At a significant cost saving, these pre-painted metal roof panels replicate the timeless appeal of a copper patina finish, without the wait. It can take twenty years or more to achieve the beautiful patina finish on a copper roof. Meticulously designed in nine distinctive color patterns to create the many stages of rusting metal, these pre-painted “rusted” standing seam metal roof panels will instantly create an appealing vintage style.

Pre-painted “Rusted” Metal Roofing The sleek, minimalist look of weathered zinc or a vintage galvanized metal can be your new roof with these pre-painted standing seam metal roof panels featuring a durable aged metallic finish.

Pre-painted “Weathered Gray” Metal Roofing The unique appearance of bonderized metal roofing is achieved by bathing galvanized G90 steel in phosphate, and then adding a layer of chromate. Available in standing seam metal roof and corrugated metal roof panels. Also known as “Paint Grip,” the dull gray finish on this metal roof resembles weathered zinc or vintage galvanized metal, but is not a paint finish. The newest trend for metal roofs in the San Francisco Bay Area is bonderized metal roofing. Western States Metal Roofing manufacturers unique metal roofing systems, including bonderized metal roofs and metal roofing products that are pre-painted to appear as vintage rusted roofs, weathered galvanized steel roofing, dark matte, and patina copper roofs. ![]() ![]() Wedge Roofing, an award-winning metal roofing contractor, proudly installs Western States Metal Roofing Systems in Marin County, Sonoma County, San Francisco, and Napa. In addition to its stunning blue/green finish, once a copper surface's patina has had an opportunity to form completely, it is highly resistant to all forms of atmospheric corrosion, significantly improving its durability and long service life, and earning its place as the longest-lasting of all roofing materials.New Metal Roofs with Vintage Zinc, Rusted Steel, Copper Patina, or Dark Matte Finish The critical variable, in all instances, is the dwell time of moisture on exposed copper surfaces. Similarly, exposed horizontal surfaces will develop patina more rapidly than sloping surfaces, which in turn will patina more rapidly than vertical surfaces. In arid environments, the basic sulfate patina may never develop due to a lack of sufficient moisture. In rural atmospheres, where the quantity of air-born sulfur dioxide is relatively low, patina formation may not reach a dominant stage for 10 to 14 years. In industrial and seacoast atmospheres, the natural patina generally forms in five to seven years. Progressing from oxide film to sulfide film, and eventually to copper carbonate film, interference colors begin to fade and transition to relatively uniform russet brown shades. Iridescent pinks, oranges and reds, interspersed with brassy yellows, blues, greens and purples have been known to put on a stunning but albeit brief show.Īs exposure continues, the natural oxide film builds in thickness and copper's patina evolves. These surface films are so thin that depending on how light is reflected, rainbow-hued "interference colors" can be seen. These sometimes shocking color variations result from the initial formation of copper oxides. First transforming into rich browns and blacks, a copper roof will eventually take on a distinctive blue/green finish ─ a lovely reminder that this resilient metal is here to stay.ĭuring the initial weeks of copper exposure, especially in areas with a humid atmosphere or frequent rainfall, radical color changes often take place. Depending on climate conditions such as humidity, moisture and acidity, a once striking shiny metallic orange roof will slowly begin to develop its protective patina. ![]() This gradual build-up creates an extremely tough oxide-sulfate patina that works as a barrier to shield the underlying copper surface and resist all types of corrosion. The Timeless Beauty of Copper Metal RoofingĪs it ages and is subjected to various environmental conditions, copper undergoes a chemical change, coating itself with a preservative.
