Champaign roofing professionals encourage their clients to consider how much weight their roof can support before it collapses. A roof collapse is a catastrophic event that can damage the entire house, ruin a homeowner's possessions and put their life at risk.

A roof that has not suffered decay should be able to support at least 20 pounds per square foot of weight before it becomes stressed. In some parts of the United States where heavy snow is prevalent, snow loads are considerably higher, requiring the roof to stand up to a greater depth of snow accumulation.

Homeowners can evaluate their risk for a roof collapse by first looking at the snow and ice accumulation on their roof. The steeper the slope of the roof, the faster precipitation will fall off it. For this reason, homes in climates known for snowfall have a slope of three inches for every 12 horizontal inches of distance. Ice and snow will accumulate quicker on a roof that has a low slope or that has a flat roof over a porch. This is especially true during high winds.

Fresh snow, packed snow and ice all have different weights. With fresh snow, 10 to 12 inches is the same as 1 inch of water. Fresh snow will weigh approximately 5 pounds per square foot.

A roofing expert from Roofs By Rodger of Champaign IL would be happy to answer any question you have about windows or roof replacement.

Most roofs can endure at least 4 feet of freshly fallen snow before becoming stressed.

It only takes 3 to 5 inches of packed snow to equate to 1 inch of water. Packed snow weighs around 5 pounds per square foot. This means that 2 feet of packed snow could be more than what most roofs are designed to handle.

Snow can have an accumulated weight. For example, 2 feet of old snow plus 2 feet of new snow could equate to approximately 60 pounds per square foot, which far exceeds the capability of most roofs.

Ice is by far the heaviest form of precipitation. One inch of ice is the same as 1 foot of fresh snow. Just a few inches of ice may be enough to provoke a roof collapse.

If the snow or ice accumulation on a homeowner's roof exceeds what it was designed to carry, homeowners should take immediate steps to have the snow or ice removed. It is not advisable to go up on the roof and use a shovel to remove the snow. Instead, a snow rake that has an extension arm should be used. Better yet, homeowners could contact their roofing contractor and get recommendations on snow removal.
