I have an old barn with an rusty corrugated roof. The rafters are pretty rotten and the corrugated sheets come apart and I have slow leaks. The roof is nailed and some of the nails have worked their way out.
My plan is to hammer the nails back in (where they still would work) and use rivets to rivet the sheets together on the seems to tide me over until I have time to repair the rafters.
I am wondering if that is a good idea and if rivets are actually water tight or how I can make them watertight and if there are special metal roofing rivets. Any better suggestions?
Easy to see where the sheets are lifted at the seams.

I know aluminum boat manufactures use rivets with rubber seals. I have not seen rivets used on corrugated roofing. I would convert the leakers to screws with washers that’s how most metal roofs are put on and if the wood is a little compromised at the leaky nail hole a screw will hold better than putting in another nail the seal on the screw makes it dry.
