Chimney Crown & Flashing Repair in Pittsburgh
Stop Water Damage Before It Starts
At West Penn Fireplaces & Chimney, we see it all the time—small cracks and failed seals that turn into major, expensive chimney repairs.
Your chimney crown and flashing are your home’s first line of defense against water intrusion. When they fail, water gets in—and that’s when real problems begin.
Why This Matters
Water is the #1 cause of chimney deterioration. Once moisture enters your system, it can quickly lead to:
- Cracked and deteriorating masonry
- Rusted dampers, fireboxes, and liners
- Interior leaks and ceiling damage
- Mold and moisture issues
- Freeze/thaw damage during winter
The good news: these problems are preventable with proper crown and flashing maintenance.
What Is a Chimney Crown?
The chimney crown is the concrete slab at the very top of your chimney. It’s designed to:
- Shed water away from the chimney structure
- Protect the flue opening
- Seal the top of the chimney
Common Chimney Crown Issues:
- Cracks or separation
- Poor original construction
- Deterioration from weather exposure
- Missing or inadequate overhang
Even small cracks allow water to seep in and expand during freeze/thaw cycles—causing rapid damage.
What Is Chimney Flashing?
Flashing is the metal barrier that seals the joint where your chimney meets the roof.
It typically consists of:
- Step flashing (along the roofline)
- Counter flashing (embedded into the chimney)
Common Flashing Problems:
- Rust or corrosion
- Loose or lifted sections
- Improper installation
- Failed sealant
When flashing fails, water can enter directly into your roof and attic—often going unnoticed until damage is severe.
