How To Build A Shed – Part 4 Installing Sheet Metal Roof

 

Hi, Shannon here from host improvements.com and we’re back with our fourth video in our five video series on building a shed. In this a video we’re going to cover, uh, putting a sheet metal on the roof. Uh, we aren’t shingling this one, it will be sheet metal. I’ve already got the strapping and metal on the other side. So we’re going to demonstrate what we did there over on this side. Uh, first off it’s a little different than shingling. We want to actually strap the roof, uh, with either one by fours or in our case we’re going to use two by four. Uh, so they’d be running this way. Uh, usually most people recommend about every 30 inches on the roof. Uh, just depends on your snow load and those sorts of things, things you’re building code, that sort of thing. Um, but anyways, I’ve got all that stuff precut so we’re going to start with the strapping and the reason for the strapping, that’s where our rose a screws goal to hold the sheets down.

So that’s why we need them because our sheets are running this way. So obviously we can’t just put a screw on every trust or it, the sheets would be flapping and moving around. So, so we’re going to put the horizontal a roof straps on. So we’ll start with the first one. Like I said, I’ve got them all cut to length and the position, this first one you just want a street edge or anything street so that you can put it against the outside of your facia slide. The strap loop, slide the strap down. I might have to put a nail down there just to hold things still here.

Okay.

Until I get one in. Just give me one second.

Huh?

I will just keep it from sliding off. Okay. So as I was saying, we just want the straight edge put against the facia slide, the strap down to it and then we’ll nail that strap in place.

Okay.

So,

and you would just work your way along the whole length of the roof. I can take this a screw out of here now. So we’re just going to move along. We skipped one, but we’ll go back to it and nail it. I just want to get things held up.

Here we go.

Can you just like that?

okay, so once we have that started on the very outside edges, I have some blocks cut for spacers. So I figured out what I wanted for a the center of my next role and I cut a block two blocks because we, we’re dealing with the shed, we’re going full length, so I’m putting it flush to the outside of the fish on this end. Right. Take down to the strap we already installed

and I’m going to place one in each hand. [inaudible] like that. Yeah,

no, I can take another strap right up on top of there. And we’ve already got our spacing all the way along. So now I just need to flush it up here.

so that’s not one, not done exactly the same thing with the next role. And I’ve gotten premade here.

Okay.

So like I said, a, okay, most places if you’re building something bigger or whatever, and we’re doing this, you can space these straps usually about 30 inches apart.

Right? Like I said, you just have to check with your local building authority.

Okay?

Okay, so we got that on. We’ve got one more strap throw up there.

Okay.

Okay. Okay. So it’s as easy as that for putting the straps on. We’ve got them all nailed. Uh, now we’re going to pop down to the ground and cut our sheets of

metal that are going to go on here. Oh, first, actually I’ve got to put a piece of flashing down here. Then we’ll cut our metal. Uh, in this case, our sheets, uh, we’ve got eat eight foot sheets and we’re cutting them in half to get us four foot pieces. And uh, then, uh, that doesn’t get us right tight at the top of the peak, but once you put the ridge cap on there, it all covers it up and closes everything in. So I’m going to get down.

I’m going to grab a piece of, uh, of uh, he flashing, bring up here and get it tacked in place. Okay? So I’ve got my a eve edge flashing. It’s a much like a drip edge that you would normally use on a roof except a lot larger. In this case we probably could have used a normal drip edge and I just simply cut it with some everyday run of the mill, 10 snips to the right length. And I’m just going to put it on here and we just want this face just pushed up nice and tight to uh, to the facia. And I’m just gonna attack it in place with a few shingle nails. You don’t have to nail the heck out of this because a, when you screw your sheets off, it’s gonna get lots of screws all in it anyways.

Okay.

Couple more and we’ll be good.

Nope.

Are you doing another nail?

Okay.

Okay. So that just helps direct the water down and off of the building. Okay. So I’m going to pop down again. We’re going to, like I said, we’re just cutting some eight foot sheets of a roof metal in half, uh, to get four foot or so. We’ll go down and set up for that and show you what I do there.

Okay.

