Reroofing - do you tape the edges?

The sides are aluminum and the roof is plywood. There is a 1 to 2 inch gap between them. I think i should cover the gap with something , like duct tape or butyle tape or something. I will be covering the roof with EPDM 60 mil.
Any suggestions would be great

Thanks everyone
Ok no duct tape , and ur right , that gap is too big to just leave space .
I will cut some strips of that pink panther insulation and give it a curve,and place it between roof and side.
I was thinking of eternabond but it’s expensive and it will be covered by the epdm
Do you think this can work :

Just put a new roof on my TT. They make a special tape I purchased from my local RV dealer that was extra thick with a cloth top. I ran out of cloth tape towards the end and used extra wide gorilla tape for a small portion. I also put the cloth tape on the seems of the plywood decking. I only had about a quarter inch gap between the roof decking and siding. Something doesn't sound right if you have a 1 to 2 inch gap. Do you happen to have a picture?

Something has to be missing. There should be no gap. You want a solid firm roof corner where the roofing material meets the side wall.

That's a large gap. I'm wondering if it could be filled with canned spray foam (Great Stuff), let it cure and trim off the excess?
Or just cut some wood to fit in the gap?

I would not just tape it, that would leave a weak spot on the roof.
Definitely don't use duct tape.

After you fill the gap and replace the roof, use Eternabond to tape the roof edges and any seams on the roof.

Maybe someone will have a better idea.
Let us know what you do to correct the gsp.

Not duck tape! EternaBond tape is the hands down best IMO.
