What is the maximum width of a standing seam panel? My roof supplier says that he can only construct a panel to 20 inches max. He did not believe that there was a way to install a roof with wider panels due to the potential for buckling. I'm from Texas and believe that I have seen roofs with wider seams. We are buidling in a hot dry windy area. Should we just go with the 20 inches or could we go wider if we can find a supplier?
If the panels were wider, does that mean that the roof material would have to be a heavier gauge?
Could you reply to my email address?
Thanks.

Teresa,
Yes, as you go to wider panels, there is more chance for waviness in the metal and typically heavier gauge metal will be used to try to compensate. Additionally, the wider panels can be more prone to wind uplift and, again, heavier metal might be used to compensate.
Sometimes, especially with wider panels, strengthening ribs might be put in the metal to help.
A lot of standing seam panels are in the 12 – 18” wide range. There are 20” and even 24” panels. Wider than 24” typically would be a through-fastened “corrugated sheet” panel. There are some sheet metal shops which hand-form standing seam roofing often in these wider widths but expect waviness in the panels!
It sounds like maybe your contractor has a rollformer and makes his own panels? His machine may be limited to 20” panels.
I will say this, to my eye, wide panels need large buildings in order to look right. On most homes (unless they are very large), I prefer the look of panels no wider than 15”. That is just personal preference though.
All Best,
