Definitely insulate the roof, but you might be surprised at how something cheap, like folded aluminium batt panels (from Bunnings) work very well. I was going to use 30mm foam panels but installed the folded (accordion style) panels first. They allow an air gap under the roof panels and prevent condensation buildup under the roof.
Also consider a small extraction fan and place it up high on your roof wall near the peak. I use a good PC case fan, runs off 12v, and if you connect it to a small solar panel it will start up automatically when the sun rises. There are also small solar powered fans on ebay designed for vertical mount but many are junk, with pathetic air flow and run at about 5v.
A door louvre vent, at the bottom of the door, can assist ventilation and give the fan a source of air to pull through.
I run a small remote wireless weather station in my obs, so I can keep an eye on internal temps and humidity in the obs from the house.
