In this video, we install an Exposed Fastener metal roof on a rural home in Arkansas. Throughout this series, I highlight methods we have found to be useful after many years of installs. We follow our manufacturer's installation guidelines the best that we can. Hope this helps someone.

Water under the metal roof from wind blown or condensate will go down the felt under panels, get between the drip edge flashing and felt, get trapped and rot deck and fascia. That's why you are better to put felt OVER the drip edge flashing. In a perfect world, drip edge nailed to deck, bitumen flash tape over flashing/nails and deck...and felt over that. Then water running down deck even under the felt, will go over tape/flashing and out between flashing and felt and away from building materials. I know most folks just say, we've always done it this way and never had a problem....but these small details can make the difference between getting 10-20 years out of the metal roof, or as much as 50. Replacing deck and/or fascia areas due to water intrusion is major surgery, and usually avoidable.

An awesome trick I learned when you are starting the panels... Instead of measuring and snapping a line, I just tack the first panel on the left side on top or bottom but before placing the second screw, I place another panel and do the same thing and put one screw as close to the seam and the screw from the first panel as I can because this allows you to adjust both panels together while keeping the seam nice and tight from top to bottom. Just a quick glance down the drip edge and up the rake and it always works out beautifully without having to step the panels at the bottom or having to "stretch" the metal to straighten it up as you run your panels out... Just be sure to screw the whole seam off on those first two panels before you try screwing the outside edges at all so that you don't end up with any unwanted bubbles or a seam that sticks out like a soar thumb...Because in case you didn't notice already, the metal doesn't like to "stretch" very easily.... Not without being pretty noticeable from the ground anyway... It just works much better to screw the panels off from the seam and working outward from there.... Great video though taking the time to explain all of those little important details that are crucial to doing it the right way. Attention to detail makes all the difference in the world if you ask me... It separates the skilled carpenters from the fly-by-nighters...

I have tried your method. It was actually our standard for years before we switched to the method we're using now. Not sure what gauge metal your using, we use 29ga and it stretches just fine, I've never seen it cause an issue so we continue to do it. The chalk line method is the only way to roll IN MY OPINION. If the other works for you, keep doing it. We found much more consistent results using the method shown in the video.

Exposed fastener metal roofing is used on 95% of houses in the Philippines from low-end to high-end. This was really helpful especially in showing how you keep the sheets aligned straight at the bottom using chalkline and tick marks. As we are building our house the roofing team, a few months ago, had a hard time keeping things aligned as they did not have such a reliable method. I would have recommended your method to them.

One of the videos I watched had the installer placing the Screws on the ribs. He said his reason for this was that the water will roll off of the ribs, onto the flat portions of the panels. Thus, if there are a lot of holes on the flat portion, it would increase the likelihood of leaks. His reasoning made plenty of sense to me.

@miillersconstruction 8 ай бұрын

His method is not approved by my manufacturer and I have personally witnessed failures when installed this way. The fasteners don't have any structure to rely on, a good portion of the fastener is just floating inside that rib. When the metal expands and contracts, I have seen the fasteners snap, back out, and even rub the washer dry. If you look at the design of the fastener you can even see that it's incorrect. Try installing that screw on top of the rib of the panels we use, a good portion of the rubber gasket won't make contact with the rib. Many folks unfortunately think like he does and failures are the result. If I had not been behind guys like him fixing these failures, I might not have known any better either.

@mustangecoboosthpp3869 7 ай бұрын

Manufactures show installing the screws on the flats, one reason for that is the manufactures wind lift testing was done with the screws on the flats because that provides the best method of securing the panels to the roof deck. If you install the screws on the ridge then none of the wind lift data will be valid. Also as the post from millers construction stated is the screw is not as secure and it does not seal as well at the washer when it is installed on the rib.

I wish cameras showed things straight, watching the roof get screwed down it looked like everything is crooked. I used that same metal roofing this past summer, when you mention that plastic rap of the drip-edge and rake pieces, I almost had a melt down trying to get that stuff off!!!!!!! I placed screws 28"-ish on my 16' panels, roof is addition off my house, used transition panels to slide up under existing asphalt shingles. Addition is only 16'x30' and only goes down 1" in 14", so I used that sticky weather shield underlayment, it has some sort of thin blue fabric on top, so far the it's not leaking but winter isn't here yet. Also I left about 2" of my drip-edge exposed and use the the sticky foam pieces under the edge of roof panels, just so wind wont get up under there making wind noise, and or bats.........

