Key points
- Ice dams form when heat escapes into the attic and melts snow on the roof.
- Meltwater backs up under shingles and wets the roof deck and insulation.
- Mold can grow quietly on sheathing and show up months later.
- Air sealing and ventilation fix the cause.
Signs after winter
- Dark staining on attic sheathing or rafters
- Damp or compressed insulation
- Ceiling stains along exterior walls
- Musty smell upstairs in spring
What to do
- Have the attic inspected — see mold in attics
- Fix air leaks and ventilation — see ice dam prevention and bath fan venting
- Replace wet insulation — see wet insulation
