Pacific Northwest Home Maintenance Checklist

Why Oregon Homes Need More Maintenance Than Most

The Pacific Northwest's wet winters, mild summers, and heavy tree canopy create a unique set of challenges for homeowners. Moss grows aggressively. Gutters fill constantly during rainy season. Moisture penetrates everywhere. Homes that thrive in Arizona or Texas need a fundamentally different maintenance approach here.

This checklist covers every critical maintenance task, organized by season, so nothing falls through the cracks.

🌧️ Fall (September – November)

This is your most critical maintenance season. The rainy season is coming, and everything needs to be prepared.

• Clean gutters after leaf drop (late October – early November). This is non-negotiable.
• Inspect roof for moss, damaged shingles, and loose flashing before heavy rains begin.
• Apply moss treatment if moss was present during summer.
• Clean or seal driveways and decks before the wet season locks in stains.
• Book Christmas light installation if desired — crews fill up fast.
• Trim overhanging branches that could drop on the roof or clog gutters.
• Check downspouts flow freely to ground-level drains.
• Inspect exterior paint and caulking for cracks or peeling before moisture season.

❄️ Winter (December – February)

• Monitor gutters after major storms. One big storm can fill them with debris.
• Check for ice dams along the roofline — these form when heat escapes through the roof and melts snow unevenly.
• Keep walkways clear of moss and algae growth, which becomes slippery when wet.
• Inspect basement/crawlspace for moisture intrusion after heavy rain.
• Ensure downspout extensions direct water away from the foundation.

🌸 Spring (March – May)

• Clean gutters again — spring is your second annual cleaning.
• Pressure wash driveways and walkways to remove winter buildup.
• House wash — spring is the ideal time to clean siding after a wet winter.
• Inspect deck and fence for moisture damage, rot, or loose fasteners.
• Re-treat moss on roofs and ground-level surfaces.
• Clean windows inside and out after the grey season.
• Aerate and reseed lawn to recover from winter.

☀️ Summer (June – August)

• This is your window for major projects — remodeling, deck installation, exterior painting.
• Seal or stain decks after cleaning. Summer's dry weather is ideal for penetrating sealers.
• Trim trees to reduce shade on the roof (slows moss growth).
• Inspect and maintain irrigation systems.
• Clean gutters mid-summer if you have heavy tree coverage — seeds and debris accumulate even without rain.
• Plan fall maintenance and book contractors early.

Annual Costs to Budget

A reasonable annual home maintenance budget for an Oregon homeowner is 1–2% of your home's value. For a $350,000 home, that's $3,500–$7,000 per year across all maintenance tasks. Preventive maintenance consistently costs far less than reactive repairs.
