My mother's house has a "garden room" style conservatory a bit like this one. One of the triangular roof panels seems to be shifting away from the wooden frame, so that a thin wedge of daylight is showing through - about half a centimetre at its widest, easily enough to let rain in.
I got up on a stepladder to take a look, thinking I could shift the thing back into place, but it's impossible - won't budge an inch. It's made up of several layers of thick plastic. Maybe some sort of sealant would do the job, but is there anything thick enough so that it won't just drip right through?
Anyone had a similar experience? Any suggestions?
