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.
