A chimney repair checklist helps you record visible masonry, crown, cap, flashing, blockage and water concerns before requesting a professional assessment. It cannot prove that a concealed flue or liner is safe: a qualified chimney professional must inspect the accessible system, identify the defect and specify the repair.
Use the checklist below from a safe ground-level position, then turn your notes and photographs into a clear chimney repair estimate request. Keep the appliance and fuel, chimney history, inspection scope and inaccessible areas in the record.

Start with context. The same crack or stain can require a different response depending on the chimney construction, connected appliance and recent events. Record:
- Chimney type and material: masonry brick or block, factory-built metal, or another assembly, if known.
- Connected appliance and fuel: fireplace, wood stove, furnace, boiler or other appliance; note whether it burns solid fuel, gas or oil.
- Current use: whether the chimney is in service, disused or connected to a recently changed appliance.
- Recent events: appliance replacement, chimney fire, severe storm, earthquake, impact or known water intrusion.
- Timeline: when the condition was first noticed, whether it is worsening and where stains, dampness or debris appear.
Photograph visible conditions from the ground or another secure location. Do not climb onto a roof, chimney or ladder just to complete this checklist. Ask the inspector or contractor to state which portions were accessible and which were not. The Chimney Safety Institute of America (CSIA) describes Level 1 inspection procedures for routine annual inspection and cleaning when use has not significantly changed, while a Level 2 procedure adds accessible areas such as the attic and chimney top; local requirements can differ. Read the CSIA Level 1 procedure and CSIA Level 2 procedure for the stated scope.

What can I check safely from the ground?
A ground-level screening can flag conditions to report; it is not a diagnosis. Use binoculars or a camera with zoom if helpful, but do not treat an apparently sound exterior as evidence that the flue or liner is safe.
| Component | Visible observations to record | What to ask the professional to determine |
|---|---|---|
| Exterior masonry | Leaning profile, loose or missing bricks, open or eroded mortar joints, crumbling or spalling masonry, white deposits and visible cracks | Whether the condition affects structural stability, moisture resistance or only the surface, and what masonry repair is appropriate |
| Crown and top surface | Cracks, deterioration, missing sections and separation around a visible liner | Where water is entering, whether the crown is part of the problem and which compatible repair system is needed |
| Cap and flue termination | Missing, loose, damaged or obstructed cap; debris, nests or other visible blockage | Whether the cap is suitable for the flue, appliance and local requirements, and whether the flue itself is clear and intact |
| Roof flashing | Loose, missing, rusted or separated metal, broken seams, unsealed openings, punctures or previous patching | Whether the leak originates at the roof intersection, counterflashing, masonry, crown or another nearby detail |
| Interior symptoms | Stains, dampness, peeling finishes, odor, falling debris or evidence of water near the chimney | Whether the symptom is related to the chimney, roof, flue, liner or another building component |
The City of Redlands material inspection checklist identifies deteriorated masonry and mortar, unsuitable or damaged caps, and defective flashing as conditions needing further assessment. Those observations do not, by themselves, establish the cause or prescribe a product.

1Clear out junk files and repair common Windows errors2Scan for outdated or missing drivers - takes under a minute3Repair Windows errors before they cause bigger problemsHow do I assess exterior masonry without making a diagnosis?
Look for movement and loss of material, not just hairline surface variation. A chimney that appears to lean, has loose masonry or has large open joints warrants prompt professional evaluation because the defect may be structural.
- Stand at several safe viewpoints and compare the chimney’s vertical lines with nearby building lines.
- Record individual locations: for example, “open mortar joint on the north face below the roof,” rather than “chimney is failing.”
- Note whether bricks are missing, cracked, powdery, displaced or shedding pieces.
- Record white deposits (efflorescence), dark damp areas and interior staining as symptoms, not proof of a particular leak path.
- Photograph the full chimney and close views with a scale reference that does not require climbing.
Do not select mortar, sealant or a patching method solely from a photograph. The repair material must suit the masonry, exposure and cause of deterioration, and a leaning or unstable chimney may require a structural scope beyond repointing.
What should I check at the chimney cap, crown and flue termination?
Record whether the top assembly is present, secure, open and compatible with the flue. A missing or improper cap can justify evaluating an appropriately sized replacement, but a cap will not repair defective flashing, masonry, crown or liner.

