Roof materials

[winchboy]

the workshop is a grade 2* listed building, planning would like to see stone tiles back on the roof but may also accept a slate that is similar to that of the conservation area. At £12,000 and 20 ton for the stone tiles, as opposed to to around £6,000 and 10 ton for 22x11 slates it’s a no brainier.
the question is to fit welsh tonne slates instead of 22x11. Has anyone any experience with tonne slates, good or bad difficult to lay? Think the tonne slates would make the building more interesting as they seem to have been more common on commercial premises than residential, there’s a few lying round so do wonder if they were on the roof before the Marley’s were put on. Thanks

22x11 all day...ton slates are graded and fitted using diminishing courses (get smaller as you work up the slope) a lot more time fitting and a lot more wastage as they need to be the same thickness too on each course. plus unless your timbers are 1st class then why impact the roof with all that weight of ton slate

Well I know nothing about fitting slates but it is a fascinating subject. Never heard of ton or tonne slates. Is that the weight or something?

Found a very interesting thing online

Id find a good architect that deals with listed stuff.

He or she will be able to help on the planning side and will likely have contacts

you buy stone slates in tonnage and can cost a nice packet as well

getting hold of reused stone slates is an option as some or many remove them due to cost this point can be your saving but transport costs come into it compared to delivery costs from a yard
