Got a 4m x 3m space over an extension thinking about putting a terrace on it, cold roof.
Was thinking zinc is a good long term option as it will have a deck on it, but the min fall is 3degs apparently meaning it would be a lot higher than other options. I don't know if there are other options like having taller seams for a 2deg fall?
Lead is 1.8 I believe, and GRP even less.
Whats the best option?
I saw a large GRP roof being laid, looked easy but don't think it will do well with a deck on top.
Torch on roof is okay but will need 20yr replacement cycles I imagine.
Lead looks like it would be 2" strips with wooden rolls between them, quite a lot of work and a lot of seams.
Any advice ?
Cheers
