Preventing Ice Dams on Your Roof: A Winter Guide

Ice Dams Are Typically Caused by a Winter Heat Loss Problem

Winter can be a beautiful season, but it also brings challenges for homeowners, particularly when it comes to ice dams on roofs. Ice dams can cause significant damage to your home if not properly managed. In this guide, we will explore what ice dams are, why they form, and how you can prevent them in order to protect your home.

How to Prevent Ice Dams

Preventing ice dams involves addressing heat loss via air leakage through the ceiling and proper water drainage. Here are some effective strategies:

• Seal Air Leaks – They are a prime source of heat loss that should be investigated first. Seal any gaps, cracks, or openings around chimneys, pipes, and attic hatches that may allow warm air to escape into the attic. Using caulk or weatherstripping can help minimize heat loss.
  
  
• Ensure Adequate Ventilation - Good ventilation allows cold air to circulate in the attic, preventing warm spots that contribute to ice dam formation. Ridge vents, soffit vents, and gable vents can help regulate temperature effectively.
  
  
• Improve Attic Insulation - Proper insulation in your attic helps maintain a consistent roof temperature, preventing uneven snowmelt. Focus on insulating the attic floor to keep heat from escaping into the roof space.
  
  
• Keep Gutters Clean - Clogged gutters can trap snow and ice, exacerbating ice dam formation. Regularly clean your gutters and downspouts to ensure proper drainage and water flow.
  
  
• Use a Roof Rake - After heavy snowfall, use a roof rake to remove excess snow from your roof. This reduces the chance of snow melting and refreezing at the eaves.
  

What to Do If You Have an Ice Dam...

If you already have an ice dam forming, take these steps:

• Safely remove snow using a roof rake to minimize additional buildup.
• Melt ice with calcium chloride. Avoid rock salt, which can damage shingles and vegetation.
• Contact the professional at BUSTAMANTE ENGINEERS if damage occurs to take the proper steps and prevent future occurrences.
