If you want to add some style to your rooftop, you can install a weathervane cupola on it. A weathervane cupola is a weathervane mounted on a cupola, rather than on the bare roof gable. This combination gives your weathervane some height, and enhances its looks. A cupola, besides providing an accent, can also serve as a vent for warm and moist air, discouraging the growth of molds and mildew. Some cupolas have tiny louvers that keep the snow out, but allow light and air to pass through. Some even have windows. The cupola can be made of wood, aluminum, fiberglass or copper; or the entire setup can be made of hand carved copper, which looks great even when weathered.
