What it costs
Chimney flashing repair costs $300–$1,200 in New Jersey. Resealing sound flashing is at the bottom of that range; stripping and replacing failed step and counter flashing, which usually means lifting shingles, is at the top. Flashing is the single most common source of a « chimney leak » — the ceiling stain around the chimney is far more often the flashing than the chimney.

What moves the price
These are the things that actually change the number. If a quote is far outside the range above, one of them is usually the reason — and it is fair to ask which.
| Factor | Why it changes the price | Effect |
|---|---|---|
| Reseal or replace | If the metal is sound and only the sealant has failed, a reseal buys years cheaply. Rusted or lifted flashing has to come out. | Largest swing |
| Roof material | Asphalt shingle is the straightforward case. Slate, cedar shake and tile all cost more because the roof has to be opened carefully and put back. | Moderate |
| Whether the counter flashing is cut in | Properly done, counter flashing is cut into a mortar joint rather than surface-sealed to the brick. Doing it correctly costs more once and stops the annual reseal cycle. | Moderate |
| How long it has leaked | A leak caught this season is a flashing job. One that has run for years may have brought decking and framing damage with it. | Minor |

A job like this
A typical job of this kind, start to finish, with what each part costs. The figures add up — you can check the arithmetic.
A Red Bank homeowner calls in April after a wet March. A brown ring has appeared on the bedroom ceiling where the chimney passes through, and it grows a little after every storm — but only when the wind comes from the south-east.
$850, inspection credited. Middle of the $300–$1,200 range: full replacement rather than a reseal, but a straightforward asphalt shingle roof. Slate or cedar shake would have pushed it toward the top, because the roof has to be opened and put back by hand.

Included
Insurance
Flashing that failed from age is maintenance and is not covered. Flashing torn off in a named storm usually is. The distinction matters more here than on most chimney work, because flashing damage is very often storm-related on the Shore — if a nor'easter took it, document the date and the damage before anyone touches the roof.
