We complete our two-part interview with Ross Anderson, president of the Minnesota Building Performance Association. We discuss the myth that ventilation is a cure-all for roof and attic and ice dam issues, and discuss the real reason for these problems, which is attic air leaks (aka attic bypasses). The gang also discusses turbine vents, turtle vents, and ridge vents.

The gang also works in a jab at Bill's beloved 1.5-story homes, and Ross explains what it takes to cure ice dams on those homes for good.

You can get in touch with Ross through his company website, The Energy Network Worldwide.
