Cold temperatures have a tendency to make our bodies brittle, and the same goes for the roofs over our heads. Along with winter weather comes many stressors for residential and commercial roofs. Before the season hits, be sure to have your roof inspected (if you haven’t already) and familiarize yourself with some of the things that commonly happen to roofs as a result of the season.
Thermal shock refers to when components of an object expand and contract at different rates and amounts. This can be due in part to many things, including a combination of materials that have been assembled together… for example, a roof. With wood, shingles, and metal together, thermal shock is nearly inevitable.
The expansion of these materials at different rates leads to cracking and damage on a roof. Combine the cracks with ice, snow, and moisture and the damage increases. This is why the winter months are especially harsh on your home or building’s roof.
Ice dams occur when ice builds up and blocks off the places where melted ice and snow should drain. This can cause pooling which is definitely bad for a roof. Water can also travel underneath these dams leading to areas where it can cause leaks to occur. Before the snow and ice hit, make sure your gutters are cleared of leaves and other debris so there’s a lesser chance of these frozen dams.
The combination of a large amount of snow and wind can easily lead to the uneven distribution of snow on a roof. With the heavy weight on one part, you might be concerned about how that section of your roof is faring under the literal pressure. If you feel as though this is a major issue, contact a roofing professional who can help without damaging your roof in the process. Although you may be tempted to do some problem solving yourself, you shouldn’t risk further damage to the roof or injury to yourself.
