I'm monitoring the damp - and being a tin shed, it dries out and reduces the humidity very quickly once daylight is on it.
I cover the scope inside to stop it getting too warm.
The inside is lined on East and West with styrofoam.
The roof slides on the reinforced gable - it has no more gaps than the original design except maybe the end of the capping.
The roof comes together into a socketed hip so rain can't get around the baffle effect.
Here's a schematic of the hip I drew up, showing the construction
I have drilled through the reinforcing lintel on the side and threaded some rope through to the edge of the roof panel which when I pull on it draws the panel back up the gables, then I just clip the loose side of the hip to the side screwed onto the other panel .
Takes about a minute. The loose ropes are then tied off to secure the roof edge from lifting in wind
