What is the Difference Between Drip Edge and Rake Edge? Understanding their Importance in Roofing

Are you a beginner in the roofing industry? Or maybe a DIY enthusiast who’s interested in doing roofing projects on your own? If so, you might have heard of two terms: “drip edge” and “rake edge.” But what are they, and how do they differ?

Basically, a drip edge is a component of roofing that is installed at the edge of a roof to prevent water from flowing behind the fascia and into the soffit. On the other hand, a rake edge is installed at the edge of a gable roof to prevent water from flowing into the building’s interior, which may cause water damage.

Although both drip edge and rake edge serve the same purpose of protecting your roofing system from water penetration, they differ in terms of their location and installation. Understanding the importance of these two roofing components will help you make informed decisions when it comes to maintaining and repairing your roof. So, without further ado, let’s dive into the details!

Roofing materials

Before diving into the differences between drip edge and rake edge, it’s important to understand the different materials commonly used for roofing.

Here are some of the most popular materials:

  • Asphalt shingles: These are the most commonly used roofing material in the United States due to their affordability, durability, and ease of installation.
  • Metal roofing: This type of roofing is becoming increasingly popular for its energy efficiency and longevity. It’s available in a variety of materials, including aluminum, steel, and copper.
  • Tile roofing: This type of roofing is primarily used in warmer climates due to its ability to reflect heat. It can be made of clay, concrete, or slate.
  • Slate roofing: This material is natural and highly durable, making it a great option for those who want a long-lasting roof. However, it’s one of the most expensive roofing materials available.

Now that you have a better understanding of roofing materials, let’s discuss the difference between drip edge and rake edge.

Types of Roof Edges

Roof edges are crucial elements that help keep your home protected from water damage, and they come in a variety of types and shapes to suit different roof styles and designs. The most common types of roof edges include drip edge, rake edge, eave edge, and gable edge. Each of these edges serves a different purpose, and it’s essential to understand their differences to make the right choice for your home.

Drip Edge and Rake Edge

  • Drip Edge
  • A drip edge is a metal flashing that’s installed along the edge of a roof to prevent water from seeping under the shingles and getting into the structure of a home. It’s installed along both the eaves and rakes of a roof and is designed to direct water away from the fascia board and into the gutter system. Drip edges are typically made of galvanized steel, aluminum, or copper and come in different sizes and profiles to match the roof’s pitch and style.

  • Rake Edge
  • A rake edge is also a metal flashing that’s installed along the sloping edge of a roof that runs parallel to the gables. It’s designed to protect the roof decking from water damage, prevent wind uplift, and enhance the roof’s appearance. Rake edges are typically installed under the shingles and extend over the fascia board and the eave trough, creating a finished look. They’re available in different materials, such as aluminum, steel, and copper, and come in various profiles to match the roof’s pitch and style.

Drip edges and rake edges serve different functions, and the main differences between them are their installation and location. While drip edging is installed at the eaves and rake edges at the gables, they both work together to channel water away from the roof’s structure and into the gutter system.

Eave Edge and Gable Edge

Eave edges and gable edges are also crucial elements of a roof that serve different functions from drip edges and rake edges. The eave edge is the horizontal edge of the roof that overhangs the wall, while the gable edge is the vertical edge of the roof that follows the slope of the roof and meets the end wall of the house. These edges are typically finished with fascia boards and soffits, which help create a waterproof barrier between the roof and the structure of the house.

Eave Edge Gable Edge
Protects the fascia, soffit, and gutter system from water damage Protects the end of the roof decking from water and wind damage
Connects the roof to the house without exposing the rafters Enhances the roof’s appearance and protects against wind uplift
Provides a finished look to the eaves of the roof Creates a transition between the roof and the end wall of the house

It’s important to choose the right roof edges for your home since they play a vital role in protecting your roof and house from water damage. Consult with a roofing expert to determine what roof edges are right for your home.

Function of Drip Edge

One of the primary functions of the drip edge is to protect the roof decking and the fascia board from water damage. Water can seep into the edges of roof shingles and flow down to the roof decking, which can lead to rot and other types of water damage over time. The drip edge helps to prevent this by directing the water away from the roof decking and into the gutter system. Specifically, the drip edge overhangs the fascia board and guides the water into the gutters, which helps to minimize the risk of water damage to the fascia board.

Advantages of Using Drip Edge

  • The drip edge helps to prevent water damage to the roof decking and fascia board.
  • It can improve the overall appearance of the roof by covering up the roofing underlayment and decking.
  • The drip edge can help to prevent insect infestations in the roof decking and attic space.

Types of Drip Edge

There are two main types of drip edge: L-shaped and T-shaped. L-shaped drip edges are designed to overhang the edge of the roof and protect against wind-driven rain and water damage. T-shaped drip edges are designed to be installed on the eaves of the roof and create a barrier between the roof decking and shingles, which helps to prevent water damage and improve the overall durability of the roof.

It’s important to choose the right type of drip edge for your specific roofing needs, and to ensure that it’s properly installed to provide maximum protection against water damage and other types of roof-related issues.

Drip Edge Size & Installation

The size and installation of drip edge can affect its effectiveness as well. Typically, drip edges come in 2″ x 2″ standard size, but they can be custom made to fit specific roof configurations. It’s important to choose the right size for your roof to ensure that it adequately protects the roofing system from water damage.

