He also talks to a caller about attic insulation, advising that it's not always necessary to replace existing insulation, but rather to add more on top. Additionally, Gary interviews Todd Miller from Classic Metal Roofing, who shares the benefits of metal roofing, including its durability, energy efficiency, and resistance to hail and fire. They also discuss the growing trend of metal roofing and how it's becoming a popular choice for homeowners.
