a 1920s Saint Paul home with recurring ice dams
- Problem
- The owner of an older two-story home sees ice dams every winter and water stains on an upstairs ceiling. A previous contractor proposed new shingles.
- What we documented
- The roof has two shingle layers, no ice and water protection at the eaves, blocked soffit vents and a bathroom fan venting into the attic. The shingles themselves still have some life in them. Photos, attic observations and measurements are recorded by location.
- Outcome
- The written record shows the problem is airflow and eave protection, not just shingles. The scope includes tear-off to the deck, ice and water protection at eaves and valleys, balanced intake and exhaust ventilation, and venting the bath fan outside. The owner keeps the record either way.
