Ice damming is something we normally worry about in spring but it is mid January and SGI is sharing tips with homeowners on how to avoid potential damage from the sudden thaw.

The provincial government insurer says the freeze-thaw cycle creates ideal conditions for condensation and ice damming. Both will cause a lot of damage to the walls, ceiling and insulation of your home. They may even lead to mould.

SGI officials say the snow becomes a layer of insulation on the roof, warms up the air in the attic and with poor attic ventilation that can lead to condensation.

The freeze-thaw cycle also causes snow to melt and roll down to the edge of the roof and soffits. Unless it can melt and drain properly it will freeze and build up over time causing ice dams.

It is recommended to get the snow off your roof using a roof rake or hire a professional. Clean the snow and ice out of the vent on your roof, clear your gutters and downspouts, make sure there is good airflow in the roof and that fans and ventings are sealed. keeping your house warmer and preventing your furnace from working harder to heat it.

Icicles on the roof can be the first sign of an ice dam, dark coloured icicles are a very good bet there is an ice dam because it is caused by water coming into your attic, picking up dirt and taking it back outside.
