Built From the Ground Up

Founded in 1989 in Baltimore, Maryland, as Alliance Roofing and Sheet Metal, our craftsmen are some of the most awarded and prestigious in the area. Over the years, as project size grew, our scopes grew as well, and we turned over the parapet to install wall panels and punched openings. It was at that time that we realized our name needed to reflect our capabilities: the entire exterior envelope. Now we are a turnkey facade contractor specializing in all types of roofing, wall panels, and glazing.

We are Alliance Exterior Construction.

The Team Approach

Alliance has extensive experience on commercial, industrial, public, private, and public works buildings.

The key to our successful completion of these jobs is not only superior quality but also our ability to develop and maintain a team approach with the general contractors, the owners, and the architects, as well as with our own employees.
