Ice Dams: The Silent Roof Destroyer

If you've noticed icicles hanging from your gutters or eaves, you might have more than just a pretty winter scene. Ice dams form when heat escapes through your roof, melting snow that then refreezes at the colder eaves. This creates a dam that forces water back under your shingles.

Signs you have an ice dam:

• Large icicles hanging from gutters or roof edges
• Water stains on ceilings or walls near exterior walls
• Sagging gutters
• Ice buildup in valleys of your roof

What you can do:

• Safely remove snow from your roof using a roof rake — work from the ground
• Improve attic insulation and ventilation to reduce heat loss
• Keep gutters clear throughout winter
• Never chip away ice with tools — this can damage shingles

Frozen Pipes: Prevention Is Everything

When temperatures plunge to -20°F or colder, frozen pipes become a real threat. A burst pipe can cause catastrophic damage, flooding your home and leading to mold issues if not addressed immediately.

Vulnerable areas to monitor:

• Exterior walls, especially on the north side of your home
• Crawl spaces and basements
• Garage areas
• Under sinks on outside walls
• Anywhere pipes run through unheated spaces

Prevention steps:

• Let faucets drip slightly during extreme cold snaps — even a trickle helps
• Open cabinet doors under sinks to allow warm air circulation
• Keep your thermostat consistent, even when you're away
• Disconnect and drain outdoor hoses
• Insulate exposed pipes in crawl spaces, attics, and garages
• Seal air leaks near pipes

Furnace and Heating System Care

Your furnace is working harder than ever right now. A breakdown during a January cold snap isn't just inconvenient — it's dangerous.

Monthly checks you should do:

• Replace or clean furnace filters — monthly during heavy use
• Listen for unusual noises: grinding, squealing, banging
• Check that all vents are clear and open throughout your home
• Ensure carbon monoxide detectors are working properly
• Monitor your energy bills for unusual spikes

If your system is short-cycling, struggling to maintain temperature, or making strange sounds, don't wait. A small issue now can become a complete system failure when you need it most.

Snow Load on Your Roof

Northern Wisconsin homes are built for snow, but even our sturdy roofs have limits. Most residential roofs can handle 20–25 pounds per square foot, but wet, heavy snow adds up fast.

Watch for these warning signs:

• Sagging ceiling or roof deck
• Doors that suddenly stick or won't close properly
• Cracking sounds from the roof or ceiling
• Cracks in interior walls or masonry
• Severe ice damming

Basement and Crawl Space Moisture

Just because it's winter doesn't mean moisture issues go away. Temperature fluctuations and snow melt can create significant problems. Check for frost on foundation walls or floor joists, musty odors, standing water or dampness, and ensure your sump pump is functioning by pouring water into the pit to test it.

Exterior Maintenance You Can't Ignore

• Clear snow away from your foundation — at least 2–3 feet
• Watch for ice buildup around doors and windows
• Check that dryer and bathroom vents aren't blocked by snow or ice
• Ensure natural gas meters and vents remain accessible and clear
• Monitor deck and porch structures for stress from snow weight

Document Everything

If you experience damage this winter, documentation is crucial for insurance claims. Take photos of problem areas, keep receipts for emergency repairs, note dates when issues first appeared, and track weather conditions during extreme cold or heavy snow events.

For Home Buyers: Winter Showings Reveal the Truth

If you're house hunting this winter, you're actually in a great position. Winter showings reveal issues that might be hidden in summer. Does the house feel drafty? How well does the heating system keep up? Are there ice dams or frost patterns? These are valuable clues about a home's condition and efficiency.
