Guest Blog: White Single-Ply Roofing Membrane for Your Next Project? Not So Fast!

September 06, 2016 15:56
Today, the majority of new roofing is a white single-ply membrane, either TPO (thermoplastic polyolefin) or PVC (polyvinyl chloride). This is due mostly to new energy codes that require reflective roofing to reduce heat absorption into the structure. Over the past several years we have investigated moisture build-up and damage to building materials occurring underneath this type of roofing on numerous occasions. The purpose of this article is to get the word out that night-time radiant cooling environments are causing detrimental moisture conditions affecting white single-ply roofing systems.

One of ERA’s overriding goals is to ensure that our members’ EPDM products are used in the most energy-efficient manner.

The logic seems so black and white: white roofs are cool and black roofs are warm, therefore a white roof is better in a hot climate and a black roof is better in a cold climate. However, the logic begins to break down as one considers the application of cool roofs in the less obvious conditions of northern climates where the right answer becomes increasingly “gray.”
