Kickout Flashing vs. Drip Edge Flashing

January 27, 2025

A roof needs a strong defense against rainwater to ensure longevity, and flashing can provide that protection. These strong, waterproof materials redirect water from joints and seams on a roof, keeping the interior dry and protecting the building in the long run. If you are a roofer or you supply flashing materials, you’ll likely run into two common types — kickout and drip edge flashing. Each plays a unique role in safeguarding a building and improving a roofing system’s overall performance.

Understanding their differences can ensure you get the right material for the job, protect client roofs and stay code-compliant.

What Is Drip Edge Flashing?

Drip edge flashing is made from metal and directs water away from the roof and into the rain gutter. It is installed at the roof’s edge to guide water away from the fascia board and keep it from seeping under the shingles and into the roof deck or walls. Without it, rainwater can leak into the fascia and cause rot, decay and mold growth, all of which can weaken the roof’s structural integrity over time.

Drip edge flashing can also prevent ice dams from forming along the roof edges, a common issue in colder climates. The roofing material serves as a barrier from water seepage into the roof deck.

Drip Edge Types

Two types of drip edge flashing are commonly used in roofing projects — L-shaped and T-shaped. L-shaped is more common, extending horizontally from the roof’s edge and vertically against the fascia board to create a protective barrier. A T-shaped drip edge is used in areas where the roof meets a wall, providing another layer of protection to keep water away from the joint.

Drip edge flashing is made of metal to withstand the elements. The most common materials include:

  • Aluminum, the standard drip edge
  • Galvanized steel, a corrosion-resistant solution
  • Copper, an alternative solution that turns green with oxidation

What Is Kickout Flashing?

Kickout flashing is a specialized waterproofing method that diverts water from the walls into the gutter. When installed at the intersection of the roof and wall, kickout flashing works with the gutters to protect the walls from excess water exposure. Over time, water can erode the siding on a commercial property or home. As the problem persists, it can lead to mold and structural damage.

Kickout flashing’s unique sloped design can protect against moisture intrusion, rot, pooling and foundation issues. When installed properly, it blocks water from hitting the wall adjacent to the roof. Instead, rainwater and melting snow redirect from the roof and into the gutter system without touching the wall. For these reasons, kickout products are especially beneficial in areas with a lot of water runoff, like steep slope valley roofs.

Kickout flashing protects a building’s exterior from water damage, extending the material’s life span. It saves property owners from costly repairs and ensures buildings are up to code.

Kickout Flashing Types

Kickout flashing is typically made from metal, like heavy-duty aluminum. The metal is resistant to UV rays and mold, so it can withstand sun, rain and snow exposure on the roof without breaking down.

You can find both coated and uncoated kickout flashing. While both provide adequate long-term protection for a building, coated kickout flashing has additional advantages. The heavy-duty powder coating provides an extra layer of protection and can match the color of a building for visual appeal. However, some companies prefer the uncoated version due to its affordability.

Both options can last many years, safeguarding a building’s wall from water damage. So, the choice between coated or uncoated kickout flashing depends on your client’s personal preferences and budget considerations.

The Difference Between Kickout and Drip Edge Flashing

Kickout flashing and drip edge flashing are both critical components of roofing systems. However, they serve different purposes and are installed in distinct locations.

Kickout flashing is installed at the intersection of a sloped roof and a vertical wall. Its primary function is to direct water away from the wall and into the gutter system, preventing damage like rot or mold. It’s usually shaped like a three-sided box that extends outward, guiding water in the gutter.

In contrast, drip edge flashing is installed along the roof’s edges, specifically at the eaves and rakes. Its primary role is to prevent water from running underneath the roofing material and to direct it away from the fascia and underlying structures. It typically extends beyond the roof edge so water can drip off without affecting the roofing or siding.

So, while both types of flashing are essential to roofing systems, kickout flashing redirects water at wall intersections, while drip edge flashing manages water at the roof’s edges.

Choosing the Right Flashing

When deciding between kickout and drip edge flashing, you’ll need to consider the following factors:

  • Roof design: Kickout flashing is ideal for installations where a sloped roof meets a vertical wall. If the roof design includes such intersections, this type of flashing is vital to ensure proper drainage and protect the structure’s integrity. Conversely, drip edge flashing is critical for the roof’s eaves and rakes.
  • Project: If you’re trying to direct water from the wall and the gutter system or to prevent water damage and mold growth, kickout flashing will do the trick. If the project aims to direct water off the roof and prevent moisture from getting into the underlying structure, drip edge flashing is the best choice. Drip edge flashing is also a good option to prevent ice dams and water pooling.

Ultimately, the choice between kickout and drip edge flashing depends on the roof’s design and the potential for water intrusion. Both flashing types might be necessary. Together, they can provide comprehensive protection from the elements and ensure the longevity of the client’s roof.
