Understanding Flat Roofing Systems for Commercial Properties
If you’re exploring flat roofing systems, you’re likely evaluating different options to protect your commercial building. Flat roofs are common in commercial construction thanks to their clean look, practical layout, and cost-effective design. But not all flat roofing materials are created equal, and the right one depends on your business, building structure, and budget.
At Luna Siding and Roofing Inc., we guide business owners through the many
types of commercial roofing to help them make confident, informed choices.
Popular Flat Roofing Systems for Commercial Buildings
Built-Up Roofing (BUR)
Built-Up Roofing is a classic system made by layering asphalt and felt or fabric. These layers form a durable, waterproof surface topped with gravel for added protection.
This option is ideal for businesses looking for:
- Strong protection against foot traffic
- A time-tested, reliable material
- Better insulation
However, BUR systems can be heavier and require longer installation times, so they’re best for buildings designed to support added weight.
Modified Bitumen
Modified bitumen systems are similar to BUR but offer more flexibility. They consist of a single-ply membrane that’s reinforced with polymers for better elasticity and performance.
These are often chosen for:
- Small to medium-sized buildings
- Simpler, faster installation
- Moderate foot traffic areas

TPO and PVC Membranes
TPO (thermoplastic polyolefin) and PVC (polyvinyl chloride) are single-ply membranes known for energy efficiency and heat reflection.
They’re great choices if you want:
- Lightweight roofing with high UV resistance
- Lower energy bills
- Seamless installation and fewer leaks

Is a Flat Roofing System Right for Your Business?
Climate and Drainage Considerations
Flat roofs are well-suited for areas with light to moderate rainfall. They require carefully designed drainage systems to prevent pooling. Businesses in Warwick, for instance, should consider seasonal precipitation and snow loads when selecting roofing materials.
Building Use and Equipment
Flat roofs are popular in commercial buildings because they support HVAC systems, solar panels, and even rooftop patios. The system you choose should align with how the space will be used.

Common Benefits of Flat Roofing Systems
Flat commercial roofs offer several business-friendly benefits:
- More usable rooftop space
- Lower material costs compared to pitched roofs
- Easier, safer access for inspections and maintenance
That said, routine care is essential. Drainage issues or neglect can lead to leaks and structural damage over time. That’s why choosing a trusted installer makes all the difference.
