Whether it’s a commercial or residential structure, all flat roofs in Florida need to be virtually waterproof. If you’re due for a flat roof replacement, you’re probably exploring your material options. As experienced Florida roofers, we can tell you that single-ply roof membranes are worth seriously considering.
We’re PITCH Roofing, and we’re here to tell you everything you need to know about single-ply roofing systems. If you’re planning your new flat roof, keep reading for everything you need to know about these durable, Florida-ready roofs!
What Is a Single-Ply Roof Membrane?
As the name implies, a single-ply roof membrane is a rubberized membrane that installers roll out across your roof in a single layer. Since the 1960s, this approach has provided a flat roofing option that is durable, reliable, and easy to install.
On the surface, a single-ply roof membrane sounds like a flimsy roofing system. After all, couldn’t a single ply easily be punctured? But thanks to advances in roofing technology, even a single-ply roof is strong and resilient enough to withstand the Florida elements.
One of the most popular single-ply roof membranes is thermoplastic polyolefin (TPO). Made of different types of resilient synthetic polymers, these rubber roofs can withstand the worst that Florida can throw at them. The protective polymers stand up to puncture damage as well as water intrusions. These sheets of rubber roofing are heat-welded to the roof, so you can be completely certain that there is a water-tight barrier.
This about covers the basics of single-ply flat roofing. Now, let’s talk about the biggest perks of choosing a single-ply roof membrane for your new flat roof.
Pros of Getting a Single-Ply Roof Membrane
When it comes to single-ply roofs, there is a lot to love. Flat roofs have unique roofing concerns compared to sloped roofs, and a single-ply roofing system is perfectly tailored to the needs of low-slope roofs. Let’s talk about some of the biggest advantages you can expect from your new TPO flat roof!
Easy, Affordable Installation
In roofing, the more complex something is, the more it costs to install. That’s because complicated roofs require both more time and more experience. But with a single-ply roof membrane, you’re looking at an easy, cost-effective roof replacement.
Many other flat roofing systems build up multiple layers on your roof. This requires extra time and labor. But with a TPO flat roof, it’s all rolled out in a single layer. This faster installation can save you a good deal of money during your roof replacement!
Energy-Efficient
In Florida, we’re all looking to lower our energy bills, especially during the summer. And a TPO single-ply roof membrane can help you do exactly that. TPO usually comes in white, which helps it reflect UV rays and heat away from your structure.
It isn’t just the color that helps with energy efficiency, either. The polymers that make up a TPO membrane are inherently UV-reflective. While you can get TPO in darker colors, this reduces its ability to help cool your structure.
Durability
In a lot of ways, a single-ply roof membrane is perfectly suited to Florida’s climate. TPO is able to naturally expand and contract with the sun’s heat. While this may not sound like a huge advantage, it allows your roof to endure heat and solar rays in a way that would destroy other roofing systems.
Thanks to the heat-welded seams, a TPO roof is extremely durable and well-adhered to your roof. Even in the event that water gets trapped on your roof, it’s unlikely that your roof will start to leak. This is also a long-lasting roof installation method — that’s why TPO roofs last for 30 years on average!
Downsides of a Single-Ply Roof Membrane
No roofing system is perfect, and single-ply roof membranes are no exception. To help you make an informed decision, lt’s talk about the downsides of this roofing option!
Untested Roofing Material
In the past decade, TPO roofs have seen a lot of changes in their chemical makeup. These improvements should help your single-ply roof membrane last longer and require less maintenance over time. However, the technology simply hasn’t existed long enough for us to be sure.
Experts firmly believe that a TPO roof should last for 30 years. But unlike with other flat roofing materials, this option hasn’t been on the market long enough for us to be 100% sure how it will age. In this way, there is some level of risk in choosing a single-ply roofing system.
Degrading Seams
Heat-welded seams are one of the most secure ways to secure a flat roof. However, they may not stay strong throughout the life of your roof. That’s because Florida’s extreme heat can weaken the seams over the years, causing them to loosen and potentially allow water inside your roofing system.
For this reason, it’s important to keep up with regular roof inspections if you choose a single-ply roof membrane. While this is certainly a con, it’s hardly unique to TPO flat roofing systems. Florida’s extreme UV rays can damage any roofing system, so this is just a fact of life with roofing in the Sunshine State.
