Chimney rebuild above the roofline: what it is and when you need it
Updated Sep 2026·National·Repair — masonry
What is a chimney rebuild above the roofline?
A chimney rebuild above the roofline takes the stack down to sound masonry and rebuilds it: new brick, new joints, a new crown, and new flashing where it ties into the roof. It is the standard answer for an exposed stack that is leaning, badly spalled or open at the joints along its whole run, where repointing would buy only a season.
When is it actually needed?
When the exposed stack has failed as a structure rather than in patches, or when it is no longer safe to leave standing.
What standard does it answer to?
NATIONAL · NFPA 211NATIONAL · IRC
- The International Residential Code (IRC) — the model building code for one- and two-family homes, adopted and often amended state by state and city by city.
- NFPA 211, the Standard for Chimneys, Fireplaces, Vents, and Solid Fuel-Burning Appliances — the national standard that sets the yearly inspection and the three inspection levels.
What should the invoice or report show?
Ask for a written scope: how far down the tear-out goes, what happens to the liner, and who reflashes the roof afterwards.
What does it cost?
Quote after inspection — no reliable national range

We checked 3 published sources (3 published cost guides). They either price this job case by case or disagree too widely to give an honest national number, so we show none. Expect a written quote after someone has looked at the chimney.
Does your state regulate this?
VARIES BY STATE
The IRC and NFPA 211 are national model documents, not state law: which edition applies to your home, if any, depends on the codes your state and city have adopted. Licensing, permits and what is allowed for a chimney rebuild above the roofline differ by state, and sometimes by city. Masonry rebuilds are among the chimney jobs most likely to need a contractor license or registration, a permit and an inspection. In several Southern states the license turns on the size of the job, through a dollar threshold. Our 50-state laws table and licensing by state set out what each state requires.
