Which gauge is considered standard for exterior flashing?

• A. 24
• B. 26
• C. 28
• D. 30

Answer: (B)

Gauge measures the thickness of flashing metal. For exterior flashing, you want enough thickness to resist tearing and denting from nails, wind, and weather, while still being flexible enough to form around corners and details.26 gauge hits that balance: it’s thick enough to hold up under exterior conditions and easy to shape into flashing so it can seal joints effectively. Thicker options like 24 gauge add unnecessary stiffness and cost for typical flashing needs, while thinner options (28 or 30 gauge) are more prone to damage and deformation in outdoor use. So, 26 gauge is the standard for exterior flashing.
