🤔 What is Built Up Roofing

Built up roofing, often referred to as BUR, is a layered roofing system commonly used on flat or low-slope commercial buildings. It consists of alternating layers of bitumen (asphalt or coal tar) and reinforcing materials, like fiberglass or organic felts, topped with a layer of gravel or a reflective coating.

This roofing system has been widely used for over 100 years, proving its reliability and resilience in protecting buildings from the harshest weather conditions.

How Built Up Roofing Is Constructed

• Base Layer: A secure base layer is installed to provide a strong foundation and adhere to the building.
• Reinforcing Layers: Alternating layers of bitumen and reinforcing fabric are added for waterproofing and durability.
• Top Layer: The final layer of gravel or protective coating protects against UV rays, weather, and impact, extending the roof’s lifespan.

⭐️ 6 Top Benefits of Built Up Roofing

Built-up roofing is a durable and cost-effective solution for flat or low-sloped roofs. It provides excellent waterproofing, UV protection, and long-lasting performance, making it ideal for commercial and industrial buildings.

1. Exceptional Durability

Built up roofing is renowned for its long-lasting performance and durability, making it a popular choice for commercial properties. Its layered construction, which typically combines alternating layers of bitumen and reinforcing fabrics, creates a robust barrier capable of withstanding some of the harshest environmental conditions. Whether it’s heavy rains, strong winds, or prolonged UV exposure, built up roofing can maintain its integrity over time. This resilience makes it ideal for properties in areas prone to extreme weather, ensuring your building remains protected year-round.

2. Waterproof Protection

The multiple layers of bitumen used in built up roofing provide exceptional waterproofing, effectively sealing your building from moisture penetration. Water damage can be one of the most costly issues for businesses, leading to structural damage, mold growth, and expensive repairs. Built up roofing eliminates these risks by creating a seamless, watertight surface that prevents leaks and protects your assets. With this level of protection, you can have peace of mind even during prolonged periods of heavy rain or snowfall.

3. Low Maintenance

Built up roofing systems are designed to be durable and low-maintenance, making them an excellent long-term investment. Once installed, these roofs require only periodic inspections and minor repairs to remain in optimal condition. Unlike other roofing systems that may demand frequent upkeep, built up roofing minimizes the need for constant attention, saving business owners both time and money. By scheduling routine inspections, you can quickly address any minor issues before they escalate, ensuring your roof stays in great shape for decades.

4. Cost-Effectiveness

While the upfront installation cost of built up roofing may be higher than some alternatives, its long-term benefits far outweigh the initial investment. The durability, minimal maintenance requirements, and extended lifespan of built up roofing translate into significant cost savings over time. Businesses can avoid the frequent repairs and replacements often associated with less durable roofing options. Additionally, its ability to withstand wear and tear for decades ensures that built up roofing delivers consistent value, making it a smart and cost-efficient choice for businesses focused on long-term sustainability.

5. Thermal Efficiency

Built up roofing contributes to better thermal efficiency for your building, which can help reduce energy consumption and lower utility bills. The top layer of the roof, which often includes gravel or a reflective coating, acts as an insulating barrier. This insulation helps regulate indoor temperatures by keeping heat out during the summer and retaining warmth during the winter. As a result, businesses can enjoy a more comfortable environment for employees and customers while reducing reliance on heating and cooling systems, ultimately saving on energy costs.

6. Fire Resistance

Fire safety is a critical consideration for any building, and built up roofing offers an added layer of protection. Many built up roofing systems incorporate fire-resistant materials, such as fiberglass or mineral-surfaced cap sheets, into their layered design. This fire resistance significantly reduces the risk of a fire spreading across the roof, helping to safeguard your building and its occupants. By choosing built up roofing, businesses can enhance their overall fire safety measures while also potentially lowering insurance premiums due to the reduced fire risk.

🛠️ How Built Up Roofing is Installed

The process of installing built up roofing is meticulous and best handled by experienced professionals. Here’s a step-by-step look:

Inspection

The process begins with a detailed inspection of the roof structure. This step ensures that the building’s roof is strong enough to support the Built-Up Roofing (BUR) system. Engineers and contractors assess the condition of the roof deck, checking for any damage, weak spots, or structural issues that need to be addressed before installation begins.

Preparation

Once the roof passes inspection, the preparation phase begins. A base layer is installed to create a secure and stable foundation for the BUR system. This base layer helps protect the underlying structure while ensuring a smooth surface for the subsequent layers. Proper preparation is key to ensuring the long-term performance of the roof.

Layering

The core of the BUR system involves alternating layers of bitumen (asphalt or coal tar) and reinforcing materials like fiberglass or felt. These layers are carefully applied to build a strong, weather-resistant roofing system. Each layer is added with precision to ensure proper adhesion and protection against moisture, UV rays, and other environmental factors.

Finishing Touches

To complete the BUR system, a top layer is applied. This final layer often consists of gravel or a protective coating designed to enhance durability and functionality. The gravel provides additional protection from the elements, including UV rays and physical damage, while also improving the roof’s appearance. Alternatively, a reflective coating may be used to improve energy efficiency.

Final Inspection

Before the project is finalized, a thorough inspection is conducted to ensure the roofing system meets all quality standards. This step verifies that the BUR system has been properly installed, with no gaps, weaknesses, or overlooked details. The final inspection ensures the roof is ready to provide long-lasting performance and protection.
