How often should I have my roof cleaned in Oregon?

In the greater Portland area, we recommend a roof cleaning at least once a year - ideally in late spring or early fall. If your home is surrounded by trees or sits on the north side of a hill, twice a year is even better. Moss and debris build up fast in our climate.

Does moss actually damage my roof?

Yes. Moss holds moisture against your shingles, which accelerates wear and can lift shingle edges over time. Left unchecked, it shortens your roof's lifespan and can lead to leaks. Regular cleaning is one of the most cost-effective ways to protect your investment.

Do you offer recurring roof maintenance plans?

We do. We offer both one-time cleanings and recurring maintenance schedules. A lot of our homeowners across the Portland metro set up annual or semi-annual visits so they never have to think about it.

Will pressure washing damage my shingles?

It can - that's why we don't use high-pressure washing on asphalt shingles. We use low-pressure methods and treatments that are effective on moss and algae without stripping granules or voiding your warranty.

How much does roof cleaning cost?

Roof cleaning typically runs between $300 and $800 depending on roof size, pitch, and the amount of buildup. We provide a clear quote before we start. For homes that need both cleaning and minor repairs, we can bundle the work and save you a trip.

Roof Cleaning & Maintenance

Roof Cleaning - Portland Metro

Moss, algae, and debris don't just look bad - they shorten your roof's life. A little maintenance goes a long way in Oregon's wet climate. We keep your roof clean, clear, and lasting longer.

Schedule a Cleaning

Extend Your Roof's Life

Regular cleaning removes the moisture-trapping moss and debris that cause premature aging. A clean roof lasts years longer than a neglected one.

Prevent Costly Repairs

Catching small issues during routine maintenance - a cracked vent boot, a lifted shingle - saves you from expensive repairs down the road.

Protect Your Home's Value

Curb appeal matters, especially in neighborhoods across the Portland metro. A clean roof signals a well-maintained home.

Our Cleaning & Maintenance Process

Thorough, careful, and respectful of your property.

Roof Assessment

Before we touch anything, we inspect your roof to understand the type of growth, buildup, and any underlying issues. We note areas that need extra attention and flag anything that might need repair.

Debris Removal

We clear leaves, branches, pine needles, and anything else that's been collecting up there. Clogged valleys and gutters are one of the biggest causes of premature roof wear in Oregon.

Moss & Algae Treatment

Oregon's damp climate is a moss factory. We treat moss and algae growth with methods that are effective but won't damage your shingles or harm your landscaping.

Gutter Cleanout

While we're up there, we make sure your gutters and downspouts are clear and flowing properly. It's all connected - a clean roof with clogged gutters still causes problems.
