When it comes to commercial roofing systems and residential roofs, they have primarily the same function — to protect the property. But…they’re actually quite different. The materials used to build and install each are very, very different, to say the least. Luckily our national commercial roofing experts are here to help review the differences in commercial roofing systems to help you to better understand your property, your building needs, and your options.
Typically, commercial roofing systems are made up of one of these materials; single-ply (EPDM, PVC, and TPO), modified bitumen, tar and gravel, concrete, and more. Residential roofs, on the other hand, are usually shingles, tile, or metal. As you can see, typically, more material options are available for commercial roofing systems and it’s important for property managers, engineers, facility personnel, etc. to understand the needs of their building and to partner with a reputable roofing contractor that offers extensive commercial roofing services so you can get assured results.
Commercial Roofing Systems
BUR Membrane (Built-Up Roofing)
Built-up roofing, also referred to as BUR, is the standard for the tar and gravel roofing system. This roofing system is comprised of a number of layers that enhance the durability of the system. BUR surfacing materials can be coated with paint or other reflective materials that can help to reduce the effects of US radiation. These coatings also provide the additional benefit of reducing cooling and heating costs. It’s a low-slope system and can be an ideal choice for buildings that need a durable, cost-effective roofing system.
Although used in the residential market as well, metal roofing systems are popular in the commercial roofing game as well. Metal roofs are offered in a number of materials, including stone-coated steel, metal tile sheets, copper, silicon-coated steel, corrugated galvanized steel, stainless steel, aggregates of aluminum, zinc, tin, and more.
Commercial metal roofing systems are not only durable, but they come with high fire-resistant ratings as well. Oftentimes, they carry protective layers that help to fight off rusting and help to fight off damage from exposure to sunlight and other environmental factors. Lastly, they’re quite pleasant to the eye as they serve as an attractive choice and can create a more sustainable design for any property.
Modified Bitumen Roofing (Mod-Bit Roofing)
Modified bitumen roofing (referred to commonly as mod-bit roofing) is made up of reinforced roof fabrics and bitumen in layers. These materials are fastened to rooftops as two-ply systems to enforce maximum stability and protection. Mod-Bit roofs can be easily maintained and offer improved tensile strength as compared to other commercial flat roofs.
EPDM Roof Membrane (or Thermoset)
EPDM (thermoset roofing), is a long-lasting and versatile system that is easy to maintain in comparison to other types of commercial roofing systems. These systems are constructed from a single-ply rubber material and comes with relatively simple installation. Thermoset materials solidify, or “set,” irreversibly after heating. These roofing systems have a strong resistance to ozone an ultraviolet light. Additional benefits of these roofing systems include flexibility in colder temperatures, resistance to some solvents, acids, and alcohol, and help to reduce cooling expenses.
PVC & TPO Roof Membrane (Thermoplastic)
Thermoplastic Polyolefin (TPO) and Poly Vinyl Chloride (PVC) roofs are a top choice for second-generation applications. Thermoplastic materials can be repeatedly softened when heated and hardened when cooled. These systems are resistant to UV rays, punctures, most chemicals, and bacterial growth, they’re lightweight, and they’re highly reflective. Both of these roofing systems are ideal for hotels, restaurants, and businesses that release any type of oil from the ventilation systems.
