Types of Commercial Roofs and Roofing Materials
You are probably most likely familiar with flat-style commercial roofs and therefore likely to think that there are limited choices when it comes to commercial roofing installations. In fact, just as there is variety in residential roof construction, so too are there varieties in commercial roofing construction – perhaps even more. Depending on the needs of the business, the building, and the local environment, certain commercial roofs are more or less appropriate. So, let’s take a closer look at the most common commercial roof styles and the materials used in their construction.
Whether you are looking at flat or low slope roofs, there are essentially six classifications for commercial roofing. Keep in mind, that some buildings do not feature low slope or flat roofs, so this list isn’t exactly exhaustive. Nevertheless, for the vast majority or commercial roofs, you’ll come across these main classifications:
Usually known by the acronym “BUR,” built-up roofing is a tar and gravel roof. At its base are several layers of a flexible membrane that protects the building and contents from wet and otherwise damaging weather. BUR is great for affordability.
Metal roofing is made from a wide range of materials including corrugated steel, copper, aluminum, stainless steel, tin, and even lead. Metal obviously rusts, so these roofs must be protected in order to provide long-term protection. Generally coated with a protective surface layer, metal roofing is exceptionally durable and also very attractive. Additionally, there are few roofs that offer more advanced fire protection.
Modified bitumen roofs are constructed with fabrics that are reinforced with bitumen then cut into layers and applied to roofs. These roofs usually feature 2-ply systems that are easily maintained and repaired. With annual inspections and regular cleaning, modified bitumen roofing will last. It features optimal tensile strength for a flat roofing system which makes it a perfect choice for a roof that gets regular foot traffic.
Thermoset Roof systems are known as EPDM roofs. Durable, versatile, easy to install and maintain, these roofs are great for climates with high levels of ultraviolet light. EPDM roofs are made from a single-ply of rubber roofing material that stand up well in both hot and cold temperatures.
Thermoplastic polyolefin (TPO) and poly vinyl chloride (PVC) roofs are reflective and light weight making them suitable for all roofs while also offering exceptional energy efficiency. These roofs are resistant to damage from ultraviolet light as well as to damage from chemicals, bacteria, and other punctures or tears. These roofs are often found on buildings with food production as they also stand up well to animal fats and other oils.
Finally, green roofing systems represent an option to reduce the impact of global warming. Green roofs are constructed from live organic materials that promote better drainage and water management while also improving air quality and reducing heating and cooling costs.
