How Heat Can Affect Your Commercial Roof
Weather can have many negative effects on your commercial roofing. Hail can dent the roofing, rain can lead to pooling water, which can lead to leaks, and ice dams can cause your roofing materials to crack. However, one of the most overlooked weather element that can damage your roof is the summer heat. Heat can be just as damaging to your roof as hail and ice, though few people realize it. Here are a few of the various ways that heat can negatively affect your commercial roof.
Heat Can Cause Cracks and Surface Damage
When it is hot outside, your roofing material expands. When the temperatures outside begin to cool off in the evening, the roof begins to contract. While it doesn't expand and contract enough for you to physically see it getting larger and smaller, this constant expansion and contraction process that takes place in the summer can take a toll on your roof. Over time the roofing material loses some of its elasticity and it does not expand and contract as it should. Instead, it begins to crack and surface damage presents Fasteners.
Heat Puts Pressure on Fasteners and Seams
Another problem that can occur thanks to the constant expansion and contraction that takes place on your roof during the summer months is more pressure is put on the fasteners and seams. This causes these items to split or break away. Unfortunately, seams and fasteners are designed to hold your roofing in place and prevent water from seeping into the roof. When the seams split open or the fasteners begin to loosen, water can seep through your roof during the next rainstorm.
Heat Can Lead to Moisture Build Up
The last issue caused by heat in the summertime is moisture build up. On commercial buildings, the air conditioning unit is typically mounted on the roof. During the summer months, you likely run the A/C often. Water and condensation may drip from the unit and the hoses directly onto your roof. Moisture can lead to mildew on your roof or can weaken your roofing materials in the same way rain can. You should always have your air conditioning unit inspected to ensure that there are no excessive leaks prior to using the unit for the summer to minimize the amount of moisture build-up as much as possible.
