HOW TO INSTALL A METAL ROOF

In this video I will be showing you in detail how to install a metal roof on your shed, garage, or house. This style of metal roof is called a Pro Rib metal roof. Many people will also refer to it as a pole barn metal roof. We show and explain how to install eave metal, metal panels, screw layouts, closures, rake metal, and ridge vent

[@plankroofing]

I don’t want to be that guy that tells you all the things you did wrong, because that’s just isn’t nice and I’ve been on the receiving end of that myself. As a metal roofer, with years of experience, I would like to give you a few friendly suggestions. First of all 1x4’s are recommended to keep the metal off the shingles, so as to prevent it scratching the metal as it’s expands and contracts, and also allows it to breath underneath, and it also gives your screws solid wood to hold on to, if you only screw into plywood or OSB, your screws WILL back out and leak. And in our experience the closures you used will deteriorate and fall out, so I don’t like those, also screwing on the ribs is actually not a more leak proof way of screwing Down metal. I would also recommend doing underlayment, and obviously a shingle Tear-off is always best, but not necessarily required in all places. And just FYI metals from Menards seems to fade more quickly than some other manufacturers, but i understand not everyone has access to higher quality metal roofing materials. The one We like to use has a Valspar weather XL paint with a 40 year warranty. So another reason you shouldn’t cut metal with a grinder or a saw, is also because it heats up the paint and, ( with the metal we used) it voids the warranty. And I’ve personally seen where someone cut their metal with a saw, and put it under the ridge cap, and it still rusted. Not only that, but it also sends little hot shards of metal onto the panel and can also cause rusting where ever the sparks land. I’ve seen this first hand. All that to say, you have the basics down, and I’m sure your roof will last a good while, so good job on that, I hope this is constructive criticism, and not just another guy out here hating on your work, that isn’t going to be productive. And nobody likes to hear that. And I can appreciate the time you’ve put into this as I also make videos on Saw-milling and roofing, on different channels. @plankmiils Keep working hard and don’t stop learning.

[@paintasylum8315]

How do you recommend cutting metal roofing if not with a saw or cutter?

[@user-lb1bd8bc6z]

Metal hand snips or electric snips with the current cost per foot of tuff rib metal or any type painted roofing panels it's not a good idea to put panels on your roof voiding your warranty before you install the first screw

[@dllion3196]

I used a diablo fine tooth carbide blade on a circular saw. It will go through 5 sheets, leaving a smooth cut that does not need deburring to prevent cuts to your hands when handling the sheet. When someone told me this, I did not believe it until I tried it. Minimum heat and minimum sparks.

[@kenfarley957]

Your tips are helpful.

[@redsresearch]

1x4 will rot out

[@LindaM-kj8nh]

You are a great instructor. I can hardly believe that you installed this metal roof all by yourself plus videoing it. Great job.

[@JTP1967]

Been there, done that, and currently in the middle of doing one now. Hats off to you! It's hard enough when you have help. Keep up the good work. Thank you for sharing your tips. I've been doing this for over 25 years, but I enjoy watching other people. I pick up a lot of nifty ideas. Even though I've been doing this type of work a very long time, there is still opportunity to learn new things.

[@MrWorldasmaya]

Constructive criticism: a1) Modern metal roof science - it's no longer recommended to screw into the rib nor lap rib. The screw has greater opportunity to work its way loose based on contraction/expansion of the metal. The screws are placed on the flats as specified, by the manufacture, x distance from the rib. a2) If someone decides to screw into the ribs a special screw called a stitch screw is to be used & not the ones you used to do so. b) Don't pre-drill (even though it is easier). all metal screws are self-starting and designed to create their own penetration. c) Under the ridge cap the metal gets screwed down 'in the flats' to secure the panel itself. Depending on the desired wind-rating/code requirements those screws need to go in in addition to the stitch screws that secure the ridge cap to the metal sheets at the ribs. d) For people watching - never use an impact tool without a clutch to install the screws. You'll get what is called 'oil canning' where small 'dents' can be seen quite easily from the ground & 'oil canning' almost always means the washer seal is too tight. e) the overlap does matter and the warranty will be void if you install them in the wrong order (per the manufacturer) f) using a cut-off wheel will also void the warranty because the paint is more likely to fail at those points. Use a 'nibbler' or make the cuts by hand (and yes the manufacturer can tell what causes paint failures). From the comments it's pretty clear that people found this helpful and are inspired to do their own or go with metal in the future and I think that's great. While it can get expensive to have someone else do metal installs - If one is doing it themselves it's not that much more and it'll last for decades if done properly. 40 years is not an unreasonable expectation.

