i am building a shed, well rather a garage.
it is built out of 4" concrete solids
the size is 25'W x 16'D
i am wanting to put a flat roof on it so that i can stay under the 3Mtr height.
how many roof timbers will i need and at what spacings should i put them, i am covering the foof with 8' x 4' 18mm sheets
also, what pitch/slope should i put on the roof
thanks for any help you can give me with this
