In 1818 he was appointed as architect to the city of Ghent where he would realise the majority of his future projects. Gradually Roelandt moved away from the severe Empire Style in which he had been trained, and introduced more and more Neo-Renaissance and Neo-Baroque features into his designs. He also built churches in an early Gothic Revival style, such as the Sint-Annakerk in Ghent.
Among his most famous students were Louis Delacenserie and Louis van Overstraeten.
The daughter Adèle Sylvie of Lodewijk Roelandt was married to Joseph Geefs, the daughter Mathilde-Jeanne to Louis Van Overstraeten.
