15 Types Of Roof Flashing

1. Step Flashing

Step flashing is primarily used against the sides of walls and chimneys.

This roof flashing type is essential for directing water away from the wall and preventing leaks.

This type of roof flashing involves placing a piece of metal under each shingle in a step-like pattern, which guides water efficiently off the roof and down the wall.

By doing this, step flashing ensures that water flows away from critical junctions, maintaining the roof’s structural integrity and preventing potential leaks.

2. Counter Flashing

Counter flashing is used on walls and chimneys, typically sawed into an existing mortar joint.

This type of roof flashing overlaps base flashing to direct water away from the roof structure.

You install counter flashing by embedding it into the mortar joints above the base flashing, creating a watertight seal that prevents water from seeping behind the flashing and causing damage.

Commonly used in conjunction with base flashing on chimneys and walls, counter flashing provides an additional layer of protection, ensuring water is directed away from the structure and into the roofing system.


3. Apron Flashing (Continuous Flashing)

Apron flashing, also known as continuous flashing, is used at the base of a wall or penetration and is shaped like an L. It can extend up to 14 feet in length.

The installation involves fitting the apron flashing at the base of a roof penetration or wall, covering the joint between the roof and the wall to ensure a seamless barrier against water intrusion.

This roof flashing type is particularly effective around dormers and the base of chimneys, directing water away from these areas and preventing leaks, thereby maintaining the overall integrity of the roof system.


4. Base Flashing

Base flashing is required for roof features such as chimneys and is part of a two-piece flashing system.

It is placed at the bottom part of the roof feature to ensure that water is directed downwards.

When water flows down to the base flashing, it meets the counter flashing, which then directs it away from the roof.

This type of flashing is primarily used around chimneys and other vertical roof penetrations, ensuring that rainwater always encounters a flashing surface, effectively directing it away from vulnerable areas.


5. Valley Flashing

Valley flashing is installed where two roof planes meet to form a valley, making it crucial for ensuring proper water flow down these junctions.

The installation of valley flashing often involves an open metal flashing method, where a strip of metal is placed along the valley to guide water down and away from the roof.

This roof flashing type is essential in roof valleys, directing water down the valley and preventing it from penetrating the roof and causing damage. By doing so, valley flashing helps to maintain the overall integrity of the roofing system, especially in areas where two roof planes intersect.


6. Drip Edge Flashing

Drip edge flashing is installed along the edges of the roof to ensure that water is directed away from the fascia and into the gutters.

This thin metal flashing is crucial for preventing water damage to the roof deck and the foundation of the home.

To install drip edge flashing, place a strip of metal along the roof edges overlapping the roof’s edge. This setup ensures that water drips off the edge without soaking into the underlying roofing materials, thereby extending the roof’s lifespan and preventing leaks.


7. Kickout Flashing

Kickout flashing directs water into gutters where step flashing ends, bridging the gap between step flashing and the gutter system.

This type of roof flashing is essential for preventing water from running down walls and causing damage to the foundation.

Kickout flashing is particularly beneficial due to the region’s rainfall patterns.

To install kickout flashing, place a specially shaped piece of metal at the point where the roof meets the gutter to ensure that water flows directly into the gutter. This prevents water from seeping into the walls, which can lead to mold and structural damage.


8. Chimney Flashing

Chimney flashing comprises base flashing and counter flashing to seal the joint between the roof and the chimney.

This roof flashing type is vital for preventing leaks around the chimney area, which is a common site for roof leaks.

In the community of King’s Grant in La Plata, MD, chimney flashing is a standard feature for homes with chimneys.

To install chimney flashing, first place the base flashing at the bottom of the chimney, followed by counter flashing embedded into the chimney’s mortar joints. This setup creates a watertight seal that directs water away from the chimney and roof intersection, protecting both structures from water damage.


9. Headwall Flashing

Headwall flashing is used where vertical walls intersect the roof, guiding water onto the roof system and preventing leaks.

This type of roof flashing is essential in areas where the roof meets a wall, such as at the end of a gable roof.

In the neighborhood of Willowgate, headwall flashing helps to maintain the durability of homes by preventing water intrusion at these critical junctions.

The installation process involves placing the headwall flashing behind the siding, ensuring that water is directed onto the roof and away from the wall. This method helps protect the home’s structure and reduce the risk of water damage.


10. Skylight Flashing

Skylight flashing surrounds skylights to prevent leaks, ensuring that these roof penetrations remain watertight.

This roof flashing type is crucial for homes with skylights, as it prevents water from seeping around the skylight edges.

In the neighborhood of Heritage Green, skylight flashing is commonly installed by roofing contractors to enhance the functionality and longevity of skylights.