@waltermatthewberg 2 ай бұрын

I'm guessing by how wrinkled the felt is they probably left a few nails and debris. They make us use ice shield where I live and run it at least two feet past the wall but it's really not necessary if the attic has enough insulation. That looks like standing seam eave trim for folding the edge over with no exposed fasters. A three inch or bigger face on the eave will have to be clipped in or face screwed or it might blow off in high wind. You want a big enough screw for the panels to penetrate through the metal and decking so the cone-shaped portion of screw is sticking through the bottom of decking. I use the 3-4-5 method to make a perfectly square line perpendicular to the eave with no sawtoothing. The screws are usually the first thing to leak so knowing how to drive a screw is probably the most important thing: push down hard when driving to sandwich the panel to the decking, if you suck up the metal then reverse until the threads push the metal back down and re tighten the screw, the washers want to be firm but not crushed, try to drive every screw perpendicular to the plane.

I like the chalk line, but why not use it for the drip edge, instead of eye-balling it? The reason for 1.5" long screws is because purlins should be used. There's not as much holding power going into plywood vs a 1x4 or 2x4 purlin. For the added cost vs benefits it's a no brainer.

I would suspect you would get flagged. Alot of people are really worried about all the exposed fasteners. The roof were working on right now was peppered with them and it was installed in 2006. The washers on the screws still look perfectly fine. Don't be worried about the amount of fasteners. The one thing I will tell you though, it's ok to space them greater than 24"on long sheets. We do it all the time regardless of warranty. It's just not necessary to have that many in it.

@@madman432000 some guys do it because it's code in their jurisdiction. We will do it occasionally if we're going over a shingle roof. Our metal manufacturer not only warranties the steel fastened directly to the deck, but they also give us step-by-step instructions on how to do so. Here's my thoughts on furring strips - The only time I've ever seen exposed Fastener metal roofing blown off of a house, was when it was attached to strips. The metal is ALWAYS still attached to the furring strips so what failed? The connection between the furring strips and the decking. I also don't like the thought of allowing additional airflow underneath the steel panels. If an abundance of air can move under the panels, during a high wind storm or tornado, You've got a lot more potential for that roof to be ripped off. I want my roofs tight to the deck. There is no advantage of installing furring strips in MOST circumstances. Sometimes you have to, there are various situations where it is required. We avoided if we can. We also don't have roofing failures ever when we installed directly to the deck.

My roofer took off the old shingles and felt , then put a new moisture barrier down and then furring strips down and screwed to those , because he said in the past 10 years installing metal straight to the one layer of shingles was over time causing the screws to back out a little because the roof has to have a small amount of play to slightly move as the metal heats up and cools . He also said he had seen video's of standing seam roofs being totally torn off in high winds because the entire panels are hooked to each other as where tuff ribbed panels with exposed fasteners were not . Any thoughts anyone ?

@miillersconstruction Жыл бұрын

I've got a lot of thoughts on that. Great comment. So I personally have not seen any indication that the panels would have an issue being fastened directly to the deck. Even the metal manufacturers will warranty and recommend that installation technique. I love the thought of air being able to move under the panels to dissipate heat if you're using furring strips like you mentioned. However I'm not a fan of air/wind movement under the panels in a storm like condition. If wind can pass underneath it, the panels can be ripped off. What he's saying about the standing seam panels makes sense, but it sounds like he's trying to sell you on exposed fastener. I'm also a huge fan of exposed fastener, but anyone who discredits the durability of standing seam either is ignorant or has an agenda. It sounds like the latter. Installed properly a standing seam will outlast ANY roof in a storm.

@miillersconstruction, The air gap and firring strips might not be needed for the manufacturer's warranty but it makes the installation look much better when you can eliminate any sags or humps and straighten out the imperfections when you fasten the furring strips down... It also allows you to tighten up any of the roof decking that has started to loosen up like it always does near the gutters and gable ends. But that air pocket that gets created really does add R-value between the warm house and the cold metal (& vice-versa).. Just like you're supposed to install baffles if you insulate the attic ceiling to vent the roof and prevent the shingles from getting burnt and falling apart in 10yrs. Plus the added R-value significantly reduces your heating and cooling expenses. The air pocket acts as the dampener between the two, reducing condensation and extending the life of your material... Especially the rubber gaskets which are usually the first thing that fails on a metal roof.