Material Commonly Used Pros Cons
Aluminum Easy installation, lightweight Can corrode over time, not as durable as other materials
Galvanized Steel Durable, long-lasting, thicker than aluminum May rust if not coated properly, heavier than aluminum
Copper Durable, long-lasting, resistant to corrosion More expensive than other materials, requires professional installation

When it comes to installation, drip edge should be installed on all edges of the roof, including the eaves and rakes. It should be installed before the roofing underlayment and shingles, and should be properly secured to the decking with the appropriate fasteners. Improper installation can lead to water damage and other issues, so it’s important to hire a professional roofing contractor to ensure that your drip edge is installed correctly.

Function of Rake Edge

Similar to the function of drip edge, the main purpose of rake edge is to protect the roof as well as the overall structure of the house from water damage. In contrast to the horizontal installation of drip edge, rake edge is installed vertically at the edge of the roof where it meets the gable end of the house. Rake edge also performs several other functions:

  • Prevents water from seeping into the attic and walls: The vertical installation of rake edge helps to prevent water from getting under the roofing material and seeping into the attic or the walls of the house. This is especially important in areas with high winds and heavy rain.
  • Provides support for shingles: Rake edge provides support for the ends of shingles along the edge of the roof, ensuring that they do not bend or sag over time.
  • Creates a finished look: Rake edge helps to create a clean, finished look to the roof by covering the exposed edges of the decking and roofing material.

Types of Rake Edge

There are two types of rake edge: closed and open. Closed rake edge is a metal flashing that is bent to fit the angle of the roof and is installed over the cut ends of the shingles. Open rake edge is installed beneath the shingles and is designed to be visible, creating a decorative element to the roof.

Rake Edge Installation

The installation of rake edge is similar to that of drip edge, with the main difference being that it is installed vertically rather than horizontally. Rake edge should be installed before the roofing material is installed, ensuring a proper fit and maximum protection from water damage. It is important to use a reputable roofing contractor to ensure that rake edge is installed properly to prevent any potential water damage to the roof and house.

Rake Edge Materials

Rake edge can be made from a variety of materials, including aluminum, copper, galvanized steel, and vinyl. The material used will depend on the specific needs of the roof, the climate of the area, and the style of the house.

Material Pros Cons
Aluminum Durable, lightweight, corrosion-resistant, easy to install May not be suitable for heavy snow loads, can dent or scratch easily
Copper Durable, long-lasting, resistant to corrosion, adds a decorative element to the roof Expensive, can develop a patina over time that changes the color
Galvanized Steel Durable, strong, resistant to corrosion Heavier than other materials, may rust over time
Vinyl Lightweight, easy to install, affordable May not be as durable as other materials, can fade or crack over time

Overall, the choice of material for rake edge will depend on a variety of factors, including budget, style, and climate. It is important to choose a material that is durable and provides adequate protection from water damage to ensure the long-term health of the roof and the house.

  • If the rake edge is not attached sufficiently, it can easily become detached during a storm or high winds, resulting in a roof damage or possible injury.

By following the installation tips listed above, you can avoid these potential issues and have a perfect rake edge installation every time.

Importance of Proper Roof Edging

Roof edging is a crucial part of any roofing system. In addition to enhancing the overall aesthetics of the structure, roof edging offers several important functional benefits that help protect the roof and the building as a whole. Of all the different types of roof edging available, drip edge and rake edge are the most commonly used. While both serve similar purposes, they have different applications, and it’s essential to understand their differences to ensure your roof is well protected.

The Difference Between Drip Edge and Rake Edge

  • Drip edge: Positioned along the eaves of the roof, drip edge helps to direct water away from the fascia and into the gutters. Drip edge has a small metal flange that extends out over the roofline to prevent water from seeping underneath the roofing material. The flange also helps to hold the roofing material in place and protect the fascia from moisture damage.
  • Rake edge: Rake edge is located on the gable ends of the roof and works in a similar way to drip edge. Its primary function is to prevent water from penetrating underneath the roofline and damaging the underlying structure. Rake edge also helps to create a finished look to the roof’s edge, and it can be designed to match the style of the roof and the building’s architecture.

The Benefits of Proper Roof Edging

The proper installation of roof edging is essential for the following reasons:

  • Water damage prevention – Without drip edge or rake edge, water can seep underneath the roofing material and damage the underlying structure. The water can also cause mold and mildew growth, which can be hazardous for the building’s occupants and significantly reduce the building’s air quality.
  • Fire prevention – Properly installed roof edging can help prevent embers from igniting debris that may have accumulated under the roof decking.
  • Aesthetics – Properly installed roof edging helps to create a finished and polished look to the roof’s edge that can enhance the overall appearance of the building.
  • Protects the fascia – Drip edge helps to direct water away from the fascia, preventing moisture-related damage that can lead to costly repairs.

The Bottom Line

Proper roof edging is one of the essential components of a roofing system that helps protect the building from water damage, fire, and other hazardous conditions. Drip edge and rake edge are crucial installation features that perform different functions but work together to keep your roofing system well-protected. Consult with a professional roofing contractor to ensure that your roof’s edging is installed correctly to minimize the risk of damage and prolong the life of your roof and the building as a whole.

Remember, prevention is always cheaper than repair in the long run.
