Types of Commercial Roofing Explained: Pros, Cons, and Best Uses

When it comes to commercial roofing, the right choice can make all the difference. 

Whether you're looking to reduce energy costs, improve durability, or manage your budget effectively, selecting the right roofing system for your property is critical. 

The roof is one of the most essential parts of any commercial building, protecting it from the elements and contributing to energy efficiency and overall performance.

With so many options available, understanding the types of commercial roofing and their best uses can help you make a decision that fits your needs.

In this blog, we’ll explore the best types of roofing materials by breaking down the pros, cons, and ideal applications of each option.

Built-Up Roofing (BUR)

Built-Up Roofing (BUR) is one of the oldest and most reliable roofing systems for commercial properties. 

This multi-layered system consists of alternating layers of bitumen and reinforcing fabrics, finished with a top layer of gravel or asphalt. 

Known for its durability, BUR has been a trusted option for decades.

Pros:

• Excellent waterproofing and UV protection, making it ideal for sunny climates.
• Affordable long-term maintenance costs compared to more modern alternatives.
• Strong durability for high-traffic areas such as industrial buildings or schools.

Cons:

• Heavyweight, which may require additional structural support, increasing upfront costs.
• Longer installation process compared to other systems, leading to potential disruptions for businesses.

Best Uses:
BUR is ideal for flat or low-slope commercial buildings, especially those that require durable, long-lasting roofs.

 This type of roof performs exceptionally well in locations with heavy rainfall, as the multiple layers offer excellent water resistance.

Among commercial roof types, BUR continues to stand out for its resilience and cost-effectiveness, making it a popular choice for industrial and institutional properties.

Single-Ply Membranes (TPO, PVC, and EPDM)

Single-ply membrane systems offer a flexible and lightweight option for commercial roofing. 

These membranes are made from synthetic materials and are typically installed in large sheets, providing a seamless waterproof layer that reduces the risk of leaks.

TPO Pros:

• Energy-efficient and reflective, helping to reduce cooling costs in hot climates.
• It is affordable and easy to install, making it a budget-friendly option for businesses.

PVC Pros:

• Resistant to chemical exposure, making it perfect for factories or restaurants that handle grease and oils.
• Strong durability against wind and fire.

EPDM Pros:

• Exceptional resistance to weather and temperature changes, ideal for regions with extreme seasonal shifts.
• Long lifespan, with some installations lasting over 30 years with proper maintenance.

Cons:

• Vulnerable to punctures without proper protection, requiring careful handling.
• Requires professional installation for maximum performance and warranty validity.

Best Uses:
Single-ply systems are widely used for warehouses, retail centers, and healthcare facilities. 

Their versatility and energy efficiency make them one of the top types of commercial roofing for modern buildings looking to lower utility bills and extend roof lifespan.

Metal Roofing

Metal roofing is known for its durability, sleek appearance, and energy efficiency.

 Made from materials like steel, aluminum, or copper, metal roofs are built to last for decades, often outlasting other roofing materials.

Pros:

• Long lifespan of 40+ years with proper maintenance, reducing long-term replacement costs.
• Excellent resistance to fire, wind, and extreme weather, making it ideal for storm-prone areas.
• Recyclable and environmentally friendly, aligning with green building initiatives.

Cons:

• Higher initial investment compared to other systems, though the ROI is significant over time.
• It can be noisy during heavy rain or hailstorms without additional insulation.

Best Uses:
Metal roofing is best suited for industrial facilities, agricultural buildings, and commercial properties looking for a long-term, sustainable solution.

For businesses considering what are the best types of commercial roofing materials, metal stands out as a superior choice for its longevity, low maintenance, and energy savings.

Modified Bitumen Roofing

Modified bitumen is an asphalt-based roofing material reinforced with fiberglass or polyester for added strength. 

It’s a practical and cost-effective option for many commercial properties seeking reliability without a high price tag.

Pros:

• Easy to install and repair, keeping maintenance costs low and reducing downtime.
• Highly resistant to foot traffic, making it ideal for roofs that house HVAC systems or solar panels.
• Great flexibility, allowing it to expand and contract with temperature changes.

Cons:

• Prone to cracking in extreme temperatures without regular inspections.
• Limited aesthetic options compared to modern roofing systems.

Best Uses:
Modified bitumen works well for buildings that require frequent rooftop access, such as multi-family housing complexes, retail stores, and healthcare facilities.

 Its durability and ease of maintenance make it a go-to solution for roof types that prioritize functionality and affordability.

Green Roofing Systems

Green roofs, also known as vegetative roofing systems, are an increasingly popular choice for eco-conscious businesses. 

These systems involve adding layers of vegetation to the roof, which provides insulation, improves air quality, and reduces urban heat.

Pros:

• Significant energy savings through natural insulation and improved indoor comfort.
• Helps manage stormwater runoff and reduces the strain on drainage systems.
• Visually appealing, enhancing property value and creating a natural urban space.

Cons:

• Higher upfront costs for installation and maintenance compared to traditional systems.
• Requires a strong structural foundation to support the added weight of soil and plants.

Best Uses:
Green roofs are ideal for urban buildings, government facilities, and eco-conscious businesses looking to improve their environmental footprint while adding aesthetic value.

Choosing the Right Commercial Roofing System

With so many options available, selecting the right roofing system comes down to your building’s specific needs, budget, and location. 

Here are some key considerations:

• Climate: For areas with heavy rain or intense sunlight, reflective materials or durable options like metal may be best.
• Energy Efficiency: Cool roofs or green roofing systems are excellent for reducing energy costs and improving sustainability.
• Budget: BUR and modified bitumen are cost-effective for long-term use, while metal and SPF offer higher upfront costs with excellent ROI.
• Purpose: Consider the building’s function and whether the roof will need to support equipment or foot traffic.

Consulting with a professional is the best way to assess what are the best types of roofing materials for your property and long-term goals.

Conclusion

Choosing the right roofing system is an investment in your building's performance, energy efficiency, and longevity.

 Whether you’re looking for BUR's affordability, metal's durability, or green roofs' sustainability, each system has unique benefits that can enhance your property.
