Winter brings captivating snowfalls that transform streets into a winter wonderland. However, this beautiful snow can lead to the formation of ice dams, which can harm your roof. Recognizing what causes this issue and understanding how to prevent it is crucial to maintaining your home’s integrity and safety.
What Are Ice Dams?
Insufficient attic insulation and ventilation are common culprits behind ice dam formation. Warm air that escapes into the attic can increase your roof’s temperature, causing the snow on top to melt. As the water flows down the roof to the colder eaves, it refreezes and forms an ice dam. This ice formation can prevent melted snow from properly draining, increasing the likelihood of water intrusion and leaks. The existence of large icicles dangling from your gutters is a common indicator that ice dams may be forming.
What Can They Do to Your Home?
Water Damage
Water backed up beneath ice dams can seep under shingles and eventually infiltrate indoor spaces. Over time, it can damage walls, ceilings and insulation. Excessive moisture can compromise your home’s structural integrity and encourage mold growth when left unaddressed.
Roof Damage
The weight of ice dams can strain gutters and roofing components. Additionally, freeze-thaw cycles can lift shingles, creating entry points for water.
Safety Hazards
Icicles and ice sheets can endanger your household. These ice formations can fall and potentially injure individuals or pets.
How Do You Prevent Ice Dams?
Ensuring proper attic insulation and ventilation can prevent heat from escaping through the roof, reducing the chances of ice dam formation. Sealing gaps and cracks on your roof can further lower the risk of this issue.
Keep gutters and downspouts clear of debris to allow melted snow to flow away from your roof and home. Regular snow removal can prevent ice dam formation. However, this task is best left to professionals as it can be dangerous.
If you notice ice dams on your roof, you must act swiftly but safely.
