Another way to line up the steel sheets is to tack a temporary strip to the ends of the rafters to match the desired overhang, and tack a protruding strip to the strip making a little shelf that you can rest the steel against. Very fast and accurate especially if you are alone you don't have the sheet sliding up and down, just toss it against the shelf strip and it's instantly perfect.

I used to do something similar, especially since it makes it easier when working alone, but I found that the rafter tails are never perfectly inline, so it can introduce problems and make the panels wander. That's what got me using the string. Since it's only attached to the end rafters, it's a perfectly straight reference line and leaves a nice straight roof edge. I can look up under the edge and see that the rafters and purlins have some wander in and out, but the metal roof is dead straight.

That's an awesome tip!!! I've never built anything before with a metal roof, currently roofing my 30x56 shop. My buddy is a carpenter and referrs to me as "the wood butcher", came over and looked at the side I had done. He asked me who I hired to do it, I said " I did it" he still don't believe me. Keep up the good work, you are single handedly making dummies like me into semi-capable home owners.

As a Metal Roofing Contracto in NE Ohio, this is my go to method of “truing” up the eave. Along with the string line method I also double check by squaring the first panel with the Pythagorean theorem( 3,4,5,method) . Using that line I make multiple vertical reference lines onto the roof , checking panels as I go. If installing exposed fastener metal roof panel I always stack the required amount of panels per roof section, clamp together, mark all fastener locations, then drill all holes with 1/8 bit. This method ensures a professional and ascetically looking fastening pattern..be careful not to overdrive fasteners. Optional, If using butyl tape / sealant on the top underlying rib of the overlap panel , be careful not to block what is called the anti siphon rib. Fastening the overlap rib is usually done when there is gaps in the overlap caused by uneven decking / purlins. Good Luck with your Metal Roof

sir, is it better to drill the screw at the low or high spot of the metal roof? drilling at the high spot would seem to be the better location to avoid leaks as less water would be running down it.

If you mean the "clutch", unfortunately it is not consistent enough for metal roofing going into wood, due to variations in the wood grain and structure from screw to screw. There is no single setting that is right for every screw. There are specialized drivers for roofing screws that limit depth, but they are very expensive. My preference is an impact driver since you get very fine control as the screw tightens down and can stop when the gasket is perfect without overdriving the screw.

Until a few years down the road when shrinking wood and wind have worked some space under and around a few screws and let water in. Screwing through the ridges into properly sized and shaped wood stringers all but eliminates future leaks. Lumber Jack builds with more strength and precision than most, so he'll probably get away with screwing roof panels through the valleys.

Leaving consistent daylight to your string is essential. If you touch the string you’ll bend the line. Commonly when using a string to line stuff up you run the string over blocks at both ends and use a block of the same as a feeler gauge

I enjoyed your information and It gave me affirmation to what I was already doing. However, here in the great white north we put the screws on top of the ridges. This is due to ice damming and the gradual snow melt that can leak through any lower installed screws. I also pre screw all panels , use 3,4,5, squaring and the sting line. I also use temporary wood eaves stops so the panel won't slide down wile installing especially on 10/12 and steeper. Good job Jack

Apart from the ridge cap, never put screws on the ridges. Talk to any metal supplier and they will tell you to always screw on the flat. I guarantee you will have leaks on the ridges of some of the overlaps because it is really hard to screw perfectly vertical on the rib and easy to get off at a slight angle on the covered rib causing a hole where the water will run through even if you can't see it and it is on the strapping. There are other issues too including undertightening and overtightening and warping the sheets so they no longer lay flat. Forget about what the old timers may have done. That was then and this is now. Oh, I should add that I'm 75 and have decades of experience, and Yes, I did start out 50 years ago screwing on the ribs.

The Metal Sheets are adjustable like an "Accordion" a music instrument. All's you do is put a couple screws one in the overlap and right hand bottom corner. If your Eve is straight, have the over-hang marked on the sheet then screw them down. No need for a string line. I mean you don't see Roofer's putting a string line down when they put on shingles. Shove or pull the overlap on to the prior sheet in place and screw down, then you can push the top right hand corner or pull it up from the center which will cause an upwards bow in the middle, screw that down to the width you want. Mark that on the board below you can move it up to a half inch easily per sheet. It will lay down perfectly flat the ribs can narrow slightly and you will not notice and they can be stretched slightly and you will not notice. Making up any difference to being square with you Gable end. Three generations of building and Roofing. Age 65.

