Metal Roof seam issue

My metal roof is popping up on the panel overlap across a 15 foot vertical line. Each panel has a slight bubble showing the panel underneath. It isn't leaking but I am concerned that wind may catch it. Can I screw it down?

What type metal roof? There's dozens of different styles.
A picture is always great.

Welcome to the forums Ron!

More than likely you can screw it down providing there is some wood under it for the screw to attach to. You want to use roofing screws that have a 'rubber' washer which seals it from leaks.

Is there wood directly under that area? The way the roof is screwed/nailed it leads me to believe the roof has plywood under it. If there is, it's no biggie to screw it down but if it's a space between boards you'll either have to go up hill to the next board to screw it down or add lumber from the attic side. I like to squirt some caulking in the gap as I'm screwing it down to give it a better seal. Wind driven rain can be forced into those gaps.

this is the type of screw you want - Shop Teks 400-Count #12 x 1-in Zinc-Plated Roofing Screws with Neoprene Washers at Lowes.com

I've never seen 5v crimp nailedd in that manner. There must be a kazillion nails in it. They are properly placed on top of the ridge, but why so many, and what are the nails hitting? Is there a solid plywood base to this roof? That may be the answer. If so, do as Marksr said and use neoprene washered screws just to the left of the double crimp to pull it down to the plywood.

Today's steel roofing is screwed on the flat across slats, and not on the ridges as 5v and other types are, so techniques change over the years.

OK, Mark types faster than I do.

Screws

Locate the screws on the flat section of the sheet rather than on the ridge.

Screwing into the top of the Vee was not the correct way to attach it, and that's what's causing it to buckle.

Joe, the bottom example in your link shows the roofing being secured on the top of the V ridge. Back when nails were commonly used on metal roofs that was the correct placement..... but I've never seen as many nails used like they did on Ron's roof. You always wanted the nails on the top of the V so that when they worked loose, it was less likely to cause a leak.
