:> I'm in Berkeley, CA. The winters are mild, no snow, but there are nights

:> look to be in good shape. But the plywood (there's some 1x6 boards too!)
:> is basically trashed, so I'd have to replace that stuff, or maybe not if
:> I nail on nailing strips for metal roofing, no big deal either way. I
:> have basic tools like a circle saw, saw horses, ladders, etc. and a
:> concrete courtyard to work in.
:> 1. Is it feasible for me to do this myself, and
:> 2. How much would the materials cost?

Yeah, I grew up in L.A. and I have relatives from Santa Barbara all the
way down to where you can see Mexico from the porch (La Mesa)! Not a lot
of rain. But when I lived in West L.A. I remember that just about every
year there was one day when it rained steadily all day.

Yeah, there's much about the property that's not code. It's no surprise
to me, but I didn't know that code is minimal 1/4" per foot.

Yep, that would be code.

Back and the high side are cinder blocks, period, and they seem solid
and the mortar seems great AFAIK. The bad wall is wood, has two windows
(mostly broken out), and the wood's totally delapidated. Someone slapped
all kinds of stuff on that wall including plywood, a couple of old doors
behind a large broken out window, the works! That one side is really
shabby. In fact, when I bought the house I didn't have a key to the
garage and I got into it initially by going through a hole in the bad
wall! It allows for ventilation on the occasions when he tarp has leaked
into the garage. It also lets in animals such as cats, squirrels and who
I think the worst problem with the garage right now is the concrete
floor. It's been messed with evidently by a close-by large plum tree.
However, it doesn't seem to be presenting an immediate problem. A slab
near the door (I totally renovated that door with new springs, plywood,
paint and lock) is raised around 3 inches, I think!

Don't know about that. Berkeley is kind of a bitch for permitting

Wayne and I are friendly, have visited each other's house several times,
although I haven't seen him in quite a while. He helped me when I was
having the house reroofed. I met him here. He's very astute and
grounded, knows a lot about a lot of things, is very good at researching
his projects and planning them. Does very good work.
