a friend has a semi detached house built with a flat roof and parapet.
from memory, there is a pitched attic roof covering aprox 1/2 the area, with a door to get access to the roof.
It leaks and needs replacing. AFAIK it's asphalt
what's the best flat roofing material for this situation?
Glass fibre?
if he wanted to add external insulation is this doable with the door accessing the roof?
a building at work 20 years ago was re roofed and they seemed to add 4-6" of cork based material. would it be a celotex type material followed by the membrane?
