Should you decide to install aluminum facia covering, it can be bent at both the top and bottom to look like this "[" with the upper edge under the shingles (but above the felt) and the lower edge covering the bottom of the facia board for a nice clean look. I'd probably make the under- the- shingle portion about 2 inches wide. Then I would dispense with the drip edge. Some purists will say that you will still need a drip edge but then the appearance would be somewhat compromised and in my opinion it is not necessary. If you dispense with the top bend for some reason, I would definitely install a drip edge which would overlap the aluminum facia covering. Be sure to get the right style drip edge for this application. You'll find an extra set of hands and a second ladder very helpful if you decide to do the job yourself. It is certainly doable as a diy project if you can rent a brake. You will want to purchase some aluminum nails for this project. You can get them with white enameled heads to match the aluminum.