- Is a cap present, and is it loose, bent, corroded, damaged or obstructed?
- Does the cap appear to fit the flue termination without blocking the opening?
- Are there visible cracks or deteriorated areas on the crown?
- Is there separation around a visible liner or signs that water can sit on the top surface?
- Are leaves, nests, masonry pieces or other material visible at the termination?
If you search for a replacement, the useful consumer phrase is chimney cap for masonry chimney, but purchase only after confirming the flue shape and dimensions, material suitability, required clearances and local requirements with a qualified professional. Do not assume a universal cap fits a rectangular masonry flue, a round liner or a factory-built system.
How can I tell when chimney flashing needs repair?
Flashing needs a source-focused assessment rather than a generic bead of caulk. Record visible loose or missing metal, rust, separated joints, broken seams, unsealed openings, punctures and previous patches, then ask the contractor to identify the actual water path.
- Photograph the chimney-to-roof intersection from a safe location.
- Record interior stains by room and ceiling or wall location, including when they appear (for example, after wind-driven rain).
- Note whether the flashing is visibly lifted, corroded, punctured or separated from masonry.
- Ask the estimate to distinguish base flashing, counterflashing, roof covering, masonry and crown work.
- Require the proposal to state how the water source will be verified and what areas are excluded.
A leak near a chimney can originate at the roof intersection, counterflashing, masonry, crown or another nearby building detail. The estimate should describe the specific repair scope and metal or system involved; repair methods vary by metal type and assembly.
What should a professional check when a chimney liner needs repair?
A surface checklist cannot reveal all internal damage. Ask a qualified inspector to assess blockage, deposits, liner condition, flue dimensions and route, and whether the flue is appropriate for the connected appliance and fuel.
The retrieved 2019 NFPA 211 text states that a liner softened, cracked or otherwise deteriorated so it can no longer contain combustion products must be repaired, replaced or relined with a suitable listed liner system or another approved material for the service. That document is the 2019 edition; verify the current standard edition and how your jurisdiction has adopted it before treating a provision as current local law.

When a contractor proposes liner work, ask for these details in writing:
- The appliance and fuel considered in the sizing decision.
- Flue dimensions, route and any relevant offsets.
- The observed liner defect and the evidence supporting it, such as photographs or inspection findings.
- The listed or approved liner system, material and intended service.
- The sizing basis and any required appliance or venting changes.
- Required inspections, permits or approvals and who is responsible for obtaining them.
These are planning questions, not a do-it-yourself liner specification. Do not use a cap, coating or short visible patch as a substitute for an assessment of a damaged liner.
When should I stop using the checklist and call a qualified professional?
Escalate rather than continue visual inspection when the chimney appears to lean or be unstable, masonry is loose, blockage is suspected, the liner may be damaged, water entry is significant or the flue condition is uncertain. A qualified agency should perform the inspection, and its scope should match the circumstances that prompted it, as described in the cited NFPA text.
- Leaning or movement: keep people away from the area and request structural evaluation.
- Loose or falling masonry: do not touch or remove pieces from a roof or chimney top.
- Suspected blockage: have the flue assessed before relying on the connected appliance.
- Possible liner failure: request an internal inspection and written repair or relining basis.
- Persistent or substantial water entry: request a coordinated roof-and-chimney diagnosis rather than a cosmetic patch.
- Unclear inspection scope: ask which portions were inaccessible and whether a higher-level inspection is warranted.
The absence of an exterior defect does not certify a concealed flue. A Level 2 inspection can include accessible attic and chimney-top observations in addition to the routine areas described for Level 1; the inspector should explain why that scope is or is not appropriate for your situation.

How should I compare two chimney repair proposals?
Compare the evidence and scope, not only the total price. A lower figure may omit access, flashing diagnosis, liner sizing, permits or closeout documentation that another proposal includes.
| Comparison question | What a complete proposal should show |
|---|---|
| What defect was found? | Photos or a precise written description tied to a component and location |
| How extensive was the inspection? | Accessible areas, inaccessible areas and the reason for the chosen scope |
| What repair method is proposed? | Specific masonry, crown, cap, flashing or liner work rather than “repair as needed” |
| Is the system compatible? | For a cap or liner, dimensions, material, appliance/fuel assumptions and sizing basis |
| Is the water source addressed? | Roof, flashing, counterflashing, masonry and crown responsibilities clearly separated |
| What logistics are included? | Access, protection, cleanup, exclusions, permits and inspections |
| How will completion be shown? | Closeout photographs, inspection records and approvals where required |
Ask follow-up questions in writing and keep the original photographs with the estimate. If the proposals describe different defects, obtain clarification or another qualified assessment before choosing a scope.

Closeout documentation should let a future owner or inspector understand what was observed and what changed. Keep:
- The dated inspection report and stated inspection level or scope.
- Before-and-after photographs organized by chimney component.
- Product or system identification for a cap, liner or other listed assembly.
- Descriptions of masonry, crown and flashing materials and repaired locations.
- Permit numbers, inspection approvals or other jurisdictional records, when applicable.
- Any limitations, inaccessible areas and recommendations for future inspection or maintenance.
Do not treat a completed exterior repair as proof that every concealed portion of the chimney was examined. The record should preserve that distinction.

Frequently Asked Questions
Can I inspect a chimney without getting on the roof?
Yes. Limit your own screening to safe ground-level views and photographs, and tell the professional which areas you could not see. A contractor can determine whether attic, roof or chimney-top access is needed without asking you to work at height.
Does replacing a chimney cap stop every leak?
No. A cap addresses the termination only. Water can still enter through crown deterioration, masonry, flashing, counterflashing or nearby roof details, so the source must be identified before selecting a repair.
What is the difference between a Level 1 and Level 2 chimney inspection?
The CSIA procedures describe Level 1 as routine inspection and cleaning scope when use has not significantly changed. Level 2 adds accessible areas such as the attic and chimney top; the appropriate level depends on the circumstances and local requirements.
Should a liner repair proposal name the appliance and fuel?
It should. Appliance type and fuel affect the liner’s suitability and sizing basis, so a proposal that omits those assumptions is difficult to evaluate. Ask the professional to document the flue route, observed defect and listed or approved system.
