How To Prevent Snow And Ice From Damaging Your Roof

Posted on: 6 April 2018

Your roof faces different threats during the cold season, and one of these threats is due to the accumulation of snow and ice on the roof. Here are a few measures to help prevent snow and ice from damaging the roof:

Remove Snowfalls As Soon As Possible

There is a limit to how much weight your roof can handle. Allowing your roof to bear unlimited snow can cause a roof collapse because the weight of the snow may exceed the maximum load the roof can hold. Therefore, don't allow too much snow to accumulate on the roof; remove the snow as soon as possible. You can remove the snow on your own if you have a long rake that you can use from the ground. Otherwise, get a professional to clear away the snow.

Prevent Ice Dam Formation

It is not just the weight of snow that can affect your roof; you also have to worry about the formation of ice dams. Ice dams form when snow high up on the roof melts, flows down the roof, and refreezes on colder areas at the edges of the roof. The ice then forms a dam behind which more water from melting snow can collect and cause damage to the roof. Here are some tips for preventing ice dam formation:

  • Stop attic air losses that heat up the roof
  • Insulate the attic
  • Minimize heat sources in the attic
  • Keep gutters clean
  • Install a heating tape along the edges of the roof

Ensure Roof Drainage Is Efficient

The snow and ice on the roof can also cause damage when they melt and the water stays on the roof. The more water stays on the roof, the more it will get the chance to seep through the water barrier and cause internal roof damage. Water staying on the roof for a long time can also corrode the metal parts and decay to the wood. Therefore, if your roof is not draining as efficiently as it should, consult a roofing contractor to diagnose and fix the problem as soon as possible.

Prevent Snow Avalanche

A big chunk of snow falling off the roof can cause damage to the roof surface shingles or roof installations. Ideally, snow should fall off the roof in small chunks that can't cause serious damage. The best way to ensure this is to install snow guards, which allow ice and snow to melt or break into little chunks before flowing or sliding down the roof.
