What is a common application for a drip edge in architectural metal work?

A drip edge is an essential feature in architectural metal work, specifically designed to manage water flow and prevent moisture damage. Its primary function is to direct water away from surfaces, such as walls, roofs, and foundations. By creating a slight overhang at the edge of a roof or any surface, it ensures that rainwater drips off the edge rather than running down to the underlying materials.

Utilizing a drip edge effectively helps prevent water from pooling and potential leaks, which can lead to structural damage and deterioration over time. This proactive approach to water management enhances the longevity and durability of the building materials below.

In contrast, supporting heavy loads, facilitating air flow, and allowing for pipe insulation are not the primary functions of a drip edge. These options pertain to different aspects of construction and HVAC design not specifically related to the management of water runoff in architectural metal work.
