What is recommended in terms of fastener maintenance in low slope roofing systems with built-up roof membranes?

1. A Puncture holes for drainage

2. B Replace all fasteners every year

3. C Resurface BUR rather than patching

4. D Increase fastener spacing

The correct answer is: C Resurface BUR rather than patching

The recommended approach for maintaining fasteners in low slope roofing systems with built-up roof (BUR) membranes is to resurface the BUR rather than patching. This method is preferred because resurfacing can provide a more uniform and effective protective layer over the entire roofing system compared to localized patching, which may not address potential widespread issues that could lead to leaks or further degradation of the roof membrane. Resurfacing also allows for a comprehensive inspection and maintenance of the entire roofing surface, ensuring that any underlying problems can be identified and resolved. This proactive approach can extend the life of the roofing system and maintain its integrity over time. Puncture holes for drainage could potentially create weaknesses in the membrane, and replacing all fasteners every year might be unnecessary and overly burdensome. Increasing fastener spacing may compromise the holding capability of the roof system, leading to potential failures under stress from weather or other factors. Thus, selecting resurfacing as the preferred maintenance method aligns with best practices in roofing care and longevity.
