    I'm not sure exactly what you mean but it's normal enough for a roof to be a bit off. I don't know how much off you're talking about here but you may start out straight and square with the sheets and keep going at like that until you cover the entire roof . You'll get away with pulling the sheets a little but not too much. It does add up though over an entire roof. Any overhang is trimmed flush. The flashing will tidy it up.
    What length is the roof and how much off square is it do you know?

    At the highest point of the roof its 7 mtrs wide and at the gutter is five mtrs wide.

    You're not gonna pull the sheets that much over an average sized roof.
    I think you may start out straight and run out the sheets untill you're left with a triangle. Run on the last 2 sheets as you're going along and trim them to fit. All your trimming will be on the last two sheets.
    That's how I'd go at it anyway. There could be a handler way that I don't know !

    Put on two flashings on the angled side. Put the first flashing on straight to the timbers then sheet over this. Top flashing then goes on as normal. All the water that runs down behind the top flashing will be brought out by the bottom one.
    Hope this makes sense!
