If you’re already stressing about ice dams, I’d be careful with anything that adds layers or complexity up there. Have you checked if your attic’s ventilation is up to par? Sometimes it’s not just about insulation or the roof type—poor airflow can make leaks and ice dams way worse.
- Ventilation’s important, but it’s not always the main culprit.
- I’ve seen plenty of ice dams on roofs with “perfect” airflow—sometimes it’s just lousy insulation or weird roof angles trapping heat.
- Adding a layer (like ice & water shield) can actually help if you’re in a spot that gets hammered by freeze-thaw cycles.
- Just don’t overdo it and block soffit vents... seen that mistake too many times.
- Every house is different—sometimes you gotta try a combo of fixes, not just focus on one thing.
