The Hidden Risks of a Worn Chimney Crown – What Bromsgrove Roofs Are Telling Us
The chimney crown – the cement layer that sits on top of your chimney stack – often goes unnoticed until problems arise. At Back to Back Roofing, we’ve repaired countless chimney crowns in Bromsgrove that were quietly causing leaks, damp patches, and internal water damage without the homeowner even realising it.
If you haven’t had your crown inspected in years, it might be time to schedule a chimney crown inspection in Bromsgrove before more serious problems develop.
What Is the Chimney Crown?
The crown is a sloped layer of mortar or concrete that seals the top of the chimney stack. Its job is to prevent rainwater from seeping into the brickwork and down the flue.
What Happens When It Wears Out?
- Cracks form that allow water into the stack
- Rainwater seeps down the flue causing damp fireplaces or stains
- Moisture damages chimney lining or causes brickwork to crumble
How We Fix It
We remove the damaged crown and rebuild it using frost-resistant, waterproof mortar. A properly finished crown includes an overhang to direct water away from the brickwork below. We can also fit chimney caps to further enhance protection.
Warning Signs of Crown Failure
- Cracks visible on the top of the stack
- Leaking chimney during or after rainfall
- Stains or damp patches near the fireplace
- Falling debris or mortar inside the chimney breast
If you’re unsure, book a chimney inspection today and let us take a closer look before winter sets in.
