TOPIC: I Have An Existing Metal Roof and Have A Question

Oil caning

Return to I Have An Existing Metal Roof and Have A Question

Return to Forum

Hi,
I have a question regarding oil caning the panels that are being installed on house have more like a rippling effect instead of oil caning and it’s only on the male side. Roof has 12/12 on sides and 10/12 front and back. I understand that oil canning is Common. But this panels have a rippling affect. Wondering if it can be a manufacture defect.

My feeling is this could be due to the roll former being out of adjustment or it could be what we call a "shape issue" with the metal that was run.

The panels were run on 2 separate roll formers and made sure the coils entering were lined up. Can this be caused by the trusses or decking not being leveled. On some areas it shows crowing on the trusses and uneven decking. C640FC60-94AD-4BDF-AD1B-1DD69EEA4177.jpeg

Well, then it does not sound like it's due to machine adjustment. If it was a metal shape issue, you'd have seen it in the coil -- lack of flatness along the one edge of the strip. I do see the unevenness in the roof deck in that last photo. Roof deck lack of flatness is the most common cause of oilcanning.
