Choosing the right roofing system for your commercial property in Oklahoma is a big decision. With intense heat, high winds, hailstorms, and even tornadoes, businesses need a roof that is durable, energy-efficient, and cost-effective. Two of the most popular options for commercial roofing are TPO (Thermoplastic Olefin) roofing and metal roofing—but which one is best for your business?
In this guide, we’ll break down the pros, cons, costs, and performance of each option to help you make an informed decision.
What Is TPO Roofing?
TPO (Thermoplastic Olefin) is a single-ply roofing membrane commonly used on flat and low-slope commercial roofs. It is made from rubber and synthetic materials, which are designed to be flexible, durable, and resistant to weather damage. TPO is installed by rolling out large sheets and heat-welding the seams to create a watertight seal.
Pros of TPO Roofing for Oklahoma Businesses
✔️ Energy Efficiency – TPO roofs are typically white or light-colored, reflecting the sun’s heat instead of absorbing it. This helps lower cooling costs during Oklahoma’s hot summers.
✔️ Cost-Effective – Compared to metal roofing, TPO is more affordable upfront, making it a great choice for businesses on a budget.
✔️ Resistant to UV Rays & Chemicals – Oklahoma gets a lot of direct sunlight, but TPO roofing is designed to resist UV damage, preventing premature aging. It also holds up well against exposure to chemicals, grease, and oil, making it ideal for restaurants or industrial facilities.
✔️ Flexibility & Lightweight – Because TPO is lightweight and flexible, it’s a great option for buildings with weight restrictions. It also expands and contracts with temperature changes, reducing the risk of cracking.
✔️ Easy Installation & Low Maintenance – TPO comes in large sheets, which speeds up installation. Once installed, it requires minimal maintenance, as it resists mold, dirt buildup, and punctures.
Cons of TPO Roofing
❌ Shorter Lifespan Compared to Metal – While TPO lasts around 15-30 years, metal roofs can last 40+ years with proper care.
❌ Seams Can Be a Weak Point – Although heat-welded seams are strong, if not properly installed, they can be prone to leaks over time.
❌ Vulnerable to High Winds & Impact – Oklahoma’s severe weather, including tornadoes and hail, can cause damage to TPO membranes, leading to tears and punctures.
What Is Metal Roofing?
Metal roofing is another popular choice for commercial and industrial buildings. It consists of steel, aluminum, or copper panels that are either screwed down (exposed fastener) or installed with a hidden locking system (standing seam). Metal roofing is known for its durability, longevity, and ability to withstand harsh weather conditions.
Pros of Metal Roofing for Oklahoma Businesses
✔️ Extreme Durability & Longevity – Metal roofing can last 40-70 years, making it a long-term investment for business owners. It can withstand hail, high winds, and heavy rain, making it ideal for Oklahoma’s unpredictable weather.
✔️ Fire & Wind Resistant – Metal is naturally fire-resistant, which adds an extra layer of protection. Plus, metal roofs hold up better in high-wind events compared to TPO.
✔️ Minimal Maintenance – Unlike TPO, metal roofs don’t require frequent repairs or inspections. They resist mold, rot, and insect infestations.
✔️ Energy Efficient with Proper Coatings – Although metal absorbs heat, businesses can opt for cool roof coatings that reflect sunlight and reduce energy costs. Some metal roofs are even ENERGY STAR® rated.
✔️ Eco-Friendly & Recyclable – Many metal roofs are made from recycled materials and can be recycled at the end of their lifespan, reducing waste.
Cons of Metal Roofing
❌ Higher Upfront Cost – Metal roofing is more expensive than TPO initially, but its long lifespan can make it more cost-effective over time.
❌ Noise During Storms – Metal roofs can be noisy during heavy rain or hail unless proper insulation is installed.
❌ Prone to Dents from Hail – Oklahoma’s hailstorms can cause dents and cosmetic damage to metal roofing, though certain types (like thicker steel panels) resist impact better.
Cost Comparison: TPO vs. Metal Roofing
One of the biggest deciding factors for businesses is cost. Here’s how TPO and metal roofing compare:
| Roof Type | Average Cost per Sq. Ft. Installed | Lifespan |
| TPO Roofing | $5 – $10 per sq. ft. | 15 – 30 years |
| Metal Roofing | $10 – $20 per sq. ft. | 40 – 70 years |
Key Takeaway: While TPO is cheaper upfront, metal roofing provides better long-term value due to its durability and longevity.
Which Roofing Type Is Best for Oklahoma Businesses?
Choose TPO Roofing If:
✅ You have a flat or low-slope roof
✅ You need a budget-friendly solution
✅ You want an energy-efficient, reflective roof to lower cooling costs
✅ Your business is in a low-risk storm area
Choose Metal Roofing If:
✅ You need maximum durability against Oklahoma’s hail, wind, and storms
✅ You want a roof that lasts 40+ years with minimal maintenance
✅ Your business is in a high-wind or tornado-prone area
✅ You’re looking for a long-term investment rather than the cheapest option
Final Thoughts: TPO vs Metal Roofing for Oklahoma Businesses
Both TPO and metal roofing offer great benefits, but the best choice depends on your budget, location, and long-term goals.
- For cost-conscious businesses, TPO is a great short-term solution that provides energy efficiency and flexibility.
- For long-term durability and weather resistance, metal roofing is the best investment—especially for businesses in storm-prone areas of Oklahoma.
