ABSTRACT:
An add-on roof reinforcing brace is disclosed for buttressing the structural strength of roof rafters which have been weakened by age and deterioration. The add-on brace of the present invention provides a quick and economical means of vertically orientating a square-cut stud, between an angled roof rafter and a horizontally disposed ceiling joist. To this end, a joist attachment member secures one distal end of the stud to the ceiling joist and a rafter attachment member secures the other distal end of the stud to the roof rafter. The rafter attachment member includes a sleeve for attaching said rafter attachment member to the other end of the stud, a saddle-shaped member for attaching said rafter attachment member to a roof rafter, and a pivot member for pivotably interconnecting the sleeve and the saddle-shaped member. The sleeve member may be selectively angulated relative to the saddle-shaped member to dispose the stud in a generally vertical attitude regardless of the geometric angle between the roof rafter and the ceiling joist.
