I am starting some dry-rot repairs on an exterior wall. I'd like input from anyone who has replaced studs and/or sections of the sill on a garage exterior wall on a JE-73 or similar flat roofed Eichler.
The wall is a long wall which is parallel to the garage beams. Apparently because it has no windows, the architects did not put a beam at the top of the wall. The nearest beam is ~4' in from the wall. The garage door ends of the beams are supported by a 4x10 transverse beam which rests on short balloon walls at each end (which have their own bolted sills) and a 4x4 center post.
This arrangement suggests to me that this exterior wall is a bearing wall. A simple analysis suggests that it carries half the load of the roof between the nearest beam and the wall, although there must be a cantilever contribution since the 2x6 T&G roof planks extend over the nearest beam to the center of the roof.
Does it make sense to pick up a pair of jack posts and to use a 4x4 under the roof planks and another (or perhaps a 2x6) on the floor beneath them to temporarily carry the load?
I just had this work done a few weeks ago. I had the siding replaced on the entire side wall of the garage. This house has a flat roof over the garage.
I was very concerned of what I'd find after the siding was removed. Fortunately for me, there was a small portion of two studs that had to be cut out and patched back in at the base. The bottom sill plate also had a portion about 6 inches cut out and patched in.
If your framing is not too badly rotted or you have little areas to repair, can't you cut out rotted areas and replace with new studs and such without jacking the roof to support the weight?
Unfortunately for Eichler homes that have areas of no roof overhang, the siding takes a beating from sun and rain.
