How Often Should You Clean Your Roof and Gutters? A PNW Homeowner’s Guide
04.15.25
Living in the lush, green beauty of the Pacific Northwest has its perks—but it also means your home’s roof and gutters are constantly under attack from moss, leaves, pine needles, and heavy rain. Regular maintenance isn’t just about curb appeal—it’s about preventing costly damage down the line.
So how often should you actually clean your roof and gutters? Let’s break it down.
📅 General Recommendations
While every home is different, here’s a helpful rule of thumb:
| Type of Maintenance | Recommended Frequency | Best Time of Year |
|---|---|---|
| Gutter Cleaning | 2x per year | Late fall & early spring |
| Roof Debris Removal | 1–2x per year | Spring and/or late fall |
| Moss Treatment Application | 1x per year (up to 2x in heavy moss zones) | Spring or early fall |
| Full Roof Cleaning (soft wash) | Every 2–3 years (or as needed) | Spring or summer |
🌲 Factors That Affect Your Schedule
Depending on your home’s unique setup, you might need more frequent service:
1. Tree Coverage
If your roof is shaded by overhanging trees (especially evergreens like firs and cedars), you’ll want to clean more often. Trees drop needles, sap, seeds, and branches—clogging gutters and feeding moss growth.
Tip: Homes under tree cover should aim for roof and gutter service 2–3 times per year.
2. Roof Pitch and Material
Steep-pitched roofs shed debris more easily than low-slope or flat roofs. Asphalt shingles are more prone to moss growth than metal or tile. Knowing your roof type helps determine your needs.
3. Your Neighborhood’s Climate
In the greater Seattle area (and up into the Puget Sound and Portland regions), high rainfall and mild winters create perfect conditions for moss. Drier areas may not need moss inhibitor applications as frequently —but gutters will still clog.
🛠️ Why Routine Cleaning Matters
- Clogged gutters can cause foundation damage, basement leaks, and rotting fascia.
- Moss-covered roofs trap moisture, degrade shingles, and shorten your roof’s lifespan.
- Debris buildup invites pests like rodents and birds looking for nesting spots.
And remember—insurance doesn’t always cover damage caused by neglect.
