Shed roof drip edge is a crucial component that protects your shed from water damage and wear. It's a simple, yet effective solution that can save you money in the long run.
A drip edge is typically made of metal or vinyl and is installed along the edges of your shed roof. This helps to direct water away from the roof and walls, preventing it from seeping in and causing damage.
The ideal length for a drip edge is usually 1-2 inches longer than the width of your shed roof. This ensures that it overlaps the roof's edge and provides maximum protection.
A well-installed drip edge can last for many years, but it's not maintenance-free. Regular inspections can help identify any damage or wear, allowing you to make repairs before they become major issues.
What Is a Shed Roof Drip Edge?
A shed roof drip edge is a crucial component of a shed roof's overall design. It's a trim piece installed along the edges of the roof to help water run off and prevent damage.
Typically, a shed roof drip edge is made of metal or vinyl and comes in various styles and materials. In some cases, it may be made from aluminum or steel, which are durable and resistant to corrosion.
The primary function of a shed roof drip edge is to direct water away from the shed's walls and foundation. By doing so, it helps prevent water from seeping into the shed and causing damage.
What Is?
A drip edge is a metal flashing piece installed at the outer edge of your roof, typically bent into an "L"-shape, which creates a small overhang that funnels water out and slightly away from the horizontal surfaces below.
The typical roof drip edge overhang is two to five inches, and residential roofing companies can determine the appropriate size and style drip edge for your roof style and local weather conditions.
Drip edge flashing is made of materials like aluminum, steel, copper, or other non-staining and corrosion-resistant materials, making it waterproof and long-lasting.

A drip edge is relatively inexpensive but highly impactful in preventing water and wind damage, which is why it's an essential part of your roof system.
Here are some key terms to understand when it comes to roof structure and drip edges:
- Eaves: The horizontal edges of the roof that hang out at least a few inches past the wall.
- Gable end: The outward-facing wall of a house where the two slopes of a pitched roof meet to form a ridge.
- Rake edge: The sloped edges on the gable ends of the roof, which typically don't have gutters.
- Fascia: The outward-facing, horizontal board that runs along the edge of the roof.
- Soffit: The board connected perpendicular to the fascia on the underside of the eaves, which ventilates your attic and roof system.
The drip edge is typically recognized as the horizontal flashing at the end of the eaves, but it should also be connected to and installed along the rake edges.
How a Works
A shed roof drip edge is a crucial component that helps direct water away from the fascia and prevents damage to your shed. It's essentially a horizontal flashing that sticks out past the fascia to allow water to drip into the gutter or directly off of the house.
The purpose of a drip edge is twofold: it directs water away from the fascia and protects the roof from wind-driven rain. Without a drip edge, water can stick to the shingles and potentially work its way under the shingles to cause a leak.
Water can also cling to the fascia, causing rot or a leak into the home. In severe conditions, wind can push water upwards before gravity pulls it down, making it essential for the drip edge to hang significantly off the edge of the roof.
A drip edge is typically installed along the eaves and rake edges of the roof. The eaves are the horizontal edges of the roof that hang out at least a few inches past the wall, while the rake edges are the sloped edges on the gable ends of the roof.
Here are the key components of a roof structure, relevant to understanding how a drip edge works:
- Eaves: The horizontal edges of the roof that hang out at least a few inches past the wall.
- Gable end: The outward-facing wall of a house where the two slopes of a pitched roof meet to form a ridge.
- Rake edge: The sloped edges on the gable ends of the roof.
- Fascia: The outward-facing, horizontal board that runs along the edge of the roof.
- Soffit: The underside of the eaves, connected perpendicular to the fascia, which ventilates the attic and roof system.
By understanding these components and how a drip edge works, you can ensure your shed roof is properly protected from water damage and wear.
Types of Shed Roof Drip Edge
Shed roof drip edge is a crucial component in keeping your shed dry and protected from the elements.
Drip edges are sold in lengths of 10.5 feet, but you may also find them in 8-foot lengths or smaller. The length of the overhang itself commonly ranges from 2 to 5 inches.
There are three main types of drip edge, each with its own unique characteristics. Type C is the classic "L"-shaped drip edge, which is bent to a 90-degree angle and has a lower flange at the bottom.
