Chimney Flashing Repair or Replacement

in Chimney Flashing Repair Chimney Flashing Replacement

Chimney flashing is a critical component that helps prevent water from entering your home where the chimney meets the roof. Properly installed and maintained flashing ensures your chimney remains waterproof, protecting your home from leaks and water damage. At Clean Sweep Chimney Services, we understand the importance of maintaining and repairing chimney flashing to keep your home safe and dry.

Chimney Flashing

Chimney flashing consists of metal sheets installed at the intersection of the chimney and the roof. Its primary function is to create a watertight seal that prevents water from seeping into your home. Flashing is typically made from durable and resistant materials such as aluminum, copper, or galvanized steel.

Types of Chimney Flashing

Step Flashing:
Installed in a stair-step pattern along the sides of the chimney where it meets the roof. Each piece of step flashing is tucked under a shingle to direct water away from the chimney.

Counter Flashing:
Installed over the step flashing and embedded into the chimney mortar joints. Counter flashing adds an extra layer of protection, ensuring a waterproof seal.

Base Flashing:
Placed at the base of the chimney where it meets the roof. It is often used with step flashing to create a continuous barrier against water infiltration.

Signs Your Chimney Flashing Needs Repair

Identifying the signs that your chimney flashing needs repair can help you address issues before they cause significant damage. Here are some common indicators that your chimney flashing may need attention:

  • Water Leaks:
    • If you notice water stains on ceilings or walls near the chimney, it could indicate that water is infiltrating your home, likely due to damaged or improperly installed flashing. Also, look for dampness or water pooling around the base of the chimney.
  • Rust and Corrosion:
    • Look for rust or corrosion on the flashing material. Rust weakens the flashing, compromising its ability to prevent water entry. Corroded flashing should be repaired or replaced to maintain its effectiveness.
  • Cracks and Gaps:
    • Gaps or cracks between the flashing and the chimney or roof allow water to seep in, leading to leaks and water damage. Sealing these gaps promptly can prevent further issues.
  •  Loose or Missing Flashing:
    • Flashing that has come loose or is missing pieces due to strong winds, heavy rain, or improper installation can cause flashing to become dislodged. Reattaching or replacing loose flashing is essential to restore a watertight seal.

Steps to Repair Chimney Flashing

Repairing chimney flashing involves several steps to ensure it is secure and functional. Here is an overview of the repair process:

Inspection and Assessment
A thorough inspection and assessment are the first steps in any flashing repair project. A certified Clean Sweep Chimney Services technician will examine the flashing to determine the extent of the damage and identify any underlying issues. This inspection helps decide whether the flashing can be repaired or needs to be replaced entirely.

Cleaning and Preparation
Before repairing the flashing, the area must be cleaned and prepared. This involves removing debris, rust, or old sealant from the flashing and surrounding areas. Proper preparation ensures the new flashing or repair materials adhere correctly and provide a durable solution.

Sealing Cracks and Gaps
Sealing the flashing with a high-quality sealant can restore its effectiveness for minor damage, such as small cracks or gaps. This step involves applying a waterproof sealant to the affected areas, ensuring a tight seal that prevents water infiltration.

Replacing Damaged Flashing
If the flashing is significantly damaged or corroded, replacing it with new flashing is the best option. The technician will remove the old flashing and install new pieces, ensuring they are correctly fitted and secured to create a watertight barrier. This process may involve installing step, counter, and base flashing to provide comprehensive protection.


Understanding the importance of chimney flashing repair is essential for maintaining a watertight and secure home. By recognizing the signs of damaged flashing and addressing them promptly, you can prevent serious risks and ensure your chimney remains in excellent condition.
