We use these http://www.roofingsuperstore.co.uk/user/u/prod/l/1589.jpg to get the cables through the roof but we've had two fail - resulting in wet ceilings needing re-plastered. Both jobs were installed for around the six month mark before the problem was apparent. It's a relatively small % of jobs that we've done and they've been sorted but has anyone else had this problem?
