As a business owner, one of the most critical decisions you'll make for your commercial building is selecting the right roofing system! Roofing not only protects your assets but also impacts your energy efficiency and overall business operations. Among the various options available, metal and TPO (Thermoplastic Polyolefin) roofs have gained a lot of popularity in recent years.

We're glad you landed here because RoofCrafters has been a name in the industry for nearly thirty years. We know that there's just as much of a decision-making process involved in commercial roofing as there is in residential roofing. And when it comes down to it- finding the right match is vital. 

In this article, we'll explore the key differences between these two roofing systems, helping you make an informed choice that suits your commercial property's specific needs and requirements. By the time you finish reading, you'll be a TPO and Metal roofing expert, which will bring you one step closer to your new roof! Let's begin. 

Putting TPO and Metal Roofing Head-to-Head

 

To get an accurate scope of how each of these roof types performs, let's do a complete overview of the benefits and stand-out details of each. By comparing both, we'll supply you with what you need to know to feel confident in your roof replacement decision. 

The Scoop on Durability 

 

Metal Roofing:

These roofs are composed of different types of metal- such as steel, aluminum, or copper. They're known for their exceptional durability and longevity, often lasting 40 to 70 years with proper maintenance. Metal roofs can withstand harsh weather conditions, including heavy rain, snow, and high winds, making them ideal for buildings in diverse climates.

TPO Roofing:

TPO roofs are single-ply membrane roofing systems made from a blend of polypropylene and ethylene-propylene rubber. These roofs are lightweight yet robust, offering excellent resistance to UV rays, ozone, and chemical exposure. TPO roofs typically have a lifespan of 20 to 30 years, making them a reliable choice for mid-term roofing solutions.

Energy Efficiency

 

Metal Roofing:

Metal roofs are known for their energy-efficient properties. They reflect a significant amount of solar heat, helping to keep your building cooler during hot summers. Metal roofs can also be coated with reflective coatings, enhancing their energy-saving capabilities. The energy efficiency of metal roofs can lead to lower cooling costs and a reduced environmental impact.

TPO Roofing:

TPO roofs are also designed with energy efficiency in mind. Their white or light-colored surface reflects sunlight, reducing heat absorption and maintaining cooler indoor temperatures. This feature can lead to noticeable savings on air conditioning costs, particularly in warm climates.

Installation and Maintenance

 

Metal Roofing:

Installing metal roofing systems requires specialized skills and expertise due to their complex design. Proper installation is crucial to avoid leaks and ensure the roof's longevity. While metal roofs are relatively low-maintenance, regular inspections and minor repairs are essential to prevent any potential issues.

TPO Roofing:

TPO roofs are relatively easier and faster to install, making them a cost-effective choice for many businesses. However, hiring an experienced roofer is essential to ensure proper installation and avoid premature failures. TPO roofs generally require minimal maintenance, making them a convenient option for busy business owners.

Environmental Impact

 

Metal Roofing:

Metal roofing is highly sustainable and eco-friendly, which is a newer area of concern for home and business owners. The majority of metal used in roofing is recycled material, and at the end of its life cycle, the roof itself is recyclable. Metal roofs contribute to reducing landfill waste and have a lower environmental impact compared to traditional roofing materials.

TPO Roofing:

TPO roofs are considered environmentally friendly due to their energy-efficient properties and reflective surface. Additionally, they are free from harmful chemicals like chlorofluorocarbons (CFCs) and halogens, making them a safer choice for the environment. However, metal roofing tops them on the sustainability scale by a longshot.

Consider the Costs 

 

Metal Roofing:

While metal roofs offer long-term cost benefits due to their durability and energy efficiency, their upfront installation cost can be higher than some other roofing materials. However, the long lifespan and low maintenance requirements of metal roofs can offset the initial investment over time.

TPO Roofing:

TPO roofs are relatively budget-friendly compared to metal roofs, making them an attractive option for businesses looking for cost-effective roofing solutions. Their moderate installation costs and energy-saving potential can lead to reasonable savings over the roof's lifespan.

Selecting the right roofing system for your commercial building requires careful consideration of various factors, including durability, energy efficiency, installation, maintenance, environmental impact, cost, and much more. Metal roofs offer exceptional longevity and energy efficiency, making them a sustainable choice in the long run. On the other hand, TPO roofs provide a cost-effective and energy-efficient solution suitable for businesses looking for mid-term roofing options.
