The couple exchanged vows in front of their family and close friends, the singer's spokeswoman stated, according to People magazine.
The intimate ceremony, which was held at Joel's sprawling estate on Long Island, was presided over by New York Governor Andrew Cuomo, 57, a longtime friend.
Joel's daughter, singer/songwriter Alexa Ray, 29, and actor Kevin James, 50, were part of the small group of loved ones at the beautiful nuptials.
The singer, 66, and Roderick, 33, an accomplished equestrian and a former Morgan Stanley executive - have been together since 2009 and are expecting their first child, a little girl, this summer.