[@davidbadion7917]

Pre-cutting and pre-drilling the panels is a great idea and time saver. A better way to terminate the ridge end of the gable flashing is to run one side long and then cut the vertical at the ridge line and fold it over. Over all a great video for us DYI'ers. thanks for the tips.

[@stoneylawson1727]

I love the metal roofing, especially when leaving the old shingles under it for insulation, but in Texas I've noticed everyone ( or around where I live ) they put a one by up to give it some air flow underneath tbe tin.

Placing the metal directly on the shingles will inevitably scratch the metal and cause it to fail prematurely. See other comments above.

Rather than just start at the back, start at the end furthest away from the prevailing weather, the wind blows over the joint rather than under. Just finished an insulated box profile roof, not only does the insulation make it warmer but stops the frost underneath soaking everything inside when the sun comes out, didn't bother on my shed and as it thaws it "rains" on me, anyone with a van with no headliner will know the experience 😊.

Thank you for the informative video

[@randallcrawf]

Awesome information, i will be doing a steel roof for a shed. Was trying to get information for the PRO RIB at Menards. The roof is almost flat, 12 inch slope per 14 feet. For rafters I used 2x6 green treated sandwich galvanized steel. Roof 3/4 inch plywood. Most put the screw on the flat. I was under the impression that the screws should be installed on the rib. Glad i saw your video

[@Lifes_Apprentice]

Put the screws in the rib...You will thank me in 15 years when the ones in the flat are all leaking. I do not care what others say, put it in the rib. Be very careful with screw pressure. do not over tighten

[@johnlee7085]

You might want to check on the minimum slope for metal roofs. I think less than 3:12 is considered a flat roof and not recommended for shingles or metal panels.

[@johnlee7085]

@Life - Do you care what the manufacturer says?

[@randallcrawf]

@@johnlee7085 yes, very flat roof, will use tar paper and steel roofing. Heat tape for snow accumulated. Rain will drain. The slope is what it is. Will use boards to hold away from plywood

[@johnlee7085]

@Randall. Rain should drain if everything is perfect though nothing is ever perfect. Tar paper won’t give much protection on a roof that flat either. Any moisture that gets under the metal will likely wick up between the sheets of paper. You might consider a self-adhering layer to give some chance of sealing. Unless you already have the materials, you might also consider just silicone coating the roof.

[@dannyreed1632]

A circular saw with a metal blade or fine tooth blade will cut through the panels much faster and cleaner. Just my 2 cents

[@pmcdonald7871]

Great Job

[@JuanLopez-sx1er]

Marvelous Video God Bless 🙏

[@Lifes_Apprentice]

Thanks!

[@mackcollins1618]

I enjoyed the video. If I might add a correction to help solve the excessive wear from the grinder blade. The cut should be made starting on the other side of the metal panel. The cut you made allowed the knife edge of the metal to cut into and remove material from the blade, causing excessive wear. Cut from the other direction ( with you standing in the same position cutting away from you instead of pulling toward your self. ) This removes the knife edge effect and gives a smooth edge instead.

[@KitesurfHatteras]

Interesting. Thanks.

[@johnlee7085]

Or you could get a proper metal roof cutting tool that doesn’t void the warranty and lead to premature failure.

[@featheramericangoodeagle]

Down South (NC) people have gone haywire with metal rooves. All colors can be seen, but I really like the shiny black, especially on the white painted/siding exterior because it looks old fashioned as well as the medium green colored metal which is very popular in my area.

The shingles were in good shape as far as I could tell. Not sure why this was done.

Maybe it was constantly leaking because the shingles were incorrectly installed? Not sure. No explanation given.

