You’ve just noticed water stains creeping along your ceiling near the fireplace. After a heavy Texas rainstorm, the damp spot spreads quickly. Many homeowners think of shingles when it comes to roof leaks—but often the culprit is chimney flashing.
Chimney flashing is the thin sheet metal installed where the chimney meets the roof, and its job is simple: keep water out. When flashing fails, water seeps into your attic, walls, and ceiling, causing hidden damage that gets expensive fast.
If you’re wondering, “How much does it cost to replace chimney flashing in Texas?” you’re not alone. At Pete’s Builders, we help homeowners across Dallas, Fort Worth, Houston, Austin, and San Antonio understand the true costs of flashing replacement—and how the right repair saves thousands in long-term roof damage.
This guide breaks down the average chimney flashing replacement cost, factors that affect price, regional differences across Texas, and why professional replacement is worth the investment.
Why Chimney Flashing Matters
Your chimney is one of the most vulnerable points on your roof. Without proper flashing:
- Rainwater finds its way under shingles and into the attic.
- Wood structures rot over time.
- Mold and mildew develop, creating health risks.
- Fireplaces and chimneys become unsafe.
In Texas, where storms roll in suddenly and roof systems face scorching summers, flashing wears out faster than in many other states. A well-installed chimney flashing protects your roof and gives you peace of mind.
