T.P.O. Flat Roofing Installation

Thermoplastic Olefin (T.P.O.) Flat roofing is generally used for commercial properties. One of the main advantages of TPO roofing is it's heat reflective and energy efficient properties. This is mainly due to its stark white color. TPO can be installed to basically any scale with some of the worlds largest building utilizing TPO roofing systems - it comes in strips typically 40 mils to 100 mils thick with 6-12ft widths that are heat welded on site. TPO membranes combine polypropylene (plastic) and ethylene-propylene (rubber) to create a stable membrane that can last over 30 years. An advantage to TPO roofing is it's price, TPO is often one of the most economical options for a large low slope roofing area.

Another distinct advantage to TPO membranes is the simplicity of repairs - You simply cut out the effected region and weld a new piece in it's place. Thermoplastic materials are distinguished from thermoset materials in that there is no chemical cross-linking. These membranes can be repeatedly softened by heating or hardened when cooled. TPO membranes are produced by calendering with lamination, extrusion with lamination, or extrusion-coating techniques. TPO sheets are a blend of polypropylene and ethylene propylene polymers and usually are reinforced with polyester. TPO sheets contain colorant, flame retardants, UV absorbers and other proprietary substances to achieve desired physical properties.
