jimal1969 Posted July 10, 2022 Posted July 10, 2022 We’re putting the joists for the roof in next week. Roof lantern at the back is going to be substantial smaller so not a problem. The 3x1.5 lantern at the front shows 47x200 joists tripled up but the key says 4 of. My chippy is saying 4 is a problem as you can’t get hangers that big. I’m going to try and contact structural engineer next week but in the mean time can anyone offer any advice?
