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.

I'm putting new metal roofing on my tinyhome next week, weather depending, and this was extremely helpful.

This is by far one of the best installation videos I’ve seen on you tube . Thank you for sharing.

“It’s easy to get off, when you’re screwing”. Truer words were never spoke. 😂

This is an EXCELLENT tutorial video on installing a metal roof!! I just did the roof on my timber framed pavilion I built and the info in this video was instrumental in making sure my first metal roof install was super smooth. Thanks!!

Really helpful video. Thank you! Installing a metal roof on my workshop tomorrow, this has given me lots to think about.

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.

This is the most useful roofing video I've found. Thanks so much. Wish I'd seen this before I roofed the house 40 years ago.

House, barn and 4 out buildings with metal. This is an excellent video

One of the better videos on roofing.thank you.

What a great demo. I like how you went into the reason that you do or don't want to do certain things. Thanks!

I usually stack them on a sawhorse and pre drill them and it serves two purposes, keeps the screws straight and it is easier to start the screws

Well done Sir . Said with finesse & no fluff!

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

pretty good detail in your explanation. Red chalk always stains it's why i love it when im doing tile. I just bought a big fixer upper and i was going to try doing a metal roof for the first time it looks pretty easy ive done a ton of remodels and stuff and this was very helpful thank you. it's the small details that make the job better. Love it

Great content. I am currently building my first home with metal roofs. Great information and guidance. Thank you.

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

Awesome videos! Thank you for putting these together and for sharing your knowledge.

I enjoyed this. We put a new roof like this on the tractor shed. 24x80. Had it done in 3 hours. 3 people made it nice.

I remember many years ago as a young Iron Worker apprentice from time to time i'd get sent to work on Butler type metal buildings,what a royal pain in the ass,insulation different type screws. I remember the roofs caulking,insulation seam screws,drills i could care less if i never seen another one! But i remember the roof seam screws especially,was very easy to strip them and probably leaked at some point!

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.

Just wonderful. So helpful. Thanks!

Thank you for sharing your thoughts and intelligence on how too... Didn't realize there are multiple parts of videos. My apologies for thinking a head.

We just measure where the furring strips are and clamp like 10 sheets together at a time and just pre drill the holes through the sheets to get a straight screw line and easier starting the screw..just make sure to use a smaller or close to same size bit as the screws

Awesome video! Could you install metal roofing over battens that are attached to roofing rafters (no osb decking) if closed cell spray foam was applied underneath?

An excellent video with clear concise explanations. I am using metal panels to repair a barn door. Thanks

Great video with lots of practical advice.

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

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.

Last panel you didn't show,just what I needed.

I've pre-measured and pre-drilled the holes on the ground. Stack 5 or 6 sheets and pre drill them. Easy peezy. Worked like a charm. But I'm just here looking for pointers.

"It's easy to get off as you're screwing" Completely agree! Great video though, thanks

You answered so many questions that I had.................Many thanks.

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).

Thanks so much for these videos. I don't know when I'm going to get around to using the info., but at least I've got it now!

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?

I run foam strips along the eave's to keep water n ice out.About 3 inches up from the bottom.The panel dealer should have form-fit foam for whatever style panel used.

Excellent. Very useful and thoughtful. Thanks for the edification.

Excellent instructions. Thank you for posting.

Fantastic video! I am planning on having a metal roof installed on a gable roof at our home in northern Michigan. There, we get a lot of snow and I would like to have a roof that will not have to be replaced every 10 ~ 15 years like a asphalt roof. 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.

I took shingles off put down peel and stick underlayment, chalked lined my trusses to screw 2x4 wood strips to and put 1 1/2 Styrofoam insulation in between strips. I did the same screw lines as you for top and bottom but through the highrib everywhere else. Now I want to use self etching primer and cool coat silicone roof paint. Any suggestions on self etching primer on corrugated galvalume?

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

Interesting. What is the size of the boards that support the metal panels and can insulation go between shingles and metal?

Very informative, THANK YOU ! !

I got a little confused about the location of the last panel you installed; did you put the "panel you ripped to size "underneath the previous panel? or over the previous panel; I,m referring to the edge that was cut with the factory edge facing toward the end of the roof; the cut edge "OVER OR UNDER the PREVIOUS PANEL?? GOING LEFT TO RIGHT; VERY GOOD VIDEO LEARNING AS I GO; THANK YOU,PATRICK.P

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?

Love the videos have helped a lot I watch over and over

Yes. We do this often on outbuildings.

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

very well explained, thank you very much looking forward to more of your videos.

im thinking about installing this in a small over hang porch that is attached to my home is there any video you may have that shows how you would mount the roofing to the brick in order to make it water tight so that it would just run off the porch roof

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.

