What is the Best Material for a New Commercial Roof?

When it comes to installing a new commercial roof, selecting the right material is one of the most critical decisions a business owner or facility manager will face. The roof is your building’s first line of defense against the elements and plays a key role in your energy efficiency, operating costs, and long-term maintenance needs.

At Statewide Roofing, we’ve worked with commercial properties across Oklahoma for decades. From warehouses and retail spaces to restaurants and office complexes, we understand that each building has unique needs. In this post, we’ll take a close look at four of the most commonly used commercial roofing materials (PVC, EPDM, TPO, and Metal) and help you determine which might be the best fit for your project.

PVC Roofing (Polyvinyl Chloride)

PVC is a single-ply membrane made from durable plastic material. It’s particularly well-known for its chemical resistance and heat-welded seams, making it a popular option in industries where roofs are exposed to oils, grease, or fumes.

Advantages of PVC:

• Chemical and grease resistance: Ideal for restaurants, food production, and manufacturing environments.
• Heat-welded seams: Creates a watertight bond that is less prone to leaks over time.
• Fire resistance: Naturally flame-retardant and often meets high fire-safety standards.
• Energy savings: Available in light-colored options that reflect heat and help reduce cooling costs.

Things to Consider:

• PVC can be more expensive upfront than some other membrane systems.
• Over time, it may become brittle and prone to cracking if not properly maintained, especially from UV exposure.
• Like all roofing systems, quality installation is essential to ensure long-term performance and avoid seam shrinkage.
  
  

Best suited for:

Restaurants, chemical plants, commercial kitchens, and manufacturing facilities where exposure to harsh materials is a concern.

EPDM Roofing (Ethylene Propylene Diene Monomer)

Often called “rubber roofing,” EPDM has been a mainstay in commercial roofing for decades. It’s a synthetic rubber material that performs well on low-slope roofs and offers impressive longevity at a relatively low cost.

Advantages of EPDM:

• Cost-effective: One of the most affordable roofing solutions on the market.
• Durable: With proper maintenance, EPDM roofs can last 25 to 30 years.
• Flexible and weather-resistant: Performs well in fluctuating temperatures and remains pliable even in cold weather.
• Easy to repair: Small punctures or leaks can be quickly patched without replacing large sections.

Things to Consider:

• The material is more susceptible to punctures, especially on roofs with frequent foot traffic or exposure to sharp debris.
• EPDM is traditionally black, which can absorb heat and increase cooling costs. White EPDM is available but less common.
• Adhesive seams (rather than heat-welded) can degrade faster if not well-maintained.

Best suited for:

Office buildings, warehouses, and low-traffic commercial buildings that are seeking a cost-effective and reliable roofing option.

TPO Roofing (Thermoplastic Olefin)

TPO is a newer single-ply membrane that has quickly gained popularity for its combination of energy efficiency, affordability, and strength. It offers many of the same benefits as PVC, often at a lower price point.

Advantages of TPO:

• Highly reflective: TPO membranes come in white and other light colors, helping to reflect UV rays and reduce energy costs.
• Heat-welded seams: Just like PVC, these provide strong, watertight seals.
• Affordable and accessible: TPO is generally more budget-friendly than PVC while offering similar performance characteristics.
• Low maintenance: Resistant to mold growth, dirt, and debris buildup.

Things to Consider:

• Because TPO is relatively newer than EPDM or PVC, performance can vary across manufacturers.
• Some TPO membranes may not perform as well in very cold climates, becoming less flexible or more prone to shrinkage.
• The quality of installation is key. Improper heat welding or poor workmanship can significantly reduce its effectiveness.

Best suited for:

Retail stores, schools, medical facilities, and commercial buildings in warmer climates where energy efficiency and appearance are important.

Metal Roofing

While membrane systems dominate flat commercial roofs, metal roofing is a top choice for buildings with a sloped or pitched structure. Available in a variety of materials such as steel, aluminum, and zinc, metal roofs offer unparalleled durability and a sleek, modern appearance.

Advantages of Metal Roofing:

• Extremely long lifespan: A well-installed metal roof can last 40 to 70 years or more.
• Low maintenance: Requires little upkeep over time and stands up well to extreme weather.
• Fire resistant: Metal is naturally non-combustible and ideal for properties in fire-prone areas.
• Aesthetic versatility: Comes in a variety of styles, colors, and finishes to enhance curb appeal.

Things to Consider:

• Higher installation cost: While it offers long-term value, metal roofing typically has a higher upfront price than membrane options.
• Noise: Without adequate insulation, metal roofs can be loud during rain or hailstorms.
• Potential for rust: Though coatings are used to prevent it, damage to these layers can lead to corrosion over time.
• Complex installation: Requires a specialized contractor with experience in metal roofing systems.

Best suited for:

Warehouses, agricultural buildings, churches, and any commercial property with a sloped roof or a need for premium longevity and durability.

Making the Right Choice for Your Commercial Roof

Each commercial roofing material has its own strengths and its own ideal applications. Here’s a quick way to think through your decision:

• Looking for affordability and reliability? EPDM is a time-tested option with a solid track record.
• Prioritizing energy savings and modern performance? TPO might be your best bet, especially in sun-heavy regions like Oklahoma.
• Managing a restaurant or facility with chemical exposure? PVC’s resistance to fats, grease, and industrial exhaust makes it a strong choice.
• Need something that lasts for decades and boosts aesthetics? A metal roof could be the ideal long-term investment.

Ultimately, the right roofing material depends on your building type, industry needs, local climate, and budget.
