Doing a new garage roof.

I noticed at Lowes that they have several different drip edges. Is
there supposed to be a different one for the rake than for the eaves?
Also, does the drip edge install right up against the sheathing? or
should there be a little bit of a gap. I have 5/8 sheathing and assume
standard 1" drip edge. The type F is the standard for eaves I think,
but this type B is a wrap around for the gable end from what I could
tell--kind of like a 90 degree wrap.

What is the standard practice?


IMHO, they should outlaw the B channel. Water will follow that bend right
back into the fascia. Again, IMHO, B channel is made for those who want to
take a short cut at your expense. They don't like trimming edges of
existing shingles, so they cover them up, which creates problems which
aren't noticed until they're long gone.
