Sentry Roofing is utilizing the latest in roofing solutions for its commercial, industrial, and institutional clients. Thermoplastic Polyolefin (TPO) is a single-ply reflective roofing membrane made from polyprophylene and ethylene-propylene rubber polymerized together. It is typically installed white membrane to remain exposed throughout the life of the roof.

Standard TPO is available with an optional CLEAN Film, a temporary protective film factory applied to the top surface of the membrane. By protecting the membrane surface from scuffs and dirt accumulation during installation, this protective film can save labor and time by helping to eliminate the need for roof cleaning upon project completion. CLEAN Film can be left in place for up to 90 days. Durable and easy to remove, CLEAN Film helps to improve the aesthetics and long-term reflectivity and is ideal for use on re-roofing, re-cover and new construction projects.

TPO is Energy Efficient
White surfaces have been shown to reflect up to 78% of the sun’s rays to reduce air-conditioning costs. The excellence reflectivity of the white TPO even reduces the heat build-up under the membrane.

TPO has the best Lifecycle
TPO provides excellent resistance to fire, UV, airborne bacteria, and industrial pollutants such as air-conditioning coolants. Contains no chlorine, a plus for the environment.

TPO’s Strength
TPO keeps moisture out, yet is lightweight making it ideal for new construction and retrofit installations without adding excessive weight to the roof deck.

TPO’s Flexibility
The membrane remains flexible in hot and cold temperature so it will not split or crack.
