Its purpose

What is Roof Flashing?

Roof flashing is a thin, weather-resistant material typically made from aluminum, copper, or galvanized steel. Its primary purpose is to prevent water from seeping into vulnerable areas of your roof, such as joints, edges, and transitions where different materials meet. Without proper flashing, water can infiltrate these areas, leading to leaks, mold growth, and structural damage.

What Does Roof Flashing Do?

Roof flashing serves as a barrier against water penetration, guiding rainwater away from critical areas and preventing it from seeping into your home. It is strategically installed in areas such as:

  • Valleys: Where two roof slopes meet, creating a low point where water tends to accumulate.
  • Chimneys: Around the base and along the edges to seal gaps between the chimney and roof.
  • Vent Pipes: Where plumbing or exhaust vents protrude through the roof.
  • Skylights: Along the edges to prevent water from seeping underneath.
  • Roof Edges: Along the eaves and rakes to direct water into gutters.

What Does Damaged Roof Flashing Look Like?

Identifying damaged roof flashing is crucial for preventing water intrusion and subsequent damage to your home. Signs of damaged flashing include:

  • Rust or Corrosion: Especially common with older metal flashing.
  • Cracks or Gaps: Visible openings where flashing should be sealed tightly against surfaces.
  • Lifting or Warping: Flashing that has pulled away from its intended position.
  • Missing Sections: Parts of the flashing may have fallen off or become dislodged.
  • Water Stains on Ceilings or Walls: Indicating that water is infiltrating through compromised flashing.

The Dangers of Leaving Roof Flashing Damaged:

Ignoring damaged roof flashing can lead to a host of problems, including:

  • Water Damage: Leaking water can cause rotting wood, deteriorating insulation, and mold growth.
  • Structural Damage: Prolonged water exposure can weaken roof decking, rafters, and other structural elements.
  • Health Hazards: Mold growth resulting from water intrusion can pose health risks to occupants.
  • Reduced Energy Efficiency: Moisture infiltration can compromise insulation, leading to higher energy bills.
  • Decreased Property Value: Untreated water damage can detract from the value and curb appeal of your home.
