I read/heard about critters, bees, etc. but I decided to go for it anyway.
For a number of years I had it partially roofed (ceilinged, I guess) with
semi-transparent corrugated fiberglass panels and when I took them
down there was no indication of unwanted guests. I get nests behind
my shutters and in a few other places, so I know I have wasps, but the
under-deck panels haven't ever been a problem.

I need 12' to simplify things but that doesn't look like a problem. I
was thinking about steel or fiberglass but PVC may be lighter. This
looks like a possibility too. Clear would allow me to see the
critters under there. We have squirrels making a nest in our gas
grill (hasn't been used in years) now. I wouldn't want them under
there.

Pvc can be heavy, could try Polycarbonate Twinwall if you want some
what clear.

PVC *can* be heavy, but these panels aren't. The 2.2' x 8' panels I used were
something like 4 lbs each.

The only reason I needed SWMBO's help mounting them was because they
are so flexible, especially while trying to hold them up to underside of the
joists.

Weight was definitely not an issue.
They weren't too floppy to keep the pitch?

The pitch is created with strapping across the joists, like
hanging drywall on a ceiling. Difference is, the strapping
thinner near the house (none right at the wall) and thicker
as it approaches the gutter. If you want it perfectly flat
along the pitch, use more strapping.

Mine isnt perfect, probably could use one more strap, but
theres enough pitch that it never backs up or leaks. It's
a storage area, not a formal dining room.

I've got a piece under the stairs up to the deck also. Great
place to keep the 2 wheeled garden cart.
