Observed tiny holes bored in roof trusses for wiring passage. I had to peek under the catwalk board from the entry ladder to get this picture, sorry for the crumby quality. There are at least (5) ~3/8" holes drilled in what I can see. Although these don’t seem to substantially damage the integrity of the structure, my understanding of trusses is “DONT SCREW WITH TRUSSES!!!”
Am I correct to recommend a structural engineer to further review the trusses? or is that overkill for this instance?
