Workshop Roof Support

[Jugs69]

Hi,

Building a workshop/shed in garden. Have used concrete blocks to form walls and have now reached point where a roof needs to be considered!! I'm thinking a concrete lintel to span doorway? Overall width is 3.05m and door opening is 2.42m as I have 'rescued' a set of patio doors.
The lintel I've seen is 4in x 2in and 3m in length - do I just sit this on a bed of mortar each end and then run a course of house bricks along the top of the lintel in order to get a pitch to the rear? As the lintel is 3m and the width 3.05m will this matter?

I'd also appreciate advice on how to lay/hang the roof joists - was thinking of getting joist hangers but any other options would be welcome.

I have no building experience so any help would be appreciated Have a attached a pic of progress so far!

I think the concrete lintel you describe would be a 100 x 65, but no way would it span across 3m and support the back of the roof joists.
Just use a double roof joist as a beam over the gap and put joist hangers on for the roof joists.

Is this going to be a flat roof?

You could span the doorway with some double joists, but you would need to say what you are actually trying to achieve rather than just plonking a roof on.

Hi, its a flat roof with a small pitch from front to back. I have a velux to go in and other than that its purely to keep the space dry as i'll have some bike tools in there.
