[@RainMaker94]

Good info, Don’t forget to pre drill your screw lines on the metal, keep them straight. And use master flashings on chimney and plumbing flashings. Another note is to use enclosure foam along the eave under the panel to prevent moisture and debris from blowing up the rib and under the panel

[@RoofingIntelligence]

Good tips!

get self drilling screws so u dont have to waste time with pilot holes

[@RainMaker94]

@@DSkimRS pilot holes take less than 10 minutes and can turn your job from a farmers quick and dirty to a professional quality job. Straight clean lines make a world of difference. You’ll never be able to eyeball the screw lines straight ans if you’re measuring or using a chalk like as you go you’ll be wasting far more time than piloting holes while your metal is still in a stack on the pallet.

Pre-drilling is not required when you use a impact driver.

[@Farmboy2917]

I just finished one side of a 48 by 16 foot roof on my mother's bungalow , 4/12 pitch, using 28 gauge panels 3 feet wide . I did not pre-drill The first few panels and found that I could not drive the screw without marking and punching the hole first . To do this I had to work on my knees with multiple tools in my hand , and I had to build a jiffy roof ladder to support myself. The final panels were marked and pre-drilled in a stack of 6 panels . This made it easier to line them up on the roof , and most importantly I could drill by standing over the holes with just the screw and driver to deal with . It took only a few seconds to drill each hole , compared to over a minute per hole the other way , and there were no filings around the screw head.. The manufacturer recommended ridge drilling , and every house in our Canadian town had ridge drilling . So , always pre-drill.

Use self tapping screws and make sure they have washers on them or they will leak

[@markmarkw1919]

@@iluvdrywall I dunno; maybe all metal-roofing screws are made self-drilling by default, but if yours aren't you'll probably dent the ridge tops trying to get them to puncture the metal to where the threads can grab. I'd definitely test this out on some scrap first.

[@cadiehl1]

I’ve read in MANY places that you should never predrill.

[@scottiestarcher409]

Do you use longer screws? Or do just the tips of the screws hold the metal panels on?

[@LiamG903]

To put an end to the debate of flat vs rib. We built two 18x40 sheds, one went on the ribs the others in the flats, after 15 years the flats have had a few leaks and needed more screws replaced. The ribs have been leak proof and have not needed any to be replaced. Always screw on the rib, never on the flat.

[@robtmohr]

I was really confused why they’d demonstrate that screw location “for a roof”. For a wall, screwing on the flat is fine, but for a roof I’d never screw on the flat.

[@LiamG903]

​@@robtmohrI know, I'm in the northern Canada and no one ever does it in the flat, I asked about 5 different roofers and they all said we've done on the flat before like they said and they always have issues. You just have to be careful not to over tighten on the rib

[@DominatraVon]

Never screw on the rib. Expansion and contraction will move that screw back and forth and loosen it over time. Unless you want to use 3" screws. Also roof rakes will hang up on all them screw heads sticking up. And another reason is that it bows the rest of the panel up and deforms the ribs. Its almost impossible not to. Just don't do it.

[@LiamG903]

@@DominatraVon like I said we did it to test. Flat will leak, metal doesn't move under, you have to be careful to to tighten just to comoress the washer and not pull on the rib. Snow rakes do with the top but we now use the snow cutter with the plastic slide. Works better anyways. Now screwing on the flat where snow and ice melt and refrezzes all winter long is where the failure seems to be happening the most when people screw on the flat. You can do both but here in the north where it hit - 40 and plus 35 the flat method just seems to fail more often. Take your time and screw on the rib and you'll be in a better situation. Screwing on the flat is easier but up here everyone learned their lesson and all kn the rib now

I've put screws in both ways. the screws loosen up over time. I fine it better to use seal tape on the over laps and screw on the ridges. Also the screws in the flats cause leaks and catch leaves and cause build up over time ! I removed old shingles use 30 lb felt installed with no furring strips (flat on roof) and used inside closers at the eves ! I had an Insurance adjuster comment, he had seen several metal roofs come up after strong winds (the closer strips prevent that).

