Okay. Welcome to the podcast of advanced commercial systems. Humbled the roof nerves. We have been talking here, by the way. My name is Marty Grisham. I’m the owner, founder and operator of advanced commercial systems here in commercial roofing, broken era. We are absolutely excited to have you with us today. Another great podcast. We’ve been doing these for so long. I can’t even keep count, well over 180 podcasts that we’ve been doing and it has been exciting bringing these to you so that you can learn more about what we are, who we are, and commercial roofing in northeast Oklahoma here with advanced commercial systems. Today we’ve been talking, um, we, or our topic for the today is really once again a thermoplastic single ply roofs, thermo plastic, seeing single ply roofs like TPO and PVC. So these roof systems are voice. Basically we’re going to focus mostly on just these two right now for quite some time because these are the hottest items on the market right now. Learn more on commercial roofing Broken Arrow with us today.
So, for commercial roofing Broken Arrow They’re, they’re producing over 80% of the reroofing jobs that are taking place for commercial roofing Broken Arrow. So here with a vast commercial systems, we are professionals at the installation and repair of these rooms. So just give us the call if you’d like to learn more about them. Um, w we want to begin today. I’m going over some general information. Um, so here’s a question for you. Why would we consider, why would anyone consider a thermoplastic single ply membrane? Okay. Multiple reasons. Let’s, let’s hit some of the top ones. One is the weight. You might have a heavy roof, you might have multiple layers and might be a lot of machinery on your roof. The weight is definitely hands down. One of the greatest factors of this roof because it is literally a 16 meal product. So every square foot, I mean it’s so light. I can’t even tell you what one square foot weighs less than a pound.
It hardly weighs anything. It’s really amazing, an amazing product. And so for that being the case, uh, it is, uh, 61 thousands of an inch in thickness and it’s basically plastic. So imagine a Tupperware Bowl, the lid to a large Tupperware bowl is about what this stuff, ways. So just imagine a how good that would be to be on your roof. Now next thing, um, when there’s movement, you can uh, expected buildings to building roofs, to move and buildings to move because of hot and cold and different reasons. So these, these membranes are elastic. They have some elasticity to them and that allows them to be able to move and not just easily tear. I was on a built up roof yesterday that had just a little bit of movement and a crack went about 40 feet down the middle of the building where the building had been moving that way.
Ever taken place with a single ply thermoplastic roof because they can move with the roof and they have some stretchability some activity. Okay. What’s another point we have today here in commercial roofing? Broken Arrow when you to recover an existing membrane, this is the membrane. This is what you want to consider. So in the international building code, you’re allowed to have one layer on a roof and which you can still come and put a new layer over that you cannot cover two layers that are currently there. So if you have two layers, you might have the potential of taking off the top one and then putting a new second layer back on there. That’s actually within code. That’s actually within the international building code, a SPEC specifications and standards that are met now here at mass tours or systems on the roof nerds. We do that all the time.
We’ve done that. Oh at a $217,000 roof that we did that for a few years ago. Um, that was a really big one. It had a metal roof and we came in, put down some plywood, put down some materials that needed to be put down and basically fully adhered a TPO roof right on top of that thing. Making a second layer on the roof causes it to really be a great water type process. So that’s something that you can definitely consider when you’re recovering and existing membrane recovering is actually a part of a process. And the standards met by the National Roofing Contractors Association and the International Building Code. Um, and then what’s our last point we’re going to cover today of the general information of what’s, what is it about, what’s the good aspect of these routes with commercial roofing Broken Arrow? When you’re recovering a metal roof, it’s really great for that, which I just shared some of the aspects of that.
