We have built a metal home with a metal roof. The attic floor has spray foam insulation over the home portion of the house. The temperature outside was 30 degrees and when it warmed up outside, their is condensation on the roof, essentially raining in the attic. How do we correct this problem?
It sounds like you have no decking beneath the roofing, correct? Do you know if the foam is closed or open cell? Are the ceilings installed yet? Is there any ventilation in the attic? What sources of moisture are inside the home that could be resulting in this?
