How to Weatherproof Your Home in Seattle’s Rainy Climate
Weatherproof Your Home in Seattle
As the days get shorter and the iconic Seattle drizzle sets in, it’s time for every homeowner’s essential fall ritual: weatherproofing your home in Seattle. With months of rain ahead, failing to prepare can mean roof leaks, foundation damage, invasive moss, mold growth, and rising heating bills.
This guide gives you a practical checklist to protect your home, lower your maintenance costs, and stay cozy throughout the rainy season.
1. Start at the Top – Your Roof & Gutters
Inspect Your Roof
Look for cracked, curled, or missing shingles. Even a small gap can let rainwater in. If you’re unsure, schedule a professional roof inspection.

Tackle the Moss
Moss is a Seattle specialty—but on roofs, it’s destructive. Moss acts like a sponge, holding moisture against shingles and speeding decay. Consider professional roof moss removal for safe, long-lasting results.
Clear Gutters and Downspouts
Clogged gutters are one of the biggest causes of siding and foundation damage. Remove leaves, pine needles, and debris so water flows freely away from your house.
Quick Tip:
Catching small issues early can prevent leaks that cost thousands to repair.
Secure the Building Envelope – Siding, Windows & Doors
Examine Siding & Paint
Look for cracks, gaps, or peeling paint. Applying a high-performance exterior waterproofing paint keeps moisture out and prevents wood rot. 🔗 This Old House: How to Paint Your House Exterior
Seal Gaps in Windows & Doors
On a breezy day, run your hand along window and door frames to feel for drafts. Apply fresh caulk around windows and add new weatherstripping to doors. This prevents water intrusion and lowers heating costs.
Why It Matters: A strong coat of paint is your first defense against Seattle’s constant moisture. 🔗 Energy.gov: Caulking & Weatherstripping
Why it matters:
Sealing drafts can save up to 20% on heating bills.
3. Defend the Foundation – Drainage, Basements & Crawl Spaces
Manage Surface Water
Ensure soil slopes away from your foundation and that French drains or yard drains are clear.
🔗 Seattle.gov Drainage Guidance
Why It Matters: Proper drainage prevents basement flooding and costly foundation repairs.
Inspect Your Basement or Crawl Space
Look for moisture, musty odors, or mold. Ensure vapor barriers are intact and vents are clear.
🔗 EPA: Moisture Control Guidance
Quick Tip: A dry crawl space reduces mold risk and improves indoor air quality.
Test Your Sump Pump
Pour water into the sump pit to check it turns on. If it fails, repair it before the rainy season peaks.

Why It Matters: A working sump pump is your last defense against basement flooding.
4. Prepare the Interior for a Cozy Winter
Promote Air Circulation to Prevent Mold
Use bathroom and kitchen fans to vent moisture outside. In basements or poorly ventilated rooms, consider a dehumidifier.
Service Your Furnace
Replace filters and schedule a professional tune-up. An efficient furnace keeps your home warm without driving up energy bills.
5. Know When to Call a Seattle Professional
Some tasks, like foundation repair, major roof work, or gutter installation in Seattle, require a licensed pro. If you spot damage beyond your DIY comfort zone, don’t wait. Calling trusted Seattle weatherproofing services now can save thousands in repairs later.
For authoritative local resources, you can also check Seattle Public Utilities’ drainage guidance to better understand how to manage stormwater around your property.
