This question could be slightly misleading because I am not 100% sure of the terminology. I am replacing an old gutter - see existing installation below.
My understanding (from this article) is that I should attach gutter flashing underneath the shingles and have it (the flashing) come over the back edge of the gutter. However, my roof already has a drip edge installed (not gutter flashing), and it also has a small trim board attached to the fascia; this trim board is tucked underneath the drip edge. Also, the gutter is spaced off of the fascia by a bunch of little spacer blocks - this creates a gap between the gutter and the fascia board.
My question: is there any reason I shouldn't remove the spacer blocks and attach the new gutter directly to the fascia board? If I did that, I don't think that if I installed gutter flashing it would reach all the way down to the gutter, but considering that the drip edge would be hanging out over the gutter about an inch (the width of the little fascia trim board, plus the drip edge itself), I am wondering if I might be okay without adding actual gutter flashing...
Or, would it be better somehow to attach the gutter such that either the existing drip edge comes over the back edge of the gutter or add a piece of gutter flashing that extends down over the back edge of the gutter?
p.s. Can you tell me what that trim board on the fascia is called? That trim goes all the way around my entire roof-line (you can see it on the sloped edge as well), and I bet there's a term for it that I'm unaware of.
