If you need further info, here's a video about the 7 Common Problems of a Metal Roof: bit.ly/metal-roof-problems-video We discuss oil canning at the beginning of that episode. Also, here's a link to our blog article about oil canning as well: bit.ly/what-is-oil-canning Hope this helps! -Thad
Can I have a metal roof without seeing oil canning? I know metal stretches in heat, and shrinks in cold. Therein lies the problem. Can't get away from it. Am I correct???
Sorry having a trouble the understanding the gentleman at the top of the screen. Must be the audio feed. Too bad. When I can understand him. It sounds like he knows his trade.
Yes, sometimes the video call audio feed doesn't come through very clear. My apologies! We have some other great videos that feature Tom in person, and yes, he is extremely knowledgeable in the industry. Thanks for the comment! -Thad
At 2 minutes into this video, Tom says, "oil canning is just stress and then seal oil in them or copper or any kind of metal". That is word for word the text that is displayed as Tom speaks. There must be something lost in the captioning. It looked as if Tom was about to offer an explanation of how or why the word "oil" is related to the effect of oil canning. Also, will a flat finish (used to reduce oil-canning) result in dust or debris sticking to the roofing material more readily than would be the case with a glossy finish? Thanks, Tim
Hello Tim! Yes, that was a captions typo that we've corrected. Tom actually said, "Oil canning is just stress in the steel, or aluminum, or copper, or any kind of metal..." In regards to your question, the regular gloss finish is a little smoother than the low gloss. That being said, dust will slide off easier on the regular gloss, although probably not enough to notice. -Thad
When you attached the top panel to the deck you cause stress at the top. Likewise z closures attached at top to the decking does the same thing. Like how can the panel contract and expand if you are holding down either end of the panel? One soulution is have furring strips. This keeps the panel from heating up because of the ventilation underneath. Plus you are securing the z closures on the metal panel and not the decking. The panels should be able to float. Engineering makes it possible to keep the panels from flying off.
