I have a flat tiled roof with slight run off to central point
I'm in the process of insulating the walls with xps extruded foam blocks covered with armoured neting and mortar.
I now want to extend the insulation project to include the roof.
I need the roof to be transitable, so I'm drawn away from using a combination of vapor barrier, xps foam and outer ashfalt barrier on top?
I recently heard about some spray on type of cement foam which both seals/insulates the roof and it is more transitable?
I would apprecaite some input/Advise/Options
