Stop ice dams before they start

By Viotell Metal Concepts. 

Smart roofing isn’t just about looks; it’s your best defense against winter’s worst. 

Every winter, perfectly good homes fall victim to a sneaky rooftop menace, and most homeowners don’t even know it's happening until it’s too late. Ice dams don’t knock; they creep in under shingles, soak insulation and silently destroy drywall. But here’s the truth: this isn’t just a cold-climate curse you have to live with. With smart planning and the right roofing strategy from Viotell Metal Concepts, ice dams are a problem you can eliminate before they cost you thousands. Here's how to stay one step ahead of the freeze. 

What are ice dams?  

Ice dams are ridges of solid ice that form along the edge of your roof during winter. They develop when snow on your roof melts (often from attic heat) and runs down toward the colder eaves, only to freeze again.  

Over time, this frozen barrier traps additional meltwater behind it. With nowhere else to go, the water can seep under shingles and leak into your attic, insulation, or interior walls.  

The damage can be serious, leading to mold, rot, ruined ceilings and even structural issues.  

 What causes ice dams?  

Ice dams form when a few key conditions come together:  

• Warm attic: Heat escaping from your home melts snow unevenly. Poor insulation or lack of air sealing is often to blame.  
• Cold roof eaves: The lower edge of your roof stays cold, refreezing meltwater as it hits the edge.  
• Snow accumulation: Heavy snowfall plus fluctuating temperatures sets the stage for repeated melting and freezing.  

7 effective ways to prevent ice dams  

Here’s how you can reduce your risk and prevent ice dam damage:  

1 – Improve Attic Insulation  

Better insulation keeps heat where it belongs in your living space, not in your attic. Focus on sealing and insulating around attic hatches, pipes and lighting fixtures.  

2 – Enhance roof ventilation  

Soffit vents, ridge vents or gable vents help circulate cold outside air through your attic. This keeps the roof deck closer to outside temperatures and prevents uneven melting.  

3 – Install ice & water shield  

This waterproof membrane goes beneath your roof covering along eaves and valleys. It provides an added layer of protection in case water backs up under the shingles.  

4 – Remove snow from the roof  

Use a roof rake to gently clear snow buildup near the edges of your roof after a storm. This limits the volume of melting water and helps prevent ice dams from forming.  

5 – Seal attic air leaks  

Look for gaps around ducts, recessed lighting and plumbing vents then seal them up with caulk or spray foam to prevent warm air from reaching your roof deck.  

6 – Install heated cables  

In areas with persistent ice dam issues, heated cables along eaves and valleys can keep   

7 – Design for proper roof pitch  

Steeper roofs shed snow more efficiently. If you’re building new or replacing your roof, consider a higher pitch and snow-friendly material like metal.  

Why ice dam prevention matters  

High-elevation areas experience extreme freeze-thaw cycles, prolonged snowpack and harsh UV exposure. These factors increase ice dam risks and demand better roof systems.  

Local codes often require upgraded insulation, ice barrier membranes and durable materials that stand up to the mountain climate. At Viotell Metal Concepts, we specialize in these systems and know exactly what your roof needs to perform.
