Flat roofs now have to have IIRC a 1:50 slope, Suggest you measure the
slope, they made them *flat*
in the dim and distant past. If it is less
than 1:50 ish it may be better to go for a pitched roof.
I have re-felted a flat roof with cold bitumen and roofing felt, no great
problems, except for the mess.
