I had a guy install a whirlybird-type vent in my roof.. those non-powered turbine types. Upon cutting the hole to install the vent, he accidentally cut a notch in the rafter:
There are two notches in the rafter (one on each side of the circle he cut, 15 inches apart). I'm looking for advice on how to reinforce it. I'm thinking of putting a nail plate like this, spanning each notch:
Should I put nail plates on both sides of the 2x4 (sandwich the 2x4 between two nail plates.. meaning 4 nail plates in total.. two for each notch)? Or would you recommend a different approach entirely?
If you're interested in more detail. The 2x4 is the er.. 'top chord' as defined in the attached pic. I've circled the region that was notched. It doesn't support anything other than the roof.. single story house.. about 32 foot span (i.e., the 'clear span' in the pic is 32 foot). Sounds like a nail plate is a dumb idea, I'll scrap it. I'll either sister a board to it or just leave it alone. If the added detail changes anyone's thinking on either of those tacts, please let me know.
