For this initial enquiry, give the overall external frame width and the projection from the house wall to the outside front frame. Use millimetres.
These are enquiry dimensions only. Do not order or manufacture from this plan. Final dimensions, pitches and structural details need to be agreed with the roof team.
For a P-shape, T-shape or an unusual roof, include each return and the position of the house wall in your notes. You can attach a sketch to your email.
