What is a Commercial Roofing System?
The roofing structure for a commercial building consists of diverse materials and specialized design methods. We custom-engineer these installations to suit the exceptional needs of large-scale buildings.
Note: This post was originally published in March 2024 and has been fully updated in 2026.
Unlike residential roofs, commercial systems are generally vast. They are exposed to unique stressors like heavy foot traffic, specialized equipment installations, and complex HVAC systems.
We engineer these systems to ensure your commercial properties remain secure against the elements while maximizing energy efficiency and structural longevity.
In this guide, you will learn about the most effective commercial roofing types and the importance of choosing materials that fit your specific property needs.
Common Types of Commercial Roof Styles
Flat Roof
A flat roof is one of the most preferred variants for Oklahoma commercial structures due to its concise design and versatility.
Key benefits of flat roofs include:
- HVAC Integration: Easy placement of heavy cooling units.
- Solar Readiness: Ideal for modern 2026 solar array installations.
- Green Roofing: Simple to adapt into sustainable “living” roofs.
Efficient water drainage remains essential to avoid uncontrolled water accumulation and leaks.
Gable Roof
Gable roofs feature a classic triangle shape with slanting sides. We often use these for industrial properties that require extra clearance.
They offer excellent attic space, superior water runoff, and natural ventilation.
The best part about a gable roof? It tolerates almost any roofing material, from asphalt shingles to metal panels, ensuring high durability.
Butterfly Roof
Butterfly roofs differ from traditional styles because they curve upward. This creates a striking, modern architectural appearance.
Businesses with butterfly roofs typically use the central valley for rainwater harvesting. It is a practical and sustainable solution for eco-conscious brands.
Hip Roof
A hip roof features sloped sides on all four sides that meet at a central ridge.
The hip roof is exceptionally stable. It resists strong Oklahoma winds and provides a drainage system perfectly suited for areas with heavy rainfall.
Gambrel Roof
Gambrel roofs have two slopes on each side. This gives them a distinct barn-like appearance that maximizes interior volume.
We often recommend these when you need additional space for warehouse storage or want to improve the aesthetic character of a building.
Mansard Roof
Mansard roofs are recognized by their four-sided double slopes. They are inspired by classic French architecture.
The upper levels of these structures serve as excellent additional storage or office space. They significantly boost the curb appeal of high-end commercial properties.
Shed Roof
Shed roofs consist of a single sloping flat plane attached to a taller wall.
These designs are simple, affordable, and highly effective at diverting water. We see shed roofs most commonly in contemporary industrial designs today.
Types of Commercial Roof Materials
Commercial Shingle Roofing Systems
Shingle roofing is no longer just for homes. In 2026, many businesses are choosing shingles for their versatility and cost-effectiveness.
Commercial shingle roofs are available in:
- Asphalt
- Wood
- Fiberglass
- Advanced Composites
These systems are known for fast installation. We recommend them for businesses that need a quick, high-quality solution without major operational interruptions.
Key Takeaway: Modern shingles are engineered to withstand severe Oklahoma weather, including 100+ mph winds and heavy sun exposure.
Commercial TPO Roofing Systems
Thermoplastic Polyolefin (TPO) membranes are currently the gold standard in the commercial sector. They offer a balance of performance and energy efficiency.
TPO roofs reflect sunlight to prevent heat absorption. This significantly decreases cooling costs and increases the energy efficiency of your building.
They offer remarkable seam strength, making them the perfect choice for the large, flat surfaces typical of industrial rooftops. TPO remains highly resistant to UV rays and chemical exposure.
Commercial Metal Roofing Systems
Metal roofing provides top-tier protection from Oklahoma’s extreme climate, including heavy rain, hail, and snow.
Metal roofing is famous for its longevity. In fact, many metal roofs now last 50 to 70 years with regular maintenance. Metal is resistant to fire, rot, and insects. It is also highly reflective, which helps reduce solar radiation and lowers monthly cooling expenses.
Commercial EPDM Roofing Systems
EPDM membranes (rubber roofing) are a durable choice for flat or low-slope systems.
These chemically compounded membranes expand and contract with temperature changes. This flexibility prevents cracking during Oklahoma’s intense thermal shifts.
Key Takeaway: EPDM roofs provide a watertight barrier that is easy to repair. Localized damage can be fixed quickly and efficiently without replacing the entire system.
Commercial Modified Bitumen Roofing Systems
Modified Bitumen is a preferred option for low-slope roofs due to its multi-layered protection.
We use polymer-modified technology to give these roofs enhanced strength and flexibility. They are specifically designed for high-traffic areas where durability is the priority.
Modified bitumen membranes offer excellent waterproofing and thermal shock resistance. Because even small water leaks can cause massive damage in large buildings, this material is a smart investment to avoid long-term repair costs.
Commercial Tile & Slate Roofing Systems
Commercial Tile & Slate Roofing Systems are known for their traditional beauty, strength and premium look.
These systems use clay, concrete, or natural stone to create a roof that can last over 50 years. They are naturally resistant to fire, pests, and rotting.
While the initial investment is higher, the curb appeal and extreme lifespan make it a cost-effective long-term solution for high-end retail or corporate offices.
Commercial Roof Coatings
Roof coatings are a proactive way to extend the life of an existing roof. We apply these directly to the surface to form a seamless, waterproof membrane.
In 2026, modern coatings offer:
- UV Protection: Shields the roof from sun damage.
- Thermal Stress Reduction: Prevents expansion/contraction damage.
- Cost Savings: An affordable alternative to a full roof replacement.
Coatings are versatile and work well on metal, asphalt, EPDM, and TPO surfaces.
Commercial BUR Roofing Systems
Commercial Built-Up Roofing (BUR) Systems, also known as asphalt and gravel roofs, are a time-tested and reliable choice mostly for flat or low-slope commercial roofs.
BUR consists of multiple layers of bitumen and saturated felts. This creates a dense, thick barrier that is incredibly resilient against foot traffic and heavy hail.
We can customize the number of layers in your BUR system to meet specific waterproofing needs. It remains one of the most reliable and fire-resistant options available for heavy-duty industrial applications.
