Ice dams are a common winter issue that can lead to serious damage, including roof leaks and structural deterioration. At SkyRight, located in Coeur d’Alene, ID, we ensure our clients understand how to protect their homes from ice dams. Below are actionable steps to prevent ice dams and maintain a safe, durable roof.
What Causes Ice Dams?
Ice dams form when snow on the roof melts, runs down, and refreezes at the roof’s edge. This happens when the roof’s higher sections are above freezing due to attic warmth, while the edges remain cold. The resulting ice blocks melted snow, forcing water under shingles and causing leaks.
Fact Highlight: Over 35% of winter roof damage in the U.S. is caused by ice dams, costing homeowners millions annually.
Steps to Prevent Ice Dams
1. Insulate Your Attic
Proper insulation minimizes heat transfer from your home into the attic, keeping the roof cold and reducing snowmelt. Aim for an R-value of R-40 or higher by adding 12–14 inches of fiberglass or cellulose insulation. Blown-in insulation is particularly effective for covering gaps.
2. Seal Attic Air Leaks
Warm air leaking into the attic through gaps in drywall, light fixtures, or plumbing pipes can raise roof temperatures. Use caulk or foam to seal these leaks and improve energy efficiency.
Pro Tip: Sealing attic air leaks can reduce heating costs by up to 20% annually.
3. Improve Roof Ventilation
Install soffit vents to draw in cold air and ridge vents to expel warm air, maintaining consistent roof temperatures. Ensure you have one square foot of vent space for every 300 square feet of attic floor area.
Secondary Ice Dam Prevention Methods
Use an Ice and Water Barrier
During your next roof replacement, install an adhesive ice-and-water barrier under shingles near the roof edge. This provides an additional waterproof layer to prevent leaks.
Rake Snow After Heavy Storms
Using a snow rake to remove excess snow prevents melting and refreezing. Focus on clearing areas prone to ice dams, such as roof valleys.
Install Heat Cables
Heat cables can be placed along roof edges and in gutters to melt snow and ice. They are ideal for hard-to-insulate areas or roof sections with persistent ice dam issues.
What to Do if Ice Dams Have Already Formed
- Rake the Snow: Carefully remove snow from the affected area using a snow rake. Avoid climbing on the roof, as icy surfaces are dangerous.
- Hire Professionals: Steam removal by a professional roofing company is the safest and most effective way to eliminate ice dams without damaging shingles.

FAQs
1. What are the signs of ice dam damage?
Watch for peeling paint, water stains on ceilings, or sagging drywall near roof edges.
2. Can all roofs be vented for ice dam prevention?
Flat roofs and angled ceilings may require alternative methods, such as heat cables or additional insulation.
3. Are heat cables safe for all roofs?
Yes, but they must be installed properly to avoid electrical issues and ensure effective melting.
4. How much does insulation help with ice dam prevention?
Upgraded insulation reduces heat loss, keeping your roof cold and minimizing the risk of ice dams.
5. Should I attempt to remove an ice dam myself?
DIY removal risks injury and roof damage. Professional steaming is the safest option for stubborn ice dams.
