What Chimney Flashing Repair Involves
Chimney flashing repair restores the metal seal where a chimney passes through the roof. That joint is one of the hardest places on a roof to keep watertight. Shingles cannot seal against masonry on their own, so the flashing carries water around the chimney and back onto the roof surface.
- Step flashing: pieces woven in with the shingles along the sides of the chimney.
- Counter flashing: a cap set into the masonry that overlaps the step flashing.
- Front or apron flashing: the piece along the downslope face of the chimney.
- Back flashing or a cricket (saddle): the upslope side, where water and debris collect against the chimney.
Signs a Chimney Flashing Repair May Be Needed
Chimney flashing problems often show up first inside the house, not on the roof. Watch for water stains on the ceiling or walls near the chimney. Damp spots in the attic around the chimney chase are another clue. So are drips that appear only during or after heavy rain.
- Ceiling or wall stains close to the chimney
- Moisture or staining on attic framing around the chimney
- Flashing that is lifted, bent, corroded or separated from the masonry
- Cracked or missing sealant along the flashing edges
- Damaged or missing shingles beside the chimney
Chimney Flashing Repair, Re-Flashing or Larger Roof Work: A Decision Table
Chimney flashing repair can mean a small fix or a full rebuild of the flashing, and the right choice depends on the roof around the chimney. The table below is general guidance to help you follow the conversation during an assessment. It is not a diagnosis.
| What the inspection finds | Option usually discussed | What to ask |
|---|---|---|
| One loose or lifted section, with the rest of the flashing and shingles in good shape | Targeted flashing repair | Which pieces are being refastened, resealed or replaced? |
| Corroded, bent or poorly layered flashing on several sides | Full re-flashing of the chimney | Will step, counter, apron and back flashing all be replaced? |
| Water damage to the decking or sheathing under the flashing | Re-flashing plus decking repair | How much decking will be opened up, and how is extra damage handled? |
| Worn shingles across the whole roof, not just near the chimney | Flashing work as part of a roof replacement | Does it make sense to wait and re-flash with the new roof? |
| Upslope side that traps water or debris against the chimney | Back flashing or cricket work | How will water be directed around the upslope side? |
What Affects the Cost of Chimney Flashing Repair (Estimate Guide)
Chimney flashing repair costs depend on the scope found on the roof, so no single price fits every chimney. King Roof Care provides transparent estimates before any work begins. The written estimate lists the exact scope and materials, so you can see what drives the number.
- Extent of the work: a single section versus full re-flashing on every side.
- Roof material: details differ between composition, asphalt shingle, wood shake, presidential shingle, PVC and metal roofs. King Roof Care works with all of these.
- Chimney size and position: wide chimneys and chimneys mid-slope need more flashing pieces and more care on the upslope side.
- Hidden damage: wet or soft decking found during the repair adds to the scope.
- Shingle condition: brittle or damaged shingles around the chimney may need replacing so the new flashing can be layered in correctly.
- Roof pitch and access: steep or hard-to-reach roofs take more setup.
How to Prepare a Chimney Flashing Repair Request
A chimney flashing repair request goes faster when you share clear details from the start. A few notes and photos help the assessment focus on the right area of the roof and the attic.
- Where the water shows up inside (room, ceiling, wall, attic) and when it appears (during rain, after rain, in windy storms).
- Ground-level or window photos of the chimney and the flashing around it.
- Photos of interior stains, with a coin or tape measure in the frame for scale.
- The roof material and, if you know it, the rough age of the roof.
- Any past repairs or sealant applied around the chimney.
- Whether the leak started after a storm, so storm-related damage can be considered.
- Access notes: gates, pets, parking, and whether the attic can be reached.
How to Compare Chimney Flashing Repair Estimates
Chimney flashing repair estimates can look similar on price but cover very different work. A written estimate from King Roof Care lists the exact scope and materials. Use the checklist below to put any quotes side by side and spot the gaps.
- Does the estimate name each flashing part being repaired or replaced (step, counter, apron, back flashing or cricket)?
- Does it state the flashing material and any underlayment or ice-and-water protection around the chimney?
- Is sealant listed as a supplement to properly layered flashing, or as the whole repair?
- Does it explain how damaged decking or sheathing will be handled if found?
- Does it include replacing shingles around the chimney where needed?
- Does it describe cleanup and protection of landscaping, decks and patios?
- Is the contractor registered with Washington L&I, and can you verify the registration yourself?
Chimney Flashing Repair Mistakes That Lead to Rework
Chimney flashing repairs most often need to be redone when the scope was too narrow for the problem. As general guidance, the patterns below are worth raising during any assessment.
- Treating sealant as the only fix when the flashing itself is lifted, corroded or layered wrong.
- Repairing one side of the chimney while the leak actually comes from the upslope side.
- Replacing flashing without checking the decking underneath for water damage.
- Reusing brittle shingles around the chimney, so the new flashing cannot be woven in cleanly.
- Fixing the flashing without confirming it is the source of the leak, when a vent, skylight or valley nearby is to blame.
- Skipping a follow-up look at gutters and nearby flashing. King Roof Care's roof inspections check gutters along with shingles and flashing.

Frequently asked questions
What is chimney flashing?
Chimney flashing is the metal system that seals the joint between a chimney and the roof. It directs water around the chimney instead of into the roof deck. It usually combines step flashing along the sides, counter flashing set into the masonry, apron flashing at the front, and back flashing or a cricket on the upslope side.
How much does it cost to fix flashing on a chimney?
The cost to fix flashing on a chimney depends on the scope found on the roof. Key factors are whether one section or the whole chimney needs work, the roof material, chimney size and position, and any hidden decking damage. King Roof Care starts with a free, no-obligation assessment. You then get a written estimate with the exact scope and materials before any work starts.
