Ice Dams & Roof Damage
Protect Your Roof From Dams & Damage
What Are Ice Dams?
An ice dam is a buildup of snow and ice usually along the edge of the roof above the eaves.
How Do Ice Dams Form?
Ice dams often collect along roofing edges in the winter when the cold, snow and ice hit. When melted water gets stuck in frozen snow and it re-freezes along the eaves where there is less heat on the roofing.
Who Cares? I LOVE Icicles!!
Melting, refreezing, more snow, more ice, more melting, more refreezing WILL cause damage to your roof.
The water that is trapped can get under the roofing shingles and water has an amazing ability to creep into the roof like a slow-moving glacier. It can work its way up to 10 feet into your attic or roof-space! As the “roof-glacier” approaches insulated warm air it will leak into the house causing possible damage to the ceilings, floors, walls, insulation, paint, and more.
For this to happen these variables must be present and if they are there is a higher likelihood that water may get into your home.
How Can I Prevent Ice Dams from Damaging My Home?
If damage is already caused, we are experts in repair and restoration.
However, the key is maintenance and prevention. At Proline, we know how to prevent ice dams from forming in the first place – keeping your interior safe from impending ice damage.
First, we ensure that your roof is cold. The main reason ice dams form is that the roof is unevenly warm. Patches of the roof, or just the topmost portion of the roof, gets above freezing while the bottom edge of your roof is below freezing. The melting snow from the upper portion of the roof thaws and then refreezes as ice towards the bottom edge of the roof, this new ice prevents more snow from melting and dripping off the roof the way it should. If an attic/roof is unevenly insulated or does not have roof or soffit vents, this becomes much more likely.
So, to prevent ice dams we make sure the roof is cold by:
- Installing roof/soffit vents to flush out that warm attic air
- Checking Insulation and replacing if necessary
- Plugging warm-air leaks from living space into the attic
Alternatively if all else fails, there are a few other options: snow-raking and heat cables to melt dams may be considered as a last resort.
