What is the Best Commercial Roofing Material?

Choosing the best material for your commercial roofing system requires an evaluation of what makes sense for your local climate and building needs, since this critical decision will impact the protection of your building and energy efficiency for years to come. Whether you’re managing a new construction, planning a roof replacement, or upgrading an existing commercial property in Michigan, the right roofing material safeguards your investment while helping control costs.

But with so many commercial roofing options available, how do you determine the best commercial roofing material for your unique Michigan needs? Let’s explore the best choices for commercial roofing systems suited to Michigan’s weather and building requirements.

What Are the Various Types of Commercial Roofing Materials

Understanding the range of commercial roofing products and how each performs is key to a successful commercial roofing project.

Metal Roofing Systems

Metal roofing, including panels made from galvanized steel, steel sheet, or aluminum, delivers top-tier durability and a life expectancy of 30–45+ years. Metal roofs come in various types, which are typically installed using specific fastening methods to maximize weather resistance and longevity. Standing seam roofing is particularly popular for its hidden fasteners and weather tightness, making it ideal for both commercial roofing projects and certain high-end residential roofs.

Pros

• Exceptional in high-wind, hail-prone environments
• Fire resistant, recyclable, and strong against punctures
• Low maintenance and compatible with roof coatings for added energy savings

Cons

• Higher up-front costs vs. many roofing membranes
• Thermal movement may impact fastener integrity if not installed by a skilled roofing contractor

Built-Up Roofing (BUR)

BUR roofing (or built-up roof, a traditional layered system) is among the oldest systems, employing multiple layers of roofing felt, hot mopped asphalt, and aggregate for protection.

A typical bur roof installation involves alternating layers of felt, bitumen, and asphalt, finished with gravel or rock. The underlayment membrane strengthens the BUR roof, increasing its durability and lifespan. Regular maintenance keeps the system performing at its best.

Pros

• Superior waterproofing and puncture resistance
• Proven durability under high foot traffic
• Excellent for large commercial flat roofing projects

Cons

• Installation involves hot asphalt, which can be disruptive
• Heavier weight may require deck reinforcement

Modified Bitumen Roofing

Modified bitumen systems are an evolution of BUR, incorporating rubber or plastic modifiers into asphalt sheets for extra elasticity and resilience.

Pros

• Flexible, well-suited for buildings with movement or vibration
• Easy to maintain and repair with additional roof layers or coatings

Cons

• Lower reflectivity unless surfaced with a reflective cap sheet
• Requires experienced installers for proper installation

Single Ply Roofing Systems

Single-ply roofing systems include two main types: thermoset membranes (EPDM roofing) and thermoplastic (PVC roofing, TPO). The roof membrane is the primary waterproofing and protective layer in single-ply roofing systems, such as EPDM and PVC.

EPDM Roofing

• EPDM roof membranes are known for flexibility, weather resistance, and longevity of 20–30 years. Resists UV exposure, ozone, and extreme temperatures, making them a top choice for large commercial roofs.
• Easy maintenance and low cost, especially for retrofits.

PVC Roofing and TPO

• PVC roofing and TPO are lightweight, highly reflective, and suitable for food service or chemical-exposed settings.
• Heat-welded seams create a waterproof seal and resist high winds.

Green Roofs & Vegetative Roofing Systems

Green roofs (or vegetative roofing systems) involve a living ecosystem of plants, soil, and waterproof membranes. These systems are typically installed in layers, including a waterproof membrane, root barrier, and drainage layer.

Pros

• Reduce surface moisture through natural absorption
• Lower stormwater runoff and enhance energy performance
• Contribute to green building certifications (e.g., LEED)

Cons

• High installation cost and significant maintenance requirements
• Requires structural engineering and enhanced roof deck load capacity

What Are the Factors to Consider When Choosing a Commercial Roofing System?

Roof Slope and Structure

The types of commercial roofing vary depending on the roof pitch. For instance, many warehouses, shopping plazas, and multi-family developments in Michigan have low, flat roofing systems that necessitate a particular material and application to preserve soundness and water drainage. Steep slope roofs are typically found on institutional buildings or historic structures throughout the state.

Building Usage and Foot Traffic

The purpose of your commercial building in Michigan, whether it’s an office, retail space, manufacturing facility, or apartment complex, determines the most suitable roof system. Roofs that support HVAC equipment or experience frequent foot traffic need to be constructed with durable, resilient materials to withstand regular use.

Local Climate & Environmental Conditions

Michigan’s diverse climate, with cold winters, heavy snow, and occasional high winds, demands commercial roofing systems that can endure these conditions. Metal roofing materials such as galvanized steel are often preferred for their resistance to rust and ability to withstand Michigan’s weather extremes, including snow loads and ice buildup.

Building Codes & Regulations

It’s essential to ensure that your chosen roofing materials, insulation, and drainage systems comply with Michigan’s building codes. This includes meeting requirements for fire resistance, wind uplift standards, and stormwater management to protect your property and meet local regulations.

Energy Efficiency and Sustainability

Energy efficiency is a key consideration for commercial buildings, focusing on roof reflectivity, insulation quality, and opportunities for solar panel integration. Green roofs and vegetative roofing systems are gaining popularity in Michigan for their ability to reduce energy costs and manage stormwater runoff effectively.

Maintenance Requirements and Lifespan

Some roofing systems are designed for low maintenance. In contrast, others, such as built-up roofing or modified bitumen roofing, require regular roof coatings or protective surfacing to maintain performance and extend lifespan in the state’s climate.

Commercial Roof System Comparison Table

Material	Durability	Energy Efficiency	Maintenance Level	Best Uses
Metal Roofing Systems	30–45 yrs	High (w/coatings)	Low	Steep/low slope, all areas
BUR Roofing	20–30 yrs	Moderate	Moderate	Flat, high-traffic roofs
Modified Bitumen	15–25 yrs	Moderate/Fair	Moderate	Flat, complex patches
EPDM Roof	20–30 yrs	Moderate	Low	Large commercial roofs
PVC/TPO Roofing	20–30 yrs	High	Moderate	Food, chemical exposure
Green Roofs	20–40 yrs	Excellent	High	Eco-focused, urban
Roof Coatings	N/A	Boosts existing	Low-Moderate	Extending roof lifespan

Why Hire a Professional Roofing Contractor?

Hiring a professional roofing contractor plays a key role in bringing your commercial roofing project to a successful outcome. Here are several reasons why hiring an expert makes all the difference:

• Safety Compliance. Roofing work involves significant safety risks, especially on large commercial buildings. Licensed and insured contractors will follow local safety standards and use materials and equipment that protect workers (and your property).
• Quality Materials and Tools. A commercial roofing contractor has access to quality materials and tools that the average consumer does not have access to. This access helps guarantee a durable, long-lasting roofing solution.
• Warranty Protection. Many roofing manufacturers require professional installation for warranty coverage. Hiring a certified contractor means your roof system is more likely to be covered against defects and premature failure.
• Efficient Project Management. Experienced contractors coordinate all aspects of the roofing project, from scheduling and permits to inspections and cleanup. This management reduces delays and keeps the job on schedule and within budget.
• Cost-Effectiveness. While hiring a professional may seem like a higher upfront investment, it often saves money over time by avoiding premature roof failures and expensive repairs. Their expertise also helps optimize material use and labor efficiency.
