Chimney flashing repair in Tulsa.
The chimney is the most common source of roof leaks in older Tulsa homes. The brick moves. The mortar cracks. The metal flashing that was tuck-pointed into those mortar joints pulls free. When someone caulks over it, the fix lasts two or three years. When the flashing is replaced and the mortar is tuck-pointed correctly, it lasts until the next re-roof.
Q: How do I know my roof leak is coming from the chimney flashing?
The old Midtown Tulsa neighborhoods, along with homes in the 74103 and 74105 ZIP codes, have brick chimneys that range from 40 to 80 years old. These chimneys have experienced hundreds of Oklahoma freeze-thaw cycles. Each cycle works the mortar joints slightly looser. Over decades, counter flashing that was originally embedded two inches into the mortar joint now sits in a gap that widens with every winter.
We have inspected chimneys in South Tulsa where the counter flashing was attached solely with a layer of tar that someone applied when the original mortar failed. That tar held for a few years. When it peeled, the entire chimney-to-roof transition was open. No step flashing visible, no mortar connection, just a gap.
We replace chimney flashing correctly. New step flashing interwoven with shingles on all four sides. Counter flashing cut and tuck-pointed into fresh mortar. Saddle at the uphill face if the chimney is wide enough to require it. That assembly, done right, lasts until the roof around it needs replacing. See our roof flashing page for other flashing types.
Five failure modes we repair.
Counter flashing pulled from mortar
The most common failure. Counter flashing that was tuck-pointed into mortar pulls free as the mortar deteriorates. The entire side of the chimney becomes an open water path.
Step flashing missing or corroded
Original step flashing that was never properly interwoven with shingles, or that has corroded through over decades of water contact, needs full replacement.
No saddle behind wide chimney
Water ponds behind chimneys wider than 30 inches without a saddle. That standing water accelerates every other failure on the list. If no saddle exists, it needs to be installed.
Caulk-only previous repair
Multiple layers of roofing caulk applied over failed flashing as a series of temporary fixes. When the caulk finally fails completely, the underlying structural failure is often worse than when it started.
Water staining inside near fireplace
Brown staining on the wall or ceiling near the fireplace or chimney breast is the interior symptom. The water is entering at the roof-to-chimney junction and traveling down through the wall assembly.
Replace the assembly, not just the sealant.
Assess the full assembly
Step flashing, counter flashing, saddle condition, mortar joint integrity. We photograph every element before we remove anything. This is the diagnostic record.
Complete checkRemove failed flashing
Old step flashing removed from under the shingles. Old counter flashing cut out of the mortar joints. We clear the existing assembly completely rather than building on top of failure.
Full removalInstall new flashing system
New step flashing interwoven with shingles on all four sides. New counter flashing cut, bent, and tuck-pointed into chased mortar joints. Saddle installed at uphill face if needed.
Correct assemblyDocument and warrant
Before and after photos of the complete assembly. Mortar tuck-pointing time given to cure before inspection. Written warranty on all flashing work.

We handle both the metal and the masonry.
Chimney flashing repair requires both roofing knowledge and masonry knowledge. The mortar tuck-pointing has to be right for the counter flashing to hold. The step flashing has to be properly integrated with the shingle course above it. When these two disciplines are handled by separate companies, things fall through the gap.
We handle both on the same crew. We cut, form, and install the metal. We tuck-point the mortar joints for the counter flashing. We integrate the new flashing with the existing shingle courses. One scope, one warranty, one company responsible for the result. That is how chimney flashing repair should work.
