Introduction to Built-Up Roofing (BUR)
Built-Up Roofing Systems, commonly known as BUR, are a staple in the roofing industry, especially for buildings with flat or low-sloped roofs. This roofing type is renowned for its resilience and efficiency, making it an ideal choice for commercial and industrial applications.
Composition and Types of BUR
BUR is composed of alternating layers of bitumen (asphalt) and reinforcing fabrics, typically made of fiberglass. This composition is then topped with a layer of fine gravel or small stones, enhancing its durability and weather resistance. There are several types of BUR, each with unique characteristics:
- Hot Built-Up Roof: In this method, bitumen is heated and liquefied during installation, requiring skilled handling due to the heated materials.
- Cold Built-Up Roof: Here, cooled bitumen is used like an adhesive, applied or sprayed, offering a safer and more environmentally friendly option.
- Ballasted Asphalt Built-Up Roof: This type uses heavy stones on the surface layer, eliminating the need for fastening the lower layers to the roof structure.
Advantages of BUR
- Weather Resistance: BUR roofs are highly resistant to extreme weather conditions, thanks to the tar or coal tar in their composition, which is fire-resistant. The tight bitumen layer effectively repels water, while the fiberglass coating adds to the roof’s sturdiness.
- Energy Efficiency: The reflective coating on BUR systems protects against UV rays, helping to keep the building cool and reducing energy costs.
- Low Maintenance: BUR roofs require less frequent maintenance due to their durability and the large sheet installation method, which is less prone to damage compared to shingles.
Installation and Longevity
The installation of a BUR involves laying down a base sheet, followed by the bitumen and ply sheets, and finally, the surfacing material. This method ensures a sturdy and safe roofing system. The lifespan of a BUR can range from 15 to 40 years, depending on the climate and quality of installation. For optimal performance, it’s crucial to engage a professional roofing contractor.
