Types of commercial flat roofs range from thermoplastic to metal to gravel, but they all have one thing in common—every commercial flat roof needs a carefully engineered support system. Supporting the roof of a large commercial building takes both building and engineering expertise. When you need a design-build firm for a new build or structural repairs, you can rely on The Structures Group in Phoenix.

Commercial Flat Roof Types

Steel Roof Systems

Many large commercial buildings utilize the strength of a steel-framed roof structure. Steel joists are one of the most common types of commercial flat roof supports. The immense strength of steel allows it to span great distances, support heavy loads, and withstand both strain and tension. 

Wood Roof Systems

The exceptional strength of long-span glued, laminated beams and girders allows them to cross great distances and sustain heavy loads. Glulam beams and purlins offer both strength and architectural elegance, which makes them ideal for large commercial flat roof buildings. They can be customized to fit any flat roof shape or size.

Composite Roof Systems

Roof structures built from a combination of wood and steel unite the strengths of both materials. Composite roofs often present the most economical option for large, commercial flat roof structures. At The Structures Group, we ensure that you get the most cost-effective flat roof system for your build.

Panelized Roof Systems

The Structures Group specializes in panelized wood roof construction, a revolutionary new method that saves both time and labor. This method speeds up construction times and minimizes risks to builders because the roof sections are built on the ground and then lifted into place with a forklift. 

Advantages of Design-Build Construction

Building a large-scale, commercial flat roof structure requires a diverse team of architects, engineers, developers, and contractors. Hiring a design-build firm to coordinate every aspect of construction will save you both time and money. Spend less on materials, labor costs, and construction time by working with a design-build contractor.
