Whether you are in the process of planning your own commercial building or you have a building already that will need a new roof soon, it is worth it to get familiar with the options available. The typical commercial structure can have a somewhat unique shape and style compared to an ordinary residential structure, so some of the roofing material options must be unique just the same. The majority of commercial roofs have either a flat or low-slope layout, so roofing materials must be created and installed for proper protection. Here is a look at some of the most common types of commercial roofing materials.
Metal Roofing
Numerous types of metal roofing exist, and even though metal is common on residential properties, it works out well on most low-slope roofs on commercial buildings just the same. Metal may be in the form of metal tile sheets or corrugated galvanized steel, but you can find traditional metal roofing panels in copper, aluminum, or even stainless steel. Metal is a viable option for a lot of commercial buildings because it offers excellent longevity and affordable installation.
Modified Bitumen Roofing
Modified bitumen roofing is created with double layers of membrane that make up a high-tensile strength finish. The roofing works out on flat roofs and low-slope roofs, and it requires very little attention or maintenance after it has been installed.
PVC or TPO Roofing (Thermoplastic)
Polyvinyl chloride (PVC) and thermoplastic polyolefin (TPO) are two typical commercial roofing options. Both are crafted from forms of plastic, but they are incredibly lightweight and fare really well in harsh weather and direct sunlight. Both PVC and TPO roofing are sprayed in place as liquified plastic polymers that harden to a solid formation soon after application. Just like some roofing membranes, the roof can be touched up with new layers as needed.
BUR (Built-Up Roofing) Membrane
BUR, on the most basic level, is a built-up roofing material that is achieved with layers of fine gravel and thick tar. Typically installed on a low-slope roof, BUR roofing is considered to be both cost-efficient and effective for adequate protection. The number of layers can vary depending on the needs of the building, the weather in the area, and even how much money the property owner has to spend. The beauty of BUR is that new layer applications as old ones wear away can be less expensive than the initial install. Therefore, renewing the roof after the initial install is more affordable over the years.
