What is Flashing?
Definition of flashing
Flashing refers to the protective material used in roofing systems to prevent water from entering the building at vulnerable areas, such as joints, valleys, protrusions, and intersecting planes. It is typically made of metal or other durable materials and is installed to redirect water away from critical areas on the roof.
Importance of flashing in roofing
Flashing plays a crucial role in maintaining the integrity of a roofing system. By preventing water intrusion, flashing helps protect the underlying structure from damage, including leaks, rot, and mold. Properly installed flashing is essential for ensuring the long-term durability and functionality of the roof, as well as maintaining the overall health of the building.
Types of Flashing
Step flashing
Step flashing is used along the intersection of a roof slope and a wall. It consists of individual metal pieces that are installed overlapping each other, similar to steps, hence the name. Step flashing effectively diverts water away from the joint, preventing leaks and potential water damage to the wall and roof.
Chimney flashing
Chimney flashing is specifically designed to protect the area where the chimney meets the roof. It is typically made of metal, such as galvanized steel or copper, and is installed in layers to create a watertight seal. Chimney flashing prevents water from seeping into the space between the chimney and the roof, reducing the risk of leaks and structural damage.
Valley flashing
Valley flashing is used in areas where two roof planes come together, creating a valley. It is installed along the joint to form a water-resistant barrier and direct water away from the valley. Valley flashing is often made of metal or specialized valley flashing materials, such as modified bitumen, to ensure optimal protection against water infiltration.
Vent pipe flashing
Vent pipe flashing is installed around vent pipes on the roof to create a weatherproof seal. It typically consists of a base that fits around the vent pipe and a metal or rubber boot that extends up the pipe. Vent pipe flashing prevents water from entering around the vent pipe and causing leaks or damage to the roof.
Skylight flashing
Skylight flashing is used to seal the area around skylights, ensuring a watertight barrier. It is usually made of metal and is installed to prevent water from seeping into the roof around the skylight. Properly installed skylight flashing helps prevent leaks and protects the interior of the building from water damage.
Materials Used for Flashing
Galvanized steel flashing
Galvanized steel flashing is one of the most common materials used for flashing. It is durable, affordable, and resistant to corrosion. Galvanized steel flashing provides excellent protection against water infiltration and is often used in various types of flashing, including step flashing, chimney flashing, and valley flashing.
Aluminum flashing
Aluminum flashing is lightweight, corrosion-resistant, and easy to work with. It is commonly used in flashing applications where weight is a concern, such as around windows and skylights. Aluminum flashing can be painted to match the roof or building aesthetic, making it a versatile choice for flashing installations.
Copper flashing
Copper flashing is highly durable, offers excellent corrosion resistance, and has an attractive appearance that develops a natural patina over time. It is often used in high-end roofing projects where aesthetics and longevity are important. Copper flashing provides superior protection against water intrusion and can last for several decades.
Lead flashing
Lead flashing is a traditional material used in flashing installations. It is known for its malleability, making it easy to shape and mold around complex areas. Lead flashing offers exceptional resistance to weathering and is commonly used in chimneys, valleys, and other critical flashing areas.
PVC flashing
PVC flashing is a synthetic material that offers excellent durability and resistance to weathering. It is often used in low-slope roofing applications and is compatible with various roofing materials. PVC flashing is lightweight, easy to install, and provides reliable protection against water infiltration.
Flashing Installation Process
Assessing the roof for flashing needs
Before installing flashing, it is essential to assess the roof to determine the areas that require flashing. Roofing professionals will inspect the critical points, such as chimneys, skylights, vent pipes, and valleys, to identify potential water intrusion points and plan the flashing installation accordingly.
Preparing the area for flashing installation
Once the areas requiring flashing have been identified, the roof should be prepared for installation. This includes cleaning the surface, removing any debris or obstructions, and ensuring proper adhesion for the flashing material.
Measuring and cutting the flashing material
The flashing material will be measured and cut to the appropriate length and shape for each specific area. Precise measurements are crucial to ensure a proper fit and a watertight seal.
Applying roofing sealant
Before installing the flashing material, roofing sealant may be applied to the surface to create an additional layer of protection against water infiltration. The sealant helps create a tight bond between the roof and the flashing, reducing the risk of leaks.
Positioning and securing the flashing
The flashing is then positioned in the designated area and secured using appropriate fasteners, such as nails or screws. Care must be taken to ensure the flashing is properly aligned and securely attached to the roof to prevent water from penetrating the joints.
Proper sealing and waterproofing
To ensure optimal waterproofing, roofing sealant is applied to all seams, joints, and intersections of the flashing. This further enhances the water resistance of the flashing installation and helps prevent leaks.
Inspecting the flashing installation
Once the flashing installation is complete, a thorough inspection should be conducted to ensure that all areas are properly sealed and no gaps or defects exist. This inspection is important to identify and rectify any issues before they result in leaks or other forms of water damage.
Common Flashing Problems
Leaking flashing
One of the most common problems with flashing is leaking. Leaks can occur due to a variety of reasons, such as improper installation, corrosion, or damage to the flashing material. Leaking flashing can lead to significant water damage if not addressed promptly.
Loose or damaged flashing
Flashing that becomes loose or damaged can compromise its effectiveness in preventing water intrusion. This can happen due to weather conditions, poor installation techniques, or natural wear and tear over time. It is crucial to address loose or damaged flashing to maintain the integrity of the roofing system.
Improperly installed flashing
Flashing that is not installed correctly can lead to various issues, including leaks and water damage. Improper installation techniques or lack of attention to detail during the installation process can result in ineffective flashing that fails to provide the necessary waterproofing.
Flashing corrosion
Certain metals used for flashing, such as galvanized steel or copper, can be susceptible to corrosion over time, especially in regions with harsh weather conditions. Corrosion weakens the flashing material and can lead to leaks and structural damage if not addressed.
Flashing separation
Flashing can separate from the roof due to factors such as strong winds, aging, or poor installation. When flashing becomes separated, water can penetrate the gaps and cause leaks. Regular inspection and maintenance are essential to identify and address any flashing separation issues.
Signs of Flashing Issues
Water stains on ceilings or walls
