Replacing hinges

I'd be wanting to understand why they broke, because I would expect there to be an underlying cause. I'm not completely sure if it was true in 1998, but if there is a significant amount of wood involved (there was in earlier versions of the roof) then I would want to check for rot in the woodwork first.

I can recall a thread here previously but the cause was slightly different - in that case it was a failure of the hinge at the base of one end panel, and that seemed to have been caused by water pooling under the front edge of the roof and rotting the wood crosspiece.

A/S faced a dilemma with the side panels, because they wanted to make them light, so they could not be very thick. This meant that anything screwed into the panel with a self tapper will tend to loosen if stressed. We had this problem on ours with the catches at the top, and I can remember removing them and fixing the opened-out screw holes before reinstalling. You might find a similar problem with the lower screw holes, but you'll probably only find out when you come to take them off.
