Vancouver, WA winters aren't about blizzards and snowdrifts — they're about relentless, grinding moisture. Months of continuous rain, periodic windstorms, and occasional freezing temperatures put enormous stress on your home's exterior. The damage is often slow and invisible until it becomes expensive.
The good news? A few hours of proactive preparation in the fall can prevent thousands of dollars in emergency repairs. Here's your complete checklist, organized by priority.
Priority 1: Clean and Inspect Your Gutters
This is the single most important thing you can do before winter. Full stop.
Clogged gutters during a heavy PNW rainstorm (and we get plenty) cause water to overflow and:
- Pool around your foundation, leading to cracks and basement flooding
- Back up under your roof edge, causing fascia rot and attic leaks
- Cascade down your siding, promoting mold and paint failure
- Erode your landscaping and garden beds
When to do it: Schedule your gutter cleaning for late November — after most deciduous trees have dropped their leaves but before the heaviest rains of December and January.
What to look for: While your gutters are being cleaned, have the technician check for loose hangers, sagging sections, leaking seams, and proper downspout drainage. Small repairs now prevent big failures during a storm.
Priority 2: Clean and Inspect Your Roof
Moss is your roof's worst enemy in the Pacific Northwest, and winter is when it does the most damage. Here's why:
- Moss holds moisture against your shingles like a sponge
- When temperatures drop below freezing, that moisture expands
- The freeze-thaw cycle loosens shingles and opens gaps
- Water penetrates through these gaps into your roof deck
- By spring, you have rot, leaks, and potentially mold in your attic
A professional roof cleaning in fall removes moss before the freeze-thaw cycle can cause damage. Our soft wash treatment kills moss at the root, so it won't grow back through the winter.
Also: Trim any overhanging branches that could break under ice or high winds and fall onto your roof. This is one of the most common causes of winter roof damage in our area.
Priority 3: Soft Wash Your Siding
Mold, mildew, and algae on your siding don't take a winter break — they thrive in the damp, cool conditions. Left unchecked through winter, they:
- Penetrate deeper into wood and fiber cement, causing accelerated deterioration
- Spread to areas that were previously clean
- Create dark, damp conditions that attract pests seeking winter shelter
A soft wash treatment in the fall kills all organic growth and applies a residual treatment that helps prevent regrowth through the winter months. Your home will look better, last longer, and start spring in much better condition.
Priority 4: Clean Your Windows
This might seem like a cosmetic concern, but there's a practical reason to clean your windows before winter: natural light.
Vancouver gets an average of just 8-9 hours of daylight in December, and many of those hours are overcast. Dirty windows block an additional 20-40% of the available light. Clean windows maximize every ray of weak winter sunshine, making your home feel brighter and more comfortable during the darkest months.
Winter is also when condensation on windows is heaviest. Clean glass and tracks reduce the surface area for mold to establish in the moisture.
Priority 5: Pressure Wash Walkways and Driveways
Algae and moss on concrete and stone surfaces become genuinely dangerous when wet or frozen. The Pacific Northwest's winter combination of rain and occasional freezing temperatures turns a mossy walkway into an ice rink.
Pressure washing your driveway, walkways, patio, and front steps removes the organic growth that makes these surfaces slippery. It's a safety issue, not just aesthetics.
