This Windsor vinyl cupola is built using an innovative material that is even more durable and rugged than natural wood. These vinyl cupolas are constructed from solid white PVC. The high-quality vinyl construction makes these cupolas extremely durable, weather resistant, and virtually maintenance free. They are unaffected by rain, snow, humidity, salt air, or pesky insects. They don't need painting, but can be easily painted to complement any structure. Our new Maintenance Free Vinyl Cupolas are available in a variety of designs and sizes. They are made of solid PVC and most feature copper rooftops, windows or louvers and shiplap or smooth bases. The correct cupola size is derived from the measurement of the roof's ridge.
