Understanding Roofing Flashing:

A Comprehensive Guide by Hart Roofing & Construction

Asphalt shingles are one of the most widely used roofing materials in the United States. 

They are composed of a fiberglass or organic base mat coated with asphalt and embedded with ceramic granules to enhance durability and UV protection. 

These shingles are available in a wide range of styles and colors, making them a versatile choice for various architectural designs.

Flashing, a term often used in roofing and construction, refers to the thin metal or other impervious material that is strategically placed in various locations on a roof to prevent water from infiltrating he building structure. 

Flashing acts as a barrier, directing water away from critical junctures where roofing materials meet other surfaces, such as walls, chimneys, and valleys.

Chimney flashing is a critical element of any roofing system. 

It involves the installation of flashing around the base of the chimney to create a watertight seal between the chimney and the roof. 

This prevents rainwater from seeping into the roof deck and causing potential damage.

What is Flashing?

Flashing, in the context of roofing and construction, refers to the material or component used to create a waterproof barrier at vulnerable points on a building’s structure. Its primary purpose is to prevent water infiltration and leakage through joints, intersections, and transitions where different building materials and surfaces meet. Flashing is particularly important in areas where the natural flow of water could potentially lead to water damage, rot, or deterioration of the building materials.

Flashing is typically made from durable materials such as metal (e.g., aluminum, copper, galvanized steel), rubber, or specialized waterproofing membranes. It is strategically installed to redirect water away from critical junctures, ensuring that water does not seep into areas where it could cause structural damage, leaks, or moisture-related issues.

Types of Roof Flashing

There are several types of flashing, each designed for specific areas and purposes:

  • Step Flashing: Step flashing is used along the sides of a chimney or any vertical wall that intersects with the roof. It is composed of individual pieces that are layered with roofing material, creating a stepped appearance.
  • Valley Flashing: Valley flashing is placed in the valleys created by the intersection of two roof slopes. It channels water away from this vulnerable area to prevent leaks.
  • Drip Edge Flashing: Drip edge flashing is installed along the edges of the roof to direct water away from the fascia and into the gutters, preventing water damage and wood rot.
  • Apron Flashing: Apron flashing is used to prevent water from running down a vertical surface, such as a wall, and getting trapped behind the roofing materials.
  • Counter Flashing: It requires precision and skill to install counter flashing. Counter flashing is used in conjunction with a base flashing to create a waterproof barrier around chimneys, parapet walls, and other vertical projections.
  • Wall Flashing: Wall flashing protects the intersection of a roof and a vertical wall, ensuring water does not infiltrate this vulnerable joint.

Common areas where Flashing is used include:

Flashing is applied at the point where the roof meets a vertical wall. This prevents water from running down the wall and infiltrating the building.

Flashing is used around chimneys, plumbing vent pipes, and other protrusions on the roof to seal the area and prevent water from entering.

Flashing is used around dormer windows and structures that project from the roof to keep these intersections watertight.

Flashing is installed around skylights to prevent water from seeping into the roof around these openings.

Drip edge flashing is placed along the edge of the roof to guide water into gutters and prevent it from getting under the roofing materials.

Flashing is applied along the sides of vertical walls and parapets to prevent water from infiltrating behind the wall surface.

Properly installed flashing is an integral part of a roofing system, ensuring its longevity and protecting the overall structural integrity of a building. When flashings are poorly installed or neglected, they can lead to leaks, water damage, and costly repairs. Therefore, understanding the different types of flashing and their appropriate installation is crucial for maintaining a watertight and secure building envelope.
