removal with your roof cleaning.

Yes. We clean tile roofs. Tile roofs are different from asphalt shingle roofs, so the cleaning method depends on the roof condition, tile type, pitch, access, and amount of moss or buildup.

In some cases, tile roofs can be pressure washed carefully, and that can make a major visual difference. We’ll look at the roof first and recommend the safest method for that specific tile roof.

Yes. We clean metal roofs. Metal roofing is usually cleaned differently than asphalt shingles. In many cases, pressure washing is an appropriate method for metal roofs, depending on the roof, coating, pitch, access, and buildup.

Yes. Cedar shake roofs require a different approach. We typically soft clean cedar shake instead of using the same manual removal method we use on asphalt shingles. Cedar is more delicate, so the goal is to clean it without tearing up the wood.

It depends on the roof material.

We do not pressure wash asphalt shingle roofs. For asphalt shingles, we manually remove visible moss using roof-safe nylon tools.

Tile roofs and metal roofs are different. In some cases, careful pressure washing may be appropriate for tile or metal roofing. Cedar shake is typically soft cleaned.

Yes, roof moss can damage asphalt shingles if it is left alone long enough. Moss holds moisture against the roof, grows into the spaces between shingles, and can lift shingle edges over time.

That trapped moisture can make the roof age faster, especially in shaded areas under trees where the roof dries slowly. Moss can also make the roof look older than it is, which can become a problem for buyers, HOAs, insurance companies, or home inspectors.

The sooner visible moss is removed, the easier it usually is to keep the roof looking clean and maintained.

Yes, moss can create problems on tile roofs if it is left alone long enough. Tile itself is durable, but moss can hold moisture, collect debris, grow between tiles, and make the roof harder to drain and maintain.

On tile roofs, the bigger concern is often buildup in the overlaps, valleys, and drainage paths. If moss and debris trap moisture or block water flow, it can contribute to leaks, underlayment issues, and roofline problems over time.

Tile roofs need a different cleaning method than asphalt shingles. In some cases, careful pressure washing can make a big visual difference on tile, depending on the condition of the roof.

Moss and organic buildup can still be a problem on metal roofs, especially in shaded areas under trees. Metal roofs do not absorb water like shingles or cedar, but moss, algae, needles, and leaves can hold moisture against the surface and around seams, fasteners, edges, and drainage areas.

If buildup is ignored, it can contribute to staining, clogged valleys, poor drainage, and unnecessary wear on the roof coating. Metal roofs are usually cleaned differently than asphalt shingles, and pressure washing is often an appropriate method depending on the roof condition, coating, pitch, and access.

Yes, moss can be especially hard on cedar shake roofs. Cedar is a natural wood product, so moss, algae, and debris can hold moisture against the shakes and slow down drying.

When cedar stays wet too long, it can contribute to decay, softening, splitting, and shortened roof life. Cedar shake roofs need a gentler cleaning method than tile or metal. We typically soft clean cedar shake instead of pressure washing it aggressively or scraping it like asphalt shingles.

Some metal roofs can rust, but it depends on the material and condition of the roof.

Steel metal roofs can rust if the protective coating is scratched, worn down, or damaged. Rust is more likely around exposed fasteners, seams, cut edges, scratches, valleys, and areas where moss, leaves, or needles hold moisture against the roof.

Aluminum and copper roofs do not rust the same way steel does, but they can still corrode or develop surface changes over time.

Regular cleaning helps because it removes organic buildup that can trap moisture against the metal and around roof details. If we see rust, coating damage, or loose fasteners while cleaning, we’ll point it out so you know what needs attention.

Most metal roofs should be inspected and cleaned about once a year, especially in the Portland metro area where shade, rain, moss, algae, fir needles, and leaves can build up quickly.

If your metal roof is under trees, near evergreens, or has valleys where debris collects, it may need cleaning or debris removal 2 times per year. The goal is to keep organic buildup from holding moisture against the metal, seams, fasteners, and roof coating.

A clean metal roof drains better, looks better, and makes it easier to spot rust, coating damage, loose fasteners, or other maintenance issues before they get worse.

Most tile roofs should be inspected about once a year, especially in the Portland metro area where moss, algae, leaves, and needles can build up quickly.

If your tile roof is under trees, has valleys, or collects heavy debris, it may need cleaning or roof debris removal 1 to 2 times per year. Tile is durable, but moss and debris can hold moisture, block drainage paths, and create problems around overlaps, valleys, and underlayment.

The right cleaning schedule depends on the tile type, roof pitch, tree coverage, and how fast buildup comes back.

Our tile roof cleaning process starts with a roof condition check. Before we begin cleaning, we look for existing broken, cracked, loose, or damaged tiles and point them out so you know what was already there before work starts.

That way, there is no guessing afterward about whether a tile was already broken or whether it happened during the cleaning.

Tile roofs are durable, but individual tiles can crack or break, especially if they are older, brittle, loose, previously cracked, or walked on incorrectly.

If our crew breaks a tile during cleaning, we fix what we break. Depending on the tile and availability, that may mean replacing the tile, arranging a repair, or working with you on the right solution.

Tile roofs require a different cleaning method than asphalt shingles, metal roofs, or cedar shake. That’s why we inspect the roof first and choose the safest cleaning approach for that specific roof.

Cedar shake roofs usually need to be inspected at least once a year. Because cedar is wood, it is important to keep moss, algae, needles, leaves, and heavy debris from holding moisture against the shakes.

If your cedar roof is shaded or under trees, it may need maintenance 1 to 2 times per year. The goal is not just appearance. The goal is helping the cedar dry out properly so it does not stay wet longer than it should.

Cedar shake roofs need a gentler cleaning method than tile or metal. We typically soft clean cedar shake instead of pressure washing it aggressively.
