What it is: Ridges of ice at the eaves that back meltwater up under the shingles.
Why it matters
Ice dams force water into the attic and walls, causing rot, staining and mold.
Why it's common in Bloomington
A signature Minnesota/Bloomington winter defect, driven by attic heat loss and poor ventilation.
Signs to watch for
- icicles and ice ridges at eaves
- interior ceiling/wall stains
- wet attic insulation
What we check during the inspection
We look for staining and check attic insulation/ventilation for the underlying cause.
How it's typically corrected
Air-seal and insulate the attic floor and improve ventilation; manage snow load.
