How Much Does Chimney Flashing Repair Cost in Texas?
Updated: October 2026
Chimney flashing repair in Texas typically costs $200 to $1,600 as of October 2026, depending on whether the job is a simple reseal or a full flashing replacement. A simple reseal runs $150 to $400. Replacing one section of step flashing runs $300 to $700. A full reflash of a standard chimney runs $500 to $1,500 in galvanized steel, and copper pushes it to $1,000 to $2,500 or more. Large or stone chimneys can exceed $2,000.
What do Texas roofers charge for each type of flashing job?
National numbers are a decent starting point. Angi reports a national average of $1,000 with most homeowners spending $400 to $1,600 (updated September 2026). Contractor-level pricing for 2026 breaks down more usefully by job type:
| Job type | Typical cost as of 2026 | When it fits |
|---|---|---|
| Spot reseal or re-securing | $150 to $400 | Small gaps, cracked sealant, minor lift |
| Step flashing section replacement | $300 to $700 | Corrosion or damage limited to one side |
| Full reflash, galvanized steel | $500 to $1,500 | Widespread rust, repeated leaks, aging system |
| Full reflash, copper | $1,000 to $2,500+ | Premium durability, visible historic chimney |
| Add a cricket or saddle | $400 to $900 | Wide chimney (over 30 inches) with no diverter |
One pattern across every source: labor is 60 to 70 percent of the total bill. The metal itself is modest in price even for copper. You are paying mostly for the time and skill to remove shingles, fit the metal, and work it into the chimney masonry properly.
Why does my chimney leak at the flashing, not the shingles?
A chimney is a masonry box punched through a waterproof roof. The roof and the chimney move differently as the house settles and temperatures change. Flashing is the metal bridge built to slide with that movement while still shedding water, and it usually works for 20 to 30 years. It fails at predictable points. Step flashing loosens as its fasteners corrode over 15 to 20 years. Counter flashing pulls away from the mortar joint as the mortar deteriorates. Sealant dries and cracks. Gulf Coast salt air can corrode metal flashing faster than inland installations. For the full breakdown, see our chimney flashing leak repair guide.
Can you tell a reseal job from a replacement job?
This is the question that matters most for your wallet, because a $250 reseal and a $1,200 reflash are answers to different problems. A reseal is enough when the metal itself is sound and only the sealant, caulk joints, or a lifted counter flashing tab has failed. A competent repair at this level can extend the life of an otherwise healthy flashing system by five to ten years.
A full reflash is the right call when the metal is corroded or separated across the whole chimney, when a past repair used roof cement as the main waterproofing and it has cracked through, or when leaks keep returning to the same spot despite earlier patches. Ask the roofer which of the four parts are actually failing before agreeing to a full reflash price.
What makes one quote higher than another?
The size of the chimney is the biggest cost driver. A standard chimney around 3 by 3 feet with easy ladder access is the baseline job. A two-story chimney above a steep pitch can add staging costs. The system involved matters too: replacing one section of step flashing is cheaper than rebuilding counter flashing into the mortar joints, which requires cutting a new groove into the masonry.
Hidden damage is the wildcard. If water has been getting past the flashing for a while, the repair can grow to include wet decking, fascia, or soaked insulation. This is the most common reason a flashing bill doubles mid-job. See our roof leak repair cost factors for what a written estimate should cover before you agree to anything.
Is a cheap reseal quote ever the right choice?
Sometimes yes, and this is where the math helps. Here is the comparison worth doing:
- Reseal at $200 to $400 buys five to ten years on flashing whose metal is still sound. Cost per year of protection is very low.
- Full reflash at $500 to $1,500 resets the clock to 20 to 30 years, but you are paying three to seven times more for metal that may still have a decade of life in it.
- Repeated reseals that fail within a year or two are the losing bet. Two or three failed patch jobs can total more than one proper reflash, and the water damage meanwhile keeps growing.
The dividing line is the condition of the metal, not the size of the leak. A small leak through corroded flashing needs replacement. A big stain from a simple sealant gap may need only a reseal. Ask the roofer to photograph the flashing so the price matches what they found.
Will homeowners insurance cover chimney flashing repair?
It depends on the cause, not the component. Flashing damaged by wind or hail is often covered, minus your deductible. Flashing that failed from age or poor installation is usually excluded as wear and tear. Photograph everything before the repair, because storm damage plus age corrosion can turn into a gray-area fight with the adjuster.
If your flashing is failing now and you are unsure whether storm damage is involved, it is worth reviewing how flashing repair costs are quoted and then getting a local inspection. An independent provider in Texas City or Galveston County can trace whether the chimney is really the source and give you a written quote with no pressure. Call (409) 290-5353 to check availability.
Frequently Asked Questions
How much does it cost to reseal chimney flashing?
Resealing chimney flashing typically costs $150 to $400 as of 2026, depending on roof access and how many joints need attention. It is the right fix when the metal is sound and only the sealant or a lifted tab has failed. A proper reseal can add five to ten years to a healthy flashing system.
How much does it cost to replace chimney flashing completely?
A full chimney flashing replacement typically costs $500 to $1,500 in galvanized steel as of 2026, or $1,000 to $2,500 in copper. Large or stone chimneys can exceed $2,000. Labor is 60 to 70 percent of the total, since the metal itself is modest in price and the skilled work is fitting it into the masonry.
How long does chimney flashing last?
Chimney flashing typically lasts 20 to 30 years. Step flashing fasteners often corrode first, around the 15 to 20 year mark. Salt air near the Gulf Coast can shorten metal life. If your flashing is under 20 years old and sound, a reseal is usually enough; past 25 years with recurring leaks, a full reflash is the smarter money.
Does a chimney leak always mean the flashing is bad?
No. A cracked chimney crown or deteriorated mortar can let water in above the roofline entirely, and it will look exactly like a flashing leak inside the house. A thorough inspection checks both the flashing system and the chimney structure itself before quoting a repair, so you are not paying to fix the wrong thing.
