As the moisture migrates upwards to the colder attic areas during the winter months the relative humidity is increased to the point that condensation can occur on cold surfaces.
Excess moisture in attic space.
Insulation is responsible for keeping warm air inside your living space and out of the attic where it can lead to condensation.
If you have taken the proper steps to remove excess humid air from your home and you re still having condensation issues it might be time to check the attic insulation.
The key to ensuring moisture doesn t find its way into your home is by finding out where the water is.
Your problem is warm air leaking into the now cold attic.
While many homeowners usually associate dampness with basements or crawl spaces attics can suffer from moisture problems just as easily which can lead to damaged insulation structural issues and problems with mold.
In the past air leaks existed but the attic was warm because of the lack of insulation.
The solution is to air seal between the attic and the heated space below.
When the air is warm it holds a lot of moisture so the relative humidity was low and there was no moisture problem.
Excess moisture can jeopardize your home s structural integrity as it can lead to damage of your home including your walls floors furniture and precious storage and cause health annoyances including allergies or difficulty breathing.
