Commercial Flat Roofs
Flat roofs are a popular option for commercial roofing. The 5 common types of flat commercial roof include:
- Built-Up Roof Systems
Also referred to as BUR and sometimes tar & gravel roofs have been used for commercial roofing in the U.S. for over a century. The built-up roofing system contains fabrics and alternating layers of asphalt. You get to pick how many layers you want to be installed since these layers can be as many as 12 layers. The last layer of a built-up roof system will typically consist of gravel.
The great thing about BUR roof systems is that since layers are used, if one layer breaks down, there are other layers for protection. These types of roofs have incredible benefits such as high puncture resistance, thermal shock resistance, impeccable membrane toughness and strength that makes the roof a great option for long-term durability. While BUR roofs are quite heavy due to the types of materials used, they offer the cheapest flat commercial roofing option.
- Standing Seam Metal Roofing Systems
The standing seam metal roofing system also known as low slope structural metal roofing system is applicable for low slope construction. Metal roofs are light as compared to built-up roofs since they are made of corrugated galvanized steel. Metal roofs are often used for commercial roofing since they can resist high winds, are easy to install and have high impact resistance. During installation a standing seam metal roofing systems require a machine seeming to help crimp the panel seams. They offer great value for money since they are environmentally friendly and will even last a lifetime.
- Spray Polyurethane Foam-Based Roof
This is an environmentally friendly roofing system that is in liquid form. After it is sprayed, it expands and becomes a foam that eventually creates a solid layer which becomes the roof. Spray polyurethane foam roofing systems are also used in industrial facilities. The substrate containing single-component asphalt, hot and cold polymer-modified asphalt and two-component urethane elastomer must be rigorously prepared to create quality liquid for the roofing.
- Commercial Grade EPDM
Also commonly referred to as TPO roofing. It has become quite popular in the recent year for commercial buildings partly because they are affordable and long lasting. The roofing system comprises of rubber, saw dust and other synthetics. EPDM (Ethylene Propylene Diene Monomer) roofs have a proven ability to resist the damaging chemicals found on roofs as well as the effects of sunlight. Commercial grade EPDM is available in black and white allowing you to pick the white option during summer to save on the building’s cooling costs.
- Modified Bitumen Roof Systems
Modified bitumen membrane is made of asphalt (or bitumen) that is modified using rubber ingredients to increase stability, flexibility and strength. Typically, there are two modifiers used to create modified bitumen: APP and SBS. Atactic polypropylene and styrene butadiene styrene are the polymers added to the bitumen.
The Benefits Of Commercial Flat Roofs
– Flat roofs can be quite affordable to install as compared to steep roofs since the area covered is smaller. Therefore, if few square feet are covered, fewer materials are used hence allowing one to save.
