An ice dam is a ridge of ice that forms at the edge of a roof and prevents melting snow (water) from draining off the roof. The water that backs up behind the dam can leak into a home and cause damage to walls, ceilings, insulation and other areas.
Here’s what you need to know.
What Are Ice Dams?
A pile of ice on your roof isn’t harmful – until things start warming up. When water melting off your roof starts to pool behind the ice, it gets forced up under your shingles. With time, it’ll soak in and start dripping through the roof into the soffits, which are the outside overhangs of your roof, and into your walls. In the worst cases, it can drip through the ceilings in your home. Moisture entering the home from ice dams can also lead to the growth of mold and mildew, which can cause respiratory problems.
Water damage is expensive to repair, but for the most part – at least when it comes to roofing – it’s usually preventable.
So how can you prevent ice dams on your roof?
Ideally, you’ll have a roof inspection before winter hits. Many roofing companies offer completely free inspections. That way, if there’s a problem with your roof, you can have it repaired and head off bigger issues.
If you don’t have time or can’t get a roof inspection, you can:
- Seal up your attic so that heated air from your home can’t get in there and warm up the roof.
- Make sure you have enough insulation in your attic.
- Add soffit vents and roof vents if you don’t already have them. You want fresh air coming through your attic to keep it the same temperature as the outdoors, which can help prevent the roof from heating up and melting ice.
