1. What is a Built-Up Roof (BUR)?
A Built-Up Roof (BUR) is a traditional roofing system commonly used for commercial buildings. It consists of multiple layers of asphalt or bitumen combined with reinforcing fabric, often topped with gravel. The multiple layers create a durable, waterproof surface that can withstand harsh weather conditions. The gravel layer serves as a protective barrier, helping to prevent UV damage and physical wear. Understanding the structure of BUR is crucial in evaluating the total cost of this roofing system for your commercial property.

2.1 Material Costs
Materials for a BUR system typically include asphalt or bitumen, reinforcing fabrics (such as fiberglass or polyester), and gravel. The quality of materials you choose will significantly affect the overall cost. On average, material costs can range from $3 to $7 per square foot, depending on the quality and thickness of the layers used.
2.2 Labor Costs
Labor costs for installing a BUR with gravel are typically higher than other roofing systems due to the complexity of the installation process. Skilled labor is required to ensure that each layer is properly applied and that the gravel is distributed evenly. Labor costs generally range from $2 to $4 per square foot, with the total price increasing depending on the size of the project and the region.
2.3 Additional Costs
In addition to materials and labor, there may be additional costs for permits, equipment rental, and potential structural modifications. These extra costs could add another $1 to $3 per square foot. It is important to consult with a professional roofing contractor to get a more accurate estimate based on your specific building needs.
3. Advantages of a BUR with Gravel
Built-Up Roofs with gravel offer several advantages, making them a popular choice for commercial buildings. Here are some key benefits:
3.1 Durability and Longevity
BUR systems are known for their durability. When installed correctly, they can last 20 to 30 years, making them a long-term investment for commercial property owners. The gravel layer helps protect the roof from physical damage and UV rays, extending the roof’s lifespan.
3.2 Excellent Waterproofing
The multiple layers of a BUR system provide superior waterproofing. This makes BUR with gravel ideal for areas with heavy rainfall or snow. The gravel layer also serves as a ballast, preventing the roof from being damaged by wind uplift.
3.3 Low Maintenance
BUR roofs are relatively low maintenance compared to other types of commercial roofing. With proper installation, they require minimal repairs, making them cost-effective over time. The gravel layer also helps prevent the accumulation of debris on the roof, reducing maintenance needs.
4. Disadvantages of a BUR with Gravel
While there are many benefits to a BUR with gravel, it is not without its drawbacks. Here are some considerations to keep in mind:
4.1 High Initial Installation Cost
The cost of installing a BUR with gravel is generally higher than other roofing systems, especially in terms of labor and materials. For budget-conscious property owners, this can be a significant factor to consider. However, the long lifespan and low maintenance costs may offset this initial investment over time.
4.2 Weight
The gravel layer adds significant weight to the roof, which may require additional structural support. Buildings that were not originally designed to support this weight may need structural modifications, adding to the cost of the project.
4.3 Difficulty of Repair
If a section of the roof becomes damaged, repairing a BUR with gravel can be more complicated than other roofing systems. The gravel must be removed to access the damaged area, which can increase repair costs and labor time.
5. Long-Term Maintenance Costs for a BUR with Gravel
Although a BUR with gravel is known for being low-maintenance, it still requires periodic inspections and maintenance to ensure that it continues to perform well over the years. Some ongoing maintenance tasks include:
5.1 Regular Inspections
To maintain the longevity of the roof, regular inspections should be conducted to check for wear, tear, or any signs of water infiltration. Inspections should be scheduled every 2 to 3 years, or more frequently in areas with harsh weather conditions.
5.2 Gravel Replacement
Over time, the gravel on a BUR roof may become displaced or worn down, and it may need to be replaced to ensure the roof remains protected. Gravel replacement is typically required every 5 to 10 years, depending on the environment.
5.3 Repair Costs
If damage occurs, such as leaks or punctures, the gravel layer must be removed to access the affected area. This can increase the cost of repairs compared to other roofing systems. Repair costs will vary depending on the extent of the damage.