An easy way to keep the screws in a nice line is to use one of the spring retractors commonly used for keys, security cards, etc and use a magnetic hook on each end. The magnets commonly have a hole in the middle that sits over the previous panels last screw and put the other on the metal center of 2x or a chalkline.

I am a roofing contractor where there is snow and Ice build up. I have lost count how many rotten facia boards and bottom of the roof deck I have replaced when Lazy contractors just strapped a old asphalt roof and didn't think about ice build up or condensation forming under the metal. I always recommend tearing the roof and installing a proper high temp underlayment. Plus you don't have to worry about water overshooting the gutters.

[@marthinuscilliers3726]

Hello Shawn. How about if I tear the old roof off down to the deck, lay down 30# felt, and then install the panels flat on the felt? I didn't put straps down... Do you strap it even if you tear the old roof off? I ordered synthetic felt with my material, but the order got messed up and I didn't receive the synthetic felt, so I bought 30# locally.

[@karlschwab6437]

Fantastic video! I am planning on having a metal roof installed on a gable roof at our home in northern Michigan.

I will hire the work to be done, but with your video, I will know what questions to ask the installer to see if they know! Thanks again.

[@coreyhamby2989]

Karl Schwab metal roofs are great but asphalt architectual shingles if installed properly should last 25-30 years in any conditions. Also if you are set on metal i would strongly consider Standing Seam. It has no visible fasteners and looks amazing and lasts much longer than 5 rib. It will cost more but be well worth it.

[@w8what575]

With snow and metal roofing…when u get a heavy snow, ur gonna have to make sure u can budge the snow so it slides off right. Away because if it’s allowed to melt a bit and then refreeze, it creates a dangerous situation..,that sheet of ice will come down suddenly and can injure or kill someone quickly…this is one disadvantage of metal roofing in snow areas…otherwise metal roofing is the best way to go…lasts a lot longer

Well done Sir . Said with finesse & no fluff!

[@chrislutz9342]

I have on a few occasions installed insulation (EPS or poly-iso) underneath the metal but in these instances I still used the wood strips over top of the insulation. While the fan fold would do well to insulate and separate the metal from the decking or shingles, it would not accomplish several of the important tasks of the wood strips. These include: 1) Establishing a solid and dependable surface to attach the metal to. 2) Creating an air gap beneath the panel to facilitate better ventilation

Just been watching my neighbor two doors up from us having the second asphalt shingle roof installation in about the last 12 years. Our metal roof has been in place since 1999. It's still got a few years left on the paint warranty. Meridian panels by McElroy that cost us about $3,500 in materials for a 17 plus square roof. That's about half the cost of the crappy asphalt shingles the neighbor is going having installed for materials. It makes no sense to me why anyone favors buying new roofs every 15 to 20 years at increasingly expensive prices based on oil when metal roofs can last lifetimes. Our energy savings in the summer have paid for the metal roof at least once already.

Never ever put screws in the valleys. Always on the ridges. If u put them in the vally you will always have problems over the years..trust me I have a 100 yr old roof

All because they work some place doesn't make them an expert. I'm just saying what I know after owning a 100+ year old home with a tin roof for 30 years. I've had a roofer 30 year vet do my roof when I was sick and I'm still dealing with screws in the valleys. Once you put that whole in the vally it will always be there no matter how you cover it. Tar & fiber seal is only a band aid

[@Beandiptheredneck]

off2f it’s an ongoing argument and honestly it doesn’t make a difference. The screw is holding out water no matter where it’s installed, and if it’s not then it needs to be replaced regardless of where it was put in

