Commercial flat roofing systems play a crucial role in protecting businesses across Wisconsin and Illinois. Whether you're a new property owner or have managed a commercial building for years, understanding your roofing options helps you make informed decisions when repairs or replacements become necessary. Flat roofs, in particular, demand regular maintenance due to their unique structure, making timely care and informed choices essential to avoid costly water damage.
This guide explores the most common types of commercial flat roofing systems, highlighting their benefits, downsides, and lifespans. Additionally, we’ll share why TPO and PVC roofing systems are among the best choices for durability and weather resistance.
What Are Commercial Flat Roofing Systems?
Unlike pitched roofs, flat roofs are level with only a slight slope for drainage. They are widely used for commercial properties because of their cost-effectiveness, simplicity, and suitability for HVAC systems or rooftop amenities. However, they require regular inspections and maintenance due to potential water pooling and wear.
Here’s an overview of the most popular commercial flat roofing options to help you decide what’s right for your business.
TPO Roofing
TPO (Thermoplastic Polyolefin) is a popular single-ply roofing system made of a durable membrane that is heat-welded at the seams.
Benefits of TPO Roofing
Durability: TPO is highly resistant to tears, punctures, and fire.
Energy Efficiency: Its reflective surface helps reduce cooling costs in summer.
Flexibility: TPO expands and contracts with temperature changes, making it ideal for Midwest climates with cold winters.
Longevity: When properly maintained, TPO roofs typically last 20–30 years.
Because of its ability to withstand Wisconsin and Illinois’ cold winters while also reflecting heat in summer, TPO is a top choice for many businesses in the area.
PVC Roofing
PVC (Polyvinyl Chloride) roofing is another single-ply option that features two layers of PVC reinforced with a polyester core.
Advantages of PVC Roofing
UV Resistance: The material resists sun damage, extending its lifespan.
Lightweight and Flexible: It’s easy to install and works well in various conditions.
Chemical Resistance: PVC stands up to grease and other chemicals, making it ideal for restaurants and factories.
Customizable Appearance: Available in various colors and thicknesses to suit both esthetics and performance needs.
Longevity: With proper maintenance, PVC roofs also last up to 30 years.
PVC roofing systems not only provide excellent durability but also allow for design flexibility, making them a practical and stylish option for flat roofs.
Modified Bitumen Roofing
Modified bitumen roofing is made by combining asphalt with a polymer for added flexibility. Applied in layers, it’s a more traditional choice for commercial flat roofs.
Benefits of Modified Bitumen Roofing
Layered Protection: Multiple layers increase its durability against weather.
Suitable for Various Climates: Performs well in both hot and cold environments.
Budget-Friendly: Often more affordable than other flat roofing options.
Downsides
Heat Retention: This material absorbs heat, raising cooling costs in the summer.
Water Pooling: Flat surfaces can accumulate water more easily, requiring frequent inspections.
Maintenance: It has a shorter lifespan (15–20 years) compared to TPO and PVC.
While it’s a cost-effective option, frequent maintenance and shorter durability make modified bitumen less ideal for long-term investments.
Built-Up Roofing (BUR)
Built-up roofing (BUR) is one of the oldest flat roofing methods. It uses layers of asphalt and reinforcing ply sheets, creating a durable barrier against the elements.
Advantages of BUR Systems
Cost-Effective: Among the least expensive commercial roofing solutions.
Thick Layers: Multiple layers provide extra protection against damage.
Drawbacks
Heat Absorption: Similar to modified bitumen, BUR roofs can make buildings warmer.
Frequent Issues: Problems like pooling, cracking, or blistering occur more regularly.
Shorter Lifespan: Typically lasts about 15–20 years with regular maintenance.
While the affordability of BUR systems appeals to some, their higher maintenance requirements make them less practical compared to modern alternatives like TPO and PVC.
