At Annapolis Weathervanes, we complete the look of your roof, cabin, shed, and barn with an elegant cupola. It’s the best way to enhance the aesthetics of your property. Cupolas are actually really cool – they act like a set of louvers installed on your roof so that the air can enter while keeping any unwanted moisture out. It keeps the attic free from rot, mold, or mildew. It also helps with airflow and ventilation, which is super useful.
