Here's what I'm gonna talk about today. I wanna tell you a few things, the metal edging around. We're removing the old metal edging. I'm gonna show you how to attach a torch down to metal edging.

I'm gonna show you how to attach the torch down to a fiberglass. See this fiberglass? So I'm gonna do the fiberglass flashing there. That's very unique. You need to see that at the end because that is important.

And then I'm gonna show you also how I install a torch down over this roof, over an existing roof.

And what else I'm gonna show you. I'm gonna show you a few things, the drippage, the flashing, and then I'm gonna show you all the components we use to do this roof. So you're gonna learn a lot. If you watch this roof, it's gonna help you.

Hopefully, I entertain you and I'll teach you and you can help me with thumbs up.

All right, let me show you what I do first. We removing the gravel or the stone. There was a ballast here, and we removing the old drippage. See the drippage?

We're removing the old drippage. All right, so that's what we doing. We preparing this roof to receive a new roof. We got all the stone off. And then blow all the dust off.

And then now we busy putting a base sheet on. The base sheet, now, this is not the base sheet for torch down. This is or a peel and stick cap sheet, but we couldn't find one for torch down, so I'm using this. This is a round booming. We have this round edge, and I have to cut the drippage.

When I do this, I cut this. You can go around the building every 12 inches. See, so that's what I do to get around it. Okay? I have screws, plate and screws, and I put the screw down for this drippage so I make sure this will never come up with a hurricane.

That's it. That is so secure, a hurricane will not bring it up. A roof, I'm gonna explain it to you. People always worry about the wind lift off a roof. A roof cannot lift up unless the wind comes underneath the roof.

And the only way it comes underneath the roof if wind can come in here, come underneath here. But if this is tight against the fascia, wind cannot go in here and lift this up. And then I have the screws with plates, So it's never gonna lift up. That's the principle. You don't want one to be able to come in underneath here and lift this up.

It becomes a sail. This doesn't have to be screwed down, never. It will never lift up. This is tight. It is glued down, but it will never lift up.

But only in the edges where wind can come in, it will lift up and blow the roof off. It's the only place where a roof starts blowing up is if wind can come underneath the membrane, and it will blow up, so that's a principle.

Always make sure your edging is very secure. Now, if you don't have that security, only nailed and it's rusting or whatever, eventually it will come up. That's why most roots blow up.

All right, that was one step, how to do the drippage. We're gonna show you how to tie the drippage in with a membrane, as soon as we get there. The Mule-Hide peel stick base works very good with a torch down, I love it.

So I don't have trouble with it, so that's what I do. Now let me show you about torching.

You don't need to torch a lot. You just wanna burn the plastic. See that plastic? Got the plastic here. (air whooshes against plastic) That's the plastic you wanna burn.

And then you wanna heat up the seam here, okay? That's it. We're in the plastic. You want it to ooze out a little bit. Look, see that?

Just a little bit, not more than a 8th of an inch. If you overheat it, it's not good. Let me show you again. I burn plastic. I heat up the seam, and I roll it with my foot.

And I roll. Let me show you. So when squeeze down with your trill, you want it a little bit to ooze out. See that, nothing more than that. That's perfect.

Again, to torch, we're using a peel and stick base and we just burning the plastic off of the peel and stick, and then I melt the seam.

Let me show you. I burn that plastic. I burn that plastic. I heat up, so this is melted.

You see it's melted there? Look, melted. (air whooshes against plastic) I roll it together and you see it's oozing out on the edge there, okay? I heat up this. I burn the plastic.

I burn the plastic top and I hold my torch while I push with my foot, right there. So I'll do it again. Let me show you. I burn the plastic. So the plastic is burned.

Head up and I hold my torch, then I push with my foot. See that, and it oozes out.

Now this is oozing out more than I would like to, but I'm just doing this for the video. When you want to attach the roofing material, where you wanna attach the roofing material to the drop edge, most people, what they would do is, let me show you what they will do. And this is the wrong thing.

Most people do this. They heat this up. They heat the membrane up all the way, and they push it down off to the middle. That's wrong because the metal will warp and the membrane expands when you're doing that. And over time, the membrane wants to shrink and it shrinks, and then it puts pressure on the drippage, or it pops loose on the drippage.

So you don't want to heat up the membrane and attach it to the metal. It will never work. It doesn't work that way. So what you do is I'll give you my trick. This is a trick I've done for 40 years.

And listen, you gotta read. Read here, right here, sweetheart. People don't read. It says modified bitumen adhesive, adhesive, okay. Read, so what is it?

