Built-Up Covering (BUR)
Comprising multiple layers of tar and gravel, BUR systems are known for their durability and cost-effectiveness. Built-Up Roofing, often referred to simply as BUR, is a traditional roofing system that consists of multiple layers (or "plies") of roofing felt, asphalt, and a top layer of gravel or mineral granules. This multi-layered approach creates a robust, watertight barrier that is highly effective at keeping the elements out.
The Strengths Of BUR
Durability and longevity:
One of the standout features of BUR is its exceptional durability. The multiple layers of roofing material create a strong, resilient surface that can withstand harsh weather conditions, heavy foot traffic, and even minor impacts. A well-maintained BUR roof can last 20 to 30 years or more, providing excellent long-term value for your investment.
Excellent Waterproofing:
The overlapping layers in a BUR system provide superior waterproofing. This is particularly important for flat or low-slope roofs, where water tends to pool and drainage can be a challenge. The asphalt used in BUR is also inherently waterproof, adding an extra layer of protection against leaks.
Low Maintenance:
Once installed, BUR roofs require relatively little maintenance compared to other roofing systems. Regular inspections and minor repairs can keep your BUR roof in excellent condition, reducing the likelihood of significant issued down the line.
Fire Resistance:
BUR systems are highly fire-resistant. The layers of asphalt and gravel create a fire barrier that can help protect your building in the event of a fire, potentially preventing extensive damage.
Energy Efficiency:
The reflective properties of the top gravel layer can help reduce heat absorption, keeping your building cooler in the summer and reducing energy costs. Additionally, BUR systems can be coated with reflective materials to enhance their energy efficiency further.
