we bought a cheap pvc sunroom last year (big mistake its not got a reinforced frame just hollow pvc supports), it is very flimsy and drafty its not a proper pvc reinforced framed conservatory.
the roof keeps leaking where it joins the house, we have put proper lead flashing on it which is in the house render (used a grinder ) and mortared in and bitumined, but i think where the conservatory is flimsy it can move slightly in high winds like today and the bitumen and mortar keeps cracking and today i have 4 leaks and bowls catching the rain water.
apart from buy a new conservatory, does any one have any suggestions to stop the leaks

thanks in advance

Short of reflashing it with something flexible (a thick butyl maybe?) you need to stop it moving ... can it be more firmly affixed to the wall at the top?
I'm sorry you've got a duff product Bongo ......... sounds awful :o(
A common mistake with cover flashings, is that they should "stick" to the roof underneath. Back in the day, when it was common to dump a heavy sand & cement fillet along the junction, good practice was to lay newspaper on the roof so that the fillet DOESN'T stick to the roof ........ only the wall.
This allowed for a bit of movement without taking the flashing/fillet with it.
Fix the structure to the house by all means. In fact, by the sound of it, fix it to anything you can find :o)
It needn't be a write-off.......... just needs fixing,stiffening, and a bit of bracing to make it rigid. Any decent carpenter or builder could show you how.
