In the 20+ years that TPO has been in the field, it’s become one the most popular products used for low-slope roofing. Over 1 billion sq. ft. are installed annually, making up over 50% of Singleply roofs being installed today. The rapid rise in popularity can be associated with several of TPO’s inherent benefits, including:
- Great Value… Excellent performance at a cost-effective price.
- Seam Strength… Heat-welded seams provide greater seam strength to taped and other seams.
- Long-term Weathering… Excellent long-term heat and UV resistance.
- Inherently Flexible… No need for plasticizers.
- Naturally Fungal Resistant… Doesn’t require biocides.
- Versatile Application Methods… Including high-performance roofs requiring high wind uplift, increased puncture resistance, or quick economical systems
- Energy Saving… Highly reflective and emissive white surface can help reduce energy costs and urban heat island effect. » Check out your potential energy savings by going with a white roof at cool.gaf.com
The Thick and Thin of TPO Roofing
Since its inception as a roofing membrane, Versico has led the industry in TPO research, development, and technology. Today, TPO is the fastest-growing segment of the commercial roofing industry, and with such a wide variety of membranes on the market, it can be difficult to know which one to choose.
Thicker TPO increases puncture resistance
Most rooftops have air conditioners, skylights, heating units and other penetrations that are added after the membrane is installed. In addition, this equipment can require upkeep, which leads to increased foot-traffic by maintenance personnel in industries other than roofing! Thicker membrane helps to protect against damage during construction and maintenance activities. 60-mil TPO provides 25% increased seam strength and 17% greater puncture resistance than 45-mil TPO membranes.
Make a small investment now, reap big dividends later
How much more does it cost to go with a thicker membrane? Not as much as you may think: For as little as a 4% increase in total installed cost, membrane thickness can be significantly upgraded. Thicker membranes are also eligible for longer warranties with enhanced coverage. Selecting a thicker membrane is a minimal expenditure that delivers a significant payoff. Return on investment is substantially improved, as increasing membrane thickness can extend the roof’s service life by as much as 33%.
Will a thinner membrane fatten your bottom line?
Sure, for now. But take a minute to think about why some of the country’s most savvy, bottom-line driven businesses, such as Walmart and Lowe’s, have switched their roofing systems from 45-mil to 60-mil TPO. A roof is not a short-term investment; therefore, in relation to its service life. Since its inception as a roofing membrane, Versico has led the industry in TPO research, development, and technology.

Protect your valuables with a thicker, stronger barrier
When evaluating roofing system alternatives, building owners must consider the operations and assets that their roof is meant to protect. Buildings are constantly under attack by the elements, and a rooftop is the first, and most important, line of defense. An increase in thickness can provide many extra years of performance and priceless peace of mind.
Thicker membrane increases weather resistance
All of Versico’s VersiWeld TPO membranes are enhanced with the OctaGuard XT™ weathering package, a patented blend of eight performance enhancing ingredients. As the sun beats down on a rooftop, the “reservoir” of weathering package protects the membrane’s surface from UV degradation and helps it retain its smooth, reflective finish. Because thicker membranes contain more weathering package per unit of surface area, they will perform longer with no change in surface characteristics. With 33% more weathering package than 45-mil membrane, 60-mil VersiWeld TPO provides excellent weather resistance and long term performance for as little as a 4% increase in installed cost.
Benefits of thicker membranes
- Improved return on investment
- Additional warranty coverage
- Increased wind uplift performance on certain assemblies
- Greater resistance to UV degradation – thicker membranes contain up to 77% more weathering package than thinner membranes
- Enhanced protection against damage – increasing membrane thickness provides better resistance to punctures and hail and 25% greater seam strength
- Stays smoother and glossier – because they contain more weathering package, thicker membranes maintain their high reflectivity and smooth surface longer than thinner membranes
PVC (polyvinyl chloride) single-ply membranes have been around for nearly 50 years, since the first installations in Europe in the 1960s. Since then, PVC membranes have quickly gained popularity in the roofing industry, and for the past 30 years have become recognized as a sustainable alternative for low-slope roofing systems. PVC is now installed on thousands of rooftops across the world and is known for its durability and resistance to damage caused by water, fire and puncture.
EPDM is a durable material that has significant physical property advantages, and warming benefits in northern climates. EPDM is still a major influence in the commercial roofing market.
Here’s a list of EPDM’s overall system performance benefits:
- Hail resistance
- Flexibility in low temperatures
- Thermal shock durability
- Ultraviolet radiation resistance
- Cyclical membrane fatigue resistance
