Retrofitting gable end drip rail

The carpenter that built my house used a 1x2 finger jointed wood strip across the top of my Hardie board fascia. Then, it was painted poorly. Within a few months, mold/mildew was bleeding though. After much research, I decided to just remove it and replace it with a wide drip rail that will cover where the wood strip was.

My question is what can I used to attach the drip rail? I know the absolute best way to do it is to nail it from the top under the asphalt shingles, buts going to be a lot of work. I have 6 gables and over 300 lf to do. I was hoping I could use constructive adhesive, butyl tale, nails, screws, or some other product to attach it on the face.

In my research, I came across some other profiles that were made to simply attach from the face, but it wasn't wide enough for my application. That stuff would have to be attached from the face, but it didn't say how.

Any ideas, suggestions? If it helps, I live in the SE where it gets as cold as 20 F and as hot as 100 F.

Your gonna need to pull nails to get it under the shingles. Likely a lot of nails.
I would be installing 1x2 pvc instead

Ditto what PatChap said. If the drip rail isn't under the shingles then it doesn't give you the protection of a drip rail. Your shingle overhang should already be an inch or so, without the 1x2 there, your overhang becomes extreme.

Re: Retrofitting gable end drip rail

I agree 100% with the others.

To do a drip edge right would require pulling a lot of is some math

300 feet x 12 inches to a foot= 3600 inches
3600 inches 5.5 inches per metric course=about 654 nails +/-

seems like a pvc replacement is a no brainer
Don't look at me. I didn't vote for either one of them.
