Low Slope Roof Systems

What is a Low Slope Roof?

What is FLAT ROOFing?

Low slope roof systems, also called flat roofing, are roofing systems with slopes less than three inches per foot fall (3:13 / 14 degrees and less). Low Slope/Flat Roof Assemblies require proper planning and design. Thorough investigation and evaluations should be completed prior to consideration of restoration or recovery systems.

Major Considerations for a Low Slope Roof:

  • Drainage
  • Geographical location
  • Building codes
  • Chemical release
  • Foot traffic

EPDM Single Ply Roofing

Ethylene propylene diene monomer (EPDM) is commonly called "Rubber Roofing" and is a thermoset membrane that requires tapes or glues in the seams. EPDM or rubber roofing has performed for many decades and has proven to be a long-lasting roof system. The attachments are ballasted, fully adhered, or mechanically attached.

TPO Single Ply Roofing

Thermoplastic Polyolefin, or TPO, is a thermoplastic membrane roofing system originally introduced in the 1990’s and has grown to be one of the most popular commercial and industrial installation. These highly-reliable, yet cost-effective roofing systems are fully adhered or mechanically attached. TPO membranes are also available for hybrid systems with multiple plies as well as fleeced-back applications.

PVC Single Ply Roofing

Polyvinyl Chloride (PVC) is a thermoplastic membrane roofing system and has a long history of performance. These systems perform well on roofs where chemicals, grease, and fat may be emitted onto the surface.

Modified Bitumen

Modified Bitumen, also known as "Mod Bit" roofing systems, are derived from modified asphalt. These systems are either SBS (Styrene-Butadiene-Styrene), which is a rubber modifier designed for elongation and recovery properties, or APP (Atactic Polypropylene) with a plastic modifier to provide a tougher weather resistant blend. Although expensive, hybrid systems utilizing modified bitumen with membrane as inner plies with single plies such as TPO, EPDM, and PVC fleece-backs as surfacing are also options. These systems are applied in multiple layers or multi-ply assemblies.
