Rowley has appeared in several television shows and films, often portraying somewhat "ballistic" characters, especially on television shows. On the Nickelodeon television series iCarly, Rowley (as the character Lewbert) plays a mean and nasty doorman of Bushwell Plaza, where Carly, Freddie, and Spencer all live. On Carly and Sam's web show, they have a segment called "Messin' With Lewbert" where the two girls play pranks on Lewbert downstairs in the lobby of the building. On the show, Lewbert is recognized for having excessive anger outbursts (i.e., when people walk all over the floor he just mopped).
Rowley has also appeared on The Amanda Show, most notably the sketch called "Blockblister" (a parody of the video retail chain Blockbuster), where he plays a customer angered by the film he rented. He is also known as Ming on the podcast Comedy Bang! Bang!.
In 2019, Rowley worked as a writer and voice actor in the Fox series Bless the Harts, where he portrayed Jimmy Lee and Mayor Webb, with the latter role being recast in later episodes to Jon Hamm.
Rowley married Danielle Morrow in 2016, who also appeared on iCarly as Nora Dershlit in the episodes "iPsycho" and "iStill Psycho", and later the 2014 Sam & Cat episode "#SuperPsycho".[7] They have a son together.[8][9]
