Gutter Apron vs Drip Edge: An In-Depth Comparison

Gutter Apron vs Drip Edge

Last Updated on June 8, 2024 by Kravelv

When it comes to maintaining a home’s roof and preventing water damage, two critical components come into play: the gutter apron and the drip edge. These elements are essential in ensuring that water flows off the roof correctly, protecting both the roof and the structure of the house. Understanding the differences, uses, and benefits of each can help homeowners make informed decisions about their roofing systems. In this article, we will delve deeply into the characteristics, functions, installation processes, and maintenance considerations for both gutter aprons and drip edges.

Key Takeaways:

  • Functionality: Gutter aprons direct water into gutters, while drip edges guide water away from the fascia and roof deck.
  • Design: Gutter aprons have an “L” shape for gutter integration, whereas drip edges have an “L” or “T” shape for comprehensive edge protection.
  • Installation: Gutter aprons are installed under shingles and over gutters; drip edges are installed along roof perimeters.
  • Materials and Maintenance: Both use galvanized steel, aluminum, or copper, requiring regular inspections and maintenance.

What is a Gutter Apron?

A gutter apron is a type of flashing designed to direct water away from the roof edge and into the gutter. It is typically a piece of bent metal installed under the roof shingles and over the edge of the roof, extending into the gutter system.

Purpose and Function

The primary purpose of a gutter apron is to prevent water from seeping under the roof shingles and to ensure that water flows directly into the gutter. This helps to protect the fascia board and the underlying roofing structure from water damage and rot.


Gutter aprons are commonly made from galvanized steel, aluminum, or copper. Each material offers different benefits:

  • Galvanized Steel: Durable and cost-effective but may rust over time.
  • Aluminum: Lightweight, rust-resistant, and easy to install, but can be more expensive than galvanized steel.
  • Copper: Extremely durable and aesthetically pleasing but also the most expensive option.

Installation Process

  1. Preparation: Remove any old flashing and clean the area where the gutter apron will be installed.
  2. Cutting the Apron: Measure the length of the roof edge and cut the gutter apron to size.
  3. Positioning: Lift the shingles slightly and slide the top edge of the apron underneath. Ensure the bottom edge extends over the gutter.
  4. Securing: Nail the apron into place along the roof edge using roofing nails. Ensure the nails are driven through the apron and into the roof decking.
  5. Sealing: Apply a bead of roofing cement along the top edge of the apron where it meets the shingles to prevent water infiltration.

Pros and Cons of Gutter Aprons

Directs water effectively into the gutterLimited to areas where the roof meets the gutter
Protects fascia board and underlying roofing structureCan be less aesthetically pleasing if not installed neatly
Easy to install for most DIY homeownersPotential for water to seep under shingles if not properly installed
Available in durable materials like galvanized steel, aluminum, and copperMay require periodic inspection and maintenance
Helps prevent water damage and rotInstallation requires lifting shingles, which can be tricky for some

What is a Drip Edge?

A drip edge is a metal flashing installed at the edges of a roof to control the flow of water away from the fascia and protect the underlying roofing components. It is usually installed along the eaves and rakes of the roof.

Purpose and Function

The main function of a drip edge is to guide water away from the fascia and into the gutters, preventing water from dripping behind the gutter and causing damage to the roof deck and fascia. It also helps to keep pests and rodents from entering the roof space.


Similar to gutter aprons, drip edges are available in various materials:

  • Galvanized Steel: Strong and affordable but prone to rust.
  • Aluminum: Lightweight, rust-resistant, and easy to cut and install.
  • Copper: Highly durable and visually appealing, with a higher price point.

Installation Process

  1. Preparation: Ensure the roof decking is clean and free of debris.
  2. Measuring and Cutting: Measure the length of the roof edge and cut the drip edge to size, allowing for any necessary overlaps.
  3. Positioning: Place the drip edge along the roof edge, ensuring it extends over the fascia and gutter.
  4. Securing: Nail the drip edge in place using roofing nails. For eaves, the drip edge goes under the underlayment; for rakes, it goes over the underlayment.
  5. Overlapping: When installing multiple pieces, overlap each section by at least 2 inches to ensure a continuous barrier.

Pros and Cons of Drip Edges

Guides water away from the fascia and roof deckInstallation can be more complex, especially on existing roofs
Provides comprehensive protection around the roof perimeterRequires precise installation to be effective
Helps prevent water infiltration and damageMay require different installation methods for eaves and rakes
Enhances roof longevity by preventing moisture-related issuesCan be more expensive, especially in copper
Seals off gaps to prevent pest entryNeeds regular inspection and maintenance to ensure effectiveness

Key Differences Between Gutter Aprons vs Drip Edges

Design and Appearance

  • Gutter Apron: Typically has an “L” shape with a longer vertical leg that fits under the shingles and a shorter horizontal leg that extends into the gutter.
  • Drip Edge: Usually has a more straightforward “L” or “T” shape, with one flange extending over the roof edge and the other over the fascia.

Installation Location

  • Gutter Apron: Installed primarily where the roof meets the gutter.
  • Drip Edge: Installed along the entire perimeter of the roof, including eaves and rakes.

Specific Functions

  • Gutter Apron: Focuses on directing water into the gutter to prevent it from damaging the fascia and roof decking.
  • Drip Edge: Aims to guide water away from the fascia and roof deck, protecting these areas from water damage and infiltration.

Benefits of Using Gutter Aprons and Drip Edges

Protection Against Water Damage

Both components play crucial roles in protecting the roof structure and underlying materials from water damage, which can lead to costly repairs if not addressed.

Pest Prevention

Drip edges, in particular, help to seal off gaps where pests and rodents might enter the roof space, providing an additional layer of protection for the home.

Enhanced Roof Longevity

By ensuring proper water drainage and preventing moisture infiltration, gutter aprons and drip edges contribute to the overall longevity of the roofing system.

Improved Aesthetics

Copper drip edges and gutter aprons can add a touch of elegance and visual appeal to a home, enhancing its overall aesthetic.

Gutter Apron vs Drip Edge Maintenance Considerations

Regular Inspections

Both gutter aprons and drip edges should be inspected regularly, especially after severe weather, to ensure they are securely in place and free from damage.


Keep gutters clean and free from debris to ensure that both gutter aprons and drip edges function effectively. Clogged gutters can lead to water overflow and potential damage.

Repairs and Replacement

Promptly address any signs of damage, such as rust or loose nails, to maintain the integrity of the roof. Replacement of damaged sections should be done as needed to prevent further issues.

Frequently Asked Questions

What is the primary difference between a gutter apron and a drip edge?

Gutter aprons direct water into the gutter, while drip edges guide water away from the fascia and roof deck.

Which is easier to install, a gutter apron or a drip edge?
