If treated correctly, your roof could last anywhere from twenty to fifty years. Simply lasting is not a measure of roofing success, however—instead, you’ll want to look at lifetime costs. Picking the right commercial roofing materials up front, treating them properly, and investing in the correct infrastructure and maintenance programs will make your roof more efficient and more likely to last its full lifetime without incurring significant costs. Defining and Creating an Efficient Roof As far as the efficiency of your commercial roof is concerned, there are three main considerations you should take into account. First, you want it to have a low up-front cost Second, you want it to have a low energy cost Third, you want it to have a low maintenance cost In other words, a good roof will be relatively inexpensive up front and relatively easy to maintain. In addition, it will provide a good seal for your building envelope, prevented cooled or heated air from escaping. What does this roof ...

Winter is approaching across the Northern Hemisphere, which means it’s time to prepare for thermal expansion—and its more dangerous cousin, thermal shock.  Thermal expansion is an inherent property of matter. When materials get cold, the molecules that comprise them slow down their vibration and contraction. At the scale observable to the human eye, this presents itself as shrinkage. When materials warm up, they gain energy and expand. When materials are exposed to repeated cycles of expansion and contraction, they tend to lose their flexibility and accrue damage over time—and this damage could occur to the materials in your roof. There are several factors that make thermal expansion more of a risk around this time of year: We’re moving from a period of general warmth to a period of general cold. The materials that comprise your roof will shrink, which makes it possible for gaps to open up between membranes, flashings, and penetrations—promoting leaks. If your roof has existing wat...
