Single-Ply Roofing vs Built Up Roofing: Cost and Performance Comparison
Understanding Single-Ply Roofing Systems
Single-ply roofing systems use a single layer of manufactured membrane to create a waterproof barrier. The most common materials include TPO, PVC, and EPDM. These membranes are produced in large sheets and installed with minimal seams, which helps speed up installation and reduce potential leak points.
Because of their flexibility and efficiency, single-ply systems are widely used on commercial buildings throughout the Midwest. Their adaptability makes them a strong option for a variety of building types, from warehouses to office facilities.
What Is Built up Roofing (BUR)?
Built up roofing, often called “tar and gravel,” is a traditional system made of multiple layers of asphalt (bitumen) and reinforcing fabrics. These layers are topped with gravel or a reflective coating to create a durable, multi-layer barrier.
BUR has been used for decades and remains a trusted option for commercial properties that require added durability and redundancy.
Cost Comparison: Upfront vs Long-Term Value
Cost is one of the biggest decision factors for property owners in South Bend. Single-ply roofing systems typically range from about $5 to $11 per square foot depending on the material selected. Built up roofing systems generally fall between $6 and $10 per square foot installed.
While initial costs can overlap, the real difference comes from installation efficiency and lifecycle expenses. Single-ply systems install quickly, often within a few days, which helps reduce labor costs and minimize disruption to daily operations. In contrast, built up roofing requires multiple layers and more time to install, increasing labor demands.
Over time, single-ply systems can also contribute to energy savings. Reflective membranes such as TPO and PVC reduce heat absorption, which can lower cooling costs during warmer months in South Bend.
Performance Comparison
Durability and Puncture Resistance
Built up roofing systems are known for their strength due to their multi-layer construction. If one layer becomes damaged, additional layers continue to provide protection. This makes BUR a strong choice for roofs that experience heavy foot traffic or house rooftop equipment.
Single-ply membranes are thinner, which can make them more vulnerable to punctures. However, modern advancements in materials have improved their durability, making them reliable for most commercial applications.
Energy Efficiency
Single-ply roofing systems, especially lighter-colored membranes, reflect sunlight and help maintain lower roof surface temperatures. This can reduce strain on HVAC systems and improve overall energy efficiency.
Built up roofing systems can be enhanced with reflective coatings, but without them, they tend to absorb more heat. In a climate like South Bend, where both cooling and heating costs matter, energy performance should be evaluated based on building use.
Installation and Disruption
One of the biggest advantages of single-ply roofing is its fast installation. Large membrane sheets and streamlined installation methods allow projects to be completed quickly, reducing downtime for businesses.
Built up roofing takes longer to install due to its layered construction. The process can involve more intensive labor and may create temporary disruptions for building occupants.
Maintenance and Repairs
Single-ply roofing systems are generally easier to maintain and repair. Damaged sections can often be patched or heat-welded efficiently, reducing repair time and costs.
Repairs for built up roofing systems can be more complex because multiple layers must be addressed. While the system is durable, restoration work can require more time and specialized labor.

Lifespan
Both roofing systems offer comparable lifespans when properly installed and maintained. Single-ply roofs typically last between 20 and 35 years depending on the material. Built up roofing systems generally last 20 to 30 years or more.
The difference lies in how they perform over time. Single-ply systems rely on the integrity of the membrane, while built up roofing benefits from layered protection.
Which Roofing System Is Best?
The right choice depends on your building’s structure, usage, and long-term goals.
Single-ply roofing is often the better option for property owners who prioritize faster installation, improved energy efficiency, and easier maintenance. Its lightweight design also makes it suitable for buildings with structural limitations.
Built up roofing is ideal for those who need enhanced durability and resistance to wear. Its layered design provides added protection, making it well-suited for high-traffic roofs or buildings with heavy rooftop equipment.
