Roofing materials play a crucial role in the protection and longevity of commercial buildings. With the wide array of options available, it can be challenging for business owners to choose the right material that meets their specific needs. In this comprehensive guide, we will compare the pros and cons of different roofing materials to help you make an informed decision for your commercial building.

Metal Roofing

Metal roofing has gained popularity in recent years due to its durability and longevity. It is available in various metals such as aluminium, steel, or copper. Let’s take a closer look at the pros and cons of metal roofing:

Pros of Metal Roofing

  • Durability: Metal roofs are known for their ability to withstand harsh weather conditions, including strong winds, heavy rain, and snow. They have a long lifespan, often lasting up to 50 years, making them a cost-effective choice in the long run.
  • Energy Efficiency: Metal roofs reflect sunlight, reducing heat absorption and keeping the building cooler. This energy-efficient feature can lead to lower cooling costs.
  • Versatility: Metal roofing comes in a variety of styles and colours, allowing you to choose an aesthetic that suits your building’s design.

Cons of Metal Roofing

  • Cost: Metal roofing can be more expensive upfront compared to other materials. However, its durability and longevity make it a worthwhile investment.
  • Noise: During rain or hailstorms, metal roofs can be noisy. However, proper insulation and underlayment can help reduce the noise.
  • Visual Preference: Some individuals may not prefer the appearance of metal roofs, as they can deviate from traditional roofing aesthetics.

Asphalt Shingles

Asphalt shingles are the most widely used roofing material in North America. They offer affordability and versatility. Let’s explore the pros and cons of asphalt shingles:

Pros of Asphalt Shingles

  • Affordability: Asphalt shingles are cost-effective and readily available, making them a popular choice for commercial buildings on a budget.
  • Easy Installation: They are relatively easy to install, saving both time and labour costs.
  • Variety of Styles: Asphalt shingles come in a wide range of colours and styles, allowing you to customise the appearance of your building.
  • Moderate Weather Resistance: Asphalt shingles can withstand moderate weather conditions, making them suitable for most regions.

Cons of Asphalt Shingles

  • Shorter Lifespan: Compared to other roofing materials, asphalt shingles have a shorter lifespan, typically ranging from 20 to 30 years.
  • Susceptible to Damage: Strong winds and impact from falling branches can damage asphalt shingles.
  • Maintenance Required: Regular maintenance, such as inspections and repairs, is necessary to ensure the longevity of asphalt shingle roofs.

EPDM Roofing

EPDM (ethylene propylene diene terpolymer) roofing is a synthetic rubber material commonly used in commercial buildings. Let’s delve into the pros and cons of EPDM roofing:

Pros of EPDM Roofing

  • Durability: EPDM roofs are highly durable and can withstand extreme temperatures, UV rays, and hail damage.
  • Flexibility: EPDM roofing material remains flexible in various weather conditions, allowing for expansion and contraction without damage.
  • Long Lifespan: With proper maintenance, EPDM roofs can last up to 50 years, providing long-term value for commercial buildings.
  • Energy Efficiency: EPDM roofs have excellent insulation properties, reducing energy consumption and lowering heating and cooling costs.

Cons of EPDM Roofing

  • Puncture Vulnerability: Sharp objects can puncture EPDM roofing, leading to leaks. Regular inspections and prompt repairs are necessary to maintain its integrity.
  • Limited Color Selection: Compared to other roofing materials, EPDM has a limited colour selection, potentially restricting design options.

TPO Roofing

TPO (thermoplastic polyolefin) roofing has gained popularity in recent years due to its cost-effectiveness and durability. Let’s examine the pros and cons of TPO roofing:

Pros of TPO Roofing

  • Cost-Effective: TPO roofing is generally more affordable compared to other commercial roofing materials.
  • Durability: TPO roofs can withstand extreme weather conditions, including high winds, hail, and UV rays.
  • Energy Efficiency: TPO roofing reflects sunlight, reducing heat absorption and lowering cooling costs.
  • Ease of Installation: TPO roofing is lightweight and easy to install, reducing labor costs and installation time.

Cons of TPO Roofing

  • Potential for Shrinkage and Cracking: TPO roofing may shrink and crack over time, leading to potential leaks. Regular inspections and maintenance are necessary to address any issues promptly.
  • Limited Color Selection: Similar to EPDM roofing, TPO has a limited color selection, which may impact design choices.

PVC Roofing

PVC (polyvinyl chloride) roofing is another popular single-ply membrane option for commercial buildings. Let’s explore the pros and cons of PVC roofing:

Pros of PVC Roofing

  • Durability: PVC roofs are highly durable, resistant to chemicals, UV rays, and extreme temperatures.
  • Fire Resistance: PVC roofing is inherently fire-resistant, providing an added layer of safety for commercial buildings.
  • Energy Efficiency: PVC roofs reflect sunlight, reducing heat absorption and lowering cooling costs.
  • Long Lifespan: With proper maintenance, PVC roofs can last up to 20-30 years.

Cons of PVC Roofing

  • Higher Cost: PVC roofing tends to be more expensive compared to other roofing materials.
  • Limited Color Selection: Similar to TPO and EPDM roofing, PVC has a limited color selection, potentially restricting design options.
  • Professional Installation Required: PVC roofing installation requires experienced professionals due to its specific installation techniques and requirements.

Built-Up Roofing (BUR)

Built-up roofing (BUR), also known as “tar and gravel” roofing, is a traditional method commonly used in commercial buildings. Let’s discuss the pros and cons of BUR:

Pros of Built-Up Roofing

  • Durability: Built-up roofing provides multiple layers of protection, making it highly durable and resistant to UV rays, heat, and water.
  • Long Lifespan: With proper maintenance, BUR roofs can last for decades, providing a reliable roofing solution.
  • Fire Resistance: The multiple layers of BUR provide excellent fire resistance, enhancing the safety of commercial buildings.

Cons of Built-Up Roofing

  • Weight: BUR roofs are heavier than other roofing materials, requiring additional structural support and potentially increasing costs.
  • Maintenance Required: Built-up roofing requires regular maintenance to prevent leaks and damage from ponding water.
  • Installation Complexity: BUR installation is more complex than other roofing materials, requiring skilled professionals with experience in its specific installation techniques.

As you consider the different roofing materials for your commercial building, it’s important to evaluate your specific needs, budget, and local climate conditions. Consulting with a professional roofing contractor can help you make an informed decision based on your unique requirements. Remember, investing in high-quality roofing materials is essential for the long-term protection and value of your commercial property.

Choosing the right roofing material for your commercial building is a significant decision that requires careful consideration. Each roofing material has its own pros and cons, and it’s important to evaluate them based on your specific needs, budget, and climate conditions. Metal roofing offers durability and longevity, while asphalt shingles provide affordability and versatility. EPDM, TPO, and PVC roofing options offer durability, energy efficiency, and a range of benefits. Built-up roofing provides a traditional and durable solution. By understanding the advantages and disadvantages of each material, you can make an informed decision that ensures the long-term protection and value of your commercial building.

Remember, when selecting a roofing material, it’s essential to consult with a professional roofing contractor who can assess your specific needs and provide expert advice.
