At some point int eh near future though I am considering swapping the roof out for a better oine. Decent thickness planks first ( poss 30mm) with sterling board over it, then these overlapping felt tiles I saw tommy walsh using. I want the new roof to overlap about 1 to 1.5metres to the front for those rainy days.
Any ideas >???
"A" frames spaced at 16", or 12" if you're worried would be ok. 30mm would be scaffold plank thickness, which is what I used for my shed floor. Are you thinking of putting a second storey on it one day?
