Jeff Smith from Al Smith Gutters demonstrates the installation of a modern metal roof panel. After sliding the panel into place stainless steel clips are installed which will allow the panel to expand and contract during its thermal cycle while still firmly adhering it to the roof underlayment. A hand crimper is then used along the entire length of the panel and finally an electric seamer seals the deal.

Bob is with Rich Melo of Newton Roofing Company for the installation of the copper roof on the Rowley addition. The 16-ounce copper panel is prefabricated with a standing seam. The cleat, or fastener, is integral to the panel and is called a Dutch seam by the manufacturer. The copper is applied on top of two layers of underlayment. There is an ice and water barrier directly on top of the decking and a slip sheet or rosin paper on top to facilitate the installation of the copper panels. Stainless steel clips are screwed into the deck every one to two feet on center, then the panels slide into clips to lock down tight. The three hips on the eave points are specially manufactured by Atas to lock into the main roof panels. The only bending done on site is for the hook at the drip edge. The metal will age over the next two to ten years, first turning a brownish bronze color, then to a green patina that will last for the lifetime of the roof. The Dutch cleat system has a crimped edge and a receiver on each panel for an interlocking design. The total cost for this small roof is between $2,500 and $3,500, depending on the copper system selected. A copper roof is inherently beautiful and durable. This roof carries a 50 year warranty, but is likely to last up to 100 years on this home.

Bob meets with Peter Merianos and the crew from Coastal Heating and Air Conditioning who are fabricating the AC ductwork on site. With the Kenmore air handler already installed in the attic, the crew begins assembling the ductwork using five-foot lengths of pre-crimped sheet-metal ducting as the basic material. The sections snap together and are secured with sheet-metal screws and foil tape. To add a new line off the main trunk, the crew cuts a hole into the the trunk with a special tool. A starting collar from which the new line will extend is then inserted into the hole. The ductwork is insulated using vinyl wrap, which is a one and a half-inch vinyl-coated fiberglass blanket.
