Selecting the right roof for your building isn’t just about covering a structure—it’s about long-term protection, energy savings, and peace of mind. For business owners, this decision influences safety, costs, and even how comfortable a building feels day to day. With so many options available, it can feel overwhelming to know which material or system to trust. That’s why understanding the differences between today’s leading commercial roofing systems is essential before making the investment.
Below, we’ll walk through the most popular roofing options, how to compare them, and what you should consider when deciding which solution best fits your business needs.
What material is used for commercial roofing?
Commercial roofing today is no longer limited to one or two materials. Businesses can choose from single-ply membranes like TPO, PVC, or EPDM, durable metal systems, or asphalt-based options such as modified bitumen and built-up roofing. Each material has unique strengths depending on your building’s location, design, and functional needs.
Some business owners even consider foam roofing, which creates a seamless insulated surface that performs well in energy-intensive buildings. Choosing among these business roof options comes down to balancing budget, maintenance, and long-term performance.
What are the top 5 roofing materials?
While many materials exist, five stand out as the most widely used:
- TPO (Thermoplastic Polyolefin) – A white reflective single-ply membrane that resists UV rays and lowers cooling costs.
- PVC (Polyvinyl Chloride) – A plastic-based membrane highly resistant to chemicals, making it great for restaurants and facilities with grease exposure.
- EPDM (Ethylene Propylene Diene Monomer) – A black rubber membrane, long-lasting and highly resistant to weathering.
- Metal Roofing – Steel, aluminum, or copper systems that can last over 50 years with minimal upkeep.
- Modified Bitumen (Modbit) – Asphalt-based, flexible, and easy to install, often torch-applied for watertight seams.
These five cover nearly all commercial flat and low-slope roofing needs. However, don’t overlook options like foam roofing and built-up roofing (BUR), which continue to serve businesses well.
TPO: Energy Efficiency and Reliability
TPO has surged in popularity because of its balance of affordability and performance. Its white reflective surface makes it ideal for lowering cooling costs in warm months, and it’s resistant to UV rays, ozone, and chemicals. TPO can be mechanically attached or fully adhered, giving flexibility in installation.
The main consideration with TPO is maintenance—its bright white surface gets dirty faster, reminding business owners to schedule regular cleanings and inspections. Still, for many, its efficiency and 20–25 year lifespan make it an excellent choice.
EPDM: Longevity at a Lower Cost
If durability and cost-effectiveness are priorities, EPDM is one of the strongest contenders. Known as “rubber roofing,” EPDM membranes resist heat, cold, and UV radiation while lasting 25–30 years or more. Large sheets reduce seams, lowering the chance of leaks.
Because it is typically black, EPDM absorbs more heat, which can increase cooling costs in warmer climates. However, in colder regions, that heat absorption can be a benefit. Its resilience and affordability keep it among the most installed commercial roofing systems in the country.
Metal Roofing: The Long-Term Investment
For businesses looking for decades of performance, metal roofing is hard to beat. Whether steel, aluminum, or copper, these systems can last 50–70 years with minimal upkeep. Metal is fire-resistant, sheds snow easily, and withstands extreme weather conditions.
While the upfront cost is higher, the long lifespan and low maintenance requirements make metal roofing a cost-effective choice in the long run. For businesses weighing flat vs metal roof choices, metal is often selected for sloped structures where aesthetics and durability align.
Modified Bitumen and BUR: Proven Asphalt Systems
Modified Bitumen (Modbit) combines traditional asphalt with polymer binders, offering flexibility, strength, and easy installation. Often applied with a torch (sometimes referred to as “torch down roofing”), Modbit creates watertight seams and can be finished with granular or smooth surfaces.
Built-Up Roofing (BUR), or “tar and gravel” roofing, has been used for over a century. Multiple layers of asphalt and reinforcing materials provide strength and weather resistance. While heavier than other systems, BUR remains one of the most cost-effective and durable flat roof options.
Foam Roofing: Seamless and Insulated
Foam roofing, though less common, is an innovative solution. Sprayed as a liquid, it expands into a durable foam layer that hardens into a seamless surface. Its insulating properties lower energy costs, and its lightweight structure reduces stress on the building.
Foam roofing typically lasts 30 years with recoating, making it attractive for owners who want both insulation and ease of repair. It’s especially popular in areas with high energy costs.
What is the best material for commercial roofing?

The “best” material depends on what your business values most:
- For energy efficiency, TPO and PVC stand out.
- For cost-effectiveness, EPDM and Modbit remain excellent choices.
- For longevity, metal roofing is unmatched.
- For chemical resistance, PVC is ideal.
- For insulation, foam roofing provides unique advantages.
Each material carries trade-offs, which is why weighing budget, climate, and building function is key. Many business owners also refer to resources like the Roofing Material Guide by Malick Brothers Exteriors for additional insights before making a final decision.
Which roofing system is most used for commercial buildings?
Single-ply membranes, especially TPO and EPDM, are currently the most common. Their affordability, ease of installation, and proven performance make them dominant choices in the industry. Metal is also widely used for sloped commercial roofs, particularly in warehouses and industrial settings.
Still, “most common” doesn’t always mean “best.” For businesses that want decades of use with minimal replacement costs, metal may outshine. For restaurants exposed to chemicals, PVC makes more sense. The most used system varies depending on industry, region, and budget.
Corporate Considerations for Business Roof Options
Beyond material, businesses must also evaluate their roofing contractor. Choosing a reputable local roofer ensures knowledge of local climate and building codes. Contractors should have experience with the specific material you select, whether it’s a flat membrane or a metal roof system.
Good communication and warranty management are also essential. Commercial roofs often come with multiple manufacturer warranties, and a trusted contractor can manage these on your behalf. Many also offer maintenance plans, giving you peace of mind knowing inspections and repairs are handled on schedule.

Final Thoughts: Making the Right Choice
Deciding how to choose the right commercial roofing system for your business is no small task. Every option—TPO, PVC, EPDM, metal, Modbit, BUR, or foam—has its benefits and trade-offs. What matters is aligning your roof choice with your building’s needs, budget, and long-term goals.
The best step forward is to get multiple estimates from trusted local contractors and compare both material options and service approaches.
