Today the Zappone shingle is the best selling copper shingle in the US, and is the one most often specified by architects, contractors and homeowners. The Frank Lloyd Wright Foundation has utilized it as its copper shingle of choice, referring to it as "rich, warm and with an appearance that says 'home'". The architectural design provides an aesthetically pleasing look stylistically appropriate for nearly every building. Mr. Zappone is as particular about production as he is about design. Each shingle and accessory piece is individually crafted from top quality 99.96% pure copper or 3000 series aluminum.
