Coping with wet insulation.
Wet attic walls.
A leaky wet wall will have a cooler temperature than the surrounding wall.
There are many signs that an attic is wet.
Infrared cameras detect heat and can indicate the temperature of a wall.
Dry the wall surface with a fan heater then tape some kitchen foil tightly over the affected area.
Alternatively internal insulated dry lining can be.
Train an infrared camera on a wall with a leak and look to see which section of the wall is the coldest.
Prolonged wetness will rot out the roof sheathing.
Often this is first noticed when re shingling.
If the attic has blown in cellulose check to see if.

At higher levels relative humidity condensation can even occur inside of the house on windows cold walls or ceiling surfaces.
