Depending on the season, your roof faces various challenges, from unforgiving elements to harsh weather conditions. This winter, there’s one roofing problem that homeowners should watch out for – ice dam formation.
How Are Ice Dams Formed?
Ice dams are formed when melted snow from the roof refreezes on the overhang of your roof or gutters. As this process goes on, the accumulated ice ultimately becomes a blockage, rendering the melted snow unable to flow off the roof. The standing water then ends up soaking the roof sheathing and insulation, resulting in leaks. Due to their weight, ice dam formations can damage your roof, especially your gutters. Ice dams can also become a safety hazard when they become too heavy as they might fall on the people and property below.
How Can Ice Dams Be Prevented From Forming?
The best way to prevent ice dams from forming is by ensuring that the cycle does not begin in the first place. This means that homeowners should keep the temperature of their attics and roofs from becoming too warm so that the snow doesn’t melt. Roofing contractors recommend roof deck ventilation, ceiling insulation and basically blocking or eliminating any heat source that will contribute to the high temperature in the attic and roof area.
You can also rake the snow off your roof, but it’s generally advised against by roofing experts for safety reasons. There are also heating devices available. Just make sure that they are compatible to use on your gutters. Whatever ice dam prevention method you use, it’s crucial that you consult your roofer first.
