Applying Eternabond Tape to edge of roof

The tape can be a real bear to deal with on a nice straight, flat seam. You will have your work cut out for you in this application. The way that I think I would try it is to lay it down on your roof with close to an inch hanging over the gutter side. Once you have it down, fold the 1" lap down over the gutter trim & screws.

I agree. Especially the part about covering the screws. They won't ever come loose with eternabond over them.

I applied tape all the way around the roof edge (pop-up). I cut the 4" wide pieces about 30" long. Starting in the back, I laid it so that each piece was overlapped a couple of inches. I want the seams to be facing towards the back so the wind could not pull it up.

Everything held well except the front edge, which continues to want to lift. I'm going to add another 4" row so I can roll it under the roof edge.

So, just so that I understand, are you guys covering the screws too?

PO of my camper used Eternabond to cover some roof and siding damages.
Maybe he wasn't too good at the job, but the tape let the water intrusion and the camper had quite a bit of dryrot under, while removing very messy tape was job on its own and it left dark spots on white siding.
The only use of it I would consider is to make traction tape on the roof, where you still don't have any problems and you don't see from ground level.
Don't count on the tape to seal the leaks.

That makes absolutely no sense. That's its sole job. Just because your previous owner put the tape on long after the leak had started, don't think it doesn't work. The tape will seal the leaks but won't address any damage already done.

I've used it myself on that very same edge seam the OP is asking about and found it to be unsatisfactory. There were no leaks, and I did all the proper "rain-dance" prep work beforehand, then rolled and rolled and rolled the tape to activate all those micro beads (of snake oil).

It looked perfect when I got done, and there was no indication that there was anything amiss..........until I had to peel some off to replace something on the roof (can't remember what I was working on, this was about eight years ago). Guess what I found under the tape? Water!

I peeled every bit of it off and re-caulked with Dicor self-leveling and lap sealant.

I wouldn't trust tape to seal anything but a perfectly flat surface with no curves, edges, bumps, or anything that you have to form the tape around. The vinyl backer will not stay formed around irregularities, and will lift the adhesive off the roof.

I think it's virtues are all illusory.
