Preparing Your Roof For Snow

Preparing Your Roof For Snow

Your roof is the first defender against all severe weather. For this reason, your roof should be prepared to encounter any predicted weather in the upcoming season. Accuweather predicts that frequent storms will bring the snowfall to above-normal for the Northeastern area of the US. It’s important to understand what the weight capacity is for your roof when it comes to snow. Most residential roofs should be able to support 20 lbs. per square foot of snow, unless your roof structure is damaged or decayed. In some areas on New England and in mountainous areas, snow loads could be greater, and the roofs tend to resist more snow.

Estimate How Much Snow Your Roof Can Support

Institute for Business and Home Safety provides us with the following comparisons to estimate how much snow is weighing on your roof:

Fresh snow: 10–12 inches of new snow is equal to one inch of water, or about 5 lb per square foot of roof space, so you could have up to 4 feet of new snow before the roof will become stressed.

Packed snow: 3–5 inches of old snow is equal to one inch of water, or about 5 lb per square foot of roof space, so anything more than 2 feet of old snow could be too much for your roof to handle.

Total accumulated weight: 2 feet of old snow and 2 feet of new snow could weigh as much as 60 lb per square foot of roof space, which is beyond the typical snow load capacity of most roofs.

Ice: 1 inch of ice equals 1 foot of  fresh snow.

If you feel your roof is in the danger zone after comparing amount of snows to the list above, you should highly considered removing the snow from your roof. For a safe removal, use a snow rake with a long extension that while allow you to remove snow while standing on the ground. If the task seems too complicated, hire a snow removal contractor.
