The 3 Main Types Of Commercial Roofing Explained

Commercial buildings require robust roofing systems that can withstand the elements while providing long-term protection and energy efficiency. Choosing the right type of roofing for a commercial property involves considering factors like durability, maintenance requirements, and cost-effectiveness. In this article, we’ll explore the three primary types of commercial roofing commonly used today: Built-Up Roofing (BUR), Single-Ply Membrane Roofing, and Metal Roofing. Each type offers distinct advantages suited to different commercial applications.

👉 3 Main Types of Commercial Roofing

Understanding the main types of commercial roofing is crucial for business owners looking to protect their investments. Here, we explore three popular options—built-up roofing, single-ply membrane roofing, and metal roofing—each offering distinct advantages and characteristics tailored to different needs.

1. Built-Up Roofing (BUR)

Built-Up Roofing, or BUR, has been a stalwart in the commercial roofing industry for over a century. This traditional roofing system is composed of multiple layers of bitumen surfaces reinforced with fabrics like fiberglass or organic mats. These layers are alternated with bitumen and finished with a top layer of gravel or a mineral cap sheet. Let’s delve into the details of BUR:

Materials:

• Bitumen: Typically asphalt or coal tar, which provides waterproofing and durability.
• Reinforcement: Fiberglass or organic felts add strength and stability to the roofing system.
• Surfacing Materials: Gravel or a mineral cap sheet protects the underlying layers from UV rays and physical damage.

Benefits of BUR:

• Excellent Waterproofing: The multiple layers and gravel surfacing provide superior protection against water penetration.
• Durability: BUR systems are known for their longevity, often lasting 15 to 30 years with proper maintenance.
• Fire Resistance: Especially coal tar-based BUR offers significant fire resistance, making it suitable for buildings with strict fire safety requirements.
• UV Resistance: The gravel or mineral cap sheet reflects UV rays, prolonging the life of the roof.

Applications:

• BUR is ideal for low-slope or flat roofs commonly found on commercial buildings.
• It is well-suited for buildings with heavy foot traffic and equipment installations, thanks to its robust construction.

2. Single-Ply Membrane Roofing

Single-Ply Membrane Roofing systems are relatively modern but have quickly gained popularity due to their ease of installation and versatility. These roofs consist of a single layer of synthetic or rubber membrane that is either mechanically fastened, adhered with adhesives, or ballasted over the insulation layer. Here’s what you need to know about single-ply membranes:

Materials:

• PVC (Polyvinyl Chloride): Known for its durability and resistance to chemicals.
• TPO (Thermoplastic Polyolefin): Offers excellent flexibility and heat-welded seams.
• EPDM (Ethylene Propylene Diene Monomer): Rubber-based membrane known for its longevity and ease of installation.

Benefits of Single-Ply Membrane Roofing:

• Lightweight: These roofs are lightweight compared to other systems, reducing the load on the building structure.
• Energy Efficiency: Reflective surfaces (especially TPO and PVC) can reduce cooling costs by reflecting solar heat.
• Low Maintenance: Single-ply membranes require minimal maintenance and are easy to repair if damaged.
• Versatility: Suitable for various roof designs and shapes, including irregular structures.

Applications:

• Single-ply membrane roofing is suitable for both new construction and roof replacement projects.
• It is ideal for buildings where quick installation and minimal disruption are priorities.

3. Metal Roofing

Metal roofing has evolved from its industrial origins to become a preferred choice for many modern commercial roofing systems. These roofs are typically made from steel, aluminum, or copper sheets, offering durability, aesthetic appeal, and energy efficiency. Here’s a closer look at metal roofing systems:

Materials:

• Steel: Known for its strength and durability, suitable for various climate conditions.
• Aluminum: Lightweight and resistant to corrosion, making it ideal for coastal areas.
• Copper: Offers a distinctive aesthetic appeal and exceptional durability, often used in historic or high-end commercial buildings.
• Zinc: Combines durability with a lower environmental impact due to its recyclability.

Benefits of Metal Roofing:

• Longevity: Metal roofs can last 50 years or more with proper maintenance, making them a cost-effective choice over the long term.
• Strength and Resistance: Metal roofs are resistant to fire, mildew, insects, and rot.
• Energy Efficiency: Reflective coatings and insulation can significantly reduce cooling costs, especially in warmer climates.
• Aesthetic Options: Available in various colors, finishes, and profiles to complement different architectural styles.

Applications:

• Metal roofing is suitable for both sloped and flat roofs, offering versatility in design and application.
• It is favored in commercial buildings where durability, low maintenance, and aesthetic appeal are priorities.

🤔 Choosing the Right Roofing System

Selecting the appropriate roofing system for a commercial building involves considering several factors:

• Climate and Weather Conditions: Choose a roof that can withstand local weather patterns, including wind, rain, snow, and UV exposure.
• Building Structure: Consider the roof’s slope, size, and existing infrastructure when selecting a roofing system.
• Maintenance Requirements: Assess ongoing maintenance needs and costs to ensure the roof remains in optimal condition.
• Budget and Long-Term Costs: Balance initial installation costs with long-term savings on energy efficiency and maintenance.
