Well, it’s another wonderful day here did, that’s commercial systems. Another podcast that we’re doing concerning commercial roofing in the Greater Tulsa area and specifically here in Tulsa, Jenks, Waso, sand springs, Claire Maurer, Katusa Bixby and good old commercial roofing, broken arrow. So here at commercial roofing, broken Arrow, we specifically, I spend a lot of time talking about the different aspects of commercial roofing, the different systems, the different types of products to be used. You know, staying on top of product knowledge is really a big part of our industry. Um, and also on top of different types of roofing systems, you know, you have a roofing assembly and you have a roofing system. And Lot of times I use the word roofing system because our company is called an advanced commercial systems. I use the word a roofing system sometimes when it’s really, it should be referred to as a roofing assembly.
So I’ll take a check, just a second here to explain to you the difference between the two. Our roof assembly or roofing, this Emily is basically the entire roofing system, including the decking. So from the bottom of the decade all the way to the top of the upper membrane, that is the water tight membrane of the roofing of, of the roof. That specifically is a roof assembly. A roofing system is everything above the decking all the way to the top of the membrane, the water tight membrane at the top of the roof. And so basically when you take the decking out of a roofing assembly, you’re basically coming up with a roof system. And so, but I like to refer to the the roofing system because we are advanced commercial systems. We are the home of the roof nerds. And so if I was made the company advanced commercial assemblies, no one would do it in the world we were talking about.
And so here at advanced commercial systems, home of the roof nerds, we love to talk about roofing from the bottom of the decade all the way up. Now the reason for that is because many times we are having to replace decking. That’s gone bad decking. This had damage and issues. Sometimes decking is worn out because rust and deterioration has worn the decade out. So because of that, we oftentimes talk about the roof decking just as much as we do the roofing system above the decking. And so today I want to talk about one specific type of roof system that um, and it’s not really one type, but it’s a specific type called aggregate. Now let’s define first what exactly aggregate is. Um, aggregate is a, a low density, uh, w if you have light, lightweight, aggregate light, aggregate is a crushed stone or crushed slag, or sometimes we’re using a, so the types of aggregate, um, you know, between crushed stone, crushed slag, uh, and water worn gravel, so worn gravel, these are the three that we see the most.
Uh, I like the water worn gravel because they’re normally not as sharp and I like for the, the membrane to be taken care of. Um, so also an aggregate can be defined is, you know, a type of granular mineral material or any type of that. So, so within a aggregate, so I’m sharing with you basically if I could just make it simple. Gravel roofs. So what exactly all is involved in aggregate. So aggregate is basically the gravel are crushed stone, that roof con, uh, like myself and advanced commercial systems here in commercial roofing, broken Arrow that is gravel that we can put on a roof to protect them and Brian to be part of the roofing system. So what’s the purpose in the gravel? So some people say, well I know the purpose and the gravel it very easily. It’s just basically, you know, to protect the gravel, to protect the roof membrane from sun and from hail and stuff like that.
And I would have to say absolutely correct, but that’s not the only reason. The one of the reasons why we commercial roofers use aggregate in commercial roofing is for the fastening or the uh, installation purposes of the aggregate. So let’s talk about the two main types of aggregate or the, I’m sorry, the two main types of installing and fashioning a roofing system. So let’s just take [inaudible]. You can take EPBM or TPO or PVC and you can install that with mechanical fasteners, these long screws and plates that screw through all the substrate, all the installation that screw into the decking. And so when you do that, that fashion is the roof down. So that high winds does it lift it off and cause damage. But there is another way of fastening that’s very popular and that’s called Ed hearing the membrane. And you have adhering the membrane or fully yet hearing the membrane.
And that just depends. That just means that the ad hearing means that you’re actually gluing the product down. You’re using a commercial roofing adhesive that specifically designed chemically to work with a specific group that you’re using. So here at advanced commercial systems, uh, here in commercial roofing broken Arrow, these are the things we do every single day with, with commercial roofs and commercial roofing systems. And so we are one of the top commercial roofing contractors around. Uh, we are a commercial roofing contractor that’s second to none. And then also just for being a commercial roofing company, we really love to be above all other commercial roofing companies and really show how we stand out. So as far as getting into, uh, the different types of how the different ways that aggregate is being used, one of those. So we’ve just covered two types of two ways of fashioning down your, your top membrane that could be mechanically fastened with plates and screws or that can be adhering it with a basically a commercial roofing glue that’s specifically designed to work with that specific product, the product or the upper root membrane that you’re using.
But there is a another way which is hardly ever talked about by people who are not in commercial roofing. And that is using aggregate as a way of fastening and holding down your upper membrane. So let’s say you put down a TPO roof, you can take aggregate and lay it on that TPO roof. And when you do, so you’re basically weighing it down and that causes it to stay down for wind. High winds comes. So it is completely different than fascinate where you’re drilling through the building. Now there are some challenges with, with mechanically fascinating a product. Now, although it is the most least expensive form of fascinating in it down, um, because the labor cost is much less as opposed to bringing it up, you know, 1000, 2000 bags of gravel or, or, or pumping gravel up through a tube. And so there’s a lot of different ways that we do this with mechanically fastened, uh, products.
And so the one thing that we have to keep in mind is when we drill through that mechanically fastened screw, when we drill it through the roof, through the decking, there is the chance of causing problems below decking. There’s a chance of causing problems or there might be a pipe, there might be some conduit with some wiring. There is a possible chance of having some issues. And which I ran into that with a residential roof, a company I was working with years ago, they did that and they, they call some of mechanically, it’s just some mechanical issues with an Vac because the uh, lines were running right under the roof decking. Well according to Code, that should have never been. We know code is basically saying that the line should be considerably less. Other than that, you know, more than more than just a few inches or more than just an inch and a half below deck.
And so what we do with every single day is, is always trying to weigh out which is the best fastening or the installation procedures and processes. And many times if the building permits, we specifically go the route, especially here in commercial roofing broken Arrow, we should we specifically go the route of doing mechanically fastened or of fully adhered processes of, of, of roofing installation. So most roofing companies, I would say use a lot of mechanically fastened. The plates and screws are quite costly. Um, but even more so the more expensive version of fastening your roofing system down is that of adhering just basically not labor costs, but basically the glue cost is pretty pricey. So, so those are three different ways that we fashion down commercial roofing systems. And also, let’s say you have a good deck that allows it, we can glue down, we can mechanic, we can fully adhere down the ISO board and then fully adhere, um, any other substrate or fully adhere the upper roofing membrane, the watertight waterproofing membrane.
So that could be done as well. So actually today I’ve got some pretty exciting things. We’re going out to measure a very large modified bitumen roof. I have one of my roof nerves going out with me. We’re going to go out and measure a very large modified bitumen roof. I did some of the perimeter checks yesterday to make sure the roof was looking good in the building, was, was up to code of what we were looking for. And so it’s pretty cool here in commercial roofing broken Arrow, commercial roofing, broken arrow. We’re going to go out of, the crew’s going to go out today and we’re going to do that together, have a little, a little training time. So that’s a large part of what we do in the industry. We want to make sure that our roof nerves are always up to speed on the current systems. And the things that need to be done here in commercial roofing, broken arrow. So we appreciate you joining in another podcast with us today here at advanced commercial systems. Once again, it’s not rocket science, it’s through science and stay dry.
