Most products are rigid or textured enough that they will not. By all means, though, inquire with the roofing manufacturer for their opinion. Todd Miller

If the decking is uneven, meaning that uneven pressures are exerted on the panels when they are installed, yes, it can force ripples into the panels. Todd Miller
