CHIMNEY FLASHING
Chimney flashing repair stops leaks, protects your roof, and prevents costly water damage. When flashing becomes loose, rusted, or improperly sealed, moisture enters the home. Repairing or replacing flashing ensures a watertight barrier and long-lasting chimney stability.
Chimney Flashing Repair
Chimney flashing repair is essential for preventing roof leaks, water damage, and structural deterioration around your chimney. Flashing is the metal barrier installed where the chimney meets the roof, creating a watertight seal. Over time, flashing can loosen, rust, crack, or separate from the chimney, allowing water to seep inside. Repairing or replacing damaged flashing protects your home, prevents interior leaks, and ensures long-term roof and chimney stability. Just like any exposed roofing component, chimney flashing requires periodic inspection and timely repair to avoid costly damage.
When Chimney Flashing Repair Is Needed
Chimney flashing repair is needed when you notice water stains on ceilings or walls near the chimney, moisture in the attic, rusted flashing, or shingles lifting around the chimney base. These issues often appear after heavy rain, seasonal storms, aging roofing materials, or improper installation. You may also need flashing repair if you see cracked sealant, gaps where the chimney meets the roof, or signs of masonry deterioration caused by water intrusion. Any visible moisture, discoloration, or roof damage around the chimney indicates flashing failure and should be addressed immediately to prevent further problems.

How Chimney Flashing Repair Works in 3 Steps
Step 1: Inspection & Leak Detection
The technician begins by inspecting the chimney base, surrounding shingles, and roof penetration area to locate the source of the leak. We check for rust, lifted metal, missing sealant, or improper installation. Moisture meters may be used to confirm hidden water damage. We also evaluate the condition of the roof, chimney masonry, and surrounding materials to ensure no additional repairs are needed.
Step 2: Flashing Repair or Full Replacement
Depending on the damage, we either reseal, reinforce, or fully replace the flashing. Minor issues may involve resealing seams, correcting loose sections, or applying waterproof barriers. If the flashing is severely rusted, bent, or improperly installed, we replace it entirely with high-quality metal flashing designed to provide long-term protection. All installation is completed to create a secure, watertight seal between the chimney and the roof.
Step 3: Final Water Test & System Check
After repairs are complete, the technician performs a final water test to verify that the leak has been resolved. We check for proper sealing, secure attachment, and complete protection around the chimney base. If additional moisture issues or masonry damage are discovered, we provide clear recommendations for follow-up service to ensure long-term stability.
Recommended Follow-Up Services
Common follow-up services after flashing repair include: Chimney Waterproofing — to protect masonry from future moisture intrusion, and Chimney Crown Repair — if water damage extends to the top of the chimney. These services help ensure your chimney remains fully protected and leak-free.
