100 odd year old pitched roof query
Discussion
Yes quite a few of the rafters look to be notched over the wall plate, although I cant see them all clearly I suspect they may all have been like this. So, with this in mind how do I go about repairing the rotten rafter/joist ends without causing my roof to come crashing down around me?
Replacement is the best way really, shame it wasn't spotted and done when the top was renewed. It's a bit of a lazy, rough roof construction, possibly been renewed at some time. For 'ridge tree' see 'Ridge board', i've never heard it called that before.
If you do just let pieces in then they'll need plating either side and bolting through. I once did one where galvanised steel box sections were made which were slid over the existing joists and bolted through.
Try to work out what is stopping the base of the roof and walls from spreading, you need to retain that (or create something if there isn't!), it's usually a truss or two which does this. Do a good overall inspection to check for spread, look for signs or even employ a long piece of string....
It's impossible to say more without seeing more, it's probable they've tied the base of the rafter into the wall plate and/or straight through a ceiling joist to do this.
