Had some work done on roof recently. New slates and they put a new waterproof membrane on. Since its been done upper part of house seems to lose heat quicker. Was up there other day seemed pretty drafty and edge of membrane (well at edge seemed to be blowing a lot, not sure if it was waterproof membrane or not). Keep meaning to phone them but have a feeling I might be fobbed off as I'm clueless. Guess membrane might not be fixed properly at edges or some point, could something like this make such a difference to the temperature of our house?[/u]
