Chimney flashing is the metal that seals the joint where your roof meets the chimney.
Counterflashing sits in the brick and step flashing laps under the roofing. When either one rusts or lifts, water gets in.
Step flashing repair means replacing the small metal pieces lapped under the roofing along a chimney or sidewall.
Sealant alone won't last through the next storm, because lapped metal has to do the real work. If your roof is coming off anyway, the pro usually resets the flashing during the reroof.
Chester flashing repair starts by finding the metal that failed, then replacing it instead of smearing caulk over it.
The pro also checks the chimney crown, any kick-out flashing, and every new sealant bead to confirm the joints shed water.
Chimney flashing leak repair stops the water by replacing failed metal, not by adding more caulk.
A brown ring on a ceiling near the chimney usually means lifted flashing, not worn shingles. Book before the next storm so a local licensed pro can fix it before more rain runs through.
If water is coming in now, ask about emergency roof tarping.
Rust trails on the counterflashing often show up before any shingle looks worn. The metal is failing at the seam.
Stiff, shrunken sealant lets wind-driven rain find the gap fast. Lapped metal should do the work, not caulk.
A brown ring on the ceiling near the chimney or under a valley usually means lifted flashing. By the time you see it, the leak has often run through more than one storm.
The pro checks each point where the roof meets a chimney, wall, or valley for rust, gaps, and loose pieces.
Sound metal with a small gap gets resealed. Failed metal gets replaced, because sealant alone won't last.

The pro checks the chimney crown, any kick-out flashing, and every new sealant bead.
Most Simi Valley homes were built from the 1960s through the 1980s, so their original flashing has sat through decades of Santa Ana wind and summer sun. Repairing shingles around bad flashing just delays the same leak.
Simi Valley's Building & Safety Division treats reroofing and flashing repair as separate permit questions. A standalone fix around one chimney or sidewall often falls below the permit line. Resetting flashing during a larger reroof is folded into that job's scope.
Many 1970s and 1980s Simi Valley tract homes have composition shingle or clay tile. Tile flashing has to follow the tile profile, so the reglet in the mortar joint must sit at the right depth to keep counterflashing tucked in under wind.
Ballpark pricing for flashing & chimney repair around Simi Valley. Nothing is charged until you have a written estimate in hand.
| Underlayment Grade | Attic Airflow | Crew Availability |
|---|---|---|
| Manufacturer warranties on roofing materials and a contractor's labor warranty are two separate things, covering two separate failure points. A homeowner who understands which one applies to which problem asks better questions before signing anything. | Swaps cracked tiles or shingles in place, matches existing color where possible | an estimated $245–$1805 |
| Labor warranty terms vary by contractor, some running a year, others longer. Asking what happens if a leak turns up well after that window closes is a fair question, and how clearly it gets answered says something on its own. | Strips one layer, new underlayment and flashing, deck stays as-is | an estimated $350–$2470 |
| Manufacturer material warranties usually require correct installation to stay valid. That means a rushed or poor install can void coverage on shingles or tile that were never defective to begin with, leaving the homeowner to absorb the cost. | Complete reroof, new flashing and valleys, cool-roof rated material | an estimated $455–$3420 |
| Warranty terms belong in writing before the first tile or shingle comes off, not after. A verbal promise about what is covered carries no weight later, once there is disagreement about what actually failed and why. | Reroof with skylight flashing redone, no interior ceiling work | an estimated $630–$4940 |
A bid that looks low because it skips a permit is not a bargain — it can leave the work uninspected and the homeowner exposed if something fails later. Confirm permit status in writing rather than taking a verbal assurance.
Flashing seals a joint where two materials or angles meet, and that is where water concentrates. The metal flexes with heat and gets nailed through. Valley heat and wind loosen those seams well before the shingles wear out.
Reseal only when the metal is sound and the gap is small. New caulk does nothing for metal that has rusted or pulled loose. If the metal is compromised, reflashing with new, properly lapped pieces is the fix.
Often, yes. Tearing off the roof usually disturbs the counterflashing in the mortar joints, and reusing brittle metal risks a leak within a year or two. Most Simi Valley reroofs that include a chimney reset the flashing at the same time.
A cricket is a wedge-shaped structure built against the uphill side of a chimney. Without one, leaves and grit pile up and water backs up under the counterflashing. Hillside homes near Las Llajas Canyon see more of this buildup after windy weeks.
Usually not, since flashing alone is often small enough to fall under the permit threshold. If the work is part of a reroof, it falls under the reroof permit. Rebuilding or repointing the chimney itself is masonry and is looked at separately, so get the scope written down first.
Expect an estimated $350–$1900 per job for flashing & chimney repair around Simi Valley. Where you land inside that comes down to the number of squares, the pitch, and how easy it is to get a ladder and a dumpster to the house. The inspection is free, so you get a real figure rather than a guess.
Most roofs in this valley are not beaten by one dramatic event. They're worn down by daily heat cycling, dry wind pulling at loose edges, and years of sun exposure that quietly break down materials from the top layer inward.
Cedar shake demands more attention than a tile roof does. Here's what cupping, splitting, keyways, and spaced sheathing mean for a Simi Valley home, and when repair no longer holds up.

Both are metal roofs and they are not the same product. One hides its fasteners under a raised seam, the other shows them in rows across the pan. That single difference drives how each one ages, leaks and gets repaired.
