Our home is over 50 years old. We have noticed there is a moisture problem in the attic. We also have water in our crawlspace.
The attic has 1/2 blown in insulation and 1/2 roll insulation. We put plywood done on the side with roll insulation, but put spacers between the plywood floor and joists to allow air movement. The bottom of the boards are moldy and the insulation is wet. And insulation not covered is also wet.
In the winter, the roof nails are frosty.
We rerouted our plastic bathroom vents to reduce pipe runs in our attic. The west and east side of the house has open louvers for air flow. There is a power fan in the middle which runs all the time. There are no soffit vents on the house. There are a couple of vents along the middle of the roof.
Once we get the crawlspace done this summer, we want to put in new insulation in the attic in the fall.
Any suggestions to what may be causing the moisture and what can we do reducing the moisture in the attic?
Thanks in advance.
