Ice dam risk in Taylor, MI

What your attic does to that number in Taylor
| Attic | Dam days | Risk |
|---|---|---|
| Air-sealed and well insulated | 7.0 | Moderate |
| Typical, some insulation, not air-sealed | 14.1 | Moderate |
| Older or poorly insulated, warm attic | 22.9 | High |
Sealing and insulating a typical attic takes out about 7.1 days a winter here. It does not move the risk band, but it shortens every dam. An older house with a warm attic should expect closer to 22.9 days.
What to do about ice dams in Taylor
- 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.
- Rake the bottom three or four feet of roof after any storm that leaves more than about six inches, from the ground with a roof rake.
Which to spend on first: air sealing or heat cable.
