TPO Roofing



TPO Membrane Roofing Systems

Thermoplastic polyolefin (TPO) is a single-ply roofing membrane created from ethylene propylene rubber. 

Manufacturers designed the system to combine the performance benefits of rubber with a hot-air welded seaming technology used with plastics. 

Presently, it is enjoying significant growth within the roofing industry. 

TPO membrane is most commonly installed in white for its energy efficiency benefits; however, it is also available in tan, gray and many custom colors. 

It comes in a variety of thicknesses ranging from 45 mil to 80 mil providing numerous design choices for various facility applications and budgets.

Outstanding Benefits

A Sentry-installed TPO membrane roofing system offers building owners and managers solid benefits for both new construction and re-roofing applications:

  • Heat welded seams for long-term performance – this method offers superior seam strength without relying on failure prone glue or seam tape.
  • White energy-efficient membrane reflects the sun’s harsh UV rays providing reduced cooling costs for air-conditioned environments and cooler working temperatures in non-conditioned facilities.
  •  A more comfortable working environment for your staff results in increased productivity.
  • Reinforced membrane with excellent abrasion, tear and puncture resistance.
  • Long warranty terms available for your protection and peace of mind.

Sentry Roofing Provides a Proven TPO Installation

Your TPO roof installation from Sentry Roofing may be mechanically attached or fully adhered. 

TPO roofing membranes are a rolled goods product and can be installed with sheets up to 12 feet wide reducing on-site labor and installation time. 

All seams and flashing details are welded on-site by Sentry’s experienced technicians using hand and robot hot-air welders.

This is an industry proven seaming technology avoiding adhesives, toxic fumes or open flame torches. 

Once completed, the installation creates a watertight, monolithic roof membrane with superior strength and performance.