Type D, also known as "hemmed edge" or "T-shaped" drip edge, is bent to direct water further away from the fascia. It's great for directing water directly into the gutter or away from the foundation.
Type F, also known as "gutter apron" flashing, is an extended drip edge with a longer leading edge. This makes it useful when installing new drip edges over existing shingles or on rake edges.
Here are the main types of shed roof drip edge, summarized in a table:
Benefits and Importance
A drip edge is a crucial component of a shed roof, and its benefits are numerous. It helps to keep your shed watertight by directing water away from the fascia board, roof, and foundation.
Proper placement of drip edge is critical to ensure it works effectively. If installed too close to the shed or in the wrong spots, it can cause drips down the fascia board and allow water to enter the eaves of the shed.
A drip edge can help to protect your gutters by creating a continuous flow of water and keeping out dirt and debris. This makes your gutters more effective and efficient, reducing the need for frequent cleaning.
The drip edge also seals off gaps that would allow insects or small animals to access your roof deck and home. This is especially important in areas where pests are a common problem.
Here are some key benefits of having a drip edge on your shed roof:
- Keeps the fascia board, roof, and foundation dry
- Protects gutters from dirt and debris
- Seals off gaps to prevent pest access
In addition to these benefits, a drip edge can also help to protect your shed from ice dams. By forcing icicles to form on the drip edge rather than the roof fascia or shingles, you can prevent damage to your roof's integrity.
Installation and Materials
Installing drip edge on your shed roof is a straightforward process, but it does require some attention to detail. Start by fastening the top part of the drip edge directly into the roof, and then fit the lower flange snugly against the fascia without a fastener.
The type of material you choose for your drip edge is crucial. Aluminum is a popular choice, as it's affordable and sturdy enough to last for many years without corroding.
Galvanized steel is a stronger option, but it's also more expensive. To ensure it holds up against strong winds and prevents rust, make sure it's at least 24-gauge galvanized steel.
Copper is a more premium option that provides excellent curb appeal, but it's also the most expensive. A 20-ounce copper drip edge is very sturdy and can sometimes last for 100 years.
Here are some key things to keep in mind when choosing your drip edge material:
- Aluminum drip edge flashing is the most affordable material and is sturdy enough to hold up for many years.
- Galvanized steel drip edge flashing is stronger than aluminum, but it's also more expensive.
- Copper drip edge flashing is the most expensive option, but a 20-ounce copper drip edge is very sturdy and can last for 100 years.
To ensure proper water runoff, make sure the drip edges at the eaves and the rake edges of the roof are connected. This is usually done by cutting and bending a piece of the metal to fit snugly around the corner of the roof.
Design and Profile Options
When choosing a drip edge for your shed roof, you'll want to consider the profile type. There are three basic profiles of drip edge flashing: Type C, Type D, and Type F.
Type C, also known as the "L" style, is a classic choice that's been used for a long time. It's bent to a 90-degree angle and has a lower flange at the bottom.
Type D, also known as drip metal or "T style", is shaped like a "T" and keeps the water further away from the fascia. The Asphalt Roofing Manufacturers Association (ARMA) recommends this profile over Type C.
Type F, or the "F style" or "gutter apron", has a longer leading edge, making it ideal for installing new drip edges over existing shingles or on rake edges.
Drip edges are usually sold in 10.5-foot lengths, but you may also find them in 8-foot lengths or smaller. The length of the overhang itself typically ranges from 2 to 5 inches.

Redirecting Wind-Driven Rain
Redirecting wind-driven rain can be a major issue for any roof, especially those with shed roofs. This is because wind can force rain to hit your roof at an angle, allowing water to seep under the shingles.
Your shingles are designed to protect your roof deck from vertical rain, but they can't withstand the force of wind-driven rain. Imagine an umbrella that keeps you dry in a vertical rain, but a heavy wind makes you wet in areas previously protected.
The drip edge acts as a seal for the edge of your roof, closing off the area that would otherwise be open to water pushed by the wind. This is crucial in preventing leaks and water damage.
Wind-driven rain can be a major problem for shed roofs, but with the right protection, you can keep your home dry and safe. A well-installed drip edge can make all the difference.