Okay. So here’s our sheet and uh, we’ve just laid it out on a, on a saw horse. I’m going to measure four feet.

Okay.

Just in a couple spots. We use a straight edge to get myself a street line.

Okay.

Okay. So there’s our cut line. And what I’m going to be cutting this with simply a, a four inch angle grinder with a zippy cutting blade for cutting metal. Uh, I would definitely need safety glasses and hearing protection. So, uh, what I’ll do is, uh, once I get fired up, I’m just going to simply follow that line that I just drew on there and that’ll get her a Sheetz cut in half. Just be wary of what’s around you. Uh, there will be sparks. You could cut this outside if it’s better. Um, or just watch, I mean, you don’t want anything flammable behind you or around you where a sparks could cause a problem.

Okay. okay. So that gets our length cut. Like, so, and we’re going to be starting from this. And do you want to, uh, pay a bit of attention? Uh, as far as the wind direction or the direction the wind would generally come from in your area? Um, so that when you lap the sheets, they’re not facing in the direction that the wind would come from. You know, because they, they do overlap. You don’t, one edge overlaps the next edge and uh, you just want the prevailing winds not to be able to get ahold of it. So this one, uh, we’re gonna put back there or up on that end, we’re gonna orientate it just like this be the top. This would be the bottom of the sheet. I’ve predetermined my screw locations, so I’m going to pre mark those all out on the sheets so that my screws look good up on the roof. Nobody really sees it, but it’s just good practice. And if you’re doing a wall or something, you definitely want to try to mark them out so that they’re consistent when, when a person looks down the wall. So, uh, in, in my case, these first ones are gonna end up at two inches. And on the bottom edge of the sheet, I’m going to put a screw in each one of these locations that I’m marking.

I’m just putting a little tick there.

It’s easy enough by eye to center it up. There’s a actually a little bit of a rib space there. So by eye you can center that part up. Uh, my next row ends up being 26 inches. Now once you get away from that leading edge, these ones, you really only need that screw on in this position. That’s towards the, the edge of the sheet that’s gonna overlap the last one you lead. So 26,

okay,

free marking this out cause it’s much easier to do down here on the ground. And you would just keep going like that depending on the length of your sheet. Our upper row is actually gonna be a secured with the ridge cap, so I don’t need to really mark those out. There’ll be, there’ll be hidden away. Okay. So we’ve got that. And now the other thing,

okay.

Uh, actually that would be on the next sheet on the next sheet. Cause when I laid us on the roof this will be the next sheet.

It’s going to overlap that rib. We’re flush up the bottom. So we’d have a row of screws down here again at two inches in my case in other row at 26. But then we’d also put in a stitcher, which ends up on this high rib on the one that overlaps the other and it’d just be spaced in between the two, the two screws you have here. So we’ll put a screw here in the high rib, one in between, one lining up with our role and other one in the middle there. So maybe I’ll mark with sheet oat as well while I’m down here to let me sit. Okay.

Oops, I didn’t mean to mark that one. You don’t need one there. Okay. So those are our two full sheets. It ends up being a partial sheet our last row. So again, I’ll have to cut it. I’m going to throw some screws in my pocket.

So these screws are uh, they come color matched for whatever color your sheet is. There’s different lengths, different, uh, screw types depending on what you’re going into. These ones are actually a little long for this application, but it’s going to be all right. Um, when you put the screw in, you’ve got a, a hex type head that, uh, we have a driver in the drill that fits that. There’s a metal washer and then there’s a rubber gasket. So when you put these screws in, you want to just make sure you’re not just squeezing living life out of, out of that rubber gasket. You wanted to come down and make contact and just, uh, just be solid, not over tightened. We also will have these foam closures. We need them along the bottom because otherwise birds and flies, whatever can fly up through the high rib area here. So this gasket actually fits underneath and when we screw, we just push it up to where our screws, we’ll go right through it and hold it in place. So it just fills in that that void that’s underneath there and makes a bit of a weather proof seal. So we’re going to need those up there. I’ve got my drill. So I’ll take this first sheet up.

Okay.

