Flat Roof Types: Which is Best?

We receive a lot of requests for single-ply roofing membranes that can both stand up to the elements and provide years of reliable protection. Here are some of the very basic facts about three flat roofing types and how they measure up to each other.

Commercial Roof Types 

Thermoplastic polyolefin (TPO) and polyvinyl chloride (PVC) roofs have been around for years and provide commercial property owners with that rare combination of energy efficiency and heat-resistance.

Property owners looking to overhaul their buildings with a low-slope roof that doesn’t make concessions in terms of price and long-range durability also go with ethylene propylene diene terpolymer (EPDM) single-ply roofing membranes.

Below we’ve provided a breakdown of how each of these commercial roofing materials does head-to-head against one another on metrics that property owners care about.

TPO Roofing

The punishing Texas sun often requires you to retrofit your existing roof with an energy-efficient yet affordable alternative.

Fortunately, TPO roofs resist both heat and UV rays. TPO roofs are usually more affordable on a square foot basis when compared with PVC and EPDM roofs as well.

TPO is very easy to install even on hot days and repels mold, dirt and other age-accelerating factors that can corrode commercial roofs.

Compared to other single-ply roofing membranesTPO roofs can withstand Texas’ UV rays and remain resistant to thermal expansions.

TPO has drawn some concerns, though, when it comes to thermal loading and its yet untested track record, since it is a relatively new material compared to PVC.

PVC Membranes 

PVC roofing has been along a very long time and has a great track record for reliability. PVC can resist heat, dirt and high winds without losing its integrity. A PVC membrane can last a generation or more without any need for repairs.

This is actually quite startling, since many singly-ply membrane roof types need to be overhauled or touched up every fifteen years or so.

PVC comes in a huge variety of styles, colors and thicknesses to match your needs. Since PVC tends to be quite slick, though, it poses an additional safety concerns to workers already adhering to OSHA standards and regulations.

EPDM Roofing

EPDM roofing is environmentally friendly and waterproof. In fact, the 50-foot-wide sheets of EPDM can be quickly installed by our professionals.

EPDM is lightweight, affordable and incredible durable over time, and can go half a century without replacement!

There is no “perfect” roof type.  Each has its own benefits and flaws – and some manufacturers provide better products than others.  If you are looking for the right flat roof type for your business, talk to one of our specialists at BELDON® Roofing Company.