Adhere to what? That's what you use. All right, it's designed to adhere. So I put the tar, which is compatible to the membrane because there's a modified bitumen membrane, and you wanna put the membrane and the adhesives together, and that will ensure that it sticks to the metal. And I'm gonna explain to you what happens.

So do understand the principle here? What happens is when you heat up the membrane, this membrane, it expands. The metal doesn't expand. So when this expands, when you stick it down, it's in expanded form. Over a year or two, this membrane will shrink, and the tar that is liquid will allow it to shrink, to pull back slightly.

It will give it that little give and slide on that tar and not pull the membrane loose or pull the drippage off of the roof. That's the principle. You don't want to torch it down, but let me show now, just how you do it. I burned myself, I don't have a glove on, you see that? All right, there you go.

Now I made a mess here because my trowel had tar on it. I didn't see that. So the customer might complain because you're using a dirty trowel. Make sure you use the trowel for tar and a trowel for your membrane. You don't wanna use both at the same time.

All right, so there you got it. That's how you attach the membrane, the membrane to the drippage, all right? All right, this is done for the day.

I'll teach you tomorrow how we make a transition to this tepees, all right? So tomorrow we're gonna do a transition here, how we make this membrane adhere to the fiberglass.

So we have to make a transition, all right? That's the next lesson. All right. All right, so the most important part of a roof, and also the last part of what you do on the roof, once you do a roof, is the flashing.

That is the most important part of any roof, flashing.

The metal edging on the edge and the flashing. The roof itself never goes bad, most of the times, but most of the times you have leaks around the flashing. So here, what you normally have to do is, you have to clean the flashing, and I did some of it yesterday, but I'm gonna show you, you clean it with a wire brush like this, okay? Ah, battery's down, thank you. All right.

So it's good to get the battery.

All right, so you get the idea. You clean the surface with a wire brush, and this is happened to be a fiber glass surface. So you cannot just go and torch through a fiberglass surface. And the fiberglass surface, you have to clean it because people paint this.

They use other rubber stuff on it. You cannot go over that. You have to get through the surface. If it's metal, go to the surface of metal. If it's fiberglass, go to the fiberglass, but a unique product that will stick to fiberglass is this a super silicone seal?

That's what I use. Okay. Now I'm gonna show you how I did the torch down. I brought the torch down slightly up, slightly up. You can see it, it's coming about an inch up to the fiberglass.

It makes for a better transition. So if ice and water and whatever sits here, it cannot go up here. But even so, I'm gonna seal it. So it's a double security I'm making. I'm not just using only the super silicone seal.

I'm using two different ways to make this secure, okay? So I'm gonna show you how I do this. What I do is I use a fleece. This is a polyester fleece. I'm gonna cut myself like a four-foot length to get started.

What I need to do is because it's a round object, I'm gonna have to cut like a loose tabs. Amazing, I always have wind when I do this, always. Guaranteed, there's gonna be wind when I do this, guaranteed. I'm gonna put this fleece around there like that. Look how nice it looks.

So it fits right around there, just like that. So like that the super Silicon seal is pliable. Just like that. The super silicon seal is pliable, flexible. It doesn't get it brittle or hard like tar, but it's pliable.

It's flexible. So it will flex whatever the fiberglass does during the summer or winters.

This is the best transition you can have. It will never leak, never come loose. And then you put your fleece right there, right there.

That fleece is a secret to the whole thing. The fleece is what gives the strength. You see how nice it looks? Clean job. It always makes for a perfect job, clean, neat.

And then you take the silicone and you add it to the top. All right, so now I do the same thing again, and this is guaranteed, a simple process if you just knew. And you do the same thing again on top of the fleece, and you'll never have a problem. The fleece is a secret to the whole thing. If you don't have the fleece, it'll work, It will work for a while, but eventually you're gonna have trouble, okay?

You cannot beat that. So that's what it looks like. It's very clear, very nice clean.

Water cannot get in. And it sticks to the membrane.

It sticks to the fiberglass. There is no other way to do it. Other people have EDPM. They put tape on. They did so many things, and it doesn't work.

This will never go back. All right, I'm the Flat Roof Doctor. I know a thing or two, because I've seen a thing or two, blah, blah, blah. Please subscribe, and please thumbs up. But more of all, best of all, thumbs up for this girl.

No! – Thumbs up for this girl. All right, thumbs up for this girl. (woman laughs) We are in Mississippi together doing this roof, and she did most of the work.

All right.

All right. If the camera work is bad, don't thumbs up. Thumbs down for camera work, okay? But if you like the camera work, you thumbs up me. Thank you.

We did this roof in Bartlett, Memphis TN, and we all are the Roofing Contractors. We know a thing or two, because we've seen a thing or two.
