Looking for some help in working out materials required for a new roof. I could just get a roofer round for a quote, but I don't want to waste anyone's time as I will probably source the materials myself and then hire in some labour.
It is a pitched roof, 30 degree angle, each face of the roof is approx. 110 sq metres, ridge length is 18m. The slates will be 32cm x 22cm and secured using the hook method, not nails.
How many slates will I need? Also, what should the batten spacing be, and how much batten will I need and what size?
All this is a bit beyond an IT bod . . .
you won't be wasting anyones time, you'll be paying for the knowledge and experience that a roofer has to order the right amount of materials.but I don't want to waste anyone's time as I will probably source the materials myself

At this point I just need to know how to work out the approximate amount of materials that would be required. From that I can look at suppliers, either locally in France or possibly in the UK or Spain which can be cheaper and/or better quality, and work out the appxoimate cost.
Getting a local roofer in who would only look at local suppliers could be a waste of his time. Having said that it might turn out to be the best option in the end.
Pjm84 that's for interlocking tiles, no good

Chinese slates are cheaper still
Holyzeus - thanks for the link. The slate sizes are not quite the same, but I can take a view based on the numbers for sizes above and below.
Chinese slates are cheaper, but I've heard of a few quality issues. I had Spanish slates on the house roof, so will probably go for those again.
Doh! Looked at the Source website and attached the other link.
Yeah see size's are not quite there but it'll give you a good idea. You are using a very small slate
Chinese really aren't bad but if you can afford better then good.
Only did hook slating once, bout 20 years ago!
The size is a bit small, but that's the size used on the house and the barn looks to be about the same. I'm not sure what the implications would be of going up a size or two.
The French like the hook method, probably better in high winds, and apparently quicker to fit (although that is just what someone told me).
They are quick to lay
i like the hook method. as above chinese slate is sh1t. i won't go on them for repairs these days, fancy going up to fix a couple, only to have most of them around your cat ladder snap on the way up? no ta...
