Prior to our involvement the homeowner was faced with costly roof replacement to remove and replace the sagging rafters. The project created a dynamic open ceiling affect for a game room while preserving the original roof material and exterior appearance. It completely eliminated the unsightly roof rafter sag, while adding substantial additional capacity for future re-roof.
The project was a conversion from conventional roof construction built in 1957 to a contemporary vaulted ceiling, with exposed trusses. In this design the original roof rafters were used as the top chord of the trusses and the exposed steel pieces were used as the webs and bottom chords. The finished ceiling has covered most of the bolted connections.
The hip rafters were designed as “inverted” trusses and expose the lower 2″ of the original 2×8 hip rafters installed in 1957! The upper ends of each hip rafter are supported by a steel plate bolted into the existing rafters and first full span truss. This full span truss is designed as a “carrier” or “girder” truss to support both hip trusses plus 4′ of roof and ceiling weight.
The original hip rafter system was sagging by as much as 4 inches. During installation of the steel trusses, the hip rafters were bent up to completely eliminate the noticeable exterior sag. The completed system was then fully loaded and the steel trusses showed no measurable deflection at the midpoint.
