Leave the building and call from outside — that is an emergency services call, not a service call. A blocked or failed flue is one of the ways carbon monoxide reaches a living space, and headaches that clear when you leave the house point the same way. If you have had a chimney fire — a roaring sound, dense smoke, or debris on the roof — do not light another fire until the flue has been inspected.

Chimney Flashing Repair in San Antonio
Two things shape chimney work in San Antonio: the age of the building stock, and what the weather does to masonry that has been standing in it for decades. The chimney is rarely the thing that changed — what changed is usually what vents into it.
69% of homes in San Antonio heat with electricity, so a fireplace here is used by choice rather than by necessity and tends to be inspected far less often. (US Census ACS 2022)
Coordinating with a reroof
Texas roofs get replaced often, frequently after hail. The best moment to redo chimney flashing is while the roof is open, and the worst outcome is a roofer laying new shingle over old flashing.
After a hail claim
Mass roof replacements happen at speed, and the chimney detail is what gets rushed. If your roof was replaced on a claim, the flashing is worth looking at.
Telling flashing from crown
Flashing leaks appear with wind-driven rain and often stop in ordinary showers. Crown leaks appear whenever it rains.
Two layers, not a smear of cement
Correct flashing is step flashing woven in with the roof courses as they climb the chimney, plus counter-flashing let into a groove cut in the mortar and folded down over it.
What is usually there is roof cement troweled across the junction. It looks like a repair for a season, then it cracks — and in Texas it cracks faster, because the joint underneath is moving with the soil as well as with temperature.
The reglet is what lasts
Counter-flashing must be cut into the mortar, not stuck to the surface. Surface-mounted metal held with sealant fails when the sealant does.
Detailing for movement
Where a chimney is separating from the house seasonally, the counter-flashing has to have enough lap to accommodate that movement rather than being pinned tight. A flashing detailed as though nothing moves will fail on the first wet-dry cycle.

Chimney Flashing Repair in San Antonio — FAQs
What chimney problem is most common around San Antonio?
Gas log sets serviced never, because nobody counts them as an appliance. That pattern is regional rather than universal — san Antonio, Corpus Christi, Laredo, McAllen and the Rio Grande Valley. It is worth knowing before you book, because it tells you what someone should be looking hardest at here.
How much does chimney work cost in San Antonio?
It depends entirely on what the chimney turns out to need, and the spread is wide. Sweeping, an inspection, a cap or a damper repair are the inexpensive end and are usually done in one visit. Relining, rebuilding above the roofline and full crown recasting are the expensive end. Nobody can quote it honestly over the phone, which is why the inspection comes first. The contractor you are introduced to sets their own prices and agrees them with you directly.
Do you cover all of San Antonio?
Yes — all 88 ZIP codes in San Antonio and the surrounding towns. Tell us where you are and we put you in touch with a company that covers it.
How quickly can someone get to me in San Antonio?
For a routine inspection or sweep, usually within a few days, and sooner outside the fall rush. Late spring through early fall is the quiet season and the easiest time to book. If you have had a chimney fire, or you can smell gas or have a carbon monoxide alarm sounding, that is not a scheduling question — leave the building and call emergency services from outside.
My fireplace smokes into the room. What is wrong?
Several possible causes, and they need different work. A blocked cap or arrestor, a damper not opening fully, a smoke chamber that was never parged, a flue too small for the fireplace opening, or a chimney too short relative to the roof around it. A house sealed tight enough to run under negative pressure will also pull air down the flue. An inspection separates them; guessing does not.
Should the chimney be repaired or rebuilt?
It depends how far the damage goes. If a key scrapes mortar out but the brick is intact, that is repointing. Once brick faces have flaked through, a brick can be rocked by hand, or the stack leans, repointing has nothing sound to bond to and a rebuild is the honest answer. Most rebuilds stop at the roofline, because that is the section taking weather from every side.
How long should flashing last?
Properly detailed metal outlasts the roof covering. Sealant gives a season or two here.
Roofer or chimney company?
Either, provided they cut a reglet and detail for movement.
