This Old House - Season 32 Episode 19

Back in Los Angeles, host Kevin O'Connor arrives to find the new clay roof tiles on site as well as the custom windows and doors, which are made of wood and single-glazed to keep a historic look. They meet the strict California energy codes with a combination of tempered glass and Low-E coatings. Roofing contractor John Dybas returns to show Kevin the plan they've come up with for the new roof: using the roof tiles from the old house for the perimeter of the new roof only where they can be seen from the street. The rest of the field will be new, manufactured two-pan tile to cut down on costs. Down in Corona, California, Kevin sees how piles of clay and sand are mixed with water and fire to produce our roof tiles. Back in Silver Lake, John shows Kevin the polypropylene underlayment he's using, the flashing details, and how his expert crew sets the tiles along the ridges using nails, mortar, and hand tools.
