The Bedford House: Insulation, Roofing

General contractor Tom Silva tops off the existing cellulose insulation in the walls of the oldest part of the house. Meanwhile, landscape contractor Roger Cook takes homeowner Becky Titlow to see a display of "garden to table" raised beds at Elm Bank Reservation in Wellesley, MA. Then, back at the house, landscape designer Jenn Nawada lends a hand as Roger builds raised beds out of fieldstone from the old foundation, and Becky plants the first vegetables for her family. On the roof of the new addition, Tom shows host Kevin O'Connor how he's using a self-sealing membrane on the low slope roof, and at the drip edge, to properly waterproof the roof.
