Ventilating a Metal Shed?

[CarbonCrew]

I've got a metal shed that's approximately 12x20. I think it's a Lark. It's constructed exactly the same as the shed pictured below. Corrugated roof and siding on the sides with no osb.

The problem is that it get blazing hot inside down here in SC. I'd really like to add some sort of vent to the roof. Preferably a ridge vent or maybe a turbine vent. The issue im having with this plan is trying to figure out how to seal the roof against the corrugation. The lack of ridge cap makes this difficult as well.

Any suggestions or anything else I should consider?

Thanks

If it were me I'd leave the roof alone and start by putting vents up top in the gable ends. I just looked at some at HD yesterday that are probably 5" x 10" , metal, louvered, and already have the screen attached to the back. They were like $3.00. Cut the opening, goop them up with Your preferred sealant and rivet them on.

I would see if this helps before penetrating the roof.

You also need some insulation under that tin. Will make a huge difference.
