Great effort guy's I have a couple tips.
1. Use self supporting paper and pull it tight.
2. Use a string line into the gutter to get a straight line, laing the roofing iron.
3. Tack the roofing top and bottom, bottom being a consistent measurement, top being under the head flashing. Chalk line the rows after the iron is installed, then remove screws from the to to install head flashing. This gives you perfect straight screw lines.
3. Great never over lap a sheet more then needed, it will definitely condensate and corrode.
4. Stop end the sheets on the ground, 3 sheets at a time. Cuts your work down tremendously, especially if you have 50 sheets to install.
Other the that, not a bad job guy's. Thanks for sharing 👍
Awesome comment
These are super helpful tips thanks for adding this comment 👍
thankYou
I would use foil under all roofs in any situation no matter if its a closed building or not, when the moisture is on the underside due to cold mornings and the sun comes up it heats the iron which causes the roof to drip, with foil it does not, I have proven this myself as i have a variety of roofs with and without foil.
actorzone thanks for your feedback
Advice to anyone getting a metal roof fitted. NEVER fit it without an insulation blanket, foil alone is no good unless it’s just a garage. Must have the insulation blanket to suppress mechanical expansion & contraction noises during the day. Learned this the hard way. Don’t let the contractor convince you otherwise.
Thanks for an excellent video - the tip about turning up the ends with pliars was one I'd not thought of and is gunna save me a squillion in silicone sealant! Cheers - Simon / Adelaide
Simon Trangmar glad we could help!
Very informative, great job Sean.
Thanks Sunstate roofing services. Happy roofing 😀👍
I get a bit of blow back (if that’s the right wording) under the end of the sheets. You can see the staining on the timber from the water where it tracks back from the end of the sheet where it over hangs the gutter. I have a 10cm fall over 5 meters. What is the best thing to put in place to stop it or how do you bend the end of the sheets down on the lower part of the corrugated sheets ?? (Love the videos by the way)
great videos guys I just had a delivery from metal roofing online and I have gable rolls to install but can't find any vids about that
Hi Robert, Thanks for your order. At this point in time we have not done a video of installing the barge gable rolls. We have done a similar video though, which is how to install the barge capping. Hopefully this helps 🤙
Enjoyed the video but shouldn't the wrap be installed parallel to the gutter from the bottom up? And also installed nice ans tight?
The way this foil is installed, if any water gets under the roofing and there's any wind, its going straight through the vertical join of and into the ceiling cavity.
Doesn't condensation drip off the underside of the metal, onto the saggy vapor barrier, and then run down into the house???
I agree. Surely the condensation pools in the drapped material. What is the membrane you have used?
I don't think so.
Not enough temperature difference also the sisilation is a moisture barrier.
What is the length of the screws that you use for corrugated iron, great video guys.👍🏼
is it worth running the metal mesh under the foil, or not needed?
Why have you put the paper the same direction as the tin? Am i missing something cos i lay the paper from the low side and work up so that condensation always runs over the overlap and cant find a seam to leak. I respect the pros, but can you clear this up for me?
I lay paper horizontal on low pitch roofs. Steep roofs it doesn't matter has a 150mm lap and the condensation runs straight down
I’m about to use this roofing soon. Please can someone answer a few questions from a novice?
Is this roofing metal rust proof? If not, how do I get it rust proof?
Paint it? What kind of painting should I use?
How long can these sheets last for in a hot humid weather? 5years? more?
And how do you paint this kind of roofing? Paint it before nailing them on the roof? ...is there a good technique to paint these iron sheets when they are already nailed? Like how do you make sure the paint can stay on the roof without slipping off and spilling?
Help please with any useful tips..gonna watch your other videos ❣️❣️
Hi there, Sorry but I do not have allot of knowledge on painting metal roofs. You should be able to get all the information you require from a paint shop. We do only use Australian Bluescope steel which has a 30 year warranty. Kind regards Darren, Metalroofingonline
These are Colorbond sheets - colorbond.com/products/roofing
Even the basic raw corrugated iron sheet was galvanized which meant it is rust resistant and should last decades. It would probably outlast any paint you applied... 🤣
The new Colorbond sheets are available in a range of colours and have the paint baked on. colorbond.com/why-colorbond-steel Check out the 5 layers of protection! Basically, choose your colour, screw it on and you're good to go. It's way more rust and weather resistant than any paint you can apply!
I didn't get the point about using foil or not. When do I use it and when don't I? Thanks nice video
Hi Matthew. I would recommend using foil when you have an enclosed space, like a garage, shed or house. And not using it when you have an open space like a veranda or carport. 😃
I would suggest always fit foil.
An open spaces like carport will get very hot on the roof and then radiate that temperature down, like a heater.
Good vid.. what about cutting hips? Do you ever use a grinder or only snips? Thanks
Beautiful Bastard thanks. We either use our electric Excalibur’s or our tin snips. 🤙
The irony is that the screw pattern you've used there is probably more intense, or at least equal to, most corrugated roofing I've seen installed in Japan - typhoon capital! If you saw the level of construction here you would not be surprised at the level of storm damage either... That Queensland pattern is hardcore! Every rib on the top and bottom, and every second in between? What purlin spacing is this based on? Also, wouldn't the screw depth affect this - like screwing a longer screw into 2x4 vs a shorter screw into 1x4? Actually a lot of the sheet metal roofing in Japan is just nailed on with capped screw shank nails... Good thing I can still watch Aussie DIY videos to learn how to do it right ;-) Cheers.
Caleb Fuller thanks for your feedback 🙂🤙
Can you tell me what size screws you use predominantly in this video? I've seen the term NEO and EPDM, are they the same thing? Also are they multi-grip screws?
The roofing screws in this video: 12 x 50 multi fix (multi grip)
NEO and EPDM - the rubber seal on the screws.

