Often this is first noticed when re shingling.
Wet attic walls.
Moist or wet insulation.
There are many signs that an attic is wet.
What to do about a wet attic.
This moisture can make your walls feel wet as it is prone to causing damp patches on walls after heavy rain.
If the surface of the foil is wet after 24 hours you have condensation.
At higher levels relative humidity condensation can even occur inside of the house on windows cold walls or ceiling surfaces.
Eventually this moisture can seriously damage your walls or foundation.
Infrared cameras detect heat and can indicate the temperature of a wall.
Coping with wet insulation.
Attic water damage home water damage household water damage wet insulation.
Prolonged wetness will rot out the roof sheathing.
If you have ceiling leaks only in the spring it may be that ice has been forming on the sheathing all winter and it suddenly melts when a warm spell arrives.
During that time it will also degrade wooden structure and trigger attic mold growth.
Find the cold leaky part of a wall with an infrared camera.
The addition of pumped cavity wall insulation can help and external insulation will keep the structure warm while sealing the outer walls.
You may even see water flowing onto the floor from the edge of the wall.
A leaky wet wall will have a cooler temperature than the surrounding wall.
If the attic has blown in cellulose check to see if.
Wet cellulose is generally not salvageable and needs to be removed then new material blown in to replace it.
Depending on how tight a house is constructed and the outside temperature even a relative humidity of 30 percent may be too high.
Train an infrared camera on a wall with a leak and look to see which section of the wall is the coldest.
High levels of humidity inside the home cause moisture to condense on the walls and sometimes the windows as well.
Dry the wall surface with a fan heater then tape some kitchen foil tightly over the affected area.
If you have ever noticed that the inside walls of your home are wet and actually appear to be sweating you probably have an issue with high humidity.
