The Housing Standards 1963, now Supplement No. 5 to the National Building Code of Canada, require that hip and valley rafters be 2 in. deeper that the corresponding common rafters and that, in addition, ridge support be provided in the hip or valley section where a tie cannot be made between opposite rafter ends. Calculations were made to check the adequacy of this requirement.Peer reviewed: NoNRC publication: Ye
