A previous owner installed or modified the 20' bottom chord elements of my 1950's era garage roof structure resulting in bottom chords that are a patchwork of varous lengths of board (mostly 2x6) nailed together to span the 20' run. There has been no sagging of the roof or outward bowing of the walls over the 15 years I've lived here, but I have never been comfortable with this arrangement. Anyone think I can safely correct this design by attaching proper, purpose made 20' chords on the opposide sides of the rafter ends, allowing me to then remove the cobbled together chords?
Picture attached is a view of one of the chords taken from the floor of the garage looking up toward the inside of the roof.
Thanks in advance for any advice.
