Outhouse shed roofs

Hi I have a 1940’s old terrace house, put the back are 2 old coal and toilet sheds. They have reinforced concrete roofs, there are steps up and was previously covered in decking. They started to leak so I removed decking and looks like old torch on felt underneath that’s disintegrated. I want to continue to use this area and maybe lay some artificial grass on top what would be the best option. I’ve had recommendations for a grp roof, some say 11mm osb on top and some say 18mm osb to stop movement and cracking the grp. Considering it will be fixed to a solid concrete base will 11mm suffice?

Flat roof advice

Hi. I have managed to now get the joists on fixed to the timber wall plate but not every joist is bang on level either due to natural defects in the timber or the wall plate not sitting 100% level due to me not having all the tools available and first time trying a diy flat roof. Will this cause me untold problems later down the line or can I make sure the firing strips are fitted with packers where recess before installing the osb? I’m wondering how much more money I waste before I give in and pass to an expert?
