John,
If the roofing you are talking about is similar to traditional
corrugated, but with flat valleys and ribs instead of a sinusoidal/
curved profile, we just completed an install like that using the
Corrubracket from S-5. (it also works for the sinusoidal profile) No L-
feet required. The bracket is extruded aluminum with a two-pad profile
designed to span over a roofing rib. There are two tapped M8 holes on
top for attachment. It worked great, and it came with a sticky sealant
already attached to the mounting area. The issue we ran into was that
since there are 4 mounting holes in a ~3-3.5" square layout, you can't
really attach to rafters/truss chords alone, as one pair of holes will
miss the structural member. We had to use some additional blocking
underneath the roof decking. That was a pain, but I was pleased with
how it worked otherwise. Worth checking out.

Wrenches,
Do you have any tips, stories, methods for mounting L feet on
the corrugated metal roof that has short flat spans and ribs.
After all these years, I am facing my first install on this kind of
roof. We originally were going to install 6 top of pole mounts but
he decided the neighbors would not like the appearance so now we are
looking at a 20 x 40' metal roof on the garage. The customer asked
about flashing the L feet. I'm at a loss to figure out how to do
that.
