Seeking the best commercial roof option for your needs? Can’t decide between a TPO or EPDM roof?
You can finally make your choice by learning more about each type. So let’s examine the specifications of each to make your decision easier.
What Does a TPO Roof Stand For?
TPO is an acronym of Thermo-Plastic-Olefin, which is produced by a concoction of propylene, polypropylene, and ethylene.
TPO is highly durable and a great choice for commercial property answers who wish to get a roofing structure that will do its job for several years to come. Note: they last on average more than 2 decades.
Despite the fact that EPDM has been leading in the sector for more than five decades, in the category of single-ply roofs, TPO has been growing in popularity over the past few years. This change in demand is attributed to a great extent to its simple set-up and energy savings. Hence, many experts predict that TPO will eventually pass EPDM in terms of popularity in the near future.
TPO, compared to EPDM’s dark exterior, is offered in a wide range of shade options to mirror sun rays and enabling HVAC units to function properly as they should, without leading to overburdening during the hot summer season.
Additionally, TPO offers more protection against specific types of deterioration. For instance, restaurant fans can release fats, gases, chemicals, and grease that can damage the roof’s outer layer. TPO differs by preventing these elements from ruining the roofing surface. Once installed, this roofing structure becomes welded, leading to an increase in the lifespan of the roof.
What is an EPDM Roofing Structure?
EPDP stands for “Ethylene-Propylene-Diene-Monomer” and is a roofing type made of an artificial rubber layer. It is structured to be applied over a low-curve flat roof and it enjoys high popularity because of its high durability.
If your commercial building is in a region that is often exposed to storms or hurricanes, EPDM is an ideal option to go for. The rubber layer enables the storm to deflect with minimal damage to the roof compared to a TPO system where a hail attack can ruin the outer layer if left untreated.
EPDM roofs are also proven to be highly functional, in spite of the fact that they use a single-ply and relatively thin layer. They also require less maintenance and fixing work than TPOs and in terms of costs, EPDM is on the same level of cost-efficiency as TPO roofing choices.
Which is The Best: TPO or EPDM Roofs?
Ok, let’s now dive into a quick comparison of these two. In terms of pricing, EPDM is a tad more affordable compared to TPO. It’s also a bit more durable and resistant to weather damage.
TPO is a tad more costly compared to EPDM, however, your choice ultimately boils down to the actual region of your commercial building and whether it is often exposed to hail storms, fallen tree branches, coastal winds, or hot sun rays (or not).
In any case, both roofing options come with their own perks. The final choice is up to you but note that an established roofing company can inspect the condition of your roof and find solutions to common roofing problems, depending on the type of the roof.
Commercial Roofing – It’s Your Choice
Now that we (hopefully) covered the fundamentals of both TPO and EPDM roofing, you’ll most probably know more about the subject to make an educated decision.
Both TPO and EPDM are common single-ply roofing choices with similar structures, however, each has its own set of perks and drawbacks. It depends on the target application and usage per industry.
Generally speaking, TPO is a better option in terms of energy savings and ease of installation. However, it is prone to damage in unfavorable weather conditions which may have an impact on the membrane and also tends to last 5-10 less than EPDM roofing systems.
EPDM is usually a less costly option that a roofer can set-up without needing any electrical power as it is mechanically bonded.
