5 Types of Commercial Roofing Options and How Denver Roofers Ensure Safe Structures


August 10, 2016

Whether you are moving into a new commercial space, or need to make some upgrades to your current ones, it is important that your roof is a reliable structure. It protects you and your customers from the elements and is one of the most crucial structural pieces of your building. Ensure your roof is safe and learn about the different types if considering an upgrade for your business.
  1. Built-Up Roofing: If your building has a flat or very low-sloped roof, a built-up roofing option may be your go-to when ready to replace your roof.  Then there is a small ledge that goes along the surface. According to the National Roofing Contractor’s Association “Built-Up Roof (BUR) Membranes” article, this type of roof is typically known as a “tar and gravel” roof. Built-up roofing has several layers to protect the building from the elements. Each of those layers uses asphalt to keep them together. To reinforce, the National Roofing Contractor’s Association explains they use roofing felts or ply sheets as reinforcing fabrics. They are reinforced with glass-fiber or organic mats. Also, they explain this roof type often uses aggregate of some sort on the top. So for instance, they may use gravel or mineral granules.
  2. APP and SBS Modified Bitumen Roofing: Atactic polypropylene and styrene-butadiene-styrene roofs, known as APP and SPS roofing for short, this type of roof also uses asphalt roofing for reinforcement. Once the asphalt is applied, it is essentially an advanced version of a built-up roofing system. You can expect the same benefits—and then some. This is great for areas that need flexibility with temperatures as it can adapt to the elements well. In Inspect-A-Pedia’s article “Modified Bitumen Roofing Types, Product Sources, Installation, Defects, Repairs,” this method is also common on flat or low-sloped roofing applications. They explain installation can vary and includes hot applied, cold applied, heat weldable and self-adhered. Your roofer will be able to determine the best application.
  3. Self-Adhering Modified Roofing: Another great option for flat or low-sloped roofing is self-adhering modified roofing—also known as SA roofing. It is a popular roof repair or new project as it is a cleaner and easy to maintain roofing solution. Unlike some of the other types, heat and asphalt is not used. This option is becoming increasingly popular for it’s simple and clean methods.
  4. Ethylene Propylene Diene Monomer Roofing: Also known as EPDM roofing, this style of commercial dates back to the 1970s. It is one of the tried and true methods that is still requested by companies to this day. This roofing type is incredibly resistant to inclement weather from storms to extreme temperatures. You can learn more about this type of roof in the ERA Roofing Association’s article “What is EPDM.”
  5. Thermoplastic Polyolefin: This type of roofing structure, also known as TPO, is a single-ply material designed to save businesses. It is one of the newest and most effective roofing solutions that can endure the elements. When looking for long-term solutions, talk to your local roofer to see if this option is best for you.
