Types of Commercial Metal Roofing

Are you considering installing a commercial metal roof but are still determining which option is the most suitable for your building? Consider evaluating the pros and cons before making a significant investment. Priority Roofing recognizes that investing in a commercial metal roof is a substantial decision, and it’s crucial to make choices that ensure you get the maximum return on your investment. With this comprehensive guide, we’ll walk you through everything you need to know about commercial metal roofing, helping you make an informed decision.

Types of Commercial Metal Roofing Systems

There are several types of commercial metal roofing systems, each offering its own set of advantages and disadvantages. Here’s a breakdown of the most popular options commonly installed on commercial buildings, along with their impact on the building’s aesthetics:

  • Standing Seam: This roofing system features raised seams that run vertically across the roof, providing a sleek and modern appearance. The panels, typically crafted from steel or aluminum, are secured to the roof deck using concealed clips and fasteners. This hidden attachment method adds to the clean aesthetic and provides a durable and weather tight seal.
  • R-Panel or Multi-Rib Panels: Known for their ribbed design, R-panel or multi-rib roofing is made of steel and is one of the more budget-friendly choices. It’s easy to install and often favored for commercial and industrial buildings. However, unlike standing seam roofs, this option has exposed fasteners (also referred to as a ‘screw-down’ roof), which can be a consideration for long term maintenance due to the potential for these fasteners to loosen over time and require re-tightening.
  • Trapezoid Panel: As a variation of standing seam roofing, the trapezoid metal roofing system features panels that are wider at the base and narrower at the top, forming a trapezoidal shape. This unique design enhances water drainage and accommodates thermal expansion and contraction, a process where the metal panels expand and contract with temperature changes, making it an ideal choice for low-slope roof structures commonly found in commercial applications.
  • Corrugated Metal: Recognizable by its wavy, ribbed pattern, corrugated metal roofing is made from either steel or aluminum. It’s lightweight, highly durable, and one of the most cost effective options, making it particularly popular for industrial buildings. Its simplicity and affordability make it an option for many commercial settings.
  • Metal Shingles: Designed to replicate the appearance of traditional shingles, metal shingles offer the classic look of conventional roofing but with the added benefits of metal’s durability. These shingles can be made from materials like aluminum, steel, or zinc. While they tend to be more expensive than other metal roofing types, they provide an appealing aesthetic combined with enhanced longevity.
  • Stone Coated Steel: This roofing option consists of steel panels coated with ceramic-coated stone granules, giving them the look of traditional shingles while maintaining the strength and durability of metal. This combination offers the classic aesthetic of conventional shingle roofing and a more long-lasting and resilient solution.

How Long Do Metal Roofs Last?

The longevity of a commercial metal roof can vary depending on the type of metal used, the quality of installation, and how well it’s maintained over time. On average, you can expect a commercial metal roof to last 20 to 50 years, but this can differ depending on the specific roofing system. Metal roofs must be particularly resilient in areas like New Orleans, which has a humid, subtropical climate with heavy rainfall and occasional hurricanes. Here’s an overview:

  • Standing Seam Metal Roofs: These roofs, typically made from high quality materials like aluminum, steel, or galvalume, are known for their durability. With proper upkeep and regular maintenance, they can exceed a lifespan of 50 years.
  • R-Panel and Corrugated Metal Roofing Systems: These options offer a more budget-friendly solution but tend to have a shorter lifespan than other metal roofing types. With proper care, they can generally last 20 to 25 years.
  • Stone Coated Steel and Metal Shingles: Combining durability with a more traditional appearance, stone coated steel and metal shingles can endure for about 50 years, making them a long lasting choice for many commercial buildings.

Advantages of Commercial Metal Roofing

Metal roofing systems have several advantages that make them a popular choice for industrial and commercial roofing:

  • Durability: Metal roofs are known for their durability and can last several decades with proper maintenance. They are resistant to fire, wind, and impact, making them an excellent option for areas prone to severe weather.
  • Energy-efficient: They can reflect a significant amount of the sun’s heat, reducing summer cooling costs and making them a cost-effective and environmentally conscious choice for commercial and industrial buildings.
  • Lightweight: Metal roofs are lightweight compared to other roofing materials, making them easy to install and less likely to stress the building’s structure.
  • Low maintenance: Metal roofs require very little, making them a stress free and cost effective option in the long run. They are resistant to rot, mildew, and pests and can be easily cleaned with a hose, providing peace of mind for building owners and property managers.
  • Environmentally Friendly: Many metal roofs are made from recycled materials and are also recyclable at the end of their lifespan. This long lifespan reduces the need for frequent replacements.
  • Commercial metal roofs come in a wide array of colors, styles, and finishes, offering a versatile palette to enhance a building’s aesthetic and add to its curb appeal. This variety of design options can inspire creativity and help you achieve the look you desire for your commercial property.

Disadvantages of Commercial Metal Roofing

While commercial metal roofing systems have many advantages, there are also some disadvantages to consider:

  • Cost: Metal roofs can be more expensive than other types of roofing, especially if you choose high end materials or a more complex installation.
  • Noise: Metal roofs can be noisy during heavy rain or hail, which may be a concern for some buildings. However, adding insulation can help reduce this noise.
  • Dents and Scratches: Metal roofs can be dented or scratched, which can affect their appearance and longevity. Opting for thicker, higher gauge metal can minimize this issue.
  • Expansion and Contraction: Metal roofs naturally expand and contract with temperature changes, which can cause them to warp, bend, or even crack over time. Addressing this issue during installation and selecting high-quality materials can help reduce the impact.
  • Installation Complexity: Installing a metal roof is typically more complex and time consuming than other roofing types. It demands specialized equipment and skilled professionals experienced with metal roofing systems. This requirement can contribute to higher labor costs but is essential for a quality installation that will last.

Maintenance Tips for Commercial Metal Roofs

Proper maintenance plays a crucial role in extending the lifespan of a commercial metal roof:

  • Regular Inspections: Inspect your roof regularly for signs of wear, rust, or damage and address any issues promptly.
  • Clean Debris and Gutters: Remove debris, leaves, and any vegetation that may accumulate on the roof and clean gutters to ensure proper water drainage.
  • Address Loose Fasteners: Check for and tighten any loose fasteners, as they can cause leaks over time.
  • Apply Protective Coatings: Consider applying protective coatings to extend your roof’s life, enhance its weather resistance, and prevent corrosion.
