Today is another great day here with advanced commercial systems. Hold the roof nerds. Today we’re having another podcast week after week. We’re having podcast here concerning commercial roofing and here at advanced commercial systems because we are the home of the roof nerds. We love to talk about commercial roofing. It is what, uh, we, we wake up in the morning thinking about, we think about it all day. We think about it at night. We’re continually studying that we are continually endeavoring to be the best. We can do B here in commercial roofing broken arrow. So as far as advanced commercial system is concerned, we are thoroughly pleased, uh, and do enjoy the, how much the community has continually begin to, you know, communicate with us concerning other many podcasts that we’ve done. And then also just the mini podcasts that we’re doing. We’re getting a lot of feedback during the podcast as well.
So, you know, the last few podcasts we’ve been talking about are 30 point checklist that we have here when we show up to do an inspection to do an evaluation. Because that’s, that’s really what I like to call, what we do for our clients is an evaluation. So when we show up to do an evaluation of a commercial roof, whether a steep slope, low slope, uh, doesn’t matter, uh, we do a 30 point checklist and today we’re going to continue as we have been here in commercial roofing broken Arrow to continue to go through some of these, some of these checklists and some of the things that we look for and with every inspection, every evaluation and that we also report back to our potential clients and our clients to really let them know between pictures and video and, uh, data, uh, accumulation and, uh, you know, documentation of what we’re doing.
Uh, we really make their Iq, their roofing Iq smarter. So with that being the case, so let’s start off today with just a list of some of the things that we do, a cover and a with that. Amen. Imagine you can, you could pretty easily imagined that we, we do inspect for hail damage and we are professionals and certified with an engineering company for looking for hell damage and wind damage. So Helen wind damage where the two of the top things we always look for because those are the two things that allow someone else to pay for your roof. If you have an insurance policy on your building, there’s a great chance with the hail or wind damage being found that whether you have a repair or replacement that can be taking care of by their insurance company. So there’s nothing better than getting your roof taken care of by someone else’s pocket book.
And so those are two things that we look for. Another thing is foot to traffic damage. Now foot traffic damages where there’s, you see that a lot really on flat roofs and steep slope roofs, especially steep slope roofs. Normally when they’re installed during the summertime it gets really hot. The guys are hanging out on the roof in a certain area for awhile. You can see, you can see some gouges in the shingles and you can also see a considerable amount of lost granulation in certain areas just because of foot traffic. Now with flat roofs, I see a lot, we’ve done some coatings over the last year that we’ve gone back and then h Vac unit has been replaced. I’m right next to it, you know where our coding was around a unit and we’ve seen that our coding would have tears, would have issues because of foot traffic of the HVHC guys, you know, they don’t care about the roof.
They, they just really, I’m shocked at the damage I continually see those guys doing and I appreciate them. I appreciate what they do, appreciate what they do, you know, in the industry of construction. But I wish they would do a little better or quite a bit better at taking care of the roofs that were trying to take care of. So I’m, so foot traffic is a big part of what we see. That’s why for one reason, like with TPO and PVC and especially even that with EPM which isn’t quite as durable, we’ve seen more and more foot traffic areas where we put in what’s called walkways. Now a walkway is a three foot wide strips, sometimes two and a half foot wide strip. They’re pretty expensive, but we we’ll weld them down to the TPO or PVC. We will glue those down to the PDM.
The EPD m that we’re currently working on at the maximum building complex here in Tulsa has quite a bit of um, you know, round the SBAC units has quite a bit of a double layer of ETP DPM. PDM that actually works as a protector is a two foot traffic, high foot traffic protecting area. And so with that being the case, let’s move on to our next one that we have. Let’s see, we have, uh, basically just inspecting the membrane. Now the, when I say membrane, when I’m literally referring to is the actual upper surface of the roof. That is what we call the roof membrane is the upper layer that actually is affected by water that has water and rain and dust and bird droppings and foot traffic and especially UV rays from the sun. We inspect that top membrane layer to see how it’s been doing, how it’s handling, you know, does it having cracking, is it having blistering?
