OMG!! mate i have to say i do enjoy watching some work you do, however this project has you looking really bad these are the steps front wall plate needed a 2nd plate with packers to create the minimum 6 degrees for the panels to sit on front to back, then a barge board on each side the front is a monopitch flashing and the rear should have a drip edge thats under the roof panel never use foam under the panels to give sight all you do is make them all uneven and the room will become damp 100% guarantee water or the roof will become loose
