Cupolas are a great way to accent a house, barn or shed. At Plants and Things USA we have a great selection of cupolas. Made from Azek vinyl (you can also paint Azek vinyl to match) you can choose from metal, copper or asphalt shingles. Also choose if you would like to have louvers or glass windows in the cupola! We make our cupolas in America so we can do custom sizes and styles. A great rule of thumb to use is 1.25″ base size to every 1′ of unbroken roof line. When you come in to shop cupolas, know your roof pitch. Accent or accent and add a weather vain, we ssell them too. Call or come in we love to help you. The cupola can be traced back to the 8th century to add ventilation to buildings, just a fun fact.
