Low-sloped Built-Up Roofing (BUR) systems are a popular choice for commercial buildings due to their durability and cost-effectiveness. However, as with any roofing system, proactive maintenance and strategic upgrades can significantly extend its lifespan and minimize costly repairs. One effective strategy gaining traction in the roofing industry is the application of liquid-applied systems over existing BUR roofs, offering enhanced protection and longevity.
Understanding Low-Sloped BUR Roofing
Built-Up Roofing (BUR) systems consist of multiple layers of bitumen alternated with reinforcing fabrics, typically installed on low-sloped or flat roofs. These systems are known for their resilience and ability to withstand various weather conditions, making them suitable for Arizona’s climate.
Benefits of Liquid-Applied Systems
Liquid-applied roof coatings provide a seamless, waterproof barrier that adheres tightly to the existing BUR layers. Here are key advantages:
- Enhanced Protection: Liquid-applied coatings form a continuous membrane that prevents water infiltration, reducing the risk of leaks and extending the roof’s lifespan.
- Reflectivity: Many liquid-applied coatings are designed to be highly reflective, reducing heat absorption and lowering cooling costs during hot Arizona summers.
- Flexibility: These systems can accommodate roof movements and structural shifts, adapting to temperature changes without compromising performance.
Preventative Installation of Liquid-Applied Systems
Installing a liquid-applied system before the BUR roof shows signs of leaks or damage is crucial. Proactive installation helps:
- Preventive Maintenance: By reinforcing the roof’s waterproofing before issues arise, property owners avoid costly repairs associated with water damage and structural deterioration.
- Cost Efficiency: Early intervention with liquid-applied coatings is often more cost-effective than reactive repairs or full roof replacements.
Importance of Ongoing Roof Maintenance
Regular maintenance plays a pivotal role in maximizing the lifespan of low-sloped BUR roofing systems:
- Inspections: Scheduled inspections allow for early detection of potential issues such as cracks, blisters, or membrane deterioration.
- Cleaning and Debris Removal: Keeping the roof clean of debris and vegetation prevents water ponding and extends the effectiveness of liquid-applied coatings.
- Reapplication of Coatings: Periodic reapplication of liquid-applied coatings ensures continued protection and reflects changing environmental conditions.
Conclusion
Incorporating a liquid-applied system over low-sloped BUR roofing can significantly enhance durability and performance, particularly in Arizona’s climate. Installing these systems proactively, before leaks occur, prevents costly damage and reinforces waterproofing capabilities. Coupled with ongoing roof maintenance, including inspections and coatings reapplication, property owners can effectively safeguard their investment and enjoy prolonged roof longevity.
