Conservatory Roof Panel Slipping

[Nick 156]

One of the roof panels in my conservatory has slipped down, leaving an inch gap along the top of the roof. Is it possible to cut off all the silicone that's holding it to the external plastic rim (between panels), push it back up and re-seal it? I don't want the already big gap to become worse! Any advice would be appreciated.
Best regards

if fitted correctly,there shouldn't be any silicone on the roof.the caps on the glazing bars should be tight enough down on the sheets to hold them in place.over a period of time the silicone splits and cracks,and the problem starts again,there should also be a 10mm gap between the sheets and the mid point of the glazing bars,this is to allow water to drain away should it get past the glazing bar caps.how old is the roof ? are the sheets the right thickness for the glazing bars ? hope this helps.

Thanks for your comment bendylow. I cannot see any silicone on the exterior, just guessed that was what created the watertight seal? It feels rock solid, and will not simply slide back up using brute force. I cannot understand how this has happened, as all the other panels are exactly where they should be. The conservatory is less than 5 years old, but was installed by the previous owner.

Should I be looking for the caps on the glazing bars then, try and unlock them, reposition the roofing sheet, and lock them again? If so, where are they typically located, and do I need a particular tool to unlock and lock them again?

Many thanks once again for your help.

Best regards

Do you have one of these type of glazing bar?

or one of these push down plastic type glazing bar?

Hi masona,

Based purely on how they look, I think we have the push down plastic type glazing bar. Will having these make it easier to solve my slipping problem?
I look forward to hearing from you.

It could be the top plastic cover maybe loose, can tap it down gently with a block of wood & mallet or it could be a wrong size rubber sealant or worn. However prise a blunt tool into the gap between the top and bottom of the glazing bar and lift it up and remove completely then use something like stick-on glazing tape on the bottom runner then refit the sheeting etc.
Glazing tape available from most DG shop.

A photo will tell me more.

Thanks again masona, I think your suggestion is probably my solution. Before I tackle it, please find pictures below of the problem:

Should I try and remove these glazing bars with a blunt tool then?

Right where the gutter is, take the end cap of the glazing bar and take another picture if you can at the end section of the glazing bar

Hi masona, I cannot get the end cap off right now, but here's a close up:

Hope these camera phone pictures are clear enough

Thanks again for your help

Sorry to be a pain, the picture too big to see closely, the glazing appears to be metal now, am'I right? The end cap, just prise it carefully with a small screwdriver unless it's screw which need to be undone.
