Most Common Types of Commercial Roofing Materials Used

When it comes to commercial roofing, the materials you choose play a critical role in the longevity, durability, and performance of your roof. A commercial roof is a significant investment, and selecting the right material ensures your building is protected against the elements while optimizing energy efficiency and minimizing maintenance costs. At Motor City Roofers in Detroit, Michigan, we understand that every business has unique needs, and we aim to provide expert guidance on selecting the best roofing materials for your project. In this article, we will explore the most common types of commercial roofing materials, their benefits, and factors to consider when making your choice.

1. Thermoplastic Polyolefin (TPO) RoofingOverview:
TPO is a single-ply membrane made from a blend of polypropylene and ethylene-propylene rubber. It has become one of the most popular commercial roofing materials due to its energy efficiency and durability.
Advantages:

• Energy Efficiency: TPO’s reflective surface reduces heat absorption, lowering cooling costs.
• Durability: It resists UV rays, punctures, chemicals, and bacteria growth.
• Flexibility: TPO can accommodate building movement, making it ideal for Detroit’s fluctuating weather conditions.
• Cost-Effective: TPO is generally more affordable than other single-ply options like PVC.

Considerations:

• TPO installation requires experienced contractors to ensure proper sealing.
• While it is durable, the quality of TPO membranes can vary depending on the manufacturer.

2. Ethylene Propylene Diene Monomer (EPDM) RoofingOverview:
EPDM, commonly known as a rubber roof, is a single-ply membrane made from synthetic rubber. It has been a staple in the commercial roofing industry for decades.
Advantages:

• Weather Resistance: EPDM is highly resistant to extreme temperatures, UV rays, and hail damage.
• Longevity: With proper maintenance, an EPDM roof can last up to 30 years or more.
• Cost-Effective: EPDM is one of the most affordable commercial roofing options.
• Ease of Repair: Its rubber material is easy to patch if damage occurs.

Considerations:

• EPDM roofs are black, which can absorb heat and increase cooling costs in warm climates.
• While durable, EPDM is more prone to punctures compared to TPO or PVC.

3. Polyvinyl Chloride (PVC) RoofingOverview:
PVC is another single-ply membrane that is known for its exceptional durability and chemical resistance.
Advantages:

• Chemical Resistance: Ideal for buildings exposed to grease, oil, or harsh chemicals, such as restaurants or industrial facilities.
• Energy Efficiency: PVC roofs reflect sunlight, reducing energy consumption.
• Fire Resistance: PVC is self-extinguishing, offering additional safety benefits.
• Durability: It is highly resistant to punctures, tears, and weathering.

Considerations:

• PVC is typically more expensive than TPO and EPDM.
• The material can become brittle over time, especially in extremely cold climates.

4. Metal RoofingOverview:
Metal roofing is a versatile option for commercial buildings, often made from aluminum, steel, or zinc. It is favored for its longevity and sustainability.
Advantages:

• Longevity: Metal roofs can last 40-70 years with proper maintenance.
• Durability: Resistant to fire, wind, and impact damage.
• Sustainability: Many metal roofs are made from recycled materials and are 100% recyclable at the end of their lifespan.
• Energy Efficiency: Metal roofs can be coated with reflective finishes to reduce heat absorption.

Considerations:

• Metal roofing has a higher upfront cost than other materials.
• It can be noisy during heavy rain or hail unless soundproofing measures are taken.
• Improper installation can lead to issues with water pooling or leaks.

5. Built-Up Roofing (BUR)Overview:
BUR is a traditional roofing system consisting of multiple layers of asphalt, tar, or adhesive, alternated with layers of felt or fiberglass. It is then topped with a layer of gravel or a reflective coating.
Advantages:

• Durability: The multiple layers provide excellent protection against water and weather.
• UV Resistance: The top layer of gravel or reflective coating protects against UV rays.
• Proven Track Record: BUR systems have been used successfully for over a century.

Considerations:

• BUR installation can be time-consuming and labor-intensive.
• It is heavier than single-ply systems, requiring proper structural support.
• Regular maintenance is necessary to prevent cracks or damage.

6. Modified Bitumen RoofingOverview:
Modified bitumen is an evolution of BUR systems, combining asphalt with polymer materials to enhance flexibility and durability. It is often applied in rolls and can be torch-applied or adhered with cold adhesive.
Advantages:

• Flexibility: Modified bitumen performs well in various temperatures, making it suitable for Detroit’s climate.
• Durability: It is resistant to tears and punctures, especially when reinforced with fiberglass or polyester.
• Ease of Installation: Available in peel-and-stick options for quick installation.

Considerations:

• Modified bitumen is not as reflective as TPO or PVC, leading to higher cooling costs.
• The torch-applied method can pose safety risks if not performed by trained professionals.

7. Spray Polyurethane Foam (SPF) RoofingOverview:
SPF is a unique roofing system that involves spraying a liquid mixture onto the roof, which then expands into a solid foam layer.
Advantages:

• Seamless Installation: SPF creates a watertight seal that eliminates seams and gaps.
• Energy Efficiency: It provides excellent insulation, reducing heating and cooling costs.
• Lightweight: SPF is ideal for buildings with weight limitations.
• Longevity: With proper maintenance, SPF can last up to 30 years.

Considerations:

• SPF installation requires specific weather conditions, such as dry and mild temperatures.
• Regular maintenance is necessary to maintain the protective topcoat.
• Installation requires skilled professionals for proper application.

Factors to Consider When Choosing a Commercial Roofing MaterialWhen selecting the right roofing material for your commercial building, it’s essential to consider the following factors:

• Climate: Detroit experiences a wide range of weather conditions, including heavy snow, rain, and heat. Choose a material that can withstand these challenges.
• Building Usage: Consider how your building is used. For example, a restaurant may require a roof with excellent grease and chemical resistance, while an office building may prioritize energy efficiency.
• Budget: Evaluate both upfront costs and long-term expenses, such as maintenance and energy savings.
• Lifespan: Consider how long you plan to occupy the building and choose a material that aligns with your long-term plans.
• Environmental Impact: Opt for sustainable materials if reducing your environmental footprint is a priority.
