Flat Roof Systems, Commercial & Industrial

Flat and low-slope roof systems are the go-to solution for commercial and industrial buildings. Their wide-span design offers practical, cost-effective coverage for large properties while simplifying inspections, repairs, and system upgrades.

With over 135 years of experience, Highland Roofing is Louisville’s trusted expert in commercial flat roofing. Our certified crews deliver high-quality installation and service with integrity, safety, and unmatched attention to detail.

What Are Flat Roof Systems?

Flat roofing systems are designed with little or no pitch, allowing for broad surface coverage while maintaining proper drainage through slight slopes. This makes them ideal for commercial properties like warehouses, schools, hospitals, and retail centers.

Flat and low-slope roofs offer key benefits for large buildings:

  • Cost-effective materials and installation
  • Simplified access for rooftop units and maintenance
  • Streamlined drainage and insulation
  • Greater flexibility in roofing system selection

Types of Flat Roof Systems

At Highland Roofing, we offer a full range of flat roof systems to suit your building type, performance needs, and budget.

Single-Ply Roofing

TPO, PVC, and EPDM membranes are lightweight, durable, and energy-efficient. These systems provide excellent resistance to UV exposure, chemicals, and weather, making them a popular choice for modern commercial facilities.

Modified Bitumen

This asphalt-based system combines strength and flexibility, with multiple application methods: torch-applied, cold adhesive, or self-adhered and is suited for buildings that need robust waterproofing and resilience in
extreme temperatures.

Built-Up Roofing (BUR)

BUR systems use multiple layers of asphalt and reinforced fiberglass felts to create a long-lasting, waterproof barrier. Known for their reliability, BUR roofs are ideal for high-traffic commercial roofs that demand long-term performance.

Metal Roofing (Low-Slope)

Standing seam and other low-slope metal options offer durability, lightweight construction, and excellent lifespan. Metal systems are often used on buildings with complex layouts or partial low-slope areas.

Benefits of Flat Roof Systems

Flat and low-slope roofs provide a wide range of advantages for commercial and industrial buildings:

  • Maximized building space for HVAC systems, solar panels, or storage
  • Easier access for inspections, repairs, and routine maintenance
  • Improved energy efficiency through reflective membranes and insulation
  • Multiple system types to meet specific building and budget requirements
