Leak in bedroom ceiling

johnbaptiste

About 3mths ago I had a leak in front bedroom of my 4yr old property, which NHBC covered the cost of replacing ridge tiles as the felt underneath didn't cover the ridge. Now I have a serious leak in back bedroom, my roofer says its because of poor quality of roofing felt that has many holes in it, but obviously the rain must be coming in through the roof tiles, although no one can see where from. Have had visit from NHBC who will be sending out their own roofing contractor to investigate, but didn't say whether they would be prepared to cover the cost this time. Has anyone else had the same problem, I have the fear NHBC will say its not covered who should I contact should this happen. Any advice would be helpful. Thanks

I am a bit puzzled by this. Going back three months to your underlay ... it is common for it to stop short of the ridge, and this allows ridge ventilation. Again ventilated ridges are common. So why was it put across the ridge? Perhaps you have a different detail?

I can only guess at your current problems, which seem unusual. Have you insufficient headlap on the tiles, or is the pitch too low? Are you are getting wind driven rain getting up past the tiles? Do you have a valley above the wet bedroom?

OK you have manky, holed underlay but here NHBC may try and bounce matters back to you. You accepted this when you purchased, and you have obviously not sought to get it rectified.

But be aware of a general principle. NHBC have a diabolical reputation. This means the home owner must be as sharp as a shaving razor in dealing with them. If you do not know your tile/slate, and manufacturer, and have then checked all the technical design and installation data then you stand a huge chance of being hoodwinked. This in turn means a brutal truth - it is your home and your responsibility to identify where the problems lie and what should be done to correct them.

Put matters another way - can NHBC be trusted? The answer is no, and by way of example even your NHBC "repaired" underlay sounds questionable.