So let’s cover some of the characteristics of thermoplastic single ply roof. The first one that stands out is there repeatedly, uh, can be softened and heated and cooled off over and over and over again. So let me explain to you how we install one of these. We get a 10 foot layer, we put it down, we get another 10 foot layer and we put it down next to him with about a six inch overlap. That six inch overlap gives us space to put plates and screws down and then to do a two to two and a half inch seam weld. Now when I say, well, what I mean, we’re bringing a hot air gun up there and we’re melting these two plastics. They’re are designed to do this in commercial roofing broken arrow. We do this all the time. We’re melting these two plastics so that they can melt and go together and create the strength of more than just the normal plastic one sheet by itself.
You’re actually now joining two plastic sheets together and making one. It is a great process, but here’s the part about this. The welding has to be very specifically done. You have heat welders around 500 degrees that are doing the welding. You can’t have that heat welder too low. You can’t have it too high. If you have it too low. It’s not melting the membranes and causing them to adhere to each other. If you have it too high, you’re burning holes in it and you’re, you’re having a lot of melting, which is then causing bigger problems in newer problems. Now, the cool thing about this specific characteristic of TPO and other, you know like PVC, single ply roofing membranes for thermoplastic. The other aspect about this is that you can re weld it after it cools off and you can reload it later again after it cools off.
When it cools off. It’s almost like a plastic lid. You know, you put a ladder on it. You get the plastic lid to a Tupperware bowl to kind of get kind of kind of Gooey, take the lighter off, let it cool off. You can do it again and again and again. It doesn’t lose its value. It doesn’t lose its chemical composition when you had it, it happening with it. So what’s our next point we will talk about next point is this stuff is flexible. This stuff can have between a 25% and a 30% alone. Geisha, meaning the city of these roofs is absolutely amazing and that’s where you don’t get the cracking and the tearing that you’re getting with all the other tops of roofs like built up and mod bit and even metal roofs can have some issues along the lines of the roof moving. We are the best in commercial roofing Broken Arrow.
These roofs are plastic, they stretch. What’s the next point? They are so stinking light. These lightweight roofs way from 0.35 to 0.4 per square foot. So you’re one third of a pound to four tenths of a pound per square foot. That’s literally nothing in commercial roofing. Broken air. Okay, let’s move on to the, the, the, the four types or the three times. Um, the four types actually have different types of single ply memories. One is polyvinyl chloride, PVC polyvinyl chloride. You may have heard of punny, polyvinyl chloride in commercial roofing, broken Arrow because you had PVC pipes in your home. If you live in a building, you have PVC pipes in that building. They’re made of that white PVC. Sometimes they make them black, but as a white PVC product that can handle grease, can handle animal fats, can handle all this stuff and they just do not decay.
They do not degrade. They’re really a longterm great pipe. Well, these commercial roofing Broken Arrow are made out of that. The PVC, the polyvinyl chloride are made out of the same thing. Okay. What’s our next one? Thermoplastic polyolefin or thermoplastic Olefin or polyolefin known as TPO. This is the one that we’re referring to all the time. The one of the reasons why TPO is a little cheaper than PVC, so this is, it’s makes it to one the run to whenever you have 80 85% of the market wanting a new roof, it’s the one to show. Okay. The next one is ketone ethylene Ester, k e once again it is a roof called Ketone, ethylene Ester, k e. It is a great single ply roof as well. And then there are some PVC alloys, couple cup copolymer, alloy copolymer alloys, ethylene, inter polymer, e I p and beauty dean at Greylock Israelite Polymer, which is an in BP.
These roofs, you’d probably never will hear much about them. You’ll probably never see much about them. They are kind of few and far in between of what we ever see in the industry. We basically see tons of of of TPO and we see occasional PVC. So here’s the question of the day for you. Do you know between TPO and PVC, which route is the best to use on a restaurant here in commercial roofing? Broken Arrow restaurant roofs have tons of animal fat, and if you’ve ever been on a restaurant roof, you might be a little grossed out. There is tons of animal fat that come out the the cooking venting systems and literally blow black grease cooked grease on the roof. They are really pretty nasty PVC, just like the pipes in your kitchen sink, that grease can go down. PVC is the one product that can handle this grease and does not decay from the grease.
