I have inherited a leaking conservatory and found that all the leaks occur where the outdoor screws screw though the polycarbonate roof to the wooden beams on the inside. My god - what a botch job.
Funnily enough, some of the screws were were mounted using a cute waterproof insulating kit consisting of a rubber washer and an even cuter rupper cap. These do a great job at keeping the rain out.
Does anyone know where I can can hold of this water proof insulating kit for screws?
