For a roof leak around a chimney in the Los Angeles area, the cost to repair the flashing typically ranges from $300 to $800 for a standard job.

To fix a leaking chimney flashing, first inspect the area for cracks, gaps, or lifted edges. Clean the flashing and surrounding shingles thoroughly. Apply a high-quality, rubberized roofing cement under the lifted edges and over any nail heads. For larger gaps, use a metal flashing repair patch secured with roofing nails and sealed with cement. Ensure the counter-flashing (embedded in the chimney mortar) is intact; if loose, re-mortar it. For complex issues, California Green Roofing recommends consulting a professional to avoid improper sealing that can trap moisture. Always prioritize safety and check for hidden damage to the chimney structure.
