Hi all,
I have recently completed a block built summerhouse/workshop in the garden. My intention is to have a flat roof with a slight overhang at the front edge.
The building size is approx 6.5m wide by 4.5m front to back.
My question revolves around the correct joist size for the roof. As far as i can see there is no readily available timber size suitable for what will probably end up being a 5.5/6m overall length. I have looked at ‘sistering’ 152 x 47 with something like a 600mm overlap and bolted using toothed washers, but can’t seem to find any advice on whether this is acceptable?
Should probably mention the building is nearing its height limit so anything that could be done to keep the height of the roof down would be appreciated. Thanks Darren
