just wondered what sort of slope to put on a flat roof over new kitchen/living room and how to achieve this (assuming here that you cut say 3x2 down so that one end is higher than the other, then fix this to the roofing joists).
Whats the correct way of doing this please.
Also need some info on the type of insulation to use (is it best to use the ply sheets that have insulation attached to them)?
i know there are bound to be a few threads that ask why not make it a pitched roof - thing is it fits in with the design we want to achieve plus at 4m wide, a pitched roof would be far too high to get above a 14 degree slope.
suggestions please
