S2EP113 Homegrown Hustle Winter Special: Ice Dams, Attics, and the Physics of a Broken Home

Описание: SUMMARY:
In this technically rich and practitioner-level conversation, home inspection expert Reuben Saltzman joins host Matt Eickman to dismantle common myths around ice dams, attic insulation, ventilation, and pest intrusion. Moving beyond surface-level homeowner advice, this episode explores the building science behind why homes fail in winter—highlighting how heat transfer, air leakage, disturbed insulation, and animal activity interact to create cascading structural problems. From one-and-a-half-story homes and rodent-driven thermal failures to Minnesota energy code requirements, Saltzman delivers a no-nonsense, systems-based framework for understanding—and preventing—ice dams, attic mold, and moisture damage before they become catastrophic.

KEY TAKEAWAYS:
Ice dams are caused by two conditions only: heat reaching the roof deck and snow accumulation—everything else is secondary.
One-and-a-half-story homes are inherently vulnerable to ice dams and are often cost-prohibitive to fully fix.
Air sealing—not insulation or ventilation—is the primary driver in preventing attic-related failures.
Adding insulation without air sealing can actually increase the risk of frost, mold, and ice dams.
Pest activity (especially squirrels and mice) significantly degrades insulation performance and accelerates heat loss.
Roof ventilation treats symptoms, not causes, and has minimal correlation with ice dam prevention.
Snow removal via roof raking is the only universally effective short-term ice dam prevention strategy.
Minnesota energy code legally requires air sealing before adding attic insulation—yet many contractors ignore it.
Homeowners often delay action until interior water damage appears, despite earlier warning signs.
