Built-Up Roofing
What is BUR?
Built-Up Roofing (BUR) is a traditional and highly durable roofing system that has been used for over a century in commercial and industrial applications. BUR systems consist of multiple layers of roofing material, typically asphalt or coal tar, combined with reinforcing fabrics such as fiberglass or polyester to create a robust, watertight barrier. These layers are built up in successive applications to provide long-lasting protection against the elements.
BUR roofs are designed to offer superior strength, durability, and waterproofing, making them ideal for commercial buildings with flat or low-slope roofs. The multi-layer construction enhances the system’s resistance to UV rays, weathering, and physical damage, ensuring a reliable roof for many years.
How Does a BUR Roof System Work?
A typical BUR system consists of multiple layers of roofing felt (such as fiberglass or polyester) that are coated with a bitumen material (asphalt or coal tar). The layers are built up one on top of the other, and the bitumen is heated and applied to bond each layer together. Once the layers are applied, a final protective layer is added to shield the roof from UV rays, foot traffic, and other environmental factors.
The resulting system is tough, waterproof, and capable of withstanding extreme weather conditions. BUR roofs can also be topped with additional protective coatings or gravel to enhance durability and reflectivity.
Benefits of BUR Roofing
- Exceptional Durability: BUR roofs are highly resistant to weathering, UV rays, and physical damage due to their multi-layer construction. This makes them an ideal solution for buildings exposed to harsh climates or physical wear.
- Waterproofing: The multiple layers of bitumen and reinforcing fabric provide excellent waterproofing, making BUR systems highly effective in preventing leaks and water damage.
- Long Lifespan: BUR systems are known for their longevity, with proper installation and maintenance potentially extending the life of the roof for 30 years or more.
- Low Maintenance: Once installed, BUR systems require minimal maintenance, with periodic inspections and repairs being enough to maintain their effectiveness over time.
- Thermal Insulation: The layers of the BUR system provide a degree of thermal insulation, helping to regulate indoor temperatures and reduce energy costs for heating and cooling.
- Fire Resistance: BUR systems offer excellent fire resistance, making them a safe option for commercial buildings looking to enhance fire protection.
When to Use a BUR Roof System
BUR roofing is ideal for:
Commercial Buildings
Offices, retail spaces, warehouses, and manufacturing facilities with flat or low-slope roofs benefit from the durability and protection BUR provides.
New Construction
BUR roofing is an excellent choice for new builds, especially when long-lasting protection and low maintenance are priorities.
Re-Roofing
If your existing roof is aging or showing signs of damage, BUR can be an effective solution for replacing the roof with a more durable, reliable system
High-Traffic Roofs
Because of its toughness and resilience, BUR is an ideal option for commercial buildings that require roof access for maintenance or equipment.
Harsh Climates
BUR systems are highly effective in regions with extreme weather, whether hot, cold, or humid, due to their strength and multi-layer design.
BUR Roof Repairs and Maintenance
While BUR roofing systems are low-maintenance, regular inspections and minor repairs are essential for extending the lifespan of the roof. Here’s what to consider for maintaining your BUR roof:
Check your BUR roof regularly for signs of damage, such as punctures, cracks, or worn-out seams. Early detection of issues can prevent larger, costlier repairs.
Clean the surface of the BUR system to remove debris such as leaves, dirt, and branches. A clean roof helps ensure that water drains properly and prevents additional damage.
If the roof begins to show signs of wear, repairs may involve adding new layers of bitumen or reinforcing fabric to restore the roof’s protective qualities.
BUR roofs should be flood-tested periodically to ensure that no leaks have developed beneath the layers of the system. This is particularly important in areas prone to heavy rainfall.
The protective top layer of gravel or coatings may need to be replenished over time to maintain the roof’s reflectivity and protect it from UV damage.
