Too much condensation in shed

[monkeyplasm]

I have a 24' x 24' area (privacy) fenced on 3 sides that I converted into a shed/workshed this summer; to temporarily replace my burned down garage.

First, I closed the 4th side with privacy fence (& gate/door). Then I planted a couple posts in the middle and used 2x10's and 2x4's to create a roof grid with a very shallow slope end to end. Over this a laid some nice second-hand full length roofing tin and was happy to have an enclosed, dry shed with lots of storage space.

Unfortunately, with the change in the weather, I now get A LOT (did I say A LOT?) of condensation on the underside of the tin roof, which drips all over and soaks everything in the shed.

Dang, it might as well be raining in there!

What to do?

Take the tin off, lay some plywood (or perhaps luan?) and replace the tin? Won't this still condense under the tin and soak the wood? Maybe lay plywood, then plastic of some kind, then put the tin back on?

I don't want to have to cover everything with tarps INSIDE the shed.

Any advice?

Thanks y'all.

Improve the airflow. If the temperature inside and outside is virtually identical, your problem should go away.

Or, pitch the roof more. So the condensation will run to the far end, instead of dripping off in the middle of the shed.

Pull the tin, then put down 1/2" plywood decking. Cover the plywood with tar paper, then put the tin back on.
