Hi Nige, have you looked on here yet?

Planning Portal - Extensions

Logically speaking I cannot see why a 3 storey building requires an extension to have a flat roof. Surely in a fire that means a bigger fall if jumping from a window than it would on a pitched roof?

Most planning permission is fairly logical TBH so I doubt it needs a flat roof but that is purely logic and not fact...
