I used to screw them on the rib, but I think screwing in the flat area should be better for a couple of reasons: better fastening to the wood bellow and allowing better dilation and contraction due to temperature. Although water affects the washer over time, it should be no problem for at least 10-15 years. So, use good quality fasteners and the proper length. This is more important.
An iron roof today will last more the 60 years and some will last 100 years. You should always fix the the crest of the roofing sheets then you will no maintenance problems other than painting. If you fix in the bottom you will eventually have leaks. Here in Australia hey are always fixed to the crest. I am a retired roofer, i have been putting iron roofs on for 30 years.
@@johnbarber107 You're a funny guy. Iron roof??? We're talking about screwing through steel. Screw through the flat part for the best performance, i.e. wind uplift and water leakage.
Thank you for reaching out! They key to longevity is in the washer, the material and the threads. For example, our ZXL MB WoodBinder screws are cupped with a molded ZAMAC Zinc-Aluminum alloy that provides a lifetime protection against red rust on the head and washer. The threads transition from a fine to coarse to generate holding strength in to the wood. The micro-bit point also reduces metal shavings that can embed in the rubber washer. What it really comes down to is the quality of the fastener and installation. If you have more questions on this, one of our Product Specialists would be happy to talk through your project with you. We are here Monday - Friday 7:00 am - 5:00 pm CST. Give us a call at (888) 794-1590.
@@robertbutler8004It doesn’t matter if the metal roofing is screwed fast to wood or steel because expansion and contraction of the metal roofing panels eventually pull the screws. So what if the metal panel lasts 50 years when it starts leaking water in 10-15 years due to the roof, expanding and contracting. The only metal roof that should be used on homes is standing seam.

Lol if ya got a clue ya wont screw in the ribs lol . What do you think happens if any kind of compression happens on that rib ? 🤔 perhaps you loose your seal ? If its in the flat this isnt a possibility. I get how you could think the rib would be a good option though.
What about all the debris from the screw drilling the hole. You need to work on that problem before you worry about all this other nonsense. It is painfully obvious that the engineers at this company have never done 2 things 1) done this type of work 2) watched the video I saw the flaw @ 1:50 then 1/2 dozen more times throughout the video.
Thank you for pointing that out. I will pass this along to our media team to check this content and have our Quality Team review as well. It is very important to us that we are providing useful quality content. Thank you again for sharing!
Amarshallcollins8634 agreed at about 1:50 the swarf was left under the rubber washer here in Australia we screw through the ribs and the swarf is inclined to fall onto the flat and then blown off with a leaf blower.
@@robertbutler8004 You can also wash the roof down with water. I have worked in Darwin and the roof is hosed down at the end of each day. this will get rid of the swarf.
Thanks for reaching out and sharing your thoughts. There is certainly varying opinions on this topic. It seems installers have a preference based on what has worked best for them. We did ask this question from Manufacturers on what they recommend. Their recommendation was the flat part because it offers a solid wood surface below the panel, resulting in a tighter more secure seal. We have read several great articles from installers who are trusted experts in their field that say otherwise too. Thanks again for sharing, we always appreciate the feedback!

How do you keep the screws into wood sheets from backing out over time?
@fn6553 here in Australia they never back out.

@fn6553 when fools fix metal roof sheeting to ply sheeting it is not a matter off time if they back out it is a matter of time when they back out.

What about on a steel Z purlin? on the flat or the ridge of the roof panel?

Appears to be THOUSANDS of fools out there doing this work
