Many commercial facilities have EPDM or TPO roofing. Both options offer protection against the elements, particularly for flat roofs. Below are a few facts about each product to help you choose between them.

What Is TPO Roofing?

Thermoplastic polyolefin (TPO) roofing is made of single-layer sheets welded together to create single-ply membranes. In addition to offering top-notch protection from inclement weather and debris, TPO is durable and lasts for up to 30 years when installed correctly and maintained regularly. Cleaning is simple; sweep away debris and use a low-pressure stream of water to wash away grime every season.

The material is also unlikely to sustain punctures from impact. The welded seams don’t contain glue, making them less prone to separation between panels than other options. TPO resists bacteria, algae, and even chemical exposure. It also shields your building from water since the surface repels moisture. TPO even reflects sunlight, creating an energy-efficient covering that keeps internal temperatures moderate during the summer.

What Is EPDM Roofing?

TPO roofingEthylene propylene diene monomer (EPDM) roofing is made from synthetic rubber and has been a traditional choice for commercial roofing for decades. During installation, a professional manually fastens and glues the material to the roof. The surface lasts for up to 60 years and is beneficial for the environment since it often contains recycled materials.

This type of rubber resists hail damage and, when well-maintained, is water-resistant and strong against the effects of ultraviolet (UV) rays. Sweeping away debris and hosing down areas with clean water every few months is enough to keep it clean.

Since this material is flexible, it’s a common choice for buildings with several roof features, including pipes, skylights, and vents. EPDM roofs are typically dark, which means they absorb the sun’s heat instead of reflecting it like TPO roofing. However, lighter colors may be available to offset heat absorption.
