Kevin Corcoran from Englert Roofing systems explains to Bob benefits of the company�s environmentally friendly (56 percent recycled material), maintenance free, metal roofing product. The product applied to the project house is made of carbonized steel and carries a 50-year warranty. The exterior is bonded with aluminum and zinc then coated with a layer of acrylic. The cost is generally less than stone or tile roofs, but higher than standard shingles. Mike Worsky and Jeff Smith from Al Smith Gutters demonstrate the metal cutting and crimping machinery brought to the job site. The portable roll former transforms a flat roll of steel to the standing seam panel in the proportion on the job site. Metal roofing is now being widely distributed across the US especially in areas where wildfires are an issue as metal roofs are much harder to light and may protect your home.

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 the President of the Metal Roofing Alliance and demonstrates installation of metal roofing panels.
