Flats Roofs That Fit Your Building

If you are new to commercial roofing installation, you may be wondering if commercial roofing options are similar to residential options.

The fact is that commercial roofing has little in common with residential roofing regarding materials, installation, slope and even the contractor you choose. Read on to learn more about flat roof options that will fit your commercial building and budget just right.

PVC Roofing

When you hear “PVC,” you may think of PVC pipes. However, one of the most popular types of flat roofs is PVC roofing. PVC stands for Polyvinyl Chloride. It is a proven, long-standing performer in the field of single-ply flat roofing.

  • Benefits: PVC is watertight regardless of ponding. PVC is available in a variety of colors, offers excellent reflectivity, and may be custom fit to your flat roof in one continuous sheet.
  • Disadvantages: The primary disadvantage of PVC is that its impact resistance diminishes with age.


EPDM (ethylene propylene diene monomer) is commonly referred to as “Rubber Roof” due to its resemblance to a rubber tire inner tube. It may be installed by fully adhering, held down by smooth river rock or being mechanically fastened.

  • Benefits: Rubber roofs are durable, impact resistant and enjoy a very long track record.
  • Disadvantages: EPDM is prone to shrinkage near the end of its useful life. It may suffer pulling away from edges and penetrations.

Modified Bitumen

Modified bitumen (MODBIT) is an asphalt flat roof with added modifiers which give it a rubber-like quality. MODBIT doesn’t need a gravel surface like EPDM, which may reduce costs for maintenance and repairs.

  • Benefits: MODBIT has a rubber-like quality, a proven track record and is available in 1-, 2- or 3-ply systems.
  • Disadvantages: Installation mistakes and seam failure can result in moisture infiltration.

TPO Membrane

Around since the late 1980s, TPO (Thermoplastic Polyolefin) is a relative newcomer to the commercial roofing industry. TPO roofing sheets are produced by calendaring or extrusion-coating techniques.

  • Benefits: TPO is UV reflective and available in many colors.
  • Disadvantages: TPO does not quite enjoy the long track record of PVC or EPDM.

The most important decision regarding choosing the right flat roof for your commercial building is actually choosing the right roofing contractor.
