What pitch is not a 'Flat Roof'?

    Hi,

    I am planning a single storey extension to my 3 bed semi detached house. Due to the size and layout of the extension it would seem that a flat roof is the best solution. The typical pitched roofs or lean to's will impact on the second storey windows.

    I spoke with my insurance company and they said that if the flat roof constitutes less than 30% of the overall roof then it should not affect my premium. Between 30-50% will raise my premium and over 50% is unlikely to be covered.

    What pitch of roof is not considered to be flat? Is there a defined pitch in any guidelines? I know all flat roofs have a slight pitch for run off but at what degree can a roof no longer be defined as flat?

    Thanks,
    Kev

    Generally 10 degrees. Anything below = flat. Anything above = pitched.

    Great thanks. So I could potentially put a 12 degree pitch on the rear of the house and as far as insurance is concerned it can be considered pitched?

    I have heard that openable Velux windows should aim for a pitch of at least 18-20 degrees so would I be better with fixed skylights at a lower pitch?
