discobob Posted August 30, 2023 Report Share Posted August 30, 2023 (edited) I have picked the wrong time of year to build a new shed. It is replacing a 17 year (at least) old shed and has a fixed base of 7'x7' and will be reusing that. I have built the framework for the walls and it will be a pent roof that is going onto it. I want to have an overhang of a foot or so at the front, 6 inches on one side and and less on the back - and the last side will be about 2 foot. My question is the way to run the wood. If I put the joists running from front to back, I will have to extend with ladders in the stud work for both sides, my thinking is that if I run from side to side, with the exception of a double stud on the back to extend that, I would only have to do a ladder to the front - or is there another reason why I would have to go back to front that I am not seeing? I need to be able to get onto the roof to be able to cut the conifers that belong to the neighbour and I am no bantum weighg Walls are built with 3x2 on 600mm centers and looking at 4x2 for the roof or would 3x2 on 600 centers be OK? @MODERATORS - Just realised it is in the wrong section - apologies... can you please move Edited August 30, 2023 by discobob Quote Link to comment Share on other sites More sharing options...
steve1066 Posted August 30, 2023 Report Share Posted August 30, 2023 Use 25mm thick plywood you then wouldn’t need so many bearers just one down the middle to minimise the bounce. Quote Link to comment Share on other sites More sharing options...
JKD Posted August 30, 2023 Report Share Posted August 30, 2023 If you're going to be climbing/walking on it, I'd use minimum 4x2's @ 400mm centres [preferably 5x2's] running front to back with the 'ladders' to the sides. 18mm ply for the sheeting, not OSB. I'd have used 4x2 for the front and rear, [3x2 for the sides is ok] also @ 400mm centres. 12mm ply to all internal faces for strength and rigidity, and for infinite fixing points 😉 Quote Link to comment Share on other sites More sharing options...

Front and back have double wall plates well screwed together for the roof to go on top of - I know the old shed could take a leg but it was as wobbly as anything and those studs are one inch and relying on the cladding to give it strength - I will be using 18mm OSB for the roof - black jacked up - as when I go on it I will put a scaffold board along the length to spread the weight - have you seen the price of plywood nowadays. 45 minutes ago, steve1066 said: Use 25mm thick plywood you then wouldn’t need so many bearers just one down the middle to minimise the bounce. again - the price of plywood nowadays is ridiculous!!! and two sheets would be needed I need to decide on if I go rubber or felt for the roofing (torch on heavy stuff....). I redone the old shed roof in lockdown as that was cheap felt that had cracked along the ridge and water had got in the OSB and used T&G and torch on felt - its a shame but the floor is going on this one - and it has been patched a number of times already....And building a shed is something I have wanted to do for a good few years now Quote Link to comment Share on other sites More sharing options...

It was indeed but unfortunately you need walls for a shed!! The Hikoki first fix nail gun has been in action this evening. I am making it as modular as possible. Walls have been done with screws and will bolt together, but the roof structure I am using ring shank nails for the 4by2 - but I need to order some more of that, ply for the floor and OSB3 T&G for the roof or if I can’t find that it will be ply as well. I have found some decent priced T&G cladding of decent thickness Quote Link to comment Share on other sites More sharing options...
