How To Calculate the Snow Load of Your Roof

Published by mercualiz fertina on

While winter is on the way out across the US, there are still some locations experiencing some spring snow. Snowflakes may be light but pack them on with several inches to feet and they can be super heavy. Winter storms can leave behind feet of snow weighing down your roof. Make sure your roof can handle this coming winter’s snowfall with the right roof.

Load Calculations

A roof snow load calculator came into being in order to help roofers put the right roof on a home that sees snowfall regularly. A roof collapse due to heavy snow is not what most homeowners envision their white holidays bringing. The roof’s snow load is calculated at pounds per square foot. In addition, the pitch of the roof is taken into account when calculating snow pressure. Pitched roofs are better in snowy areas than flat roofs.

Evaluation Considerations

When calculating the snow load, a few factors should be considered. Wet snow weighs more than dry snow. Roofing materials, how the roof is braced, the roof design and the layout geometry all affect the roof’s ability to hold up beneath pounds of snow. Proper maintenance can keep the roof performing as designed. Snow density and depth all affect the pressure exerted on the roofing materials. Snow retention should also be taken into account as wind and the sun help remove the snow from your roof.

Other Buildings

Snow load should be calculated for any buildings on the property. Outbuildings such as storage sheds and barns also need a roof that can withstand the expected snowfall in your area. Replacing these roofs can be as costly as replacing a collapsed home roof. The one difference is that you don’t live in them.

Save yourself the trouble of a collapsed roof from too much snowfall. Northern locales expect to see snow every year. Make sure your roof is ready to withstand the winter weather. Keep the warmth inside and the beautiful, white winter outside.
