Single-ply membrane roofs are classified into four categories: metal roofing, EPDM, TPO, and PVC. Each substance has its own set of advantages and disadvantages. To help you make an informed decision, we will go over the characteristics of each material and the flaws that you should be aware of.
If your existing roof costs you a lot of money in repairs, it might be time to think about a metal roof. Here’s why.
Pros
The extended lifespan of metal roofing is at the top of our list of advantages. Many homeowners prefer metal roofing when upgrading their roofs or building new homes. They are also more eco-friendly, more fashionable, and more energy-efficient.
Cons
Metal roofs may be noisy; while some people enjoy the sound, it is nevertheless seen as a disadvantage of metal roofing. Second, a metal roof, if damaged, can cost more to repair than any other type of roofing system available in the market.
TPO
TPO is the market’s fastest-growing commercial roofing technology. It is composed of a single layer of synthetics and reinforcing scrim and is suitable for covering flat and semi-flat roofs.
Pros
It provides excellent resistance to ozone, UV radiation, and certain chemical damage at a low cost. Second, it reflects heat radiation more effectively than EPDM and is resistant to mold development, dirt accumulation, rips, impacts, and punctures.
Cons
To withstand the test of time, heat welding the seams necessitates a high-quality installation. Furthermore, some material formulations may not endure much longer than ten years, and newer technology results in a lack of demonstrated track record.
EPDM
EPDM, sometimes known as a “rubber roof,” is an abbreviation for ethylene propylene diene monomer and is named after the chemicals (monomers) blended in various amounts. It is most commonly employed on low-sloped or flat roofs, particularly commercial structures.
Pros
EPDM has the lowest pricing per square foot for flat or low-pitched roofs. Second, EPDM has a lifespan of more than 20 years and, because it is readily matched with polyiso insulation, it may be a very energy efficient roof solution, especially if ordered in white.
Cons
Ballasted EPDM systems are quite affordable; nevertheless, fully adherent or mechanical methods are slightly more expensive than TPO. It is often assumed that black flat EPDM roofs are not the most attractive sight.
PVC
PVC is another single-ply membraned roofing option used on flat and semi-flat commercial buildings, which stands for polyvinyl chloride. It has less oil and petroleum than TPO, EPDM, or metal roofing.
Pros
PVC’s strength allows it to survive for more than 20 years, and it is also resistant to chemicals and fire, and is also recyclable and eco-friendly.
Cons
Cost is one of the most daunting elements of a PVC roofing system. Additionally, PVC installation is difficult, which adds to the overall work cost, and it does not perform well in cooler areas.
To Sum It Up
EPDM is a low-cost material; however, it is more prone to damage and mold/mildew buildup and thus is not the ideal roof to consider.
TPO is another low-cost option that reflects solar rays and heat, making the structure more energy efficient. TPO is a newer invention on the market, and the judgment is still out on whether it will last as long as PVC, Metal Roofing, and EPDM.
PVC is the most expensive of the four single-ply membrane roofing we covered, but it is also a tried-and-true roof technology that is sturdy, durable, and environmentally friendly.
Since each membrane has its own set of advantages and disadvantages, there is no particular winner as to which roofing system is the best. It all depends on what the client demands.
