Replacement garage roof

[john59]

The guy next door is giving me his concrete sectional garage but the roof will need changing and at the moment the roof is supported by simple angle iron and I need to change these to timber joists so I can create a proper roof viod to insulate and run cables through. Hs anyone got any suggestions how I will fasten the new timber joist to the concrete walls of the garage ?.
Many thanks in advance for information.
Regards.
John.

Has anyone got any suggestions how I will fasten the new timber joist to the concrete walls of the garage ?.

Done quite few of them and they not all the same but it all can be done. Most of the one I've done has a hole in the centre of the precast slab for 3"x2" wallplate bolted to it for the roof rafters. The other one I've done was a garage like a section of gravel board slided into post and that has a 1 1/2" angle iron on top which I use for the wallplate to screw into. I don't know the what type of garage you have but I can help you more if you could do a photo.
Pitch roof on garages should be no more than 4m high for building regulations. I find it cheaper and quicker to have the roof section made by roof trusses company which make the roof frame section with nail plate, you just give them the span measurement from wallplate to wallplate on the external. I saved over £700 on my extension instead of making it the traditional roof method.
I can't give you advice for what type of electric cables etc.
