What Is Drip Edge?

Nov 29, 2022

Welcome to Bio-One Atlanta's comprehensive guide on drip edge – an essential component in the roofing industry. In this article, we will explore the importance of drip edge, its benefits, and why it significantly contributes to the overall protection and durability of residential and commercial properties.

The Basics of Drip Edge

Drip edge is a metal flashing that is installed along the edges of a roof, providing a barrier between the roof deck and the fascia board. It is typically made of aluminum or galvanized steel and comes in various shapes and sizes to suit different roof designs. The primary purpose of drip edge is to prevent water from seeping into the underlying roofing system.

Importance of Drip Edge

Drip edge plays a crucial role in protecting your property from potential water damage. By directing water away from the fascia board and edge of the roof, it helps prevent moisture-related issues such as rot, mold, and decay. Additionally, drip edge enhances the overall aesthetics of your roof by creating a clean and finished look.

Benefits of Drip Edge

1. Deflects Water: Drip edge acts as a shield, redirecting rainwater away from vulnerable areas. It ensures that water flows into the gutters or eavestroughs and avoids pooling on the roof or infiltrating the underlying structure.

2. Protects Fascia Board: The fascia board is susceptible to water damage, which can lead to structural issues. Drip edge prevents water from reaching the fascia, extending its lifespan and preserving the integrity of your roof.

3. Preserves Siding: Without proper water redirection, excess moisture can seep behind the siding, causing damage and facilitating the growth of mold and mildew. Drip edge helps maintain the durability and appearance of the siding by keeping it dry.

4. Prevents Ice Dams: In colder climates, drip edge plays a vital role in combating ice dams. By preventing ice and snow from accumulating at the roof's edge, it minimizes the risk of water intrusion and subsequent damage to the interior of your property.

Installation of Drip Edge

Correct installation of drip edge is crucial to ensure optimal performance and protection. It should be installed during the early stages of roof construction, before the underlayment and shingles are applied. The angle of the drip edge should be slightly overhanging the roof edge to facilitate water runoff.

It is recommended to hire a professional roofing contractor, like Bio-One Atlanta, to install the drip edge properly. They have the expertise and experience to ensure the precise placement and sealing of the flashing, guaranteeing its effectiveness in preventing water damage.
