Notched Top Plates and Rafter Extensions
Shortly after I bought my home last year I started airsealing and adding insulation in my attic. It took longer than it should have to realise i was seeing a pattern of something odd. So I took photos and started googling and asking friends. In every rafter bay of my 1953 gable roof (Site built trusses with plywood gussets! and a disappointing 3″ of space between top plates & roof deck.) there was damage. It didnt click in my head till I saw the birdsmouth cut on the top plate, that’s when I took notice! (the others didnt have that clean cut) I havent found anything like this on google so I called in a roofing company. The roofer said the house had been originally built without a over hang and at some point someone decided to nail on some length to the rafters… And well, Murphys Law strikes again. The roofer was entertained and now has a new story to tell when having beers with his coworkers. He pretty much shrugged his shoulders and said no worries.
This seems like something I should worry about though and I’m posting to make doubly sure it’s “Eh, no worries” as the roofer said. To my uneducated eye I dont see anything wonky like leaning walls or roof issues but then again I could be staring right at obvious issues and not registering them. I am still working through the attic and as of yet it is just the one top plate birdsmouth and the rest were all cut rougher at a sideways angle (I’ll post pictures so you get it). What’s your opinion? And has anyone else seen or heard of this before?
