Repairing broken roof struts
I finally got a licensed engineer out to take a look at this.
The working theory is that the truss was damaged when the home was built, some 30+ years and 2+ owners ago. The rest of the truss system looks like it's in good shape. Sounds like I'm either the first person to notice this or the first person to care.
The solution they drew up was to put a 30&quot; 2x4 on either side of each damaged truss member and secure it with six 3&quot; structural screws on each side of the break (so 24 screws total per damaged truss member). Took about an hour to do this myself, and aside from some sore legs and a serious amount of sweat it wasn't too difficult.
The lesson here is to call around. The first person I talked to was a builder who suggested taking off part of the roof and replacing the truss. Later it was suggested to me to consult with a licensed structural engineer who came up with this solution.
