There are only about six rafters that are in that condition, localized to
one area. Most rot are at the end of the rafter where the fascia is
attached. I think by sistering the end I can support whatever weight I need
to support for the fascia.
If I need to get into the attic to double the whole thing I can do it, I
plan on ripping out all the ceilings anyways so it's possible, but is it
necessary to double sister 18' of rafter when the damage is at the last six
inches? It's not impossible it's doable just more work but I thought that's
an overkill.
Thanks,