Think what you want. I'm going by what I have learned on my +100 year old house and I've never had any problems until i got sick and had to get a roofer to work on my +100 year old roof and he put screws in the valleys and ice dams habe caused problems all the time, you can say I'm wrong all you want but I lived in this house for over 30 years and always took care of it myself and never had an issue until i got sick and had to get some dum half wit roofer to coolseal it and he thought it need screws in all the valleys where there was never a nail let alone a screw

[@Beandiptheredneck]

off2f I’ve installed numerous metal roofs (that don’t leak) with every screw in the valley, your roofer did something wrong if it leaks after putting screws in the valleys. And it wasn’t putting the screws there that caused the leak

To those asking why not screw on the ridge, or saying that screwing on the flat is wrong! The Panels are metal, and will expand and shrink from temperature changes a lot more then you would think. Hot day the Panels will expand. Cool nights the Panels will shrink. The rubber seal under the screws washer can be damaged (WILL BE) when the Roof Panels contract over and over from temperature changes Day to Night, Summer to Winter! The Ridges will put excessive stress on the rubber seal during this process. When the screws are installed on a flat surface this expansion from the temp. changes will not add stress on the rubber seal. I have seen this Incorrect Installation myself, morning roof cool the metal shrinks, now the rubber seal is not making contact to the panels and can be turned by your fingers. (Now if it rains the rubber seal not tight enough and leak) Sun comes out the Ridges will expand and now the rubber seal is over-tight on the ridge. (The over tight seal will be cut or tore or ripped and will leak) Then after rain comes and the rubber seal has been damaged. Just a very (Note: just a very) little water will seep down the screw and rout the wood just around where the screw is anchored down. The next good wind comes along and will blow the roof panels off. Because the screws have nothing but rotten wood to hold down the panels. There may be a Manufacture making products (not aware of) that are to be screwed down on the Ribs, but never seen a manufactures installation instruction manual saying this. Watch the video where Roofingintelligence made it very clear how important to have the correct torque on the screws. ALL WAYS FOLLOW THE MANUFACTURES INSTALLATION INSTRUCTIONS!!!! THERE IS A REASON!

[@jimmydean4586]

so I will tell you this from experience. Manufactures want you to screw on the flat for 2 reasons. It is easier to get a proper layment of the panel and they want to sell their newer more expensive products. If you are experienced enough you can place the screws properly on the rib and this is the best way to go for many reasons. As he stated the roof flexes and moves. with the screws on the rib it allows the roof to flex. On the flat it causes far more resistance to flex and will cause the screws to either back out. damage the washers or even break the screw heads off. When going through the rib I use 2 inch screws to solve the issues he demonstrated. when on the rib pre drilling helps prevent problems. If you have a faulty screw on the rib will leak 99 percent less than a faulty screw on the flat. I predrill only on the laps and trim pieces. I started putting through the roof on the threads of the screws just after they penetrate the metal. Do this right and your screws will remain water tight for over 60 years,,, do it on the flat and I can guarantee you are replacing most of them in under 20 years. Also never install exposed fastener panels without purlins except in buildings that are not heated. NEVER. I have repaired so many roofs that were screwed on the flat....

Hi, how did your roof install go, did you run into any problems? I have yet to install. I'm still repairing the deck.

[@ausfarmer89]

Thirdly, a lot of information in the US talks about replacing the rubber washers about every 15 years. This is something that never has to be done in Aus. I think this idea of screwing through the flat comes from an installation point of view, it is much easier to screw through the flat and you don't have to worry about over tightening the screws and getting the sheets out of square, so less skilled labor can be used. The problem is you are relying to heavily on the washers to seal the roof.

No, many of these panels don't have a flat area on the top of the rib. They are rounded, and a screw will not seal on these crowns. The manufacturer tells you too screw on the lower flat area. I've installed a few of these. They don't leak if you install them as shown in the video.

