What is Flashing and Why You Need It

Flashing is the material used in roofing systems to prevent water penetration and leaks in areas where the roof meets other building elements, such as walls, chimneys, skylights or vents. Roof flashing is a crucial element in roofing systems, as it helps maintain the roof’s integrity, prevents water damage, and contributes to the overall longevity of the structure.

Some of the primary functions of flashing include:

  • Water Protection: Its primary role is to prevent water from entering the interior of your home. It is installed in vulnerable areas, acting as a barrier to direct water away from those areas.
  • Sealing Joints: Roof flashing seals the joints and transitions between different roofing materials or surfaces. It creates a watertight seal, preventing water from infiltrating through gaps or seams.
  • Preventing Leaks: Without proper flashing, water can seep into your home, leading to structural damage, mold growth, and other issues.
  • Longevity: Roof flashing can extend the lifespan of a roof by preventing premature deterioration caused by water intrusion. It also helps preserve the integrity of roofing materials.
  • Aesthetic Appeal: Roof flashing can improve the appearance of a roof by providing a clean and finished look to the areas where different materials or surfaces meet.

Roof flashing plays a critical role in maintain the integrity of a building’s roof and preventing water damage, making it an essential component of a well-constructed roof.
