Repairing Glass Patio roof

I have a neighbor who has a glass patio roof (as photos), and it leaks badly. My view and I am sure most of you, think that it should be replaced. However at this time, they do not want to do it.
As it is in the Rainforest in BC, and a 2 1/2 degree slope, their is no margin of error in this part of the country.

The only thing I can think of a temporary repair is a peel and stick membrane, maybe 6" wide to go over the seams of this roof.

My question is what membrane sticks best to glass?

As a temporary repair I would seal it with Tremco caulking. It should do the job for a long time (years).

Biggest problem I can see here ...
And probably what caused the leak
Is it appears this is a flat roof
It should have been built with some degree of slope
So the water would run off ... vs sitting
So even if it’s a temporary fix
The issue isn’t going away

Other than that

Depending on where the leak is.

3m (Or other company) Security film could work...applying it across panes. It may not look fabulous and may not be easy to apply though as you're working on a horizontal surface.

Alternatively wouldn't caulk work the best?
