What gauge is standard for exterior flashing?

• A. 24
• B. 26
• C. 28
• D. 30

Answer: (B)

The standard gauge for exterior flashing is commonly 26 gauge. This gauge strikes a good balance between durability and weight, making it suitable for outdoor elements where it may face the rigors of weather conditions such as rain, snow, and wind. Flashing serves to divert water away from critical areas in the building, preventing leaks and water damage. Using a heavier gauge like 24 can be more robust but might be overkill for certain applications and can increase overall material costs. Conversely, using a lighter gauge like 28 or 30 may not provide the same level of protection, as they can be more prone to bending and wear over time, particularly in areas exposed to harsh weather. Therefore, 26 gauge is often preferred for its balance of strength and manageability in various flashing applications.
