Is Your Roof Flashing A Problem? What To Know

Roof flashing is a crucial component of a roofing system that helps prevent water intrusion and protects vulnerable areas of the roof, such as joints, valleys, chimneys, skylights, and vent pipes. However, several common issues can arise with roof flashing. Here are a few examples and how your roofer can address them:

  1. Leaks: Improper installation, damage, or deterioration of flashing can lead to water leaks. A roofer can inspect the flashing to identify any gaps, cracks, or loose sections. They may repair or replace damaged flashing, ensuring proper overlap and secure attachment to prevent water penetration.
  2. Rust or Corrosion: Metal flashing is susceptible to rust or corrosion over time, especially in areas with high moisture or salt exposure. A roofer can examine the flashing for signs of rust or corrosion and replace any affected sections. Applying a rust-inhibiting coating can also help extend the life of the flashing.
  3. Separation or Lifting: Flashing that has become separated or lifted from the roof surface can compromise its effectiveness. A roofer can reattach or secure the flashing properly to ensure a tight seal and prevent water intrusion. They may use roofing cement, sealants, or fasteners to secure the flashing in place.
  4. Improper Flashing Installation: Incorrect installation techniques can result in flashing problems. This includes improper sizing, inadequate overlap, or failure to use appropriate sealants. A roofer can rectify installation issues by reinstalling the flashing correctly, ensuring it is properly integrated into the roofing system.
  5. Age and Wear: Over time, flashing materials may deteriorate due to exposure to the elements, UV rays, or temperature fluctuations. A roofer can assess the condition of the flashing and replace it if it has reached the end of its lifespan or shows signs of significant wear and tear.
  6. Inadequate Flashing Design: Poorly designed flashing can lead to water accumulation and subsequent leaks. A roofer can evaluate the flashing design, identifying any design flaws or deficiencies. They can recommend and implement appropriate modifications or improvements to enhance the flashing system's performance.

Regular maintenance and inspections by a qualified roofer can help identify flashing issues early on and prevent more significant problems. It's essential to hire experienced professionals who understand proper flashing installation techniques, use high-quality materials, and adhere to industry best practices. By addressing these common issues, roofers can ensure the integrity of the flashing and contribute to a watertight and durable roofing system.
