What your attic does to that number in Springdale
| Attic | Dam days | Risk |

| Typical, some insulation, not air-sealed | 6.8 | Moderate |
| Older or poorly insulated, warm attic | 10.1 | Moderate |

What to do about ice dams in Springdale
- Air-seal the attic floor: the gaps around the hatch, light fixtures, plumbing stacks and the top plates of interior walls. This is the fix that removes the cause, and it usually costs less than a season of contractor ice removal.
Which to spend on first: air sealing or heat cable.