Good work.
I have a metal sheet roof in Thailand but they didn't fit sisalation.
I will have to unscrew the 3m sheets I dividually to fit the foil.
My house gets bloody hot.
Underneath tin roof. 55 degree
Ceiling temp 42 degrees
Room temp. 37 degrees.
Small windows and lack of a decent breeze doesn't help.
My house will be cooler when finished.
I know at least 25 degrees cooler under the foil.
Hi Glyn,
I would recommend using the insulation blanket with the foil. This will make a huge difference to the temperature inside the house. Best of luck,
Regards Darren 🤙😃
I need to do the same for my patio cover. In the meantime I've set up a sprinkler system on a timer just trickling and in 10 minutes it is cool as can be and I don't have to turn it off again. Just set it for as long as I want to be under the patio and it stays cool for a while. From this video and their barge capping video maybe I can try one day and put insulation as well.
Excellent guys
Ajith Rajapaksa thanks so much 😀
Great video. I have to put this on my workshop. Are the sides watertight as they are and what do you do on the top where you turned up the corrugation?
The sides are made water tight using a barge capping on the sides. This is the video: th-cam.com/video/v28-8Rwm0bE/w-d-xo.html
Hi mate, do you need to turn down the sheets for corrugated when they’re at a 5 degree pitch??
Hi Rod it would definitely help on a 5 degree pitch if you can turn down the ends slightly with your pliers 😀
Great video, very thorough and clear. Just wondering can you turn down the lower end of corrugated roof to avoid capillary action?
Thanks for the feedback. You can use pliers to turn down the lower part of the corrugated sheets. This will help, but corrugated does not work well on a flat roof compared to a profile like trimdek or klip lok and should not be used under 5 degree roof pitch.
Killing it Bois 🤙🤙🤙
Would have made about 5 bucks on that one. 🤣🤣🤣

I’m about to sheet my shed. In QLD and Widespan instructions say 5 screws apex and gutter purlins, 3 screws for mid purlins. I noticed you said every rib for apex and eve purlins, and every 2nd for mid purlins. Are they wrong?
Instructions are correct. But if you want to put extra in then ok, as long as you are ok with the look.
Random question, but when ordering your sheets do you order them from apex to fascia? That way when u position the sheet with 50mm over hang you end up with that 100mm ish gap between the two pitches at the apex on a gable roof ?
You could order from peak to facia because you can have a 50mm gap at the peak on each side of the hip, 100mm total, this allows for some venting.
Thanks legends!
sen a few roofing videos now why is the lining always sagging?
It give space for the foil to reflect back up.
If it was in contact, it would transfer the heat by conduction.
It should not be sagging! The under lay is for condensation, if the paper is not self supporting paper, they should be using netting under the paper.
When screwing in the sheets, how do you avoid hitting the nails/screws that join the battens and rafters?
Thanks for the message. This is difficult to avoid, when you find you hit a nail or screw you need to slightly angle the roofing screw.
Just how to use j hook in metal roofing
Screw the battens in top and bottom, knowing the roofing screw is going through the middle.
Also, i can understand the sag if your using woolbacked paper, but why do it for basic foil that can easily be installed flat and tight? Your feedback is much appreciated, cos everyone seems to do it slightly differently.
Hi Ceno. In regards to which way to run the foil. I was taught to run the foil down the roof length ways and have just always done it this way without any issues. If you were to to run the foil across the roof I suppose it would be a good idea only if the battens had been set up in the correct positions to support it at the joins. In regards to how much sag you should give it. Last time I researched this the-information I found said that you should let the foil sag down approximately 40mm between the battens for the correct air flow and less condensation. Personally I think that this is to much and can look pretty average, I only usually let it sag around 20mm. This would be a good question for the guys that make the foil. Hopefully one of these experts reads this and can help us both out with a more detailed answer
Coefficient of expansion/contraction is significant for Aluminium foil. If you lay it tight in the heat of the day it will contract at night and likely tear.@@metalroofing7210
Why do you use a drill gun to fix the screws? and not a impact driver?
Impact drivers are for bolts/nuts, not for screwing.
Why did you bend roof top ridge
its to stop the wind blowing the rain up under thus causing a leak.
Never back lap sheets
No way you look just like movie stars 😄
Get the staple hammer like the chippies. Soooooo much easier. Thanks me later.
Thanks for the tip. 🙂
What do Hollywood stars do when they are short on movie making, they go roofing!

Where's the anticon boys.
I'm starting to think that maybe Hugh is just a stage name, and his real name is Aiden.
Think you are onto him!
Sarking under a metal roof with 20mm overhang In the gutter, wtf, you doing massive commercial where the Insulation doesn't matter, if I sarked all my roofs I'd be broke, and my clients would be freezing
Tuck the wool behind the facia not Into the gutter, the Insulation acts as a vaccum so if it's in the gutter and gets wet, goodbye home interior
