Thaw after Deep Freeze Can Wreak Havoc on Your Home

A February thaw is here and while it will undoubtedly be a relief from the recent temperatures, the rapid warm-up also comes with some hazards, especially for homeowners.

The build-up of ice along roofs and gutters can lead to sudden problems when the ice melts. When it refreezes, it causes ice damming and that ice damming can cause things like water stains inside the home. Water dripping through the soffits can push gutters off the home and can also push shingles off.

What can you do to prevent an ice dam from building up?

Proper insulation

Attic in need of insulationKeep your attic space at the same temperature as the outside air. As heat rises from your home into the attic, it will cause the snow and ice on your roof to melt quickly, which when it refreezes causes the ice dam. Using proper insulation will keep the heat in your home, but more importantly it will keep it from escaping into your roof shingles through your attic. If there are air leaks, warm air will pass through traditional insulation. The leaks need to be sealed for the insulation to do its job. To do a proper job in sealing air leaks, all insulation should first be removed.

Insulation also prevents moisture from forming inside your attic, which can create mold and mildew.

Roof raking

Some experts say whenever there is a big snowstorm, homeowners should use a roof rake to scrape the first two or three feet of their roofs free from snow. They recommend doing this within 24 hours of the snowfall. This frees up the bottom area of the roof so that as the water does run down, it doesn’t get stuck in the snow and gets right off the gutter and also right off the roof.

Be careful not to chop at your roof with the rake as this can damage shingles.

Heater cables

If you can’t reach the first few feet of your roof to rake it, you may choose to install heater cables. The cables line the first few feet along the eaves of your home and even run through the gutter, to help ice and snow melt and keep the moisture free-flowing.

Ice can pose a danger to gutters as it is heavier than water and snow, causing gutters to droop under the weight. Expanding ice can also push apart gutter seams and push gutters away from the fascia which attaches them to the home.

Do you have an ice dam? What should homeowners look for?

  • If you see Ceiling Water Damagewater spots inside your home this could just be tip of the iceberg – you may have inches of damp insulation in your attic.
  • If you see water pouring off of the soffits of your home, it is likely running out through the attic and could be rotting out the wood.
  • If you see water running between the gutters and the fascia board, there may also be problems.
  • Have the chimney inspected. Cracks and pieces of brick lying on the roof indicate that ice and water have gotten in between the mortar and expanded.

How to Remove Ice Dams – Hire a Pro

There are plenty of hack methods for removing ice dams such as using an axe, ice pick, salt tablets, heat cables and a pressure washer. If ice dams need to be removed, hire a pro to steam them off. Don’t let anyone near your roof with a pressure washer or the shingles might end up discolored.
