Because of the roof structure and decorative nature, anything like felt
would be very difficult, so we were wondering about some sort of heavy
duty flexible paint to slop on and hope it would run into the cracks and
gaps and seal the roof. It would need to be a more appropriate colour
than black or whit and access to the front is OK, but the back is more
of a problem because of trees and a wall.

What paint or any better ideas?

Silicone sealant?
It looks as though the previous owner has tried this, but it looks
impractical to apply. At the joints between the roof panels, there are
all the other structural bits of wood. The water gets in and drips out
somewhere else inside, of course

I've found a picture of a similar one at

if it comes out.

OK, try

and see the second of the close up photos from the box at the bottom of
the page to see the roof.
