When constructing a new commercial building in an area with harsh winter weather, it's important to choose the right building materials for its roof. Not only does the roof need to be water-tight, but it also needs to be able to stand up against many decades of pounding rain, wind, hail, and snow.
There are four different types of commercial roofing materials you should consider installing on your building to withstand cold climates, including:
One of the most popular commercial roofing materials is a type of asphalt called modified bitumen. This roofing material gets the "modified" portion of its name from the fact that the asphalt is fortified by adding plastic polymers or rubber compounds. This simple and inexpensive modification makes the roof much more effective at reflecting the sun's rays in the summer. During the winter, it helps prevent cracking when the roof is subjected to freezing temperatures and snow. Modified bitumen roofs are energy-efficient and have an average lifespan of a few decades, making them a solid choice.
Ethylene Propylene Diene Monomer (EPDM)
Second in popularity to modified bitumen commercial roofs are those made of ethylene propylene diene monomer (EPDM). While its name is a mouthful, EPDM is simply a chemical name for a synthetic rubber product. If your building is in an area with both really cold winters and very hot summers, then EPDM is a better option than modified bitumen because it is more elastic and handles both hot and cold weather like a champion.
Thermoplastic Polyolefin (TPO)
If your goal is to erect a building with maximum energy efficiency, then a thermoplastic polyolefin (TPO) roofing system is the best option. TPO is a fancy name for a single-ply material that is laid down on the roof and then sealed in place. TPO material is very strong and able to withstand any weather without damage. In addition, this type of roofing material is highly reflective and this will keep the building's interior warmer in the winter and cooler during the summer.
Last but not least, another good choice for your new commercial building's roof is to use metal. This option is great if your roof has some slope to it and snow is a constant companion all winter. Metal roofs allow the snow to slide right off of them and greatly reduce the amount of snow removal you will need to do manually.
