    Hi
    Got attic converted last year and have noticed the last few days (cold weather) a lot of condensation on the back of the roof felt. The builder put 50mm rigid insulation in between rafters but by looking at it it was put it pretty loosely.
    No insulation was put on the back of knee walls. Is this just down to the cold weather or should I get it checked out.

    The warm moist air is leaking in the attic space and condensing on the cold roof felt. Sounds like there's little or no ventilation in the attic space either.

    So sounds like I need a roofing company in then.

    We just put in venting roof tiles spaced at regular intervals along the roof to encourage ventilation.
