Chimney Cap Replacement:

Why It Might Be Time to Remove the Whole Chimney Instead

Brick Chimney Removal Hamilton

Key Takeaways:


  • Chimney cap replacement is often a temporary fix if the rest of your chimney is compromised.
  • Chimney flashing repair can stop leaks, but only when the chimney structure is still sound.
  • Golden Horseshoe Roofing offers brick-by-brick chimney removal and full roof restoration afterward.
  • Many companies stop at demolition — we finish the job by patching the roof to match.
  • Based in Hamilton, ON, we specialize in long-term solutions, not quick band-aids.

What Is a Chimney Cap & When Should You Replace It?


A chimney cap is a metal covering that sits atop the flue. It prevents water, animals, debris, and snow from entering your chimney — and yes, even sparks from escaping.


Over time, these caps rust, come loose, or fall apart. That’s when many homeowners start searching “chimney cap replacement.”


But here’s the truth no one’s telling you:


If your chimney cap is failing, it could be a sign of a much larger problem with the entire chimney structure.


When a Chimney Cap Replacement Isn’t Enough


A deteriorating cap often signals:


  • Cracked or crumbling bricks
  • Damaged mortar joints
  • Rusted or detached flashing
  • Water leaks into the attic or home


Replacing the cap alone may not solve any of these issues — and could leave you with a false sense of security until the next storm exposes the real damage.

That’s why, in Hamilton’s older homes — especially in areas like Stoney Creek, Dundas, and the lower city — we’re seeing more customers opting for complete chimney removal.


What About Chimney Flashing Repair?


Great question. Chimney flashing is the metal (usually aluminum or galvanized steel) that seals the base of your chimney to your roof. When installed poorly or left unattended, water gets in — and you know the rest.


At Golden Horseshoe Roofing, we:


  • Inspect chimney flashing during every roof assessment.
  • Perform chimney flashing repair when the brick structure is still solid.
  • Recommend full chimney removal when the masonry is crumbling and beyond repair.

In fact, many of our roof leak repair calls in Hamilton come down to two things: flashing failure or rotted decking where a chimney used to be.


Real Job Example: 3-Storey Chimney Removal Done Right


We recently tackled a three-storey brick chimney removal in Hamilton — and the process was anything but your typical “hack and haul.”


Here’s what we did:


  • Removed the chimney brick-by-brick to below the roofline — no collapsed bricks or debris damage.
  • Patched the roof deck with new plywood.
  • Shingled the patched area, carefully matching the existing colour for a seamless look.
  • Cleaned up the job site and left the homeowners leak-free and happy.

What Most Companies Do (And Why It’s a Problem):


  • Smash the chimney quickly without care for surrounding shingles or structural integrity.
  • Leave an open hole in the roof and tell the homeowner to “call a roofer” afterward.
  • Ignore flashing entirely.

That’s where Golden Horseshoe Roofing steps in — we’re roofers first, which means your home doesn’t get left half-done.


Why Chimney Removal + Roof Patching Is Often the Best Long-Term Fix


If your chimney isn’t being used (no active fireplace, or switched to a vented furnace), it may be:


  • A heat loss point in your home
  • A source of water infiltration
  • Structurally unsound


In these cases, a full removal and professional patch job can:


  • Lower your heating bills
  • Prevent costly repairs down the road
  • Improve the look and value of your roof


And remember: not all roofing contractors offer chimney removal — and even fewer do it safely and correctly.
