What is the Most Common Roofing Material?

What is the Most Common Roofing Material? A Guide from Motor City Roofers in Detroit, Michigan
When it comes to choosing the best roofing material for commercial or residential buildings, there’s no one-size-fits-all answer. The “best” material depends on a range of factors, including climate, building structure, cost, and maintenance needs. However, some roofing materials are consistently more popular than others, particularly for commercial properties where durability, cost-efficiency, and ease of installation play a key role in decision-making.

At Motor City Roofers, we understand the unique needs of commercial properties in Detroit, Michigan. Our region’s climate, with its harsh winters and humid summers, calls for roofing materials that can withstand significant temperature swings, heavy snow loads, and potentially damaging UV rays. Below, we’ll explore some of the most common roofing materials used today, their unique properties, and why certain materials are better suited for Detroit's climate.

1. Asphalt Shingles
Overview: Asphalt shingles are by far the most common roofing material for residential buildings across the United States and have also been used in some smaller commercial buildings. They are popular because they are affordable, versatile, and relatively easy to install. Asphalt shingles are typically made of fiberglass or organic materials, coated with asphalt and topped with mineral granules for added protection.
Pros:

• Affordability: Asphalt shingles are one of the most cost-effective roofing materials.
• Variety: They come in a wide range of colors and styles, making it easy to match architectural preferences.
• Ease of Installation and Repair: Installation is straightforward, and damaged shingles can be individually replaced.

Cons:

• Durability: Asphalt shingles are generally less durable than other commercial roofing materials and may not withstand Detroit’s intense winters and summers as well as other materials.
• Shorter Lifespan: Asphalt shingles have a lifespan of 20-30 years, which is shorter than many alternatives.

Best for: Residential buildings and small commercial buildings in areas with moderate climates.

2. TPO (Thermoplastic Polyolefin)
Overview: TPO is a single-ply roofing membrane made of a blend of polypropylene and ethylene-propylene rubber. It has gained popularity in commercial roofing due to its energy efficiency and cost-effectiveness. TPO is particularly appealing in areas with warmer climates, but it has also performed well in colder climates like Detroit’s.
Pros:

• Energy Efficiency: TPO membranes reflect UV rays, reducing cooling costs during hot summers.
• Durability: Resistant to punctures, tears, and most chemicals.
• Cost-Effective: TPO is typically more affordable than other commercial roofing options like PVC and EPDM.

Cons:

• Quality Variations: Since TPO is a relatively new material, the quality can vary significantly depending on the manufacturer.
• Seam Integrity: Over time, TPO seams may become vulnerable if not properly installed and maintained.

Best for: Flat or low-slope commercial roofs, particularly for properties looking to reduce energy costs.

3. EPDM (Ethylene Propylene Diene Monomer)
Overview: EPDM, commonly referred to as “rubber roofing,” is a synthetic rubber membrane that has been widely used in commercial roofing for decades. Its reputation for durability and flexibility in extreme temperatures has made it a top choice for flat roofs, particularly in areas with variable weather like Michigan.
Pros:

• Durability: EPDM can last up to 30 years or more with proper maintenance.
• Flexibility: This material can expand and contract with temperature changes, making it ideal for Detroit’s variable climate.
• Low Maintenance: EPDM is relatively low maintenance and can withstand UV exposure and ozone.

Cons:

• Aesthetics: Black EPDM absorbs heat, which may increase cooling costs in the summer unless a reflective coating is applied.
• Vulnerability to Punctures: Though durable, EPDM can be punctured by sharp objects or debris, which can lead to leaks.

Best for: Flat and low-slope commercial roofs in variable climates, especially those looking for a long-lasting material.

4. Metal Roofing
Overview: Metal roofing is popular for both commercial and industrial properties due to its exceptional durability and longevity. Typically made from steel, aluminum, or copper, metal roofing systems can be used on low-slope and steep-slope roofs. Metal roofing is ideal for Detroit’s climate, as it can handle heavy snowfall, resist corrosion, and perform well under varying temperatures.
Pros:

• Longevity: Metal roofs can last 40-70 years, making them one of the longest-lasting roofing materials available.
• Weather Resistance: Metal roofing can withstand extreme weather conditions, including heavy snow, strong winds, and hail.
• Sustainability: Metal is highly recyclable, making it an eco-friendly option.

Cons:

• Cost: Metal roofs have a higher upfront cost than many other materials.
• Noise: Without proper insulation, metal roofs can be noisier during rain or hailstorms.
• Expansion and Contraction: Metal expands and contracts with temperature changes, which may lead to issues with fasteners over time.

Best for: Large commercial buildings in regions with harsh weather, especially those that prioritize longevity and minimal maintenance.

5. Modified Bitumen
Overview: Modified bitumen roofing is a multi-ply roofing system often used for flat or low-slope roofs. It is made from asphalt with added modifiers to enhance flexibility and durability. Modified bitumen can be applied through various techniques, including torch-down, cold adhesive, or self-adhered methods.
Pros:

• Durability: Modified bitumen is strong, puncture-resistant, and can withstand heavy foot traffic.
• Weather Resistance: It performs well under various weather conditions, including Detroit’s snowy winters.
• UV Resistance: Some modified bitumen systems are designed with UV resistance, helping to reduce heat absorption.

Cons:

• Installation Complexity: The installation process can be labor-intensive and requires professional expertise.
• Limited Lifespan: Modified bitumen roofing generally lasts around 20 years, which is shorter than some other commercial options.

Best for: Flat commercial roofs that need additional durability and resistance to weather and foot traffic.

6. PVC (Polyvinyl Chloride)
Overview: PVC roofing is another single-ply membrane option, similar to TPO, but with enhanced chemical and puncture resistance. PVC is especially popular in commercial applications where chemical exposure is common, such as restaurants and factories.
Pros:

• Chemical Resistance: PVC is resistant to grease, chemicals, and fire, making it ideal for certain commercial applications.
• Durability: Known for its durability and ability to withstand various environmental factors.
• Energy Efficiency: Reflects UV rays, helping to reduce cooling costs in the summer.

Cons:

• Cost: PVC roofing is generally more expensive than TPO and EPDM.
• Environmental Concerns: The production and disposal of PVC can have a greater environmental impact than some other materials.

Best for: Commercial roofs in sectors with specific requirements, such as food production and chemical processing, as well as buildings seeking energy-efficient solutions.
