why not just bend the aluminum so it is tucked under the shingles?

You can, if you have a brake. It's called a drip edge.

that's BS
my wood shingled roof has no drip edge
haven't seen any substantial damage yet (20 yrs.later).
it's the gutters that seem to always cause the damage from what I have
replaced for customers.

If you're going to reply to something, don't take it out of context. It's
not BS to what I said. WTF, you have a reading comprehension problem also?

I said: "Drip edge "is" neccessary, depending on a lot of circumstances.
For
instance, if your structure has a aluminum or such covering, the drip
covers the top edge of it. If drip edge isn't installed, you will get
blown, or dripping infiltration which will eventually cause substantial
damage."

sometimes for the right application "C" channel is needed, it all
depends on the trim.
for instance, on a bitumen roof application it hides the nailing strip
around the perimeter.

Ut oh, I think I smell a butcher.

I am a firm believer in drip edge for the bottom so it overlaps the
fascia board
but not on the rake boards unless it is a re-roof (it hides the edges of
the original roof nicely).

It is, it's a butcher. Someone to lazy to trim edges. I've seen hundreds of
your kind in my days. The faces change, the name remains the same, butcher.
