Walmart Expansion – Tucson Roofing Project
Single Ply Roofing Experts completed a full roof demolition and re-roof for the 112,800-square-foot Walmart expansion project in Tucson, AZ. The large-scale retail project required organized tear-off, installation across an expansive low-slope roof, and careful detailing around rooftop equipment, penetrations, drainage areas, and perimeter conditions.

Overview
112,800 Sq. Ft. Commercial Re-Roof for a Walmart Expansion in Tucson, AZ
At 112,800 square feet, this Walmart expansion in Tucson was a roofing project where scale changed everything.
Single Ply Roofing Experts completed a full roof demolition and commercial re-roof, working across an expansive retail property with numerous rooftop units, penetrations, transitions, drainage points, and perimeter conditions.
A roof of this size is not simply one large surface. Every mechanical unit, curb, drain, penetration, edge, and change in elevation becomes part of the overall roofing system. Maintaining consistency across more than 100,000 square feet while giving those smaller details the attention they require demands a disciplined approach to demolition and installation.
The Tucson location adds another consideration. Commercial roofs in southern Arizona experience prolonged sun exposure, high temperatures, and seasonal weather events, making roof condition and long-term system performance especially important for large properties.
For retailers, developers, general contractors, and commercial property owners, the Walmart expansion demonstrates the level of coordination required for a large-scale commercial roof replacement in Tucson, Arizona.

The challenge
The larger the commercial roof, the more important consistency becomes. Across the Walmart expansion, approximately 112,800 square feet of roofing had to be addressed while accounting for the numerous conditions spread throughout a large retail building. Aerial photography shows rooftop equipment positioned throughout the property, along with penetrations, multiple drainage locations, perimeter edges, and construction activity associated with the expansion. Each of those areas introduces details that must be considered during demolition and re-roofing. The sheer scale also affects project logistics. Removing an existing commercial roof generates a substantial volume of material. New roofing materials have to be staged and moved efficiently. Work areas need to progress in a controlled sequence, and exposed sections of the building have to be carefully managed as demolition gives way to installation. On top of that, Tucson's intense solar exposure means a commercial roof spends much of its service life in demanding environmental conditions. The challenge was therefore bigger than replacing an aging roofing surface. It was managing 112,800 square feet of commercial re-roofing as one coordinated project without losing sight of the individual details that influence long-term performance.
The solution
Single Ply Roofing Experts completed the Walmart expansion through a coordinated full roof demolition and re-roof process, addressing the building systematically rather than treating its massive roof area as one uninterrupted surface. Existing roofing materials were removed, allowing the project to move into the installation phase across the approximately 112,800-square-foot roof area. The new roofing work was coordinated around the building's rooftop equipment, penetrations, drainage locations, edges, and transitions. Open roof fields required consistent installation across large areas, while equipment-heavy sections demanded more concentrated detailing. This combination of large-scale production and detail-focused roofing is particularly important on retail properties. The broad roof field may dominate an aerial view, but long-term roof performance also depends on how carefully the system is integrated at its penetrations, drains, curbs, transitions, and perimeter conditions. The finished project provides the Tucson property with a renewed commercial roofing system while demonstrating Single Ply Roofing Experts' ability to manage large commercial flat roofing projects in Arizona. For commercial property owners, retail operators, developers, and facility teams evaluating an aging roof, the first step is understanding whether targeted repairs still make sense or whether the building is ready for a comprehensive replacement.