I have never done metal roof. Mostly because I’ve done so many shingle roofs and it’s easy, I don’t have to think or learn something new. Also, all the structures on my property have the same shingles and it looks consistent. But my next project will be a tiny house on a flatbed trailer base, so reducing weight is a priority. This video made me feel more comfortable about metal roofing. One question, how do you walk on it? Stepping exactly over the 2x4s? What about slipping?
@Lumber_Jack
@Lumber_Jack 3 жыл бұрын
To walk on a metal roof over purlins, you really need 26ga PBR (purlin-bearing-rib) panels for support. I used those on my boathouse roof and they are very stiff and supportive. For this carport, I used 29ga imperial rib which you can't walk on, or it would dent. I never walked directly on the panels, always worked while perched adjacent to them on the framing. To put on the ridge cap, I laid a ladder flat on the roof with carpet scraps to prevent scratching. The ladder distributes weight and also lets you get to the ridge without slipping. If you do metal over OSB, then you don't need to worry about denting the roof. But with the high cost of OSB nowadays, that gets expensive (you also need vapor barrier too). Any pitch over 4:12 is too slippery to walk on in my experience (even 4:12 gets dicey). Need to lay a ladder on the roof to climb up.

I’m ready to install my panels, I’m so glad I watched this video. The only problem I have now is my metal roof supplier said that since I used yellow treated wood from HD on my 1x4s that my roof warranty was void. Now I find out, what do you all think? Will dry yellow wood rust out my panels? I’m not replacing them, I guess I could paint them but I really didn’t want to hassle with it.
@Lumber_Jack
@Lumber_Jack 2 жыл бұрын
It definitely is a concern -- the treated wood can cause major corrosion of the metal panels where the screws poke through and any other places with direct contact. However, I have put metal roofing down onto treated lumber many times for marine structures. I put down self-adhesive flashing membrane on top of the roof purlins, to isolate the metal panels from contact with the wood. In addition, pre-drilling screw holes in the panels helps minimize issues at screw holes. Finally, you must use hot-dipped galvanized roofing screws, not the standard plated roofing screws (they will rust out and crumble within a couple years when used in treated lumber). Hot dipped screws are a little harder to find in all lengths, but usually available if you search around. In lieu of all these adjustments, it may be simpler to replace your treated purlins with standard lumber. Purlins tend to be out of the weather and you can often get by with standard lumber for them even when treated lumber is required for the rest of the structure.

Haven't done this yet but my plan has been to string at the top. Theoretically that should act the same since the panels are all the same length. I'm rethinking that now but we'll see; my drip edge is about 20' AGL. It seems like it would be easier to watch the peak string than the bottom string since we're at 4/12 and we sheathed the roof. Predrilling is smart but our purlins are on edge and a little wavy so I'm a little leery about doing that for our installation. Looks like we have the same or close to the same tractor and fork clamps.

So LJ, to follow up, we got the west side done about three weeks ago. I ran a string across the peak and it helped but we didn't do such a perfect job of keeping the drip edge and fascia straight so the panel bottoms creep a little. It's not distracting from way down at ground level but it could be better. After that side of the roof we moved on to side panels. We finished the west and north (gable) walls and are about halfway through the east wall. I pre -drilled the wall panels (target window 5.5") and that helped a lot. It was "fun" cutting those 24' panels to fit the gable slope but we got it! Overall we're very pleased with how it's coming out and think it looks good. We have two panels on the east roof slope (it takes 21 and they're 23' long) which we just "eyeballed". (It was too windy one day to work on the side). I'll use Mr Graham's idea of marking the panels and lining up with a line on the roof to see if we can improve alignment to our fascia variation. I'm stoked now that I have a new approach idea!

Fascia (or any part of the framing/trim) will rarely be as straight as a string stretched tight between two points, which is guaranteed to be perfectly straight. Minor variations in the framing/trim can let errors stack up and create hassles and cause a sawtooth edge on the metal roof. So the whole point of the string is to establish a perfectly straight independent reference that doesn't depend on the framing/trim along the eave line.

That is if you're last,in your case 1x4 is straight along the eve, you just follow the corner of it from one end of the building to the other and as far as the Gable-end, having it come up too wide or too narrow at the top of the sheet/s will accordion, so you can push them closer together "the ribs" or they can be stretched and come out exactly where you want it.

The whole point of the string line is that the framing is never perfectly straight. If you set the overhang based on the bottom eave purlin (which is a 2x4 here), then the edge of your roof will likely not be straight. The string, on the other hand, is stretched tight between two points and is 100% straight. Following that gives a consistently straight roof on every project, no matter what the framing and purlins are doing. This is especially helpful on pole barns and timber frame structures where building tolerances tend to be a bit loose.

@Lumber_Jack

Boy, that is a tough job if the metal is already up. Many people use a skil saw (circular saw) with the blade turned backwards. It will make a nice cut but the edges of the metal will eventually rust and the heat can damage the finish if it's painted panel. I am sure there are videos showing it being done, so take a look and see if you like that approach. If it's flat or 5V panel, a good power nibbler can do it as well. And the nibbler will heal the edges so they won't rust. But they are not common tools and take a little practice to work with. I have a 40 year old nibbler that I use once in a while and it makes quick work of cutting sheet metal.