(NEVER).... I repeat.. (NEVER) put metal down upon bare shingles!! (ALWAYS) use a roll of reflectix.... Looks like bubble wrap insulation.. Put that down first with long staples, use foil tape to tape the seams with a squeegee, then place the metal on top of said reflectix... Any "NATURAL OCCURRING MOISTURE" that can get between shingles and metal will rust out metal, this is where the reflextix wrap takes into action by protecting bottom of metal... It also will lower temps and reflect summer heat.. It lowered mine by 50% in summer upstairs!

[@dgmenace73]

Nice video. I read a lot of the comments and think you did it in a very economical way. I have never put a metal roof on and have a question. My garage is a 5/12 (I think) metal roof and has a leaking very narrow ridge cover. It's no more than a 6" ridge. I want to cover the existing ridge with a 12 to 14" ridge cover/cap. Is it ok to put a wider ridge over a narrow one? The only places my garage leaks is at the ridge and has an extreme amount of tar & kool seal on it already. Because its too narrow is why I think its leaking. Hopefully I described my issue to where you can help. Thanks in advance.

[@Lifes_Apprentice]

[@user-ol4uf6uu3u]

I seen in some of the comments before they told you it was recommended to put metal on 1 by 4 over the top of shingles I don't know who it's recommended by but I don't think they're professional at least not from where I'm from. It's recommended to tear all the shingles off come down to the sheathing make sure all nails are nailed down the sheeting is now down good if not renail it. Then put a good moisture barrier on it then screw your roof directly down to the decking and know if you get your screws all the way through the sheeting no matter if it's OSB or 1/10 they will not back out you have to come back in 5 or 10 years and replace the screws because the washers will be deteriorated but no they will not back out

[@Lifes_Apprentice]

That is why I screw in the highs of the panels because it will not leak when washers wear out...You should tear the roof off before install but this is just a shed and I wasnt worried about it

[@johnlee7085]

@user-ol4uf6uu3u What you described is best, though some add the 1x4 to create an extra air gap for ventilation. The 1x4 if the shingles aren’t removed is to separate it from the shingles and keep it from getting scratched, which leads to premature failure. It’s less critical in the scenario you described.

[@wolverineds]

Carry a portable table saw and put a metal/vinyl blade on it. Straighter cuts on your metal. Also, match the paint to your metal roof to paint the underside.

[@homesteadofhope9289]

Will be doing this for the first time in a couple weeks

[@Lifes_Apprentice]

[@Pete4875]

Great video! I am doing my shed now. I had my main house roof done. And he did not use the foam enclosures at the end. Should I fill them up with foam or something. Is it necessary.

[@Lifes_Apprentice]

You can add the closures after the fact.

[@getrail3d994]

Thank you for making such an informative video! Quick question though: Why does everyone put the smaller lap over the larger lap when installing the panels, and not vice versa? It's a much more flush fit with large over small. I guess it runs the risk of capillary action wicking water in between?

[@Lifes_Apprentice]

I don't think it really matters either way. just my opinion

[@asm101]

The reason you put the small one on top is to prevent water from syphoning up the rib. It also provides structure for the lap to maintain its shape while your pushing and screwing

[@NCJ0N]

It's recommended this way from the manufacturer. The other way around will wick water into the crevice.

[@leighwhite9656]

If you installed that around here it would blow off, you should always strap the roof with 1/4 spruce before installing the metal panels

[@jopaul32]

Very informative... Thank you! I was watching a manufacture video who drove 2 screws per valley instead of 1 per peak... The peaks makes more sense for run off but does it matter? Also, Yours is the first without furring... Again, do they matter?

[@Lifes_Apprentice]

You should use furring, I mentioned that in the video. I think you should screw in the highs on the panel because the washers will wear out and leak in the lows. The manufacturer recomends the lows but I have seen way to many problems over the years doing that. It is really up to you

[@raymondjiii]

What is a good way to bend that ridge piece like you did for a lower pitch roof? I want to do the same but I'm afraid it's just going to get all dented in spots. Thanks!

[@bigerns9643]

Did you leave the ridge open at the rake? I'm doing same style roof and was thinking about bending the metal in, but that seems like a pain. If left open, did you use any type of blocker to stop wasps, etc?

[@Lifes_Apprentice]

I showed in the video how I used foam closures to seal off where ridge meets panel and how I finished ridge where it meets rake...

[@clarencefoster7689]

Another add when strapping use vertical first then horizontal so sweating can run down and out the bottom not trapped behind the horizontal
