The roof in my garage was made with manufactured trusses constructed with 2 by 4 lumber and spanning 24 feet. Although the attic does not have any construction (any living space nor storage), and there is plenty of room to pass wires, the constructor decided to bore 3/4" holes through each of the trusses within millimeters of one of the lower end corners in the lower chord next to the metal connecting plates. Some holes where drilled slightly at an angle removing even more wood than a straight hole will do.
While the roof survived many years, every time I pass through the garage I feel I need to do something about the situation, even more so considering the increased storm activity in recent years.
I already rerouted the wires and I would like to reinforce the trusses to at least their original strength but I am not sure how to do it.
What makes the situation even worse is that my house is the first house ever build (his own house) by the creator of one of the most enduring home improvement TV shows, now airing next to "This old house" on Create TV. I really trusted I would benefit from the expertise and I was deeply disappointed having found countless examples of poor craftsmanship that have eaten away the last five years of my life fixing the place. This is one of the very last problems and I really don't know how to tackle the situation.