Helpful information and insights. Thank you!

great video! please tell a beginner if the short or long vertical edge goes on top or bottom.I'm sure it matters and have been told 2 different ways.

Great video.. 71 yo so I won't be doing the work myself.... BUT... my intention on watching this video to see how it is done properly and learn the "lingo"..si that i will know just how good a job the folks I hire are doing.

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?

Great video, for us old guys that are hard of hearing, if you could turn the music down just a bit would be great thanks

Would it be a good idea to install insulation between old roof and new metal. After framing it out. Is it possible to have a roof leak. Please watch this video. Again. May want to install some of this really nice roofing material. Even on the inside of... for like warehouses. Just a thought.

When you transcribed your end length to cut the final panel you did not cover how the angle will look or which end to cut. Because of your distance you will have a ridge so the obvious angle will be visible. Do you cover that, hide it?

Do not install the screws on the flat, only on the ribs. Water runs down the flat like a trough. You’ll end up having to replace the seals every few years. Roofing basics.

Thanks for sharing your guides 👍

I have done enough of these to do it wrong. As far as screwing the flats are best I've done it both ways and the ridges will leak. There is just too much movement in the tin with temp differents. After a couple years the screws on the ridge will leak. Flats minimize movement

I am running up the walls in my garage, how do i deal with the light switches etc.

Great videos! Very informative and comprehensive. Thanks!

what about a vapor barrier? i install titanium over top all my roofs over shingles. my understanding is that the heat from the shingles would cause sweating underneath the metal causing moisture and then eventually rotting the 2 by or furring strips? please explain..thanks

I like this video i have my first metal roof estimate to give this weekend exposed fastener over shingles just like this. I like everything but ill be putting down underlayment or bubble insulation before the furring straps for condensation purposes also will be using inside foam and outside faom for the eaves and ridge caps cant forget the butyl tape!

Thanks for making this video.

Great vid! Super helpful.

Great video. Thanks for doing it.

I have installed my 1x4 slats for a 20 inch on center. Some one came by who does metal roofing and told me I could skip a slat while screwing. That would put my screws about 40 inches apart. Is this distance to great?

Wish I could hire you. Professional!

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

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

i just installed a metal roof on a shed. i didn't put the fat end down first, the shed is just for firewood so nothing important to worry about. can you explain why the fat end goes down first? thanks - dana

Is that fiberglass insulation blowing around from the ceiling?

my roofing contractor has laid the sheets exactly opposite the way you recommend. i have a leakage problem. how do i get it rectified? Can you suggest something please

This is a good video. Thank you for sharing.

i need some advice as i am fitting velux roof windows to my build which has a metal roof but it has a pitch if 7.2 degrees so i am building a wooden box to elevate the window pitch to 15 degrees. i am uncertain of how i will be able to fully seal this wooden unit can you off any advice please i am at a loss at what to do to give it a full seal. i am based in the uk

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.

Does the paint on the washer allow leakage? Paint to paint I would think, would wick water between the paint.

Thanks for the video!

Hello there, how do the boys flash two 45 degree sheets on the ridge, keeping the standing seam or ridge profile or prickle along the top of the ridge please? I'm looking for a 12 inch ridge cap but must have no welding folded to 45 degrees for architectural appearance, rather than basic flat ridge cap. Thankyou.

Extremely helpful- thanks a lot.

This video is invaluable. What is the butyl tape for

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

Best video ever for metal roofing.if anyone knows of a better one please let me know

Great detailed video!

Would it not help to put Styrofoam boards in between the boards? Increased insulation to keep heat from penetrating into the attic. Would sweating/condensation make this a bad idea?

Very good demonstration Thx

my contractor is placing the other panels on the second flap. I'm seeing that it should be one narrow flap over the fat flap. We live where it's windy in the Caribbean where hurricane is a threat. Can a contractor here comment on what is best practice.

nice video if is okay to use plywood press instead of wood strips for vynil roof shet

How about the pipes coming through the roof?? How to measure for them which is more important than how to put screws in

what if my last panel rib lines up directly where my gable end or rake trim lands?

I’m thinking of installing metal ceiling in my garage. Was going to install the strapping on 16” center, or should I go to 24” center? The extra cost or work is not an issue I just want to make sure it looks good when finished!

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.

What's the wind rating on metal over wood? Would any county in Florida let you build a residential housewithout plywood or drywall? ... just metal skin over 2x4s framing , 2" Styrofoam insulation and MDF paneling on the inside?

thanks guy's - nice clear info , much appreciated!

Great video! do you recommend pilot holes with 5/32 bit to allow for expansion and contraction?

Awesome video

excellent videoes helped me alot