The installation of skylight flashing typically involves using prefabricated kits provided by skylight manufacturers or custom-fitting flashing around the skylight. This ensures a tight seal that keeps water out, preserving both the skylight and the surrounding roofing materials.


11. Pipe Vent Flashing

Pipe vent flashing (or vent pipe flashing) fits around pipes that penetrate the roof, ensuring a watertight seal around these openings.

This type of roof flashing is essential for preventing leaks where pipes, such as plumbing vents, pass through the roof.

Pipe vent flashing is a common necessity due to the prevalence of homes with various roof penetrations.

To install pipe vent flashing, fit the flashing or boot snugly around the pipe with shingles installed over the base. This method ensures that water flows around the pipe and is directed off the roof without seeping into the structure.


12. Gutter Apron Flashing

Gutter apron flashing is installed along the gutter line, where the roof meets the gutter.

This roof flashing type features a drip edge that directs water into the gutter, preventing water from damaging the fascia or entering the home.

Gutter apron flashing is a critical component for maintaining effective water management systems.

To install gutter apron flashing, place the metal strip along the edge of the roof so it overlaps the gutter. This setup ensures that water flows smoothly into the gutter, protecting the roof deck and fascia from water damage.


13. Plumbing Vent Boot Flashing

Plumbing vent boot flashing is a cylindrical type of flashing that fits around plumbing vents to ensure a watertight seal.

This type of roof flashing is vital for sealing ventilation pipes and preventing leaks around these roof penetrations.

Plumbing vent boot flashing is commonly used to maintain the integrity of the roofing system.

To install plumbing vent boot flashing, position the boot over the vent pipe with the shingles overlapping the top of the flashing. This installation method creates a secure seal that keeps water out, preserving the roof’s structural integrity.


14. Roof Cricket Flashing

Roof cricket flashing is installed on the high side of a chimney to divert water around the chimney and prevent pooling.

This roof flashing type is essential for protecting both the chimney and the surrounding roof area from water damage.

Roof cricket flashing is particularly useful for homes with larger chimneys.

The installation involves constructing a small, peaked structure (the cricket) behind the chimney, covered with flashing to direct water around the chimney and down the roof. This setup ensures efficient water drainage, reducing the risk of leaks and structural damage.


15. Modified Bitumen Roofing Tape

Modified bitumen roofing tape is a specialized flashing material used in specific building codes, often applied as a tape.

This type of roof flashing provides a watertight and tough seal, making it suitable for various roofing applications.

Modified bitumen roofing tape is frequently used for its durability and ease of application.

To install modified bitumen roofing tape, apply the tape directly to the roof surface or flashing area to create a seamless and waterproof barrier. This method is particularly effective for sealing joints and ensuring long-term protection against water intrusion.

Types Of Roof Flashing Materials

Roof flashing materials play a crucial role in the durability and effectiveness of your roof’s protection. The most commonly used materials include aluminum, copper, steel, and modified bitumen roofing tape. Each material offers unique benefits and has specific applications depending on the requirements of the roof.

Aluminum Flashing

Aluminum flashing is a popular choice due to its lightweight nature and ease of formation.

It’s especially useful in areas like the Clarks Run neighborhood in La Plata, MD, where homeowners appreciate its cost-effectiveness and versatility.

However, aluminum must be coated if it comes into contact with concrete or masonry to prevent corrosion. This makes it a great option for various roof flashing types, but it’s essential to ensure it’s properly coated to maintain its longevity.

Copper Flashing

Copper flashing is highly durable and aesthetically pleasing, making it a premium choice for many homeowners.

In the Willowgate neighborhood, copper roof flashing is valued for its long lifespan and resistance to corrosion.

While it develops a patina over time, many consider this to add character and charm to their homes. Despite being more expensive up front, copper flashing provides excellent value due to its durability and low maintenance requirements.

Galvanized Steel

Galvanized steel is another common material used in roof flashing.

It’s durable, corrosion-resistant, and offers a good balance between cost and longevity, which is ideal for homes in the Agricopia neighborhood of La Plata, MD.

Galvanized steel is typically used in base flashing and other areas where strength and durability are paramount. The installation process of this roof flashing type involves cutting and fitting the steel precisely to ensure a watertight seal, often requiring professional expertise to achieve the best results.

Modified Bitumen Roofing Tape

Modified bitumen roofing tape is a specialized material used for its watertight properties and toughness.

This type of roof flashing tape is particularly beneficial in areas that require a flexible yet durable seal, such as in the Heritage Green neighborhood.

The tape is applied directly to the roof surface, creating a seamless barrier against water intrusion. It’s an excellent choice for repairs and new installations where traditional metal flashing might not be suitable.
