The Dangers of Snow and Ice Accumulation in Freezing Temperatures

11/20/2019 (Permalink)

Extreme winter weather can cause more problems than just slick roads and slippery sidewalks. When snow and ice accumulate, it can become heavy and cause building damage, water damage or both.

Snow and ice can collapse roofs, especially on older buildings. Older buildings have a greater risk of corrosion, which can weaken its structural integrity and allow for intrusions. Newer buildings that have roofs made of light-weight metal, roofs that are flat, or roofs that do not have a lot of supports are more likely to give-in under the pressure of excess snow and ice.

Snow drifts on a flat roof that have projections, a lower roof, or other equipment can accumulate snow that has drifted with the wind. This can cause vulnerability unless additional strengthening supports are added. You should contact a licensed professional about safely removing excess snow and ice from a roof as these can become risky situations.

To help keep ice of roofs that are sloped, make sure attics are well ventilated so the snow on the roof does not melt and turn to ice. Melted snow and ice can enter a roof via the eaves and flat roofs can experience water damage if ice dams form and prevent water from flowing into drains on a roof.

Improperly sealed windows can be affected by built up snow as well. Ensure that basement drains, window wells, outside walls, and gutters are clear from clogging; 10-12 inches of fresh snow or 3-5 inches of old or packed snow equal 1 inch of water and 5 lbs. of pressure for every square foot.
