I live in a mid-terrace street house and I had a problem with water staining in the corner of my small back bedroom, near the eaves. I thought this might be caused by condensation coming through the plasterboard from above. One of the roofers who came to price for the job pulled a couple of tiles off at the corner of the roof and showed me where the felt was wet underneath and thereby demonstrated that it wasn't condensation but rain getting underneath the tiles.
He told me that the secret valley between my roof and next door's wasn't sealed properly and needed to be cemented properly all the way up to the ridge. He also said he could sort out my condensation problem by fitting a dry ridge to the roof and by replacing the felt under the first three or four courses of tiles with breathable felt (about 9 or 10 feet long at the eaves). He also said he would install five vent tiles which would help to remove the condensation.
He did these four things but I don't think it's made much of a difference to the condensation problem, although I can't be sure because we haven't had a really cold snap since he did the job three weeks ago, when the condensation was pretty bad. Also, I've noticed that where he put the dry ridge on he's managed to put long screws through the roof felt at 5 different places. I've also noticed that where he's fitted the vented roof tiles there are fairly big gaps between the roof felt and the pipes that come into the loft from the vented tiles and I'm wondering if when there's driving rain it might come in through these gaps.
The roofer who did the job had a mate with him, who he left on his own two three times during the day, once to get materials and another time to get their take-away dinners but the total time between them arriving in the morning till leaving in the afternoon was less than 7 hours. He charged me £1000 and I feel that I have probably been somewhat ripped off and I'd be really interested in what any of the professional roofers out there have got to say on what I've written here. Thanks.
