Protecting Your Home from Unexpected Snow and Water in the Pacific Northwest

The Pacific Northwest is known for its mild winters and steady rainfall, but when sudden snowstorms, ice, or prolonged periods of heavy moisture occur, homes that are not properly prepared can suffer costly damage. Unlike regions that experience deep freezes every year, many homes in Washington and Oregon are not built for extreme winter events. This makes proactive protection especially important.

Whether you are a longtime homeowner or new to the region, understanding how to safeguard your home and how to respond if flooding occurs can help prevent major repairs, financial stress, and health risks.

Why Snow and Water Are a Unique Risk in the Pacific Northwest

In the Pacific Northwest, winter damage often occurs not from extreme cold, but from the combination of snow, freezing temperatures, and rain that follows shortly after. Snow accumulation can melt quickly, overwhelming drainage systems and exposing vulnerabilities in roofs, foundations, and basements. Freeze-thaw cycles can also cause ice dams, cracked pipes, and structural stress.

Flooding can also create secondary risks related to health, utilities, insurance coverage, and access to safe shelter, which homeowners should be aware of before a storm hits.

Key Areas to Protect Before the Next Storm

Roofs and Gutters

Snow buildup on roofs can add significant weight, especially on older homes or flat roofs that are common in the region. When snow melts and refreezes at roof edges, ice dams can form and force water back under shingles and into the home.

Clear gutters and downspouts so melting snow and rain can flow freely away from the house
Check for loose or missing shingles before winter storms arrive
Consider professional roof snow removal if accumulation becomes heavy or uneven

Drainage and Grading

Proper drainage is one of the most important defenses against water intrusion.

Ensure downspouts extend several feet away from the foundation
Confirm the ground slopes away from the home, not toward it
Keep exterior drains clear of debris, leaves, and ice buildup

Basements and Crawl Spaces

Basements and crawl spaces are particularly vulnerable during rapid snowmelt and heavy rain.

Seal foundation cracks and gaps where water could enter
Use a vapor barrier in crawl spaces to reduce moisture buildup
Test sump pumps before winter and add a battery backup if possible

Pipes and Plumbing

Freezing temperatures in a region unaccustomed to them can lead to burst pipes.

Insulate exposed pipes in crawl spaces, garages, and exterior walls
Disconnect garden hoses and shut off exterior water lines
Keep indoor temperatures consistent, even when away from home

If Flooding Occurs: Safety, Insurance, and Next Steps

Even with preparation, flooding can still happen. Knowing what to do next can protect your health and help you recover more quickly.

Insurance and Documentation

Flood insurance is separate from standard homeowners or renters insurance
Take photos and videos of damage immediately and document everything
Speak with your insurance provider before making permanent repairs or disposing of damaged items
Public flood insurance has coverage limitations, while private flood insurance may cover more
You may be eligible for an advance payment on your claim
Contact your auto insurance provider if vehicles are damaged by floodwaters

Health and Personal Safety

Floodwaters can carry germs, chemicals, and other contaminants.

Wash hands frequently with soap and disinfected water
Wear protective gear such as boots and gloves
Return home during daylight hours when possible to avoid unseen hazards
If entering at night, use flashlights and ensure power and gas are shut off
Call your gas company or 911 immediately if you smell gas or suspect a leak
Discard food, medications, and cosmetics that came into contact with floodwater
Have septic systems inspected and pumped after floodwaters recede

Power Outages and Carbon Monoxide Safety

Winter storms and flooding often lead to power outages.

Keep generators outdoors only and away from windows and doors
Ensure exhaust is not near openings to the home
Never burn charcoal indoors
Prepare a power outage kit with flashlights, batteries, lanterns, a portable radio, matches, a Mylar blanket, and a manual can opener

Homeowner Winter Preparedness Checklist

Clean gutters and downspouts
Inspect roof shingles and flashing
Extend downspouts away from the foundation
Test sump pump and backup power source
Seal foundation cracks and exterior gaps
Insulate exposed pipes
Disconnect outdoor hoses and shut off exterior water valves
Clear walkways, drains, and access points
Prepare a power outage and emergency kit
Monitor basements and crawl spaces during heavy rain or snowmelt
