Attic Condensation in Idaho

Condensation in the attic can rot roof decking and reduce shingle life. It often shows up as frost, damp insulation, or musty smells.

Common causes

• Bathroom/kitchen vents exhausting into the attic.
• Air leaks from the home into the attic.
• Insufficient ventilation (intake or exhaust).

What to do

Start with identifying moisture sources, then correct ventilation and air sealing. A roof inspection can help determine whether the issue is ventilation, flashing, or both.
