Commercial Single Ply Roofing

The commercial Single Ply Roofing System is favored for its watertight quality and a highly reflective surface that lowers cooling costs. A Single Ply Roofing System consists of synthetic polymer sheets that are particularly adaptable to commercial roofing projects. Mak-Lyn's roofing team in Houston, TX, delivers three types of commercial Single Ply Roofing Systems:

Ethylene Propylene Diene Monomer (EPDM)

The EPDM roof installation is a mix of two elements: ethylene and propylene. Both elements are derived from oil and natural gas. The prefabricated sheets measure 7.5' or 50' wide and are 40 mils or 60 mils thick. Liquid adhesives and specially-formulated tapes are used to seal seams. Membranes may be black or white.

Thermoplastic Olefin (TPO)

TPO membranes are made by calendaring with lamination, using extrusion with lamination, or by the process of extrusion-coating. The sheets are a mix of polypropylene and ethylene propylene polymers that are strengthened and reinforced with polyester. Hot air and heat welding are used to seal seams. Sheets are treated with flame retardants, colorants, UV absorbers and other proprietary agents to achieve the desired appearance and functionality.

Polyvinyl Chloride (PVC)

Polyvinyl Chloride applications are constructed of PVC sheets made by calendaring, using spread coatings, or with extrusion techniques. They're usually reinforced with glass fiber, polyester mats, or with scrim. The sheets are treated with plasticizers, stabilizers, and additives to increase flexibility and create a finished look. PVC membranes are available with a non-woven fleece backing on the underside of the sheet.
