Chimney Flashing Repair on Long Island — Homeowner Guide
Chimney flashing is the metal sealing system where your chimney penetrates the roofline. On Long Island's older housing stock — Cape Cods, colonials, and ranches built from the 1940s through 1970s — original flashing is often galvanized steel that has rusted through, or step-flashing systems that have separated from decades of freeze-thaw movement. Failed flashing allows water to run down the chimney into the attic, ceiling, and interior walls. It is the most common cause of chimney-related water damage in Nassau and Suffolk County homes.
Chimney flashing repair on Long Island typically costs $400–$1,200 depending on the size of the chimney, the extent of damage, and whether counter-flashing needs to be re-embedded in the mortar joints. Full flashing replacement using copper or stainless steel runs $800–$2,500. In many cases the adjacent roof decking and shingles must also be replaced, turning a flashing repair into a partial re-roof. Always have a licensed Nassau or Suffolk County roofing contractor inspect and quote the work.
