We are having a block built double skin garden room built. Its under 30sq meters so doesn't require building regs. Carpenters have said they can vault the ceiling no problem when building the roof structure, i would like this but am a bit worried about roof spread as the tiles are the heavy concrete ones.
Any idea if we could / should be adding rafter ties? I was thinking something like the below and leaving them exposed which would give us an area in the middle that's fully vaulted but would still tie the walls together? Or do we need them both ways? Any advice would be welcome! Thanks
Building is 4.8m x 3m.
