I have an old covered pergola that has roof leaks and subsequent rotted rafters.
My plan is to replace the roof to prevent further water intrusion, and as a part of that, remediate the rafters that are rotted.
As far as I can tell, remediation has 2 forms:
-
Chip out rotted parts, use Bondo to replace
-
Cut out the rotted section entirely, and put in a new section of wood, and... Affix the old parts to the new parts with....screws and a metal plate? Or maybe another piece of wood? Googling says this is called sistering, but I don't know my way around carpentry.
I'm really iffy on the second one. One of the rafters has visible rotting and swelling about halfway through, so I don't think Bondo will do the trick there and I'm at a bit of a loss as to what to do.
Any insight or advice would be appreciated!
