    .

    We have got planning and have started to build a porch (its not subject to building control) - this also involves in having a roof spanning the garage (see attached pic)

    The span of the roof rafter is aout 1850mm @ 32.5degrees.


    here is the plan let me know if you think this is wrong.

    4b2 rafters

    4b2 wall plate in red (or should this be 6b2)
    4b4 wall plate in yellow

    does this sound about right to you?

    also here is other stuff i am looking to buy - let me know if i have missed anything.

    -bolts.
    -mortar to bed wall plate.
    -5metres of lead flashing (is non lead better).
    -Roofing lath
    -roofing tiles.
    -facia
    -guttering
    -felt.

    Undercloak?
    4x2 sounds small for the rafters but I'm happy to be corrected!
    (Can't see any pics)
