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

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.

sometimes for the right application "C" channel is needed, it all

for instance, on a bitumen roof application it hides the nailing strip

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