[@tonystark614]

Okay, you yanks are clearly using a cheaper inferior product. Who is the manufacturer and what is the product name? I reckon the metal on this product is thinner than used in Australia and the profile is also inferior - probably cheaper to manufacture a sheet with a rounder ridge top than to put 2 folds in the metal to create a flat ridge top.

[@coreyhamby2989]

Tony Stark It all depends on what gage metal you want to buy. Obviously the thicker the more expensive. I pwrsonally would not wven use this type of metal for my house as there is much better out there. Standing seam is the way i would go. It is very thick and there is no screws exposed whatsoever. It makes for a very clean look that lasts forever.

[@affordabledesertliving3487]

Excellent. Specific and to the point which is so helpful.

[@RoofingIntelligence]

A common question. There are a few reasons why we don't put the screws in the top of the rib. This type of panel in not designed for that application. The top of the rib is rounded and does not provide a flat, secure place for the screw's washer to seat and seal well. Also, putting the screws there causes the panel to 'fishmouth' slightly at the bottom, causing unsightly gaps where the panel meets the drip edge trim.

[@certaindeed]

In 50 years our company has never had much luck putting the screws in the low spots. You are relying on the rubber washers to be your roof instead of the the metal and it's shape. That negates 30-40% of the advantage of the metal roof. We have a couple of roofs 60+ years now and still going strong after paint jobs and inspection (we did these in the days when there were juts nails and no screw washers and there was just galvanized). The other roofs with the screws in the low spots have seen trouble over the years. If the roof is not pitched enough they leak like a spigot. If an ice dam occurs they leak like a spigot. If you put them on you high spots to are assured a minimal ice dam resistance the height of the corrugated. If you put them in the low spots you do not have this grace/advantage from the metal roof itself. Worse, Screws in low spots get in the way of serviceability and leak when you have to go on the roof 10 years later when you have to go up and do repairs. You cannot put you knee or brace boards to distribute weight in the low spots without causing the screws to leak and damage, I also strongly recommend always setting the metal on a full flat surface and the solid roof and not to use runners. Always strip the asphalt roof! Not only is it stronger and better mounted, but it is hurricane and high wind resistant,to the air lift underneath more immune to bending under heavy snow loads and impact (tree limbs ice etc etc) ...and more importantly strong enough to be Easily SERVICEABLE when you have to got on the roof at various times in it's life because you can actually put full weight on the flat spots.without opening joints or bending the roof.

[@certaindeed]

***** I've never had any steel dimple or dent on the ridges when screws were put through. Aluminum is easier for that to happen. That said...yes you have to be careful and practice when torquing these or it can bow up the flats. This entire debate over where to put the screws is attributed to the thinner, higher strength materials which effects the installation process/time and skill to install etc.Putting in the flats also allows the metal roofs to be put onto runners with much fewer fasten points, which again is cost of installation instead of having a shingle less solid surface underneath. Can't see how your job came out but as it is a steep roof and shed...and a practice run for you? I would not worry too much. If it is really bugging you how it came out...Might be nice to do one side one way and one another if you want the experience and would be nice to see the comparison results in 10-15 if we are all still around...

[@kris8491]

+Harry Brown I doubt you will have any issues with the screws installed in the ridges. I did an entire roof this way and there were only 2 downsides that I could find about doing it this way. 1. I found it somewhat difficult to get enough pressure to start the screws in the ridges and sometimes I had the screws slip when trying to initially penetrate. This could be due to how hard the panels were, not sure. 2. I found myself getting pretty far out of square with this method. I was attaching the panels from the top and I didn't realize that I was tightening the upper screws too much when I was putting the panel in place. The grommets around the screws were not indicative of them being too tight, what was happening instead was the pressure on the ridges was bringing up the flat portions of the panel. It was very little per panel, but after a few panels it started to get pretty noticeable. I was able to rectify some of this by over tightening the lower screws later, but I think it could have been avoided had I put the screws in the valleys.

