Introduction: Lead flashing is an essential component of your roofing system, serving as a protective barrier against water infiltration in vulnerable areas like chimneys, vents, and junctions. Over time, lead flashing may become damaged or deteriorate due to exposure to the elements and wear and tear. When this happens, it’s crucial to know how to replace damaged lead flashing sections to maintain the integrity of your roof. In this blog post, presented by Eastwood Roofing Repairs, we’ll provide a step-by-step guide on effectively replacing damaged lead flashing sections.

Materials and Tools You’ll Need

Before you begin, gather the necessary materials and tools:

  • New lead flashing sheet (of the appropriate thickness and width)
  • Roofing nails or screws
  • Roofing sealant or adhesive
  • Tin snips or a utility knife
  • Measuring tape
  • Pliers
  • Hammer or screwdriver
  • Safety gear (gloves, safety glasses, and a ladder)

Step-by-Step Guide to Replacing Damaged Lead Flashing Sections

  • Safety First: Wear the necessary safety gear and use a secure ladder to access the roof safely.
  • Assess the Damage: Identify the damaged section of lead flashing. It may have cracks, splits, holes, or signs of deterioration.
  • Remove the Damaged Section:
    • Use tin snips or a utility knife to remove the damaged lead flashing.
    • Make clean, straight cuts to ensure a proper fit for the replacement flashing.
  • Measure and Cut the New Flashing:
    • Measure the dimensions of the opening where the damaged section was removed.
    • Cut a new piece of lead flashing that matches these dimensions.
    • Ensure the new flashing is the same thickness as the original.
  • Apply Sealant:
    • Apply a generous amount of roofing sealant or adhesive to the area where the new flashing will be installed.
    • Spread the sealant evenly to create a watertight bond.
  • Install the New Flashing:
    • Press the new lead flashing firmly into the sealant.
    • Ensure it fits snugly in place, covering the opening left by the removed section.
  • Secure with Fasteners:
    • Use roofing nails or screws to secure the new flashing in place.
    • Space them at regular intervals to ensure a secure hold.
  • Seal the Edges:
    • Apply an additional layer of roofing sealant around the edges of the new lead flashing to create a waterproof barrier.
  • Inspect and Test:
    • After completing the replacement, scrutinize the area to ensure a proper seal.
    • Test for leaks by gently spraying water on the repaired section and monitoring for any signs of water infiltration.
  • Clean Up:
    • Remove any excess sealant or debris from the roof and the surrounding area.

Conclusion: Replacing damaged lead flashing sections is a critical aspect of roof maintenance that can help prevent water damage and extend the life of your roofing system. While this guide provides a general overview of the process, it’s essential to follow manufacturer recommendations and consult a roofing professional for more complex repairs.
