How to measure and cut the metal on a valley for metal roof.

⏱️⏱️Chapters⏱️⏱️
00:00 One of the tricky parts of doing a valley
00:48 Want to find the angle
01:06 Take a squared off piece, generally 36″
01:37 Keep it square with the piece you’re measuring from
01:48 Other side even with the line you popped
02:05 Measure where you will lap, not the edge
02:30 When you get your angle, that will tell you where to pop a line to keep square
02:50 Measure up the roof
03:22 Cutting once you have your measurements
04:20 Here’s where your angle comes in, go 38 1/4 up
05:10 How to cut if you work by yourself
06:10 Pop your line to cut the metal roofing
06:35 Types of snipes you can use
07:05 Trick for cutting metal roofing
08:35 Trick when placing your metal-run it along the rib
09:20 Want to screw into your 2 ft centers, keeps metal on even during high winds
10:00 Stay 2-3″ up because will put in valley foam
10:25 Now you know the valley angle, you should be able to pop your lines
10:35 Check at first then you know your angles
11:00 Metal roof valley going down need to determine the angle

Doing a valley is getting the angles righthand I’ll show you how I do it. And of course, there’s other ways to do it. This is what I’m seeing some of them ever since before. And I’ve helped a lot already got started.

But it’s basically what I do is I take you’re going to be any color and this works. I wait for traffic and airplane traffic here. So what I’m trying to do is find the angle for this. So what I’m going to do is take a squared off, piece generally wanted to be around 36 inches or, or more than the mark it might notice that I’m kind of cautious on this roof because it’s best Be careful if you’re going to get on my recommendation to get on it.when it’s wet Alright, not that great.

So they don’t have this. So as straight as possible, then you want this point right here, which is not the lip, but actually decided the rib. To me, even with that line, if you popped. Get that you can take a pencil and mark it quite often I just take a tape measure and the classic mistake, which I’ve done bunches of times, as you measure on this,side I was thinking oh yeah, this is what I gotta do. But you don’t, because it laps over, it’s got to go down to the bottom of the other side.

So that won’t change the angle. This is 38 and a quarter angle. So I know that whatever the length of this is, I need whenever it’s square to cross I need to go 38 and a quarter up on this side and then pop a line or mark a line with a straight edge a then cut across, which I’ll show you that.

So what we’re doing next is getting this out of the way so I don’t fall off the roof. Measuring up the roof 243 All right, we’ll take it to the next level, we start measuring up that one angle, we’re gonna go down 243 although you can mark right here, if you can find it down on the side and 243.

So what I’m gonna do is measure from this end 39 three quarters and do the same over here. That way we have this point that was the same to me. We could pop a line across. We’re gonna do. We didn’t know that it’s 38 and a quarter up on that angle because we took that squared piece, which would be the same as going up there and 38 and a quarter, but we’re gonna go over here. In that point that we measured from here, you could do 243 over there.

Same thing, just a little shorter. We pulled that way. Then I go 38 and a quarter up on that. Shadow made a mark here. And it’s got to go to that 243 mark over there. So what I normally do when I work by myself, God bless your soul if you do work by yourself. Gotcha.

And I take my chalk line got to work in chuckling I thought I did. Remember it’s not to that marks to the one on the side. And they kind of hold a little bit on the loose, so it will pop down it. There’s the angle. These are us straights yellow handles but you can use green or red.

They just have stronger strength to turn left with green. I think it’s strong strength to turn right with red where straights a stronger going straight, but we can go left or right just they’re not as good.

Now one of the tricks that i was showing people earlier is I lift up on one side hold down the other side kind of encourage it to tear and then I use the snips to tell him where to tear turns a little bit sideways so I don’t have to interfere with where the metal folds up. Either cutting your hand or just getting in the way of working. There we go.

That’s how that part is done. I’ll show you some more as we go along. What I been doing is putting it on the rib taking care not to scratch existing metal and trying to sliding as close as I can.to the edge Already got some screws on to two-foot centers.

I’ve seen it wider but I’ve never had a roof off center. I had a tornado warning. That’s it. The match tree damage. Trees either make a dent or sometimes in the country from the impact to foot center. I’ve never had a problem, so I’m not going to fix it. They want to stay in.

Now, whenever you’re screwing this off, you don’t want to get real close to the edge like stay about two or three inches up. Reason is we’re going to put in Valley foam afterwards. And I’ll show you how that’s done later, but you just do the same thing. You don’t have to measure every time now you know what that angle is, unless somehow changes back and forth.

We should have a straight valley where you pop the land on the sides and put it straight. So that angle B 38 and a quarter all the way up on this one.

We will check every one of them whenever I first started out, so I encourage you to be careful. But you can do it yourself. Just be careful. You got your friends. Again, watch the wind. You can take both of you off the roof. It gets to be too windy, just stop but it live another day.

Like better to be a live dog than a dead lion alright guys we did valley where you’re coming up.

This is going down and getting enabled. So what we had to do was determine that angle also. point this is gonna keep it straight to our line down below. And it’s showing. So that would be how you would get your angle. on the long side you have to cut it down
