Common Winter Maintenance Issues in High-Elevation Denver Homes

Denver’s high-altitude climate brings stunning views and crisp winter days, but it also introduces unique property maintenance challenges for landlords and homeowners. Between sub-freezing temperatures, snow accumulation, and freeze-thaw cycles, winter can take a toll on residential rental properties.

Whether you’re new to managing rentals in Denver or simply looking to prevent costly surprises, understanding the most common winter maintenance issues is the first step toward keeping your property in good shape all season long.

In this guide, we’ll walk through the most frequent problems, why they happen in Denver's climate, and how proactive upkeep can help you avoid expensive repairs or tenant complaints.

‍

1. Frozen Pipes and Plumbing System Failures

Frozen pipes are among the most dreaded winter issues in high-altitude areas like Denver. When temperatures drop below freezing, any exposed or poorly insulated pipes are at risk of freezing and bursting—leading to leaks, water damage, and expensive repairs.

Why It Happens

• Denver's fluctuating temperatures often dip below freezing at night and warm up during the day, creating expansion and contraction in plumbing systems.
  
  
• Homes with crawl spaces, unfinished basements, or exterior hose bibs are especially vulnerable.
  
  

Prevention Tips

• Insulate pipes in unheated areas like garages and basements.
  
  
• Disconnect garden hoses and install frost-proof hose bibs.
  
  
• Encourage tenants to keep indoor temperatures above 55°F, even when away.
  
  
• Consider smart leak detectors or temperature sensors to catch issues early.

2. Ice Dams and Roof Leaks

Ice dams form when snow melts on a warm section of a roof and refreezes at the colder eaves, creating a barrier that traps more melting snow. Eventually, water backs up under the shingles and leaks into the home.

Why It Happens in Denver

• The city experiences both sunny days and freezing nights, a perfect recipe for the melt-refreeze cycle.
  
  
• Homes with poor attic insulation or ventilation see more ice damming.
  
  

Solutions

• Ensure your attic is well-insulated to keep warm air from escaping.
  
  
• Add proper ventilation to keep roof temperatures consistent.
  
  
• Use a roof rake to remove snow from the edges before it refreezes.
  
  
• Inspect and repair roof flashing before winter sets in.

3. HVAC System Stress and Failure

Denver winters can push HVAC systems to their limits. Older units may struggle to maintain temperature or fail altogether during extreme cold.

Common HVAC Winter Issues

• Clogged filters reduce airflow and efficiency.
  
  
• Ignition or pilot light failures on older furnaces.
  
  
• Uneven heating due to duct leaks or blocked vents.
  
  

What to Do

• Schedule an HVAC inspection and tune-up each fall.
  
  
• Replace air filters every 1–3 months.
  
  
• Seal ductwork and ensure vents are clear of furniture or debris.
  
  
• Remind tenants not to use space heaters as a primary heat source.

4. Snow and Ice Buildup on Walkways

Slip-and-fall injuries are a major liability for landlords. Icy driveways, sidewalks, and entryways can pose serious safety risks for tenants and guests.

Property Owner Responsibilities

In Denver, property owners are required to remove snow and ice from public walkways adjacent to their properties within 24 hours after snowfall ends.

Best Practices

• Provide tenants with shovels, salt, or sand, especially in single-family homes.
  
  
• Consider hiring a snow removal service for multi-family properties.
  
  
• Use de-icing products that are safe for concrete and landscaping.
  
  

‍

5. Cracked Driveways and Foundations

Concrete expands and contracts with temperature changes. In Denver’s climate, repeated freeze-thaw cycles can create or worsen cracks in sidewalks, driveways, and foundations.

Signs of Trouble

• Hairline cracks that widen over time.
  
  
• Water pooling near the foundation after snow melts.
  
  
• Gaps between the driveway and structure.
  
  

Prevention Measures

• Seal cracks in concrete before winter to prevent water intrusion.
  
  
• Ensure proper drainage away from the property.
  
  
• Regrade landscaping if water pools near the foundation.
  
  

‍

6. Clogged or Damaged Gutters

Clogged gutters prevent melting snow from draining properly. This can lead to overflow, ice buildup, and water damage to siding, windows, and foundations.

What to Watch For

• Gutters filled with leaves or debris.
  
  
• Ice hanging from gutters or forming icicles.
  
  
• Water stains or peeling paint around the roofline.
  
  

Gutter Maintenance Tips

• Clean gutters in late fall before snow begins.
  
  
• Install gutter guards to reduce debris buildup.
  
  
• Make sure downspouts direct water at least 3 feet from the foundation.

7. Window and Door Drafts

Cold drafts can make a home uncomfortable and cause heating bills to spike. Tenants often complain about chilly rooms even when the heat is running.

Fixes and Upgrades

• Use weather stripping and door sweeps to seal gaps.
  
  
• Apply insulating window film or thermal curtains.
  
  
• Upgrade to energy-efficient windows where feasible.
  
  

Encouraging tenants to report drafts early can prevent bigger heating problems later in the season.

8. Roof Damage from Heavy Snow Loads

Although Denver gets fewer heavy snowstorms than mountain towns, occasional blizzards can dump significant snow. Accumulated snow adds weight and may strain the roof, especially if it’s older or already compromised.

Tips to Avoid Roof Stress

• Clear large snow accumulations with a roof rake.
  
  
• Inspect for sagging or creaking after storms.
  
  
• Schedule a professional inspection if your roof is 15+ years old.
  
  

‍

9. Rodent and Pest Intrusion

As temperatures drop, pests like mice, squirrels, and raccoons look for warm places to shelter. Gaps in siding, vents, or crawlspaces become easy access points.

What Landlords Should Do

• Seal exterior gaps and holes with caulk or hardware cloth.
  
  
• Install vent covers and chimney caps.
  
  
• Schedule seasonal pest inspections.
  
  
• Educate tenants about signs of infestation (droppings, scratching sounds, etc.).
  
  

‍

10. Tenant Communication Gaps

Even the most well-maintained properties can suffer if tenants don’t know how to respond to cold weather issues. Lack of communication is often the root cause of escalated problems.

Proactive Communication Tips

• Send seasonal maintenance reminders to tenants in early fall.
  
  
• Provide instructions for emergency shutoffs (water, gas, heat).
  
  
• Share tips on preventing frozen pipes or spotting early signs of damage.
  
  

Having a clear line of communication fosters tenant cooperation and minimizes winter risks.
