Winter Maintenance Tips for Mountain Homes

By Daniel Kovacs | Summit County Real Estate

Living in the Colorado mountains means embracing winter, and that includes proper home maintenance. At elevations between 9,000 and 11,000 feet, Summit County properties face conditions that Front Range homes never encounter: sustained temperatures below zero, snowfall totals exceeding 300 inches per season, and wind gusts that can reach 60 mph at exposed locations. A proactive approach to winter maintenance protects your investment and prevents costly emergency repairs.

Pre-Season Checklist

The best time to prepare for winter is September through mid-October, before the first major storms arrive. Schedule these tasks early because local contractors book up fast once cold weather hits.

• Furnace service: Have an HVAC technician inspect and tune your furnace. A standard service call runs $150 to $250 in Summit County. Replace the filter and confirm the system produces consistent heat across all zones.
• Roof inspection: Walk the perimeter and look for damaged shingles, loose flashing around chimneys, and gaps in ridge caps. A professional roof inspection costs $200 to $400 and can identify problems before snow makes them worse.
• Pipe insulation: Wrap exposed pipes in crawl spaces, garages, and exterior walls with foam insulation sleeves. Pay special attention to pipes on north-facing walls. The cost of insulation materials is under $100, while a burst pipe repair can exceed $5,000.
• Gutter cleaning: Clear leaves and debris from gutters so meltwater drains properly. Clogged gutters contribute directly to ice dam formation.
• Window and door seals: Check weatherstripping around windows and doors. Replace any cracked or compressed seals to reduce heat loss and prevent drafts.

Roof and Snow Management

Heavy snow loads are a real structural concern in Summit County. A cubic foot of packed snow weighs roughly 20 pounds, and after a big storm cycle, your roof can carry thousands of pounds.

• Install heat cables along eaves to prevent ice dams. Professional installation costs $800 to $2,000 depending on roof length.
• Clear snow when accumulation exceeds 2 feet on the roof. Use a roof rake from ground level to avoid climbing on icy surfaces.
• Check for proper attic ventilation to prevent ice dam formation. Warm air escaping into the attic melts snow unevenly, creating ice buildup at the eaves.
• Inspect the roof before winter for damaged shingles or flashing. Metal roofs perform better under heavy snow loads than asphalt shingles.

Ice Dam Prevention

Ice dams form when heat from the attic melts snow on the upper roof, and the meltwater refreezes at the colder eaves. This trapped water backs up under shingles and leaks into the home. Proper attic insulation (R-49 or higher recommended at this altitude), adequate soffit ventilation, and heat cables along the eave line are the three primary defenses. Homes in Breckenridge and Frisco at higher elevations see more ice dam issues than lower-elevation properties in Dillon or Silverthorne.

Plumbing Protection

Frozen pipes are the single most expensive winter emergency for mountain homeowners. A single burst pipe can cause $10,000 to $50,000 in water damage, depending on how quickly the problem is discovered.

• Insulate exposed pipes in crawl spaces and garages with heat tape and foam sleeves
• Know where your main water shutoff is located. Label it clearly so anyone staying in the home can find it.
• If leaving for extended periods, keep heat at 55°F minimum. Some property managers recommend 58°F for homes with plumbing in exterior walls.
• Consider pipe heating cables for vulnerable areas. Electric heat cables cost $1 to $3 per linear foot and use minimal electricity.
• Open cabinet doors under sinks on exterior walls during extreme cold snaps to let warm air circulate around pipes

Heating System Maintenance

Your heating system works harder in Summit County than almost anywhere else in the country. Winter temperatures regularly drop below -10°F, and your furnace may run continuously for days during cold snaps.

• Schedule furnace inspection before October. Annual service extends equipment life by 3 to 5 years.
• Replace filters monthly during heavy use (November through March)
• Stock firewood early if using a wood stove. A cord of seasoned pine runs $250 to $350 locally, and prices climb after November.
• Have chimneys cleaned annually. Creosote buildup is a fire hazard, and chimney fires are a real risk in mountain communities.

Propane Delivery Scheduling

Many mountain homes rely on propane for heating, cooking, or backup systems. Schedule automatic delivery before winter starts. During heavy storm cycles, propane trucks may not reach remote properties for several days. Keep your tank above 30% capacity at all times. Current propane prices in Summit County range from $2.50 to $3.50 per gallon depending on your provider and delivery frequency.

Thermostat Settings When Away

If you own a vacation rental or second home, proper thermostat management between visits is critical. Set the minimum temperature to 55°F across all zones. A smart thermostat with remote monitoring (Nest, Ecobee) costs $150 to $300 installed and lets you check temperatures from your phone. Some systems send alerts if the temperature drops below a set threshold, giving you time to contact a local caretaker before pipes freeze.

Snow Removal Options

Reliable snow removal keeps your property accessible and prevents liability issues on walkways and driveways.

• Professional plowing contracts: Monthly rates run $150 to $400 depending on driveway length and grade. Steep driveways cost more.
• Per-push pricing: $50 to $150 per visit, practical for properties with light traffic
• Heated driveways: Radiant heat systems embedded in concrete or asphalt eliminate plowing entirely. Installation costs $12 to $25 per square foot, but operating costs are modest at $200 to $500 per winter season.
• Snow blower: A quality two-stage snow blower ($800 to $2,000) handles most residential needs if you live on-site

Exterior Preparation

• Disconnect and drain garden hoses. Shut off exterior hose bibs from inside.
• Service snow removal equipment before the first storm
• Stock ice melt and sand for walkways. Avoid rock salt on concrete, as it causes surface damage at high altitude where freeze-thaw cycles are more intense.
• Trim branches that could damage structures under snow weight. Dead branches on pine and spruce trees are especially prone to breaking.

Caretaker Services for Second Homes

If your Summit County property sits vacant for weeks at a time, a local caretaker service provides peace of mind. Caretakers typically visit weekly or biweekly to check heating systems, inspect for leaks or frozen pipes, clear snow from entryways, and confirm the property is secure. Monthly caretaker fees range from $100 to $300 depending on the scope of service. Many local property management companies offer caretaker packages alongside full rental management.

Emergency Preparedness

Mountain winters can bring unexpected challenges. Power outages from heavy snow on power lines are common, and road closures on Highway 9 or I-70 can isolate communities for hours. (Source: U.S. Department of Housing).

• Keep flashlights, batteries, and candles accessible in a designated emergency kit
• Stock 3 days of non-perishable food and water (1 gallon per person per day)
• Have a backup heat source: a wood stove, propane fireplace, or portable kerosene heater
• Know plow schedules for your road and keep your county road department's number handy
• Maintain a battery-powered or hand-crank radio for weather updates during power outages
• Keep a shovel, ice scraper, blankets, and sand/cat litter in your vehicle from November through April
