At some point in your life, if you ever owned property, you’ve probably come across the term “single-ply roof.” But do you know what it means when a roof is made of single-ply material? If not, or if you’re still not sure what this type of roof entails, we’ll explain in our own way so you can understand once and for all. The reason why it’s called a single-ply roof is because it is comprised of a single waterproofing layer or, in other words, “ply.”
As we find ourselves halfway through 2023, the TPO roof is gaining more and more popularity with each passing day. This is not that surprising, and we’ll see why as we delve deeper into the topic. Also, if your roof has suffered the aftermath of commercial roof damage or you’re just simply seeking preventive information, this blog might help you.
What Does TPO Stand For?
So, what is TPO roofing? Put simply, TPO is the abbreviation of Thermoplastic Polyolefin. This material is a form of single-ply roofing membrane that blends synthetics and reinforcing scrim. The TPO membrane is also laminated, which means that the top and bottom surfaces are not the same.
What Is So Special About TPO Roofing Material?
Even though single-ply membrane roofing materials can also consist of EPDM and PVC, TPO stands out above the rest. The hidden advantage lies in the fact that TPO roofing is made of a mixture of various materials, which allows the material to withstand harsh and extreme weather conditions.
Why Thermoplastic Roofing Membrane?
To better understand why you should opt for thermoplastic, let’s compare EPDM and TPO roofs. Imagine this; you’ve decided to buy an EPDM roof, and you start the installation process with hot air. After a while, you might notice that the material tends to change its shape, and therefore it cannot be joined by using hot air welding. This might pose a problem, but that’s why TPO comes into play, along with PVC, which cools down and helps regain the roof’s initial structure.
One more benefit includes resistance. This means that if you want to increase tear resistance, you’re in luck, because the majority of thermoplastic roof membranes incorporate a reinforcing layer known as a scrim that straightens the membrane.
How to Install TPO Roofing
Since the TPO roof is a single-ply membrane, it can be fastened easier and quicker, which is a huge benefit. There are three methods to fasten a TPO roof – mechanical attachment, ballast, and full adherence. Now that you know how a TPO roof can be secured, let’s look at the installation process:
Step 1: Purchase All Necessary Equipment and Prepare the Surface
You can’t start a project unprepared. Thus, make sure you have everything you need on hand before you start – measuring tape, seam roller, hot air gun, insulation boards, TPO membrane sheets, etc. After you’ve gathered all you need, remove any debris from the roof, dirt, or anything in the way. Also, don’t forget to check if there’s any damage. If there is, make sure to repair it.
Step 2: Install Insulation and Cut Vents or Pipes (if Needed)
Whenever you’re installing insulation, make sure to follow the manufacturer’s instructions. Another tip that might help is to apply the foam in both directions to spread it evenly. Regarding cutting vents and pipes, you might not have to do this step. This step should only be involved if you’re working on a new roof or restoration.
Step 3: Start the Installation of the Membrane
Finally, we come to the exciting part of installing TPO roofs. After you’ve done all the steps above, it’s time to roll out the TPO membrane. When doing this, make sure to leave the excess to overhang on all sides. Also, keep in mind that the surface should be smooth, without wrinkles or bubbles.
Step 4: Final inspection, Maintenance, and Care
As a final step, seal edges and flashing correctly to avert water infiltration. After the membrane installation, inspect the roof system and secure the flashing. Since TPO membrane requires minimal maintenance, ensure regular inspections, cleaning, debris removal, damage checks, and prompt repairs.
