    Roof partial overhang

    Hello people,

    I have a question about a roof of a shed. (See attachement).

    The shed has an existing part, and a part which is new to build.
    Now i want that the ridge of the new and de old roof is at the same place, but the overhang from the new part has to be longer.

    If you will look at the pictures i add you'll probably understand.

    So the roof in the back is drawn good, with that overhang.

    But if you see the 2nd picture: The left part of that roof has to allign with the front part.

    I want to have one big roof, but the part left in the back has to have a bigger overhang than the rest of the roof

    I hope you people understand my question,


    Thanks for your help already!

    You'll have to lower your eave height at the wall that sticks out past the other one. The height of that eave depends on the pitch of the roof and the offset of the wall.

    so, for example, if it's a 4:12 pitch and the wall is offset 2', lower that eave (sketch line) by 8".

    or, you can use slope arrows (as per pic.) with the slope to match existing roof.

    Simple way:-
    Roof by footprint / Extend into wall (to Core) + overhang.
    Just define the two walls of the short span and Revit will do the rest.
    If you want to opposite effect (cutoff span) just define the two walls of the big span.(image 4-5)

    For single roof yes, but I think, the OP wants new roof to be attached to existing.

    Two single roof's just as easy,
    roof by footprint / extend into wall (checked) add wall return onto overhang but select shorter span wall (see image)
    or use slope arrows, (I try to avoid them personally)