Is it having, you know, any lap problems, any wrinkles. We inspect that membrane and really try to see, we’ll try to accumulate the information of how old is the membrane and how much more life would that have because that is the waterproofing layer for the entire roofing system. And so one of the next things we looked at is damaged areas around equipment, um, mechanical equipment and accessories like that. So as I just shared one of those just a few minutes minutes ago about some coding that we’d done that was getting damaged. So around h Vac, oh, I mean, just what was it one week ago? Um, I found a pretty good size puncture hole right next to an HVC unit where it had been installed in commercial roofing, broken arrow. And here in commercial roofing broken arrow. That’s something that we see and we have to patch that and immediately because it’s just a allowing a continual flow of water into the building.
So always looking out for, you know, the equipment and equipment supports. Now equipment supports law many times that is basically wood, four by fours that h vac units, you know, you’ve got a 300, 400 pound unit sitting on Hvas. I sitting on four by four words and many times they’ll put the four by four right on top of the roof. Uh, with the weight with over time I’ve see where they just sync three inches into mod bit, causing potential leaking, causing problems. And now one of the issues is these four by fours, they might not be pressure treated, they might not be, um, weather sensitive treated. And so with that, after a few years, they begin to rotten out and they began to splinter and they begin to cause even more problems than just, you know, the weight exposure of how they’re digging into the membrane. So that’s something that we definitely look for and we see a lot with another.
Is that of degradation caused by ponding now degradation of just like you would think it would be is a sunken in areas. So here in uh, you know, Tulsa, uh, we see a lot of roofs, especially here in commercial roofing, broken Arrow, we say lot of roofs that have big ration and that’s very common with almost every roofing system that we don’t see that very often. Very seldom do we see little metal roofs. Uh, we look at a lot of our panel metal roofs and actually just was on, I know schools a few days ago and they have um, a few weeks ago and they haven’t a standing seam interlock standing seam system there. Um, but you see very little because of the, as you normally have a decent slope with your metal roofs and because of that you see very, very little, um, you know, degradation degradation, uh, which would cause ponding areas.
So basically what you’re talking about is like on a lot of my bit roofs we see and built up roofs. You have a sunken area so it’s a little bit of a ponding area and the water begins upon and after a few years of the weight of that water drying and accumulating drought and the community, it literally causes the ponding area to sync and get deeper. So you can start with a one, one and a half inch ponding area and within a few years it could be three inches deep, three and a half inches deep. And so it just begins to put boot the way down that area of the roof. I a lot of times what is happening from that, it is causing a, uh, a concentrated degradation of the ISO board because it is able to be crushed over time. And so that’s a large part of what we see here in commercial roofing, broken Arrow as well.
And so holes punctures in the membrane. Now that’s part of our membrane membrane inspection. We were talking about while ago and we did talk about holes and punctures, but sometimes you just have holes because it wasn’t, it wasn’t welded well. Um, and then another would be worn out or deteriorated membrane. Uh, not specifically. You know, a lot of people ask about, you know, how long does TPO last, you know, thermoplastics how long do they last? How well do they do now you have different kinds. We’ve, we installed a 45 mil. Oh, a few years ago we installed a lot of 60 mil. Um, there’s some, there’s some 80 male, there’s some 90 mail. You go fleece back, you go all the way up to 130 meal. And so is it, is it comes down to it. Um, the worn out deteriorated membranes we’ve seen had been a lot of Pv as a lot of TPOs and uh, actually a Dura last through this recently on a whole church that we were inspecting.
And it just gets really chalky. And the whole upper layer above the scrim, the top coat of that TPOs a membrane is just completely worn down and you’re beginning to see the fibers of the scram. So, um, so these are today we’re just some of the things that we see here in commercial roofing, broken Arrow, a lot of roofing companies, a lot of roofing contractors. Um, they have tons of questions for us as well of just, I mean, just yesterday we were having a roofing contractor and the roofing companies give me a call and we asked her some questions about roofing and about some specifics, you know, cause we do operate as a commercial roofing company and we do operate as a general contractor that we do different other kinds of jobs as well. So, but our focus and our passion definitely is that here in commercial roofing, broken Arrow definitely is that of commercial roofing.
So Hey, we thank you guys for joining in with us today for another podcast. Uh, we appreciate your time. Once again, we were carrying a w talking about quite a bit of the different types of the 30 uh, 30 punch list that we go through, the 30 point checklist that we go through every time we do a roof evaluation for a commercial roof, better than other roofing contractors, better than other roofing companies. Hands down the best system that, that we can bring to the table here. We appreciate you for joining in. We will see you next week for our next podcast and today was our 114th podcasts, so we appreciate you guys joining in for so many weeks with us. Uh, stay dry.
