As a seasoned roofing contractor with decades of experience, I’ve seen firsthand the importance of proper roof installation and maintenance. One crucial element that often gets overlooked but plays a significant role in protecting your roof and home is drip edge flashing. In this guide, I’ll walk you through everything you need to know about drip edge flashing, from its purpose to installation tips and examples.

Understanding Drip Edge Flashing

What is Drip Edge Flashing?

Drip edge flashing is a metal or plastic strip installed along the edges of a roof to direct water away from the fascia and into the gutter system. It serves as a barrier between the roofing material and the edge of the roof, preventing water damage and prolonging the life of the roof.

Why is Drip Edge Flashing Important?

Properly installed drip edge flashing helps prevent water from seeping under the roofing material, which can lead to rot, mold, and other forms of water damage. It also helps protect the fascia board and siding from moisture-related issues, such as rot and decay.

How Does Drip Edge Flashing Work?

Drip edge flashing works by creating a smooth, angled surface that directs water away from the edge of the roof and into the gutter system. It also helps to prevent water from being drawn back up under the roofing material through surface tension, as demonstrated in a recent YouTube video by Ask This Old House.

Installation Tips and Examples

Proper Installation Techniques

To ensure effective water drainage and protection, drip edge flashing should be installed correctly. Here are some key installation tips:

  • Ensure the drip edge extends beyond the edge of the roof by at least 1 to 2 inches.
  • Install the drip edge under the roofing material, with the flange facing outward.
  • Use roofing nails or screws to secure the drip edge in place, spacing them approximately 6 to 8 inches apart.
  • Seal any gaps or joints in the drip edge with roofing cement to prevent water infiltration.

Examples of Effective Installation

In the YouTube video, three different scenarios were demonstrated to illustrate the effectiveness of drip edge flashing:

  1. No Drip Edge: Water was observed seeping under the sheathing due to the lack of drip edge flashing.
  2. Metal Drip Edge: While the metal drip edge helped to some extent, water still reached the fascia board, shortening its lifespan.
  3. Properly Installed Drip Edge: With proper installation and sufficient shingle overhang, water was effectively directed away from the fascia board, preventing water damage.
