Don’t Let Wisconsin Winter Catch You Off Guard: Essential Steps to Protect Your Home from Severe Storm Damage

Wisconsin winters are notoriously harsh, and homeowners across the state know that preparation is the key to avoiding costly storm damage. On average, Wisconsin experiences 3 to 5 winter storms per season and a significant ice storm once every 4 or 5 years. With the average date of the first snowstorm in Wisconsin being November 10, now is the perfect time to ensure your home is ready for whatever Mother Nature has in store.

Understanding Wisconsin’s Winter Weather Threats

Wisconsin’s climate presents unique challenges that can cause significant damage to unprepared homes. Wisconsin winters are beautiful—and brutal on roofs. Heavy, wet snow; polar-vortex cold snaps; freeze–thaw cycles; and spring windstorms all team up to test your shingles, flashing, gutters, and attic. The most common types of winter storm damage include:

• Ice Dams: Warm air leaking from the house melts the underside of rooftop snow. Meltwater runs to the cold eaves, refreezes, and forms a dam that backs water up under shingles. Result: stained ceilings, soggy insulation, and rotten sheathing.
• Snow Load Damage: Wet, heavy snow can stress framing and decking. Prolonged loads cause sagging ridges, popped fasteners, and cracked plaster/drywall.
• Wind-Driven Damage: Gusts push water into weak points—ridge vents, valleys, chimneys, skylights, and sidewall transitions—especially where flashing was improperly installed.

Essential Pre-Winter Home Preparations

Taking proactive steps before winter arrives can save you thousands of dollars in potential damage. Here’s your comprehensive preparation checklist:

Roof and Exterior Maintenance

To stay safe and warm this winter, ensure your home is maintained and ready to weather the cold and snowy season. Insulate any water lines that run along exterior walls so your water supply will be less likely to freeze. Seal cracks, caulk and weather-strip drafty doors and windows. Install storm windows and insulated doors. Install heating tape on your roof if you have problems with ice dams. Cover windows with plastic from the inside. Repair roof leaks. Cut away tree branches that could fall on your home or other structures during a storm.

Additional roof preparations include:

• Clean out gutters and downspouts so melting snow can drain properly. Check your roof for loose shingles or signs of wear. Install heat cables or guards in areas prone to ice damming.
• Make sure snow removal equipment is in good working condition. Have salt on hand to melt ice on walkways and sand or kitty litter to generate temporary traction.

Heating System and Interior Preparations

Your home’s heating system is critical during Wisconsin winters. Have sufficient heating fuel in case regular fuel sources are cut off. For example, store a good supply of dry, seasoned wood for your fireplace or wood-burning stove. Make sure your furnace gets a tune-up, so it is running efficiently. Don’t forget to check the furnace filter.

Protect your plumbing by following these guidelines:

• Keep your thermostat set to 60°F or higher, even when you’re not home. Insulate pipes in basements, crawl spaces, and attics. Open cabinet doors in kitchens and bathrooms to let warm air circulate around plumbing.
• Schedule a furnace or boiler inspection to make sure your heating system runs safely and efficiently.

Emergency Preparedness Planning

Create a communication and disaster plan for your family before a winter storm hits. Assembling an emergency supply kit for your home and vehicle in winter can save your life if a severe winter storm or extreme cold event leaves you without power or stranded in a vehicle.

Your emergency kit should include:

• Flashlights and extra batteries
• Battery-powered or hand-crank radio
• First aid supplies
• Non-perishable food for at least 72 hours
• Water (one gallon per person per day)
• Medications and personal hygiene items
• Warm clothing and blankets

Post-Storm Inspection and Safety

After a winter storm passes, it’s crucial to inspect your property for damage. Missing, creased, or lifted shingles—often along ridges and edges. Sagging ridgelines, bowed eaves, or cracked drywall inside (possible snow-load stress). Ice buildup at the eaves or icicles attached to gutters/soffits. Damaged gutters, downspouts, or soffit panels. Around chimneys/skylights: misaligned flashing, exposed fasteners, or settled snowpack that forms a “moat.”

Remember these important safety tips:

• Don’t climb a snowy roof. It’s not worth the fall hazard—call a contractor equipped for winter conditions.
• Check your roof and clear accumulated snow to avoid roof collapses.
• Use a roof rake from the ground to pull down the first 3–4 feet of snow after big storms—especially on low-slope or north-facing sections. Never chip ice with metal tools (you’ll damage shingles).
