Survey of a property in Abbeydale Gloucester for suspicious leaking roof that turned out to be a severe condensation issue.
Speaking with the occupant then surveying the property it was evident that in the last 7 months cavity wall and loft insulation was installed. These new home improvements can significantly help with keeping your home warm.
However, as highlighted in the picture there is water forming on the underside of the sarking (felt) this is a result of the loft temperature being considerably lower than the dew point of the main dwelling.
With free water forming on the underside of the sarking, high quantities of water droplets are falling to saturate the loft insulation through to the ceiling.
