The Importance of Roof Inspection
Before choosing a roofing option, a thorough roof inspection is essential. This helps in understanding the current condition of your roof and identifying any underlying issues that need to be addressed.
RoofCrafters, with nearly three decades of experience, emphasize the importance of this initial step. A detailed inspection can guide you towards the most suitable roofing type for your specific needs.
“A comprehensive roof inspection not only identifies existing issues but also helps in planning for future maintenance and repairs,” says a RoofCrafters expert.
Conclusion
Understanding your commercial roofing options—whether it’s flat, low slope, or steep slope—can significantly impact the longevity and efficiency of your building. Proper inspection and informed decision-making are key to selecting the right roof type for your commercial property.
Next, we’ll dive into the Top 6 Commercial Roofing Types, exploring single-ply roofing, modified bitumen, built-up roofing, metal roofing, green roofing, and asphalt shingles.
Top 6 Commercial Roofing Types
Single-Ply Roofing: TPO, PVC, & EPDM
Single-ply roofing is among the most popular options for commercial buildings, especially flat roofs. TPO (Thermoplastic Polyolefin), PVC (Polyvinyl Chloride), and EPDM (Ethylene Propylene Diene Monomer) are the key players in this category.
TPO is known for its energy efficiency, thanks to its reflective surface. It’s also resistant to UV rays and chemicals. PVC is another excellent choice, especially for roofs exposed to harsh weather or chemicals. It offers strong resistance to moisture and fire. EPDM, a durable synthetic rubber, stands out for its resistance to extreme temperatures and UV rays. It’s cost-effective and easy to install.
Pros:
- Energy-efficient
- Durable
- Resistant to chemicals and UV rays
Cons:
- Can be punctured easily
- Quality varies, so choose reputable manufacturers

Next, we’ll discuss the Key Factors to Determine the Best Commercial Roof, including lifespan, durability, and energy efficiency.
Key Factors to Determine the Best Commercial Roof
Choosing the right roof types for commercial buildings involves considering several key factors. Here’s what you need to know:
Lifespan
The lifespan of your roof is crucial. Metal roofing, for instance, can last between 40 to 60 years, while Built-Up Roofing (BUR) typically lasts around 20 to 30 years. Green roofs can also stretch to 50 years with proper care. Always consider how long you need the roof to last.
Durability
Durability is about how well the roof can withstand environmental stress and foot traffic. Metal roofing is highly durable and fire-resistant, but it can corrode. Modified Bitumen Roofing is great for high foot traffic areas due to its multiple layers. Single-ply membranes like TPO and PVC are durable but can be punctured easily, so they might not be ideal for roofs with heavy equipment.
Energy Efficiency
Energy efficiency can save you money on heating and cooling. TPO and PVC roofs are known for their reflective properties, reducing cooling costs. Green roofs provide natural insulation, maintaining indoor temperatures. Even metal roofs can be energy-efficient, especially if they are light-colored or have reflective coatings.
Cost
Cost varies widely among different roofing types. Asphalt shingles are the most affordable, costing between $1.50 and $5.50 per square foot. Metal roofing and green roofs have higher upfront costs but offer long-term savings through durability and energy efficiency. Always balance initial costs with long-term benefits.
Foot Traffic
If your roof will have a lot of foot traffic, choose materials that can handle it. Modified Bitumen and BUR systems are excellent choices here. They are designed to withstand the wear and tear of frequent access, unlike single-ply membranes which are more prone to punctures.
Weather Conditions
Local weather plays a big role in your decision. In areas with heavy rainfall or snow, metal roofing and PVC membranes are excellent choices due to their water resistance. For hot climates, TPO and green roofs are ideal for their cooling properties. BUR systems are UV-resistant and can be coated to reflect heat, making them versatile for various climates.
R-Value and Insulation
The R-value measures thermal resistance. Higher R-values mean better insulation. Tapered insulation in flat roofs not only improves drainage but also boosts R-value, enhancing energy efficiency. Green roofs and metal roofs with added insulation can also provide excellent thermal resistance.
Making the Right Choice
Balancing these factors will help you choose the best roof for your commercial building. For instance, if energy efficiency and long lifespan are your top priorities, a metal roof or green roof might be the best fit. If cost is a constraint, asphalt shingles or BUR could be more suitable.
Next, we’ll address some frequently asked questions about roof types for commercial buildings, to help you make an even more informed decision.
