The Gazebo Series cupolas are crafted using cellular pvc-vinyl or a treated yellow pine and capped with a copper or cedar roof. These make great toppers for your outback gazebo.
To determine a proper size cupola for your roof, for every foot of your building roof line use 1.25 inch of cupola. Example: For a roof section that is 24 feet, the proper size cupola would be 30 inches. For buildings longer than 48 feet, you should consider using multiple cupolas.
