24. Dorchester Triple Decker | Roof University

Kevin O'Connor joins the apprentices as they take a two-day roofing class. Then they apply their new skills on a roof at a Silva Brothers jobsite. Back at the project, a new vinyl floor goes in the top floor kitchen. Mauro Henrique touches up the first floor saved cabinets. Tom and Charlie Silva install French doors to divide the living room from a new bedroom.
