Buildings located in tornado-prone areas require roofing solutions that offer durability, resilience, and safety. Built-Up Roofing (BUR) systems have proven to be an excellent choice for such environments due to their robust construction and ability to withstand extreme weather conditions.
What Is Built-Up Roofing (BUR)?
BUR roofing is a traditional roofing system that consists of multiple layers of bitumen (asphalt or coal tar) alternated with reinforcing fabrics, typically felt or fiberglass. These layers are then covered with a protective surface, such as gravel or mineral granules, to shield against UV rays and physical damage.
Advantages of BUR Roofing in Tornado-prone Areas
- High Wind Resistance: The multiple layers and reinforced construction provide excellent resistance to high winds common in tornadoes.
- Durability: BUR systems are known for their long lifespan, often exceeding 20 years with proper maintenance.
- Waterproofing: The overlapping layers create a strong barrier against water intrusion, even during heavy rain associated with storms.
- Fire Resistance: The materials used in BUR are inherently fire-resistant, adding an extra layer of safety.
- Ease of Repair: Damaged sections can be easily repaired by adding additional layers, ensuring quick restoration after severe weather events.
Additional Considerations
While BUR roofing offers many benefits, it is essential to ensure proper installation and regular maintenance. Proper drainage systems should also be incorporated to prevent water pooling, which can weaken the layers over time.
Conclusion
For buildings in tornado-prone areas, BUR roofing provides a reliable and durable solution that enhances safety and longevity. Its proven resistance to extreme weather conditions makes it an ideal choice for protecting structures against the destructive power of tornadoes.
