    From an architectural and or a planning perspective is there a technical definition of a flat roof.

    Specifically, I was wondering if there was any particular angle of pitch above or below which a roof becomes defined as flat ?

    architecturally, that point is usually 10 degrees or under, as defined in BS 6229:2003

    planning wise, the roof covering usually is the determining factor, as slates / tiles cant be used under 15 degrees

    why is it an issue? the eaves restriction usually has a big factor on planning exemptions

    Thanks for that information - it is helpful.

    The issue arose recently with a household insurer that did not want to cover a flat roof. Most of them are alright with flat roofs but some are not.

    I was just curious to know, in technical terms, where the tipping point lay on the issue of whether or not a roof is flat.

    The insurer will definitely have that written down somewhere I their documentation.

    If you're installing one now and worried about same you could ring your insurer to ask.
