Choosing the right roof is crucial for any commercial property. The types of commercial roofing available today vary in durability, cost, and maintenance needs. Whether you’re installing a new roof or replacing an old one, understanding the differences between materials can help you make an informed decision.
In this guide, we’re comparing commercial roofing types to highlight the advantages and drawbacks of each. Edmonton’s climate poses unique challenges, from harsh winters to summer storms, so selecting the right roofing system is essential for long-term durability and efficiency.
Why Choosing the Right Commercial Roof Matters
Selecting the best types of commercial roofing isn’t just about aesthetics—it impacts energy efficiency, maintenance costs, and longevity. The right roof can:
- Extend the building’s lifespan
- Reduce heating and cooling costs
- Protect against severe weather conditions in Edmonton
- Minimize the need for frequent repairs
Let’s take a closer look at the most common commercial roofing types and which might be best for your property.
Flat vs. Sloped Commercial Roofs
Before diving into specific materials, it’s important to understand the structural differences in types of commercial roofing.
- Flat roofs: Common in commercial buildings, flat roofs provide easy access for maintenance and HVAC installations. However, they require proper drainage to prevent water pooling.
- Sloped roofs: Less common for commercial properties, sloped roofs offer better drainage and longer lifespan but can be costlier to install.
Now, let’s explore the materials available for each style.
Comparing Commercial Roofing Types: Pros and Cons
1. Built-Up Roofing (BUR)
Best for: Flat roofs requiring durability and insulation.
Overview:
Built-up roofing consists of multiple layers of asphalt and reinforcing materials, topped with gravel or a reflective coating. This time-tested system is known for its longevity and resilience.
Pros:
✔ Highly durable and weather-resistant
✔ Provides good insulation for Edmonton’s extreme temperatures
✔ Fire-resistant and impact-resistant
Cons:
✘ Heavier than other roofing types, requiring strong structural support
✘ Installation can be time-consuming and labor-intensive
✘ Can be costly compared to single-ply systems
2. Modified Bitumen Roofing
Best for: Businesses needing flexible, waterproof roofing.
Overview:
Modified bitumen roofing is an upgraded version of BUR. It uses reinforced asphalt-based sheets that provide flexibility and durability, especially in fluctuating temperatures.
Pros:
✔ More flexible than traditional BUR, reducing the risk of cracking
✔ Strong resistance to extreme weather and UV exposure
✔ Relatively easy and quick to install
Cons:
✘ Can be prone to punctures if not properly maintained
✘ Requires professional installation to ensure durability
3. EPDM (Ethylene Propylene Diene Monomer) Roofing
Best for: Low-maintenance, cost-effective flat roofing.
Overview:
EPDM is a synthetic rubber membrane known for its longevity and energy efficiency. It’s commonly used in Edmonton due to its ability to withstand temperature fluctuations.
Pros:
✔ Lightweight and easy to install
✔ Resistant to UV damage, hail, and wind
✔ Cost-effective with minimal maintenance needs
Cons:
✘ Can shrink over time if not properly installed
✘ Seams may require sealing to prevent leaks
4. TPO (Thermoplastic Polyolefin) Roofing
Best for: Energy-efficient roofing with strong durability.
Overview:
TPO is a single-ply roofing system that reflects sunlight, making it an excellent option for energy-conscious businesses. It’s a popular choice in Edmonton’s commercial roofing market due to its balance of affordability and performance.
Pros:
✔ Highly reflective, reducing cooling costs in summer
✔ Resistant to chemical exposure and punctures
✔ Environmentally friendly and recyclable
Cons:
✘ Newer technology means long-term durability is still being tested
✘ Can be prone to seam failures if not installed correctly
5. PVC (Polyvinyl Chloride) Roofing
Best for: High-traffic roofs with strong chemical resistance.
Overview:
PVC roofing is a durable and flexible material with excellent resistance to chemicals, fire, and high winds. It’s commonly used in restaurants and factories where grease or chemicals may be present.
Pros:
✔ Strong resistance to fire, wind, and chemicals
✔ Long lifespan with minimal maintenance
✔ Heat-welded seams provide superior leak protection
Cons:
✘ More expensive than TPO and EPDM
✘ Can become brittle in extremely cold temperatures if not reinforced
6. Metal Roofing
Best for: Long-term investment with superior durability.
Overview:
Metal roofing is a great choice for commercial buildings looking for a long-lasting and durable roofing system. Materials such as aluminum, steel, and copper are commonly used.
Pros:
✔ Can last 40+ years with proper maintenance
✔ Excellent resistance to Edmonton’s snow and wind loads
✔ Energy-efficient with reflective coatings
Cons:
✘ Higher initial cost than membrane roofing systems
✘ Can be noisy during heavy rain or hailstorms
7. Green Roofing Systems
Best for: Businesses looking for environmentally friendly options.
Overview:
Green roofs incorporate vegetation and soil layers over a waterproofing system, offering insulation and energy efficiency. These are gaining popularity in urban areas due to their environmental benefits.
Pros:
✔ Reduces heat absorption, lowering energy costs
✔ Improves air quality and stormwater management
✔ Provides aesthetic and environmental benefits
Cons:
✘ Higher upfront installation and maintenance costs
✘ Requires structural reinforcement for added weight
Which Commercial Roof Type is Best for Edmonton?
Edmonton’s cold climate and heavy snowfall mean that types of commercial roofing need to be durable and weather-resistant. Some of the best options include:
- TPO and PVC roofing: Great for energy efficiency and durability.
- Metal roofing: Long lifespan and excellent in extreme weather.
- Modified bitumen and EPDM: Flexible and resistant to freeze-thaw cycles.
For businesses prioritizing sustainability, green roofing is a viable option, though it requires more maintenance.
Key Considerations When Choosing a Commercial Roof
Before making a decision, consider the following:
✔ Budget: Some materials have higher upfront costs but lower long-term maintenance needs.
✔ Lifespan: Metal roofing lasts decades, while single-ply membranes may require replacement sooner.
✔ Climate: Edmonton’s weather demands materials that can withstand snow, wind, and temperature fluctuations.
✔ Energy Efficiency: Reflective materials like TPO or metal coatings can reduce heating and cooling costs.