Does the roofing material still work if it's not perfectly straight? I think it matters more about how and where you put screws than if it's absolutely perfectly straight? And straight to what? Each panel or the eave or the drip line or the fascia board. Being straight and looking and functioning fine are basically the same if the house is square and if it's not square then does anything being straight even matter

Some people put screws on the ribs, but it is by no means the accepted way and it is not appropriate for all gauges and panel designs. I get asked this so much, I made a video on the topic: kzbin.info/www/bejne/Y6bHfaOvfd2oZ7M The manufacturer of this panel specifies fasteners to be installed in the valleys with a screw next to each rib, and two screws in the valley along eaves and overlaps. Other manufacturers follow the same guidelines for a bunch of different panel styles. I have not run into any manufacturers that specify putting screws into ribs. Some specifically caution against it because there is inadequate sealing pressure under the washers and/or not enough fasteners at eaves and overlaps to provide proper wind/uplift resistance. So consult the manufacturer’s install manual for your panel type and follow their guidelines.

Once again, the screws are on the flat where when, not if, the rubber washers shrink and crack, where do you want the screws, on the flat where there is a ton of water flowing over it or on the top of the rib where very little water gets to it?

Some people put screws on the ribs, but it is by no means the accepted way and it is not appropriate for all gauges and panel designs. At eaves, you will have 2X fewer screws if you only fasten through ribs. And in locations where wind uplift loads are high, you cannot get proper retention with screws only on the ribs (there won't be enough screws). If you are not taking all of that into account then you are missing a whole lot of technical data. The manufacturer of this particular panel specifies fasteners to be installed on the flats except at the ridge where they are to be put through the ribs (to attach ridge trim). I recommend people understand the technical data and follow the manufacturer specs for each panel type. This is especially important if you care about the roof warranty.

Those are both bad pieces of advice -- this particular roof panel calls for screws on the flats per the manufacturer, as do most modern panels. People should follow the manufacturer specs for screw placement if warranty and fastener performance matter. And you never want to cut a steel roof panel with a grinder or rotating/reciprocating blade because it will compromise the paint and cause the edges to rust. If you have to make cuts, use a nibbler tool, which will work harden the edges as it cuts and prevent them from rusting.

- Grinder is always a tool to avoid in mechanics, it heats the metal and modify the surface (see heat surface treatment ...) - Screws on low points; I am less convinced. Stronger fastening sure. But drips of water more probable; I would apply a layer of linseed oil on the wood.

I don't exactly know how I am going to stretch those boards. The roof is about 38 feet wide total with the middle being about 8 feet tall being the middle length of the right triangles.

Actually, you are more likely to get leaks with screws on the ribs with this type of panel -- there will be inadequate seating of the sealing washer due to deformation of the metal.

Other manufacturers follow the same guidelines for a bunch of different panel styles. I have not run into any manufacturers that specify putting screws into ribs. Some specifically caution against it because there is inadequate sealing pressure under the washers and/or not enough fasteners at eaves and overlaps to provide proper wind/uplift resistance. So consult the manufacturer’s install manual for your panel type and follow their guidelines. This is especially important if you care about the roof warranty, wind uplift loads, sealing the screw heads, and fastener retention. There are many scenarios where putting screws in the ribs will adversely affect one or more of these factors.

35 yrs ago suppliers were telling us to put screws in the rib on the roof, and in the flats on walls. But now every supplier that we use tells us to put all screws in the flats, roofs and walls or the warranty nullified if the fastener is on the rib. But in 40yrs we haven't had a callback on either method.

The oldest ones I have put up are going on 30 years old and still seem OK The key is to not overdrive the screws and smash the rubber so that it squirts out from under the washer.

I have fixed roofs put on by other people where the screws were overdriven so much there was a dimple in the metal (not good, attracts water) and the rubber was all smashed and cracked. Bad news.

Great question. In general, it doesn't matter which direction you go in, you just need to make sure you are lapping the panels properly. There is a very specific overlap rib and underlap rib on each panel. The underlap rib goes down first and the overlap rib of the next panel goes on top. But a good roofer will also take into account prevailing winds and/or visual exposure to decide what direction to install in. If you can arrange the joints to avoid facing the prevailing wind there will be less chance of issues from wind and wind driven rain. And if you can avoid the joints facing the street or typical view direction, it will look much better. So try to factor that stuff in to determine the direction you install, and then orient the panels to get the lapping order correct.

This panel style usually comes in 28-29 gauge which is what I used here. It's fairly stiff because of the rib pattern. You can curl the panel between your hands to make it stiffer when carrying or getting onto the roof (also makes it slide across purlins easier).

Using a modern screw with domed washer and modern gasket material (they no longer use rubber), and properly installing the screw, you're looking at 40-50 year life span of the gaskets. But many people install the screws wrong, compromising the gasket, and they may see leaks in as soon as 10 years (or right away if they really mess up). It's a very important detail to get right.

Going 2" off and using a measuring tape will be very precise. I usually setup a ~1/8" gap between panel end and string -- it's easy to eyeball and follow down the line. It will force the installer to keep within a tight visual tolerance and correct variations in realtime before they become a problem.
