10 Best Roof Flashing Types

Selecting the right type of roof flashing is essential for preventing water infiltration and ensuring the longevity of your roofing system. In the following section, we will explore the 10 best roof flashing types, highlighting their unique features and benefits to help you make an informed decision for your home.

1. Step Flashing

Step flashing is a versatile and highly effective flashing type often used where the roof intersects with a vertical wall. Its name derives from the way it is installed in steps along the shingles.

• Superior Water Resistance: The overlapping design ensures that water is effectively directed away from the wall and roof joint.
• Durability: Made from robust materials like galvanized steel or aluminum, step flashing offers long-lasting protection.
• Aesthetic Integration: Can be painted to match the roof or wall, ensuring it blends seamlessly with the overall design.

2. Valley Flashing

Valley flashing is used in roof valleys, where two roof planes meet. This type of flashing is essential in directing water flow and preventing accumulation in these areas.

• Efficient Water Channeling: Designed to handle large volumes of water, minimizing the risk of leaks in valleys.
• Strength and Longevity: Typically made from materials like copper or aluminum, which are resistant to corrosion and wear.
• Ease of Installation: Prefabricated valley flashings are available, simplifying the installation process.

3. Drip Edge Flashing

Drip edge flashing is installed along the edges of the roof to direct water away from the soffits and fascia and into the gutters, preventing water damage to the roof deck and fascia board.

• Enhanced Water Protection: Prevents water from seeping under the shingles and causing damage to the roof structure.
• Structural Integrity: Supports the shingles at the edges, preventing sagging and potential damage.
• Improved Gutter Performance: Ensures that water flows directly into the gutters, reducing the risk of overflow and ice dams.

4. Counter Flashing

Counter flashing is installed on walls or chimneys above the base flashing to provide an additional layer of protection. It works in conjunction with base flashing to create a waterproof barrier.

• Increased Waterproofing: Provides an extra layer of defense against water infiltration.
• Versatility: Can be used in various applications, including chimneys, skylights, and wall joints.
• Aesthetic Appeal: Can be customized to blend with the surrounding materials, maintaining the visual appeal of the structure.

5. Chimney Flashing

Chimney flashing is specifically designed for areas where the chimney meets the roof. It consists of several components, including step flashing and counter flashing, to ensure comprehensive protection.

• Complete Protection: Addresses all potential points of water entry around the chimney.
• Durability: Made from materials like lead, copper, or stainless steel, providing long-lasting protection.
• Custom Fit: Can be tailored to fit the specific dimensions and shape of the chimney, ensuring a tight seal.

6. Skylight Flashing

Skylight flashing is used to seal the areas around skylights, preventing water from leaking into the roof structure. It often includes a combination of head flashing, sill flashing, and step flashing.

• Leak Prevention: Designed to create a watertight seal around the skylight, preventing leaks and water damage.
• Compatibility: Available in various sizes and shapes to match different types of skylights.
• Energy Efficiency: Helps maintain the insulation integrity of the roof, contributing to overall energy efficiency.

7. Vent Pipe Flashing

Vent pipe flashing is used to seal the areas around roof penetrations for vent pipes, ensuring that water does not leak into the roof structure.

• Effective Sealing: Features a flexible collar that fits snugly around the pipe, providing a watertight seal.
• Weather Resistance: Made from durable materials like rubber, silicone, or metal, which can withstand harsh weather conditions.
• Easy Installation: Designed for straightforward installation, making it a popular choice for both DIY and professional roofers.

8. Continuous Flashing

Continuous flashing, also known as apron flashing, is used where a vertical surface meets a sloped roof. It provides a seamless barrier against water infiltration.

• Uninterrupted Protection: The continuous design ensures there are no gaps where water can penetrate.
• Ease of Installation: Simple to install, reducing labor time and costs.
• Adaptability: Can be used in various applications, including along walls, chimneys, and skylights.

9. Base Flashing

Base flashing is used at the base of walls, chimneys, and other vertical surfaces. It works in conjunction with counter flashing to create a waterproof seal.

• Reliable Waterproofing: Effectively directs water away from critical areas, preventing leaks.
• Durability: Constructed from sturdy materials like aluminum, copper, or galvanized steel, ensuring long-term protection.
• Compatibility: Works well with other flashing types to provide comprehensive coverage.

10. Kick out Flashing

Kick out flashing is installed where a roof edge meets a vertical wall, directing water away from the wall and into the gutter. It is particularly useful in preventing water damage to the building’s siding and foundation.

• Enhanced Water Management: Effectively channels water away from the wall, preventing water damage.
• Prevents Mold and Mildew: Reduces the risk of moisture buildup in the wall cavity, preventing mold and mildew growth.
• Durability: Made from materials that resist corrosion and wear, ensuring long-lasting performance.
