When choosing a new roof for a commercial building in North Carolina it’s important to know which roof type would work best. Since many commercial roofs tend to be flat, allowing water to pool, you’ll need a roofing system that lowers your risk of water damage. This includes a good roofing design including tapered insulation and proper drainage systems. You’ll also need a roof that is durable and reliable enough to provide protection for a larger area compared to residential roofs.
Two of the more common types of commercial roofs that are available include thermoplastic polyolefin (TPO) roofing systems and ethylene propylene diene monomer (EPDM) systems. Knowing more about both of these systems will help you make the right choice for your commercial building.
TPO roofing systems have been growing more popular in recent years due to the benefits they offer. These roofs consist of one layer of thermoplastic polyolefin made up of different sheets. These sheets are heat welded together to cover your roof with a single membrane. When you have a TPO roof on your building, you can expect lower energy bills, improved protection from the elements and other benefits, including the following:
EPDM roofs have been the industry leader for commercial buildings for more than six decades. These roofs, which are made from synthetic rubber, are mechanically fastened, fully adhered and ballasted. EPDM roofs are commonly used for commercial buildings due to the following benefits they offer:
Although EPDM roofs offer these benefits, keep in mind that they typically have a dark surface. This darker coloring means that these roofs absorb heat from the sun rather than reflect it, which can make the interior of your building hotter. When you have an EPDM roof on your building, this darker surface forces your air conditioning system to work harder, resulting in more wear and tear, along with higher utility bills.
When it comes to choosing the right roof for your commercial building, climate and weather are important factors to consider. The amount of heat, rain and hail your roof is typically exposed to are among the biggest factors to think about when weighing your options. Since North Carolina gets a lot of heat and rain, TPO is the most suitable roofing system. With a white TPO roof, your building can significantly reduce cooling costs when it’s hot out. When it’s rainy, having a TPO roof provides your building with protection from water damage.
At the end of the day, design and details are the most critical part of your roof. This includes flashings, walkway protection mats, proper drainage, insulation value, and elimination of ponding water.
