I think it's unfair to make generalizations about any roofing system when there is such a large spectrum of materials and installation practices. You're comparing DIY or handy man practices of corrugated roofing to higher end standing seam roofing. Take for example his statement that exposed fasteners back out over time and require maintenance. The first problem with that generalization is it has less to do with the system and more to do with the pull out value of the screw in relation to the substrate. The same screw driven into OSB has about half the pull out value as it does when driven into plywood of the same thickness. The second problem with that generalization is there is a large spectrum of installation practices. Screws installed through the rib into an OSB substrate will most definitely back out. Screws driven through the flat into a solid purling or fur strip will not back out. Lastly not all fasteners are created equal. Some fasteners have just the neoprene gasket situated under a hex head, others utilize a floating steel washers to compress the gasket, and higher end fasteners have an enclosed gasket within a solid hex head. I could say a great deal more. I do agree with much of what was said however I think your bias towards standing seam is apparent.
Robert, thanks for the honest insight. There is a wide variety of installation practices as you said, and while we try to cover as many as possible, we may miss some or not always be as clear as we might like. The topics we talk about are based on examples seen over many collective years of dealing with metal roofing. In response to your comment and other comments on this video, we've got an update video in the works that features more graphical content, and we'll also take into account other installation practices and materials. I appreciate the feedback and support Robert! -Thad
I was told metal roofing can be attached directly to plywood or OSB board after underlayment is installed. To be clear- underlayment is installed over the plywood or OSB board, the metal roofing is installed over the underlayment. Furing strips is a good choice if you will be installing metal roofing over your current asphalt shingles. Do a metal roofing google search for more info on the subject. I am not an expert, I just chimed in because no one answered your question.
1weird Doe The air gap increases energy efficiency up to 18%. It allows me to attach 1x4’s to the rafter not the weak osb boards. Then the connection from the metal to the 1x4 is always hitting good wood. Plus I can level roof as I go making the final finish better looking.

Sorry you didn't find it helpful! This series is more of an open forum/discussion to talk through different points of view. I will definitely consider producing a more illustrated version of this video, as I consider it a pretty important topic. Thanks for the feedback, Peter! -Thad
When you have a good thumbnail, but you don’t show good details in the video, while you talk, we skip the video. I don’t want to listen to a pod-cast. Show us what you’re talking about.
That's why I redid this video almost a year ago. Check out the new one with photos and graphics here: bit.ly/EF-vs-SSMR-revisited Thanks for commenting! -Thad

If you’re in Florida exposed fasteners are the way to go, they have a much high wind rating.
you can get the same high wind ratings with either system, it's all dependent on how you want to install and the substrate.
And check with your insurance my understanding is they must be exposed
Best location to place the fasteners on a exposed metal roof? I live in Canada so the roof will be subjected to heat and cold extremes. Thanks

I didn’t come here to look at four roof experts. Where are images of the roofs?
Right here: czcams.com/video/jlJpVabNAQY/video.html We released a new version of this video with more photos and graphics. Hope it helps! -Thad
Standing seam 6x price used more in commercial applications!
Can I go straight down to the underlayment with exposed fastener? Do you not need fur strips?

Guys, you need to explain which system your talking about when you go on a long explanation.

Some illustrations would have been maybe more useful than talking about it
We'll keep that in mind Matt! Thanks for the comment! -Thad
More illustrations coming right up! Here's the update video: bit.ly/ef-vs-ss-revisited
Thanks for the suggestion, Matt! -Thad
don't bother to show pictures or anything like this, this video is terrible
