When it comes to protecting a commercial building, the roof is one of the most important investments you’ll make. This FAQ section is designed to give clear answers to the questions business owners and property managers in Greenville ask most often.

Materials & Types of Commercial Roofs

Q: There are so many options. How do I choose a roofing material?

A: The best choice depends on your building’s design, roof slope, deck type, and budget. Most commercial properties use systems designed for flat or low-slope roofs. A roofing professional can help match your building’s needs with the right materials for performance, durability, and long-term value.

Q: What are the most common materials for commercial roofs?

A: Most commercial buildings in Greenville have flat or low-slope roofs, and a few systems are used most often:

• Single-Ply Membranes: Flexible sheets like TPO, PVC, EPDM, or KEE. Popular for durability, cost-effectiveness, and energy efficiency.

• Asphalt-Based Roofs: Built-up roofing (BUR) and modified bitumen use layers of asphalt and reinforcement for long-lasting protection.

• Metal Roofing: Steel, aluminum, or other metals, known for longevity and clean appearance.

• Other materials — shingles, coatings, slate, copper, or tile — are used less frequently due to cost, maintenance, or suitability for flat or low-slope roofs.

Q: Which roofing systems are most energy-efficient or sustainable?

A: TPO and PVC membranes reflect sunlight to reduce cooling costs, metal roofs can be recycled, and green roofs add insulation while managing stormwater. A roofing professional can help balance sustainability goals with material selection.

Q: How long can I expect a commercial roof to last?

A: Lifespan varies by material and maintenance. Single-ply membranes: 20–30 years; asphalt-based systems: 15–25 years; metal roofs: 40+ years. Regular inspections and upkeep extend the life of any roof.
