Happy new year!
I will be building a lean to roof against my existing brick built garage. it will be used as a wood shed so will have three open sides with the roof being supported by posts. The roof will be tiled to match in with the house and garage. The shed will be 3.0m wide by 3.6m long, so the rafters will be spanning the 3.6m length. Roof will be 15 degree. Couple of questions, was thinking of using a 200x100 timber lintel sat on the two timber posts (200x200) which will give a clear span of about 2.6m for the rafters to sit on. Will this suffice? I think ill probably need a purlin but this too will be mounted on posts and due to restrictions on the ground will be about 1.0m back from the lintel, giving a max span on the rafters of 2.8m. Will a 200x75 purlin suffice for this? Rafters will 150x50 spaced at 600mm.
Any advice much appreciated.
Thanks
Adam
