What can be a consequence of using inadequate flashings on modified bitumen systems?

• A. Improved water resistance
• B. Increased risk of leaks
• C. Lower installation costs
• D. Enhanced thermal performance

Answer: (B)

Using inadequate flashings on modified bitumen systems can lead to an increased risk of leaks. Flashings are critical components of roofing systems, designed to direct water away from vulnerable areas where the roof surface meets walls, chimneys, or other structures. Properly installed flashings help to create a watertight seal and protect these transitions from moisture intrusion. When flashings are inadequate—whether due to poor installation, insufficient material quality, or improper design—they fail to provide the necessary protection. This can result in water pooling or seeping into the roofing system, ultimately leading to leaks. Over time, these leaks can cause significant damage to the roof assembly, as well as to the building's interior, insulation, and structural components. Consequences like improved water resistance, lower installation costs, or enhanced thermal performance are not characteristics associated with inadequate flashings. Instead, they highlight the importance of proper flashing installation as a means of safeguarding against moisture issues in modified bitumen systems.
