In his bid for a third term as mayor in the primary election on November 4, 2014, Roy faced Jamar Gailes, Jeff Hall, Mitzi "Gibson" LaSalle, and Nicholas R. P.

[1] Roy was considered a potential Democratic candidate in 2016 for the United States Senate seat vacated by Republican David Vitter, who failed in a bid for governor in 2015.

[2] On November 8, 2022, Roy was elected Mayor of the City of Alexandria gaining 51% of the vote against his multiple opponents including Jeff Hall the incumbent candidate.

[10] Roy created the program Diversity in Action,[11] which significantly increased the number of small, emerging, minority, and women-owned businesses in Alexandria.

He co-chaired Louisiana's first World Cultural Economic Forum, which was spearheaded by then Lieutenant Governor Mitch Landrieu, the mayor of New Orleans.

[4] Jeff Hall, who lost to Roy in 2014 and the next year became a state representative, again ran for mayor on "a pro-business, pro-people platform that brings jobs back, grows existing businesses, and makes city government something that actually works.