And we’ll get it laying up on here. So now, so we want to start out with this edge of this sheet not sticking over the end. If anything it can be a little bit short of the edge, wouldn’t matter. I’ve got a block here just marked with a mark for how much I want to overhang. That’s a little bit up to you. I’d like to have about about an inch of overhang.

Yeah.

So I just kind of get things lined up here. So we’re really quite close there, just like that. So I’m going to put the first screw. Oh, I didn’t put my, that all lined up and I don’t have my closure under there. Okay. So we’re just going to lay the closure there. Some of them have a sticky back that you can peel off and then it’ll stick in place. This particular one doesn’t happen. These ones that don’t seem to have it. So we’ll get our sheet sitting down on there and we’ll get lined up again.

Okay,

great. Like, so we’ll get one screw in this corner. So things go on.

Okay, so we got that one in. I’m just getting this sidelined up.

Wow.

Another screw. Just making sure that closure’s up there high enough.

yeah.

Okay. So one thing you have to be careful of when you’re screwing off these sheets is you can actually stretch them or shrink them in width because this’ll flex when you’re putting in the screws. So if you’re putting your screws in on angles, it’s kind of distorting the sheet, uh, from how it should be. So you have to just be a little bit weary of that. That can help you at times. Sometimes you get off a little bit and you need to stretch a sheet or string shrink a sheet. So you know, just be, be aware that you can do it if you need it, but you’re, you’re trying to avoid that. Of course. Uh, so that all looks pretty good. So I’m just going to put a couple more screws in just to hold it and we’ll move on to the next sheet. I can screw it off later.

you want to be careful. All these edges are sharp. Uh, some people will wear gloves all the time.

okay, I’m just going to step up and get a couple of screws higher up.

so like I said, we put all those pencil marks there and I will go back and put those screws in. But just for time savings here, I’m just going to move along to the next sheet. Uh, these phone closures kind of have an interlocking piece at the end, so, uh, you just have to orientate them the same so that they can get it in there, probably have to loosen the screw.

so I can pull this up. I hoped in there, put that back down and I’ll just hop down and grab my feet. And basically we just keep going.

so you can see we’ve got the overlap there. Sat over that. I’m bringing it down flush to the sheet that we already put on. We’ll put this first screw in the corner.

Okay. good.

So grab my little space. Your block should be able to come down. I just want to make sure that your ribs sitting right. Just like that. And then I can put this one in again. I want to be sure that foam closure is up and it’s actually slid and how in a bit, I’m going to try to be screened through it so it keeps it in place.

okay, so you’ve just simply continue along just like that. Uh, like I said, our next one is actually a cut sheet. So I will have one at four feet, but it’ll be sliced narrower than, than the three feet. These ones are. So I’m going to get those finished, getting this all on. And then when we come back, I’m going to show you how to do the rest of the trim. There’s a gable you’ve trim here and then the a ridge tower. Okay. So I’m back and we’ve got all the sheets on the side, all, uh, cut and secured. So that’s all done. We’ve actually put the gable flashing the backside and we’re going to do the gable flashing now on the front side. So that’s what this piece of 10 here is. And I’m just going to lay it on here. We have to do some cutting.

You’re gonna make it work.

So I’m just, uh, pushing it tight against the face here and tight down and I’m sliding it down til, uh, the two corners kind of match up a little bit. And I want to get a mark here. So we’re going to cut out this corner right there and we’re going to cut a line up here and then I’m going to fold this underneath just so it closes that off. Some people will do that, some people won’t. I don’t know. I just like to do it to keep bugs and stuff out of there again. So, uh,

another mark here. So I’m going to cut that and that other corner. Okay.

Okay. So again, I’m just using the tin snips.

Okay.

Should I really get around on the side?

Okay.

So I cut that little piece out of there and I’m going to cut this lip off.

Okay.

