Understanding exactly what components go into a commercial roofing system means we are well placed to identify what work needs to be done swiftly and efficiently. Amongst the types of commercial roofs we regularly encounter is –

Low-Slope roofing

Low-slope roofing is the most common form of roofing for commercial industrial buildings, there are different methods used to create a durable low-slope roof but all of these systems must follow three key principles.

  • Weatherproofing layers must be included in the design of the roofing system to ensure that it is waterproof and durable during all weather conditions.
  • Reinforcement is needed to add strength and stability to the structure. This should also make the roofing puncture resistant.
  • Surfacing must be used as an extra layer to protect the weatherproofing and reinforcement layers from sunlight and water. Some surfacing layers have properties that give the roofing increased fire resistance, hail resistance and increased solar reflectivity.

BUR (built-up roofing system)

This type of roofing system is commonly referred to as a tar or gravel roof. It is made up of layers reinforcing fabrics that are bonded together and made waterproof using hot asphalt (bitumen). The more layers that are formed, the more superior the quality of the roof as this makes the roof membrane thicker and more durable.

APP and SBS modified bitumen

Over the years, technological advances in asphalt sciences have led to the formation of APP (atactic polypropylene) and SBS (styrene-butadiene-styrene). These are modified bitumen that when added to unblown/unoxidised asphalt, impart plastic (APP) or rubber (SBS) characteristics. This gives the asphalt enhanced performance characteristics compared to traditional asphalt.

APP and SBS can be mixed with reinforcements such as polyester or fiberglass to create a strong, high-performance roof membrane. APP is self-adhering when heated using a roofing torch whereas SBS can be formulated in this way but is more commonly applied with hot asphalt or cold SBS modified bitumen adhesive.

Using APP and SBS gives the same result as a BUR commercial roofing system but has enhanced performance capabilities. Both types of roofing are a good choice for a low-slope industrial building. Deciding which roofing system to go for can be influenced by factors such as site access, structural load, finished appearance, desired warranty and performance criteria.
