What is, Commercial Flat Roofing?

Flat roofing refers to a roofing design with a low slope, commonly used on commercial and industrial buildings. Unlike pitched roofs, flat roofs maximize usable space and allow for the installation of HVAC units, solar panels, or rooftop gardens. Flat roofing systems—such as EPDM rubber, TPO, and modified bitumen—are engineered for strength, energy efficiency, and ease of maintenance, making them ideal for commercial properties across Queens and Long Island.