And then this piece here is actually going to fold full down here. Again, watch this stuff is very sharp so that’s just going to kind of close off that and you’ll see it better. We’ll try to get up

picture of it after, but I can set it back on here. Double check that everything is sitting the way I want it. That looks all right. And I’m going to get a screw in there. Hold it up there for me. Yeah,

so I’m just going to line line these screws up with the ones we had in our other rows there and they’re going to go down on this, this flat area over on the other side that sits down on the roof.

hold it down for moving them around on me. The one here. Okay.

okay, so that’ll just keep it from moving on me. Now we’re going to go up here. We need to make a couple cuts here in the center as well. So I need to fall this, this a joint in the facial boards. I’m just going to kind of eyeball that up. Get my angle. I think a pencil line there to follow and we’re not going to mark a line rate across, but I’m going to come just to the back corner here. So I need to make a cut there as well so that basically this piece will fold down. So I’ll make this one first.

Okay.

That one doesn’t have to be pretty because it doesn’t get seen. Again, you could do this in two pieces too. It wouldn’t really wouldn’t make any difference. The Ridge cap itself, we’ll cover this when it’s done and uh, and I’m going to cut straight up there just to this corner.

Okay.

It’s kind of awkward. I want to kind of do it this way, but I know you’re not going to see boats. I got to do it this way and then I’ll show you. This is really awkward by myself.

okay, there we go. Okay, so then this will just fold like that. The other side goes down and uh, I need one more little cup here.

Okay.

And that’ll just allow that to all sit flat once it, once it’s done. So we’ve got this back piece bent, folded and it just allows this to come down so we can get over on this side and basically fit it and cut it like we did on the other end there where we started.

So I need this. I’m really just doing the same thing at this end. I’m sure I’m going to have people come on and comment that that’s not how they do it. But anyways, that’s how I do it. Okay, so we’ve got that all fit. We’ve got that side. Good. We’re going to put our screws in down this edge to hold that down once we have our other aluminum facia on and tucked underneath there. We’ll be putting a couple screws in all of this just to hold that all tight, but we aren’t at that stage yet.

okay, so we’ve got that on there and put another one up near the top here. I want to be near the top, but I want to still be below that where the ridge

captain to come to.

Okay, so there’s your gable and flashing another step down. So really all we have left to do now is the actual ridge cap. So I’m going to cut it to length and it’s going to go really just raid end to end up, probably going to cut it back just a quarter inch short so it doesn’t hang over at all. Um, so I cut it to length and then I’ve got, so I’ve got to cut it. So this, that uh, or sorry. No, I guess it is going to sit right on here. And we do have a foam closure that goes in here as well. It’s kind of the opposite of what we use down there. Now it’ll be thicker in the, in the main part here and thinner where it goes over top of the, uh, the ribs. Uh, the other thing, uh, we have to be real careful now at this point too because we do have to get right up there. This is slippery obviously and it can be a little bit dangerous. So you gotta be careful getting up there and find a good spot to perch and not fall off of. Okay, so we’re a backup top here. We’re gonna put the ridge cap on, we’ve put on the foam closures. These ones were sticky so they stick in place. Uh, we’ve cut the, the ridge cap length. I’m just gonna bring it over and this is going to get screwed down into every, every high rib there.

So I’m just going to get one in here. I’m just centering it up on this part, pushing it down tight.

just like that.

Actually I pulled a little bit off center there, but woo again, slippery up here.

so we’ll just do the same thing over here. Got Ourselves kind of lined up in street and we’re just making sure that’s tucked in over there. I’m just going to put a few screws in here.

I’ll come back and screw it off after we’re done. So we’ll get this in over here, right?

And you can kind of push that forum foam closure, even if it is sticking out, it’s not really usually that big of a deal.

Yeah.

Just like, so anyways, I’d go right along like that and finish screen that off. Like I said, a screw on every high rib one out on these corners and that would finish it up. Okay. So there a, there you have it. We’ve uh, put the steel sheeting on the roof and all the trim on for the roof and uh, I think it gave you a bit of a basic id on how to do that. Obviously it’s going to change a little bit on the bigger if you do a bigger building, but the same principles are all the same. Uh, so I think that’s good. We’re going to wrap things up and uh, you can always come and check our forum out on the website. If you have any questions about this or any other project you’re doing or you’ve seen us do, just go on the forum and ask about it. Uh, then, uh, yeah, keep watching for the fifth video and we’ll get things wrapped up on this project.
