What is the minimum drip edge overlap at the eaves and gables of shingle roofs?

1 inch
2 inches
3 inches
4 inches

The correct answer is: 3 inches

The minimum drip edge overlap at the eaves and gables of shingle roofs is set to ensure proper water management and to prevent any potential water infiltration into the roofing system. An overlap of 3 inches is specified to provide a suitable barrier against wind-driven rain and to direct water away from the underlying structures effectively. This helps in maintaining the integrity of the roof and protects the roofing materials and components from rot and damage over time. The other options suggest overlaps that may not provide sufficient protection against water seepage in adverse weather conditions. A smaller overlap could lead to vulnerabilities where water can penetrate, potentially compromising the roof's performance and durability. Thus, adhering to the 3-inch minimum for drip edge overlap helps uphold construction standards and prolongs the lifespan of the roofing system.
