Learn how to prevent ice dams and protect your home from winter water damage. Get expert tips for prevention and call Disaster Response if damage occurs.
As colder months approach in Idaho and across the Northwest, homeowners face a hidden winter danger: ice dams. These ridges of ice that form on the edge of your roof can cause serious water damage, leading to costly repairs if not prevented.
Below we’ll answer some of the most common questions homeowners search for online about ice dams, prevention, and what to do if damage occurs.
What is an ice dam?
An ice dam forms when heat escapes from your home, warming the roof and melting snow. As the water runs down to the colder roof edges, it refreezes into ice. Over time, this creates a barrier (a “dam”) that traps additional water behind it.
That water then seeps under shingles, into insulation, drywall, and ceilings, causing leaks, mold growth, and structural issues.
What causes ice dams on a roof?
Ice dams typically form because of:
-
Poor insulation in the attic (heat loss through the roof)
-
Inadequate ventilation in the attic or roofline
-
Heavy snowfall followed by fluctuating temperatures
-
Blocked or clogged gutters that prevent water from draining
How do I prevent ice dams?
Here are some of the most effective ways to protect your home:
-
Improve attic insulation: Keep warm air inside your home, not your roof.
-
Ensure proper ventilation: Attic vents help regulate roof temperature.
-
Clear snow safely: Use a roof rake to remove snow before it builds up.
-
Keep gutters clean: Remove leaves, debris, and ice buildup.
-
Seal air leaks: Check around chimneys, vents, and light fixtures for heat loss.
What should I do if I already have an ice dam?
-
Do NOT chip away at it: This can damage shingles and roofing materials.
-
Use calcium chloride: Avoid rock salt (it damages shingles and plants).
-
Call a professional: Roof and water mitigation experts can remove dams safely and prevent further damage.
What happens if an ice dam causes water damage in my home?
Water damage from ice dams can spread quickly, causing:
-
Wet insulation and drywall
-
Mold and mildew growth
-
Stained ceilings and walls
-
Structural damage
This is where Disaster Response comes in.
