What Makes Commercial Roofing Unique?
Commercial roofing differs significantly from residential roofing in several ways:
- Size and Structure: Commercial roofs typically cover larger areas and are designed to support heavy equipment like HVAC systems.
- Materials Used: The materials used for commercial roofs must withstand different environmental stresses and provide durability over extended periods.
- Installation Complexity: The installation process often involves specialized techniques and equipment due to the roof’s size and purpose.
These unique elements make choosing the right commercial roofing system a challenging but essential task for building owners.
5 Different Types of Commercial Roofing
Commercial roofing comes in various types, each with its own benefits and drawbacks. Here are the most common options:
1. TPO Roofing
Thermoplastic Olefin (TPO) roofing is a popular choice due to its energy efficiency and durability. It’s resistant to chemicals, punctures, and UV radiation, making it ideal for various climates.
✅ Pros:
- Highly reflective surface reduces energy costs
- Environmentally friendly material
- Resistant to mold and dirt accumulation
❌ Cons:
- Limited color options
- Requires skilled installation
2. EPDM Roofing
Ethylene Propylene Diene Monomer (EPDM) is a versatile rubber roofing membrane known for its adaptability and longevity.
✅ Pros:
- Excellent weather resistance
- Cost-effective
- Easy to install and repair
❌ Cons:
- Black EPDM absorbs heat, increasing cooling costs
- Requires regular maintenance to prevent leaks
3. Metal Roofing
Metal roofs are praised for their durability and long lifespan. They can withstand harsh weather conditions and are often made from aluminum, steel, or copper.
✅ Pros:
- Longevity of up to 50 years
- Fire-resistant
- Energy-efficient with reflective coatings
❌ Cons:
- Higher upfront cost
- Can be noisy during rain or hail
4. Modified Bitumen Roofing
Modified bitumen is an asphalt-based roofing material known for its flexibility and strength.
✅ Pros:
- Easy to maintain
- Good tensile strength
- Suitable for fluctuating temperatures
❌ Cons:
- Shorter lifespan compared to other types
- Susceptible to UV damage without a protective coating
5. Built-Up Roofing (BUR)
Built-up roofing consists of multiple layers of materials to create a durable and waterproof surface.
✅ Pros:
- Excellent UV protection
- Low maintenance
- Long lifespan
❌ Cons:
- Heavyweight may require additional structural support
- Longer installation time
Factors to Consider When Choosing a Commercial Roof Style
Choosing the right commercial roofing involves considering several factors:
- Climate and Weather: Consider the local climate and weather conditions to choose materials that can withstand them.
- Building Structure: The roof’s design should align with the building’s architecture and structural limitations.
- Energy Efficiency: Opt for roofs that enhance energy efficiency to reduce operational costs.
- Budget: Balance between upfront costs and long-term benefits to select a cost-effective solution.
- Durability and Maintenance: Evaluate the roof’s expected lifespan and maintenance requirements to ensure it meets your needs.
The Cost to Install a Commercial Roof
The cost of installing a commercial roof varies depending on the type of material, labor, and location. Here’s a rough estimate of costs per square foot:
- TPO Roofing: $5 to $8
- EPDM Roofing: $3.50 to $7.50
- Metal Roofing: $7 to $12
- Modified Bitumen Roofing: $4 to $8
- Built-Up Roofing (BUR): $5 to $9
Remember to also account for removal of the existing roof, labor charges, and any additional features or customizations.
How to Take Care of Your Commercial Roof
Regular maintenance is crucial to extend the lifespan of your commercial roof. Here are some tips:
- Routine Inspections: Conduct regular inspections to identify and address minor issues before they escalate.
- Clean Debris: Keep the roof clean from leaves, branches, and other debris to prevent water accumulation and damage.

- Maintain Drainage Systems: Ensure that gutters and downspouts are clear and functioning properly.
Signs That It Is Time for a Replacement
Knowing when to replace your commercial roof can save you from costly repairs. Look for these signs:
- Frequent Repairs: If you’re constantly fixing issues, it might be cheaper to replace the roof.
- Visible Damage: Cracks, blisters, and significant wear indicate the need for a new roof.
