Please note that Royal Crowne cupolas are AZEK cupolas which makes them the most maintenance free cupola ever!!
Sundance Cupola Roof Pitch: The Sundance series of cupolas will support a roof pitch of 6/12 in its standard form right out of the box. If you have a steeper roof pitch then you need to also order a base extension. Adding a single base extension will make the Sundance cupola compatible with up to a 12/12 pitch roof. For roof pitches greater than 12/12, please contact us directly for a complimentary roof pitch and base extension consultation.