[@Cotronixco]

It seems that way, eddie, but in real practice that is untrue. All my buildings have the fasteners in the flats and even after 20 years not a single leak. But the main reason the ribs is a bad choice is they provide very little fastening strength and virtually no triangular strength to the building.

[@Cotronixco]

+voluntown - Installing the fasteners in the ribs means all fasteners are loose, and after 40 years many buildings have moved extensively and have weakened especially in the wind. With good fasteners, installed in the flats with the correct torque, you will get 40 years easily. Replacing the fasteners after around 30 years is also quite common. If you want strength without maintenance, go with hidden fastener steel roofing choices.

Great video series. Now seeing it after it's been up 11 years now. I'm in the Caribbean. We use metal roofing on nearly every house here. However we don't use the screws in the valley of the sheeting. The reason is the rubbers on the screws are never installed perfectly, and being rubber under high temperature daily, they disintegrate, so we use the screws on the top of the ridge. Trust me a metal roof is the best. However when I lived in Florida, it seems they use obnoxious rules in building codes to prevent you. For example they said my house needed a 2:12 pitch at least. Why you ask? It's all about what drives the economy. Roofing repairs are big business. A metal roof could probably last you 50 years, while you're changing shingles, and asphalt "roll roofing" ever 12 years or so...15 if you're lucky.

[@dmonk926]

Where I come from they often use currogated metal sheets, and common practice is to put screws through the crests (the ridge) rather than the valley part as water running into the valleys with screws makes the roof more leak prone. Is this not a concern for sheets with an angular profile and larger distance betwen ridges like in the video?

By stripping the roof, you just made the roof noisy, the hollow area will make a speaker, when it rains you will hear it. Fill the cavities or lay flat on the existing roof

[@shevinsacrey5862]

What I don't understand is why did you say the importance of running the screws vertically beside each rib first, and then in the next shot you are screwing in all of horizontals without having touched the verticals.

[@vinny6_9]

would be nice if you had a ridge cap video as well! i just put the panels down thanks to your vid, and now waiting on the ridge cap to get here.

Hi, Ive just done my conservatory roof using the 100mm (4") insulated steel sheets and really it was so easy and its so strong i have a span of 2.7m (9') with only end support and i can walk on it

[@InventPeace1]

15:17 By a simple rip, you leave a loophole that can leak ie with rake on to come over and with butyl tape seal off, eventually there will come a time when the butyl tape will leak or other imperfection, rain can (in bad storm with sideways /diagonal rain) be forced under the rake and go to the edge, leach around the edge and destroy your wood decking on the roof edge); its better to leave 1" extra over the edge , bend it back on top of itself to where its below 1/2 " high, so you have an extra rib manually made just where you need it on the edge underneath the rake, giving you double protection for only a quick bend back over time & effort.

[@lonnieclemens8028]

This is a good video. Thank you for sharing.

[@w8what575]

Always screw down the panels like he suggests to do it! I’ve worked with someone who just slapped the roof on and screwed them down in the corners to finish screwing it down later and he had to basically start all over because it made the panels ripple

[@David-zv2em]

I am replacing the existing flat roof over my two car garage because of water damage to the top as well as the plywood sheathing underneath. Q1: Can I install this metal roof panel over the joist or do I need to install new plywood sheathing over the joist and then the metal roof on top of the plywood? Q2: If I install the metal roof over the plywood, do I need to install anything on top of the plywood before installing the metal panel? Q3: Do I need to caulk or seal the top of the fastening screws to prevent any potential water leak?

[@construction010]

Hi , here are a few reasons why not to screw fix through the flat part of the roofing panel - it causes leaks - it does not compress the laps i.e more leaks - it is against manufactures installation instructions i.e voids the warranty - in New Zealand and Australia you would instantly get the sack and be liable to replace the whole roof.

I sure wouldn’t trust an instructor who advocates puncturing the trough of the panels. Those rubber washers won’t be a perfect seal for long, if they ever were in the first place.

