No roof lasts for ever. A well designed 'flat' roof can have an acceptable
one.

It noticable that the local council has put pitched roofs on many of its
older blocks of flats around here... They look so much better too.
Flat roofs may be ok in e.g. Greece but not in northern europe.

I had no option with my attic room conversion since I wanted more usable
floor space than a pitched roof could provide. The important thing with a
felted flat roof is to make it so water doesn't lie. This requires skilled
design and construction. And of course then it's not really a flat
roof. ;-)
