    Old unfelted roof

    Hi we have a 1930 semi, the roof appears to be original and is unfelted. someone in the past has stapled plastic sheeting and bitumen felt to the underside of the rafters. I think in an attempt to stop dirt blowing through as I cant see signs of leaks. Can I replace this with a breathable...

    damp at base of chimney

    We have a 1930's semi. I have opened the builders break on a disused chimney, but we have damp at the base. Would this most likely be from the base or from needing the chimney capped?

    Warm roof sealing

    We are in the middle of a rear extension, this has a warm roof. where the joists run over the external wall there was a gap between the insulation and the wall. i.e letting in cold air from the soffit, this would have been below the warm roof and above the plasterboard ceiling. I also had the...