[@andreww6676]

Cladco official fitting instructions state using the flat trough for a u profile and the crest for a curved/traditional profile. They also ask you not to rely on standard fixing for longitudinal lap but sheet tape and or stitching screws

[@Mike_from_Canmore]

Wow. I dont use the wood underneath I just nailed it all down Then I siliconed all the panels together and over the nails. I left about 8 inches overhang to save on buying the metal edge parts.

[@josephseewald4687]

In your demo, you never did install any foam closure strip underneath the panel on top of the nailer strip, was that just a oversight for the video or are they really optional? Are they to be worth buying and installing? Thanks

[@cynthiamoon372]

Unless it is a roof over an open sided pole barn, I’d sure as heck want something to keep nesting hornets out of the attic.

[@johnvescovi9934]

Thanks for the tips

[@mkrug1149]

I still like screwing on the ribs, those 2-3 cent washers will not last forever, and will leak more in the low part vs. the rib. I predrill the panels on the ground with a sharp bit.

[@alanjbuddendeck186]

Helpful information and insights. Thank you!

[@moofushu]

It looks like you're installing 4x8 metal panels on a 8 foot long roof on one side and 8 feet on the other. What happens when you have to install 4x8 metal panels on a roof that is 24'x32' on one side and the same on the other? How do you handle the overlap and how do you walk over those metal panels? On a larger roof you have to move around and can't simply lean over the roof like you do in this example. How much do you overlap the panels on the vertical?

[@w8what575]

The metal panels come in different lengths and can be ordered to length needed…otherwise u would want to start laying the shorter panels from the bottom edge of the roof moving up so they’re layered like shingles would be to avoid water from getting under the panels…use silicon caulking or something similar between the panels to keep them sealed up

[@w8what575]

The nonslip rugs u buy for time flooring or whatever…i used the cabinet non slip material before to keep from slipping…I really don’t like walking in the metal panels but it’s unavoidable in large roofs…at one point, we were trying to fix an area where there was an issue and I was the only one small enough to get to the area so I took off my shoes and walked around barefooted to do it…but it was a cooler day and the metal wasn’t taking the layers of skin off my feet either lol

[@richardvalitalo3670]

The only way to get 1st panel square is using the 3-4-5 & square to the eve straight line. I measure & start in the middle. I also predrill & use 2x4 strapping.

I have a similar hearing problem after fixing cars as an ASE Master and in 1978. They never thought of gloves, eye or ear protection (PPE) back then. Today, it depends on the iPhone as this 14 mini I received from my son out of state. It is much louder than the 6s I had. Had not owned a cell since 2008, tech changes with hearing aids then ear buds! I tried "Ray-Con". Sitting still, one quit then second. They may be fine but they don't warranty 3rd party or online sales. Best of luck!

[@chrisbrady9122]

Do you have to build a box around your vent pipes underneath the metal so the screws will catch I'm doing a metal roof over a tin roof on a single wide I did the firing strips and insulation in between the furring strips I have another vent pipe so if I need to do it then I need to do that one right

[@petercraw8188]

What is the best way to plug or repair screw holes? I have several salvaged panels I’m going to make a 12’ X 15’ storage shelter for my tractor and I’m going to have lots of extra little screw holes. Thanks. Great video.

[@polarlab113]

I had used metal for my barn.instead of filling the old holes I used them by trimming the panels to match the strapping underneath.or you could install the strapping to match the holes.mine was a reroof job so I cut panels to match the holes.I guess you might waste too much roofing but I had lots of length.another method you could use is to sheath the roof with OSB or plywood and use all the holes.in lieu of that you would use a quality silicone sealer and fill the holes

[@randy8672]

Shoulda ran the nailer the direction of the rafters first, then run the second “top” nailer parallel with the long side of the trailer that way the roof can breathe so your daily condensation will evaporate. This would also give you the ability for a longer overhang and a way to attach it. Keep clowning.

