A leak, common leaks on a flat roof is a chimney. And especially on residential roofs. So I'm gonna show you how to look for the leak. And then I'm gonna show you how to repair the leak very, very, very simple, very easy. But it's to find that most people would not know where to look for it. Now, in this case, let me show you, the roof is leaking at the corner of the skylight. And above them, in the house, the roof is leaking right here. And it looks like it appears that the skylight is leaking. But the roof is slanted, so it's not the skylight that's leaking, but something that's leaking above the skylight. So what's the next thing above the skylight? The roof cannot leak. This is slanted, the membrane is good. The next thing above the skylight is a chimney. So look at this line, and you can understand what I'm talking about. The line of the chimney towards the corner of that skylight. Oh, okay, so now what's leaking? You could be flashing on a, on a siding, but it's not. I know this is not leaking, the flashing. So here's the common issue. If the flashing is done right, in this case it is, this membrane is attached to the flashing, then what else could be leaking? Then you have to look at this. You look at the whole chimney. Let me first show you the chimney. There's almost, there's a good chimney, except there's some cracks there. I don't know if you can see it, I cannot reach, but there's cracks there. And that should be taken care of. There's cracks there, you see there. Some cracks there, you see there. All of this could cause the chimney to leak at the bottom here. And, but I'm gonna show you what causes, so, when water runs down this chimney, what happens is, somebody called this, and this is okay, but the clock never lasts. So let me show you. So this opens up. This is completely open. I wanna show you. That, that's completely open there, but I wanna show you. I cannot take it apart. But this is where water comes in, right there. This is attached to the metal, but the caulking comes loose from that cement or from the brake. And it actually diverts the water behind this. So that's the issue. So what are we gonna do is, I'm gonna show you how quickly to fix this. So you never have to caulker again or, caulking is not the right way. I don't believe in caulking, so I'm gonna show you how to do this. I wanna hold this up. So, what I do is, I use this product, books, turbo polysue, you see it? And it's from booksroom.com, you can see booksroom.com there. Now, this is an excellent, excellent product. And you just paint it on and, water, it's done. Now, to make it look nice, because sometimes you wanna look professional, I use some tape, if I can get it loose. And, oh, my goodness. Okay, so to look a little bit more professional, I will tape off the section so I don't get this paint, this stuff on everything. So what I'm gonna do is, I'm gonna paint this like this, like that, a little bit more. Okay. I put it on this side, just to make it look nice. Something like that, okay. So now, so what you do is, you paint this product on. Okay, I'm gonna paint this on here. Now, you can see why I wanted to put the tape there, because I wanted to look like a mess. Okay, so I do it all the way around. Okay, so I got that painted on. I take this off. Try this right from the corner there. Okay, like that. Just like that, right today. I just wanna do this first. Okay. Right today, I apply that. So that's it. Now, that's just how quickly and easily, now, caulking would be faster, but caulking doesn't last. And then you have to, you know, and it's messy. So let me show you. Okay. That's it. Okay. So we got it applied. Once you got everything painted, covered. Ah, and then, and you got all the tape off. That's it. And, excuse me. Ah. That's it. Very, very nice and clean. So, that's how easily I fix chimney flashing. Anytime you have a leak, check that the caulking that come loose and you fix it. I'm the flat roof doctor. I know a thing or two, because I've seen a thing or two. By the way, we did the flashing on this. Skylight. Look at it. A while ago, the whole skylight. And it's very, very nicely done. It will never, never leak. Same thing. Same idea. Time to do a repair. I love this. Watch this. Whoa. Whoa. That's unbelievable. Whoa.
