Choosing the Right Roofing Material

Choosing the Right Roofing Material: A Comprehensive Guide by Motor City Roofers
Selecting the right roofing material for your commercial building is one of the most critical decisions you’ll make as a property owner or manager. Not only does the roof protect your structure and assets, but it also contributes to energy efficiency, aesthetic appeal, and overall building performance. At Motor City Roofers, located in Detroit, Michigan, we understand the complexities of commercial roofing, and we aim to guide you through the decision-making process to ensure you choose the best material for your unique needs.

In this article, we’ll explore the different types of commercial roofing materials available, highlighting their advantages and disadvantages, and provide some tips on how to make the best choice for your building.

1. Built-Up Roofing (BUR)Advantages:Built-up roofing (BUR), commonly referred to as “tar and gravel” roofing, is one of the oldest roofing systems in the industry. This roofing material consists of multiple layers of bitumen and reinforcing fabrics, topped with a layer of gravel or other aggregate.

• Durability: One of the primary benefits of BUR is its durability. With multiple layers, this roofing system offers excellent protection against harsh weather conditions like Detroit's snowy winters and summer heat.
• Waterproof: The layers create a waterproof membrane, which protects your building from leaks and water infiltration.
• Low Maintenance: BUR requires minimal maintenance once installed, making it a long-lasting and low-maintenance solution.

​
Disadvantages:

• Installation Time: BUR can take longer to install than other roofing systems, leading to higher labor costs.
• Weight: The multiple layers can make BUR quite heavy, which may require additional structural support in some buildings.

2. Modified Bitumen RoofingAdvantages:Modified bitumen roofing is a type of asphalt roofing that has been enhanced with polymer modifiers to improve its flexibility and durability. This roofing material is commonly installed in two layers and is often used for flat or low-slope commercial roofs.

• Flexibility: Modified bitumen is more flexible than traditional BUR systems, making it a good choice for buildings that experience movement or expansion.
• UV Resistance: This roofing material offers excellent resistance to ultraviolet (UV) rays, which helps to extend the lifespan of your roof in areas with high sun exposure.
• Ease of Installation: Modified bitumen can be installed using a variety of methods, including heat welding and self-adhering sheets, making it relatively easy and quick to install.

Disadvantages:

• Potential for Damage: While modified bitumen is durable, it is not immune to punctures, tears, or damage from heavy foot traffic.
• Cost: Modified bitumen roofing systems tend to be more expensive than some other options.

3. EPDM (Ethylene Propylene Diene Monomer) RoofingAdvantages:EPDM is a type of synthetic rubber roofing membrane that is known for its flexibility, durability, and cost-effectiveness. It is particularly well-suited for flat or low-slope commercial roofs.

• Cost-Effective: EPDM is one of the most affordable roofing materials available for commercial buildings.
• Weather Resistance: EPDM is highly resistant to extreme weather conditions, including UV rays, hail, and temperature fluctuations.
• Longevity: With proper maintenance, an EPDM roof can last up to 30 years or more.

Disadvantages:

• Aesthetics: EPDM is typically available in black, which can absorb heat and raise cooling costs. However, lighter-colored options are available at a higher cost.
• Vulnerability to Punctures: While durable, EPDM can be susceptible to punctures and tears, particularly in high-traffic areas or where heavy equipment is used.

4. TPO (Thermoplastic Polyolefin) RoofingAdvantages:TPO is a single-ply roofing membrane that has gained popularity in recent years due to its energy-efficient properties and affordability. TPO roofs are typically white, which helps reflect sunlight and reduce heat absorption.

• Energy Efficiency: TPO’s reflective surface helps reduce cooling costs by reflecting UV rays, making it an ideal choice for warmer climates or buildings that need to improve energy efficiency.
• Durability: TPO is resistant to dirt, mold, and punctures, making it a low-maintenance option.
• Affordability: TPO is relatively inexpensive compared to other single-ply membranes like PVC.

Disadvantages:

• Newer Technology: TPO is still a relatively new roofing material, and long-term performance data is limited compared to EPDM and BUR.
• Installation Quality: The quality of the installation can significantly impact the performance of TPO roofs. It’s important to choose a qualified contractor like Motor City Roofers to ensure proper installation.

5. PVC (Polyvinyl Chloride) RoofingAdvantages:PVC roofing is another single-ply membrane option that is highly durable and resistant to chemicals, fire, and UV rays. It is often used on commercial buildings with flat roofs.

• Durability: PVC is known for its strength and durability, particularly in areas with chemical exposure or harsh environmental conditions.
• Energy Efficiency: Like TPO, PVC roofs are typically white and reflective, helping to reduce energy consumption by lowering cooling costs.
• Fire-Resistant: PVC is highly fire-resistant, making it a good choice for buildings that require enhanced fire safety.

Disadvantages:

• Cost: PVC is one of the more expensive roofing materials, which may make it less appealing for budget-conscious property owners.
• Brittleness: Over time, PVC can become brittle, particularly in cold climates, which may lead to cracking or other damage.

6. Metal RoofingAdvantages:Metal roofing systems have been a staple in commercial roofing for decades, known for their longevity, durability, and energy efficiency. Common metals used include steel, aluminum, and copper.

• Longevity: Metal roofs can last 40 to 70 years, making them one of the longest-lasting roofing options.
• Durability: Metal is highly resistant to fire, wind, and extreme weather conditions, making it an excellent choice for buildings in harsh environments.
• Energy Efficiency: Metal roofs reflect heat, which can help reduce cooling costs in the summer.

Disadvantages:

• Cost: Metal roofing systems are more expensive upfront compared to other roofing materials.
• Noise: Metal roofs can be noisy during heavy rain or hail unless additional insulation is installed.

7. Green RoofingAdvantages:Green roofs, also known as living roofs, involve covering the roof with vegetation and soil, creating an environmentally friendly roofing option.

• Energy Efficiency: Green roofs provide excellent insulation, helping to reduce heating and cooling costs throughout the year.
• Environmental Benefits: Green roofs help reduce stormwater runoff, improve air quality, and provide habitats for wildlife.
• Aesthetic Appeal: Green roofs add a unique and attractive feature to your building.

Disadvantages:

• Cost: Green roofs are expensive to install and require ongoing maintenance to keep the vegetation healthy.
• Structural Support: Your building may require additional structural support to handle the weight of the soil and vegetation.
