Roof flashing is very important in protecting your home from water damage. Positioned around roof penetrations like chimneys, skylights, vents, and along roof valleys, flashing directs water away from vulnerable areas. When flashing is damaged, improperly installed, or worn out, it can lead to serious leaks that compromise your roof and home. Xpert Xterior would like to discuss how to identify flashing problems and why it’s important to fix them before they turn into leaks.
What is Roof Flashing & Why Does it Matter?
Roof flashing is typically made from metal such as aluminum, copper, or galvanized steel and serves as a barrier to water penetration. Its main purposes are directing rainwater and melting snow away from roof penetrations. The flashing seals the gaps between roofing materials and structures and preventing leaks and water damage to your home’s interior. Even small cracks, gaps, or rust spots in flashing can allow water to seep into your home, leading to structural damage, mold, and costly repairs.
Signs of Flashing Problems
Here are common signs that your roof flashing may need attention.
• Rust or Corrosion: Metal flashing can rust over time, creating holes and weak spots.
• Cracks or Splits: Flashing around chimneys, vents, or skylights may crack due to temperature changes or roof movement.
• Loose or Missing Sections: Fasteners can fail, or flashing may pull away from the roof, leaving gaps.
• Water Stains or Leaks: Water stains in the attic, walls, or ceilings often indicate flashing issues.
• Peeling or Damaged Sealant: Sealants around flashing may crack or deteriorate, reducing effectiveness.
Detecting these issues early is key to preventing leaks and extensive roof damage.
Common Causes of Flashing Problems
Flashing issues can result from several factors: Is aging materials, over time, metal corrodes and sealants dry out. Improper flashing placement or fastening can create weak points. The roofing material will experience expansion, contraction, or structural shifts which can cause flashing to loosen. Lastly, heavy wind, hail, or snow can bend or dislodge flashing. Understanding the cause helps determine the best repair approach and prevents future problems.
Fixing Flashing Problems
Repairing flashing depends on the severity of the damage:
Minor Repairs: Resealing small cracks or gaps with high-quality roofing sealant around the flashing. You will need to refasten loose flashing using corrosion-resistant nails or screws and replace worn caulk around penetrations.
Major Repairs or Replacement: Replacing corroded or severely damaged flashing is sometime needed. Installing new flashing around roof penetrations for proper water diversion. Replacing flashing along roof valleys to prevent pooling water
Roof flashing repairs can be tricky, especially on steep or high roofs. Hiring a professional ensures the repair is safe, long-lasting, and properly sealed.
