Product Application
Drip Edge
BELCO’s drip edge trim application creates an impenetrable shield against moisture damage, water staining, and pest intrusion protecting the integrity and appearance of rooflines.

BELCO XT® Drip Edge
Moisture Intrusion Insurance
Drip edge is a small but important trim component designed to shield gable-end barge boards from moisture intrusion. Installed at the top of the bargeboard, it creates a secure attachment point for flashing while maintaining a small gap that prevents water from running down the face of the barge. This not only protects the structure from rot and damage caused by excessive moisture, but also enhances the home’s exterior with clean shadow lines and architectural detail.
Too often, gable ends are finished without a drip edge, leaving the bargeboard exposed to wind-driven rain and runoff. Over time, this leads to streaking and eventual decay. When Belco XT Trim is used for drip edge applications, these issues are eliminated because drip edge acts as a durable moisture barrier while blending with and enhancing exterior trim design.
FORM MEETS FUNCTION
Details, Longevity, and Closing the Gap
Regional building codes vary, and sometimes altogether neglect drip edge requirements. However, without a proper drip edge, gaps can form between the roof decking and fascia, creating entry points for pests and unwanted moisture, which may lead to pesky infestations and rot.
Belco XT drip edge is thoughtful in design, beauty, and performance wrapped in one solution. Engineered to follow the precise angle of the gable, it creates an essential gap between the flashing and the bargeboard. This simple yet effective design detail ensures long-term durability by acting as a steadfast moisture barrier. Every innovative element from the secure attachment to the cap flashing, works together to close the gap between durability and design excellence, keeping rooflines looking pristine year after year.
INSTALLATION BEST PRACTICES
Application & Installation Information
Belco XT drip edge trim is designed for simple and straightforward installation. Align the drip edge with the top edge of the bargeboard, following the natural angle of the gable end. Secure the drip edge using appropriate fasteners at regular intervals to ensure a stable attachment point for the cap flashing. The drip edge creates the necessary one-inch gap between the flashing and the bargeboard. Once the drip edge is properly secured, install the cap flashing over it to provide additional protection.