[@liberalssuck3155]

The highs of the sheets dictate if it requires a stitch screw or not

[@chrismanno1168]

How far apart do you put the 2x4s? Great video by the way. Really good stuff you have here.

[@otakop67]

+Chris Manno Most of the videos I've seen on this use 1x4s and space them 2 feet on center. What I've also seen (and seems like a good idea) is to use 3/4 inch thick foam board insulation (Mylar backed) in between the strips. A 1x4 is actually 3/4 x 3 1/2 in size. It acts as support for the metal panels when you need to step on them so the screws don't elongate the holes, fills the void so strong winds can't lift the panels from underneath and adds insulation.

[@polarlab113]

1x4 is ok for a shed or lean to depending on slope.if it steeper then 1x4 is ok .on a low slope I would use 2x4.and on a house the optimum would be 2x4

[@michaelw.urbansr.8617]

I have a question about the bottom of the vent cap or pipe cap. There is no screws that do into the corners of the horseshoe cut roof piece that covers the top of the pipe vent,cover? At about minute 14:25 to 15 when your start talking about the install of the last roof piece. It shows the horse shoe cut in the roof panel with no screws to anchor it? Is that meant to be left unscrewed or screwed and you just didnt address it in this video? thanks informative

[@RoofingIntelligence]

Great question: NO, don't put screws there. I see why you would want to but this area is vulnerable to water getting in under the that top panel and then leaking in the screw holes underneath the panel.

[@willkeen5010]

Excellent video. Do you have any info on using the f gable trim that goes under the metal panel and how they are tabbed and lapped to flow water properly. Any information you could provide would be greatly appreciated.

[@RoofingIntelligence]

I'm not exactly sure what you're asking but I have videos that cover all aspects of metal roofing. You should check out the ones on drip edge.

[@amybrecken161]

If the run is long stack up a few panels and pre drill

[@stuart8219]

So you don’t strip it unless u have to .. the dead air space causes moisture.. as well as vapor barriers.. it’s best to run straight over the shingles for best results do they roof can breathe and no hollows for noisy rain n etc .

[@amoebacakes]

why is Billy Corgan teaching roofs?

[@allaneves180]

Thank you SO MUCH!!! for the DETAIL of the screw placement, and details like taking the time to wipe the chalk line chalk down after. You showed to put the screws on the flat of the sheet. Not the hip (rib) I can't tell you how many roofs I seen (and done!!!) where the screws are on the rib. The bottom screw will be on the flat, but rest will be on the rib. Again Thank you

[@jeffreykbevins7116]

I totally refuse to place the screws down in the flats of the tin. I measure where that each of the sheeting boards are to the center of them, up and down the roof all the way across the roof. I stack all of the sheets of the tin together and clamp them together and then mark all the measurements of the sheeting boards on the top sheet of tin and then predrill all the holes, in the tops of the ribbs, and put the screws in the ribbs like has been put in the old type tin for maybe a hundred years or more, making sure that they are squared across the sheet of tin,( to keep your screws all in a straight line all the way across the roof) for the screws with a smaller drill bit than the size of the screws. You do not drill holes in the over lap row for the side that will be the underneath sheet of tin. Then put the first sheet of tin up on the roof and get it squared in place and put the screws in the holes and you have to learn not to tighten your screws down to make the tin expand in width. Then put the next sheet of tin on in place and continue across the roof. And I guarantee that you will never have a leak by a screw that backs out like it does down in the flat of the tin and let's water pour down in around the screw like a funnel. Cause if you take your time and measure and predrill your screw holes and center them in the tops of the ribbs your screws will seal down and never leak. I have worked on several roofs, where that the screws are down in the flats and the home owners have had all kinds of leak problems over time and I have never had any problems, with putting screws up on the ribbs. And I have several buddies that do just like I do, putting the screws up on top of the ribbs and premeasuring where that the sheeting boards are and premeasuring marks on the tin and predrilling holes for the screws. And I always use 3 inch long screws and 1 and a half inch thick 2x4's or in some places maybe 2x6's to go top of plywood or 1x12 sheeting boards, on an old roof. And 2x4's on top of the rafters for new construction. A little extra work, but after you have done it a few times my way, you can get fast at it and move right along. And you will have a better roof with no worry, problems. As always, Jeffrey !!!

