Flat Roofs, Metal Roofs, and More: Exploring Roofing Options for Commercial Buildings

When it comes to commercial buildings, one of the most critical elements that often goes unnoticed is the roof. The type of roofing material you choose can have a significant impact on the longevity, energy efficiency, and overall aesthetic of your property.

This post will explore various commercial roofing options, focusing on flat roofs and metal roofs, two popular choices among business owners.

Flat Roofs

Flat roofs are a common choice for commercial buildings for several reasons. Here are some key advantages and considerations:


  • Cost-Effective: Flat roofs are often more cost-effective to install and maintain compared to pitched roofs.
  • Usable Space: They offer additional usable space for equipment, solar panels, or even rooftop gardens.
  • Energy Efficiency: Flat roofs can be designed with cool roofing materials and reflective coatings, improving energy efficiency.


  • Drainage: Proper drainage is essential as flat roofs are prone to water pooling. Inadequate drainage can lead to leaks and damage.
  • Maintenance: Regular inspections and maintenance are necessary to prevent water infiltration and other issues.
  • Durability: The choice of roofing material is crucial for the lifespan of a flat roof.

Common flat roofing materials include Built-Up Roofing (BUR), Modified Bitumen, and EPDM (Ethylene Propylene Diene Monomer) rubber.

Metal Roofs

Metal roofs have gained popularity in commercial construction due to their durability and modern aesthetics. Here are some pros and cons to consider:


  • Durability: Metal roofs can last 40-70 years, making them a long-term investment.
  • Energy Efficiency: They reflect the sun’s rays, reducing cooling costs, and some are made with recycled materials, making them environmentally friendly.
  • Low Maintenance: Metal roofs require minimal maintenance.

  • Cost: The initial installation cost of metal roofs is higher than some other options, but their durability often offsets this expense.
  • Noise: Metal roofs can be noisy during heavy rain or hail, although proper insulation can mitigate this.

Common metal roofing materials include steel, aluminum, and copper. Standing seam and corrugated metal roofs are popular design choices.

Built-Up Roofing (BUR)

Built-up roofing, often referred to as a tar and gravel roof, is a traditional flat roofing option that offers a few unique advantages:


  • Waterproof: BUR is highly resistant to water infiltration due to multiple layers of asphalt and reinforcing fabrics.
  • Fire Resistance: It has excellent fire resistance, which is crucial for commercial properties.
  • Longevity: When properly maintained, BUR roofs can last 20-30 years.


  • Weight: BUR can be heavy, and the roof structure needs to be able to support it.
  • Installation: Installation can be labor-intensive and may emit odors during the process.
