Roof Truss Repair
Here's a good picture of a wood roof truss repair. This
looks like it was done by a building professional. If I was to guess,
this roof truss was damaged and while the city or county framing
inspector was inspecting the house, he probably noticed the damaged roof
truss and it was repaired properly.
Here's another view of the roof truss repair.
Using bolts and washers, instead of using nails is an excellent way to repair damaged framing components. It might take a little more time, but the end product of the home repair will be a little bit better than using large nails.