[@tonystark614]

What do you call the profile on that roof sheet? It looks like trimdeck. On trimdeck the top of the rib is basically flat and in Australia you always screw into the top of the rib because any rain will runoff into the wide flat valley almost immediately. From the comments it sounds like the top of the rib on this profile is rounded which isn't obvious in the video. In Australia a corrugated profile is mostly used and again is screwed on the top of the rib which with corrugation is rounded. A corrugated profile is used on steeper pitched roofs (more than 20 degree pitch). Trimdeck is used on flat roof pitches (5 -20 degree pitch). A pitch of less than 5 degrees requires clipdeck with no screwing - clips are mounted on the roof frame and the sheet is pushed onto the clips to be held. I would not screw into the flat as this is where all the water is diverted too and any problem with the rubber seal will mean a greater quantity of water penetrating the roof sheet. At least on top of the rib a fault with the seal will only permit minimal water entry as the sheet profile quickly diverts water off the rib to the valley/flat.

[@tonystark614]

Confirmed by watching another American video. This American roof sheet is cheap junk by Australian standards. Initially it appears to be a trimdeck profile but a closer look shows the top of the ridge is rounded and the ridge height looks to be around 25mm whereas trimdeck is around 39mm from memory. Also based on the amount of flex in this product when being handled it appears the metal is much thinner than used in Australia. My conclusion is they screw in the flats to compensate for the poor quality of the product they are using.

[@RoofingIntelligence]

This is a common question. This can work but I don't recommend it for a variety of reasons. If you're going back with any new panels, put them in the flat of the roof as I describe in the video.

[@neil00681]

Common mistake # 6. NEVER PUT A NEW METAL ROOF OVER SLEEPERS. It is a fail every time. Especially in snow country.

[@trinifirst6702]

You didn't SHOW how you installed the final piece of panel especially since it was uneven at the top and bottom. Also I see you're installing over existing shingles. Is that allowed under building codes? (I'm in Florida). Would it make a safer roof if the panels were resting directly the flat surface of the roof?

[@joshuaderstine4133]

Pick a day that's not too windy to do this. The wind can pick up one of these sheets and toss it. It can really hurt somebody.

[@thereskent1115]

House has a flat roof. No attic or crawl space for duct work and therefore the house is crazy stupid hot especially in summer here in FL. I would like to know the basics on what options are to get some lift on the roof. If not for creating a crawl space; to atleast give lift or create additional distance between the old & the new roof. Which the new roof preference is metal.

[@markpalmer7832]

I did Channel Drain, then later I learned standing seam...I agree...no fasteners in flats.

[@danbasta3677]

This metal roofing is exactly what I want to do for my home and detacjphed garage I have.

[@InventPeace1]

15:30 put screws on top of the ridges, pre-drill exactly on top for screws to be exactly on top of the triangle ridge minimizing leaks in the valleys where every raindrop can leak at a bad washer screw point , remem: all washers eventually crack and leak). so on top means only a direct hit from a raindrop even has a chance to leaks, paint the washers after install to minimize sun drying out, re-chk ev yr , retighten re-paint as needed.

[@RoofingIntelligence]

I think that is a big mistake. Installing the wood strips is one of the most important steps in installing your metal roof. The strips provide important holding power over the OSB that most roof decking is made of. Check out my video series to watch an entire section on how to install the wood strips.

[@stevewilson2158]

Osb is garbage to screw to...cover with tar paper then skip sheet with 1×4
