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.

FAQs

  1. What is a chimney crown?
    It’s the top layer of concrete or mortar that seals the chimney stack and protects it from rain and weather.
  2. Is the chimney crown the same as the flaunching?
    No – flaunching secures chimney pots, while the crown covers the stack top as a whole.
  3. How do I know if the crown is damaged?
    You might see visible cracks, water leaks, or damp spots inside near the fireplace.
  4. How long should a chimney crown last?
    Properly built crowns can last 25+ years, but weather exposure can shorten that lifespan.
  5. Can the crown be repaired