Effects of Weather on a Commercial Roof

Effects of Weather on a Commercial Roof

Effects of weather on a commercial roof vary throughout the seasons. During summer, a heat wave washes across the country and people head inside and crank the AC. Come winter, most places face cold, rainy weather and people once again head for the indoors, this time for the heat. This is especially true in Chicago and the surrounding areas; the weather here can be extreme. Long, cold winters with a lot of precipitation, snow, moisture and hot, blistering summers with close to 100% humidity nearly every day takes its toll on commercial roofing in Chicago. Let’s look at some of the weather Chicago faces, and how that wears down commercial roofs.

Summer Effects

Heat alone doesn’t do much beyond put your air conditioning units into high gear. This can cause secondary wear to a commercial roof though, because the more that the units are used, the more they break down, and the commercial roof then faces increased foot traffic from maintenance crews and technicians. Intense UV rays from the sun can cause damage, though, weakening seals and bonds. The biggest source of stress from summertime is humidity. If there’s one bane to the existence of a roof, it’s humidity. Humidity weakens all structures of a roof, and moisture can build up and start to affect other parts of the commercial roof, from wood rot to mold.

Winter Effects

A commercial roof faces similar wear and tear come winter, but on the opposite end of the spectrum. Snowfall, wind, sleet, these can stress a commercial roof quite a bit, depending on the severity. Snow can stress the weight limits, wind can cause uplifting, and an ice storm can quickly make a roof dangerously close to weight capacity. Because it’s cold outside, people take shelter in the warmth of indoors, and heating systems need more maintenance and repairs, again causing foot traffic on the roof to increase.

In those graceful in-between months, your roof gets a bit of a break, (and so do you). Any roof still faces some stresses though in these seasons. Autumn can bring falling debris, leaves, branches, plant matter, all of which can cause damage to a commercial roof. Springtime can be extremely wet, and it doesn’t need to be said twice how humidity is the great enemy of all roofing.

    You are right about the challenges posed by the extreme weather to the roof, but these can be overcome to a great extent by choosing the right roof for your weather, a good roofer and inspecting your roof atleast twice a year during spring and fall.
