Other Commercial Roofing Systems

Applied Where Design, Structure, or Use Requires Alternative Systems

Other commercial roofing systems include materials such as tile and asphalt shingles, used in specific applications where building design, structure, or project requirements differ from standard commercial roofing assemblies.


Not all commercial buildings follow the same design standards.


While flat and metal systems are the most common, certain projects require alternative materials based on architectural intent, structural conditions, or specific use cases.


These systems are applied selectively—not as a default, but where they make sense within the overall project.

When Alternative Systems Are Used


Tile and asphalt systems are typically used in:


  • Mixed-use developments
  • Architectural or design-driven projects
  • Buildings with steep-slope sections
  • Properties that combine residential and commercial elements



Their use is determined by structure and design—not general application.

Tile Roofing Systems


Tile systems are used in commercial applications where:

Architectural design is a priority

Structural support allows for system weight

Long-term durability is required

They are most commonly found in projects where appearance and design continuity are part of the overall scope.

Asphalt Shingle Systems


Asphalt shingles are applied in commercial settings where:

Project scope includes residential-style structures

Budget considerations are a factor

Steep-slope design is present

They are typically used in smaller-scale commercial or mixed-use applications rather than large flat roof systems.

System Limitations


These systems are not designed for all commercial applications.


Limitations include:


  • Suitability for large-scale flat structures
  • Structural requirements (particularly for tile)
  • Performance differences compared to membrane systems


Their use is dependent on project-specific conditions.

Installation Considerations


Installation of tile and asphalt systems in commercial environments requires:


  • Alignment with structural design
  • Integration with other roofing systems
  • Proper detailing at transitions
  • Coordination with overall project scope


Execution must account for how these systems interact with the rest of the building.

Integration with Other Systems


In many cases, tile or asphalt systems are used alongside other roofing systems on the same project.


This requires:


  • Transition detailing between systems
  • Consistent water management
  • Coordination of materials and installation methods


Proper integration is critical to overall performance.

Tile and Shingle Roofing Systems Across Florida

Alternative roofing systems are installed and serviced throughout Florida, including Fort Myers, Sarasota, Tampa, Jupiter, and surrounding markets.


Application is based on project design and structural requirements.

Frequently Asked Questions

  • Are tile and asphalt commonly used in commercial roofing?

    They are used in specific applications, typically where design or structure requires them.

  • Can these systems be used on large commercial buildings?

    In most cases, no. They are more commonly used in smaller or mixed-use applications.


  • What determines whether these systems are used?

    Building design, structural support, and project requirements determine their use.

  • Can these systems be combined with others?

    Yes. They are often integrated with flat or metal systems within the same project.

  • Do they require different maintenance?

    Yes. Maintenance requirements vary depending on the system and how it is used within the building.
