Nick Trollope Posted January 24, 2006 Share Posted January 24, 2006 Hi allCan anyone point me in the direction of some information on basic pitch roof design. Basic info only, such as the spacing between the common rafters and the relationship between the batten spacing and the tile size.TIA! Link to comment Share on other sites More sharing options...
Deimos Posted January 24, 2006 Share Posted January 24, 2006 I could give you some examples by going and measuring mine(if that would help). However, they areall old and mostly oak. I believe thatthe tile sizes generally available these days are slightly larger.I need to build a small roof and got the roofer round theother day to advise (its great as he has loads of work and does not seem tomind telling me how to do stuff – and I don’t “take the p**s” as there is alsoloads of work I need him to do). Hedrew up a plan for me (timber sizes and “shopping list” but there are a fewimportant measurements missing (e.g. spacing between liteau). When he next visits I’ll need to get this(and other) info from him.Let me know if you want me to measure anything and if sowhat.Ian Link to comment Share on other sites More sharing options...
adrianpmills Posted January 25, 2006 Share Posted January 25, 2006 We bought our materials from the local builder's merchants. They were happy to advise on all that, plus french regs. Also, they had fact sheets for each range of tiles which carried very detailed info, with pictures, on how to do your roof. Link to comment Share on other sites More sharing options...
jonboy Posted June 2, 2006 Share Posted June 2, 2006 Hi Nick, the centre of the rafters should be no more than 600 mm apart, but this could be less depending on the dimentions of the rafter. The gap between the battens totally depends on type and size of material being used Link to comment Share on other sites More sharing options...
Michael Posted June 2, 2006 Share Posted June 2, 2006 Nick.Not wishing to get in an arguement with the pros!!, on your tape, metric or inches at 400 or 16inches there will be a black dot or triangle or diamond that is for standard joist centres.Battening centres depends on your tile type.

sharkhunter Posted June 2, 2006 Share Posted June 2, 2006 Hi, basic dimensions are 400 centres or 16", this applies to UK style pre stressed trussed roofs, i'm sure the same applies here in La Belle France. Traditional roofs that are cut to create pitch and use a ridge are of greater dimensions, and can be further apart than trusses. These are the normal type of roofs here in France, in my experience, but due to the irregular size, shape and design they are spaced out differently and very difficult to recreate, not for the novice to handle. My advice for a self build is to source a truss manufacturer and get them made to measure, as for the tiles they are mechanical and as such have regular sizes and spacing that is readily available from most tile stockists, hope this helps, Hugh.

zeb Posted June 3, 2006 Share Posted June 3, 2006 Nick - sorry I haven't had time to look, but I think there is some "how to" info on the Leroy Merlin website. Link to comment Share on other sites More sharing options...
Nick Trollope Posted June 3, 2006 Author Share Posted June 3, 2006 Thanks everyone for all the info, but I completed the roof (as a novice), a couple of months ago - look at the date of my first posting. Designed it from first principals with the assistance of common sense!Thanks again. Link to comment Share on other sites More sharing options...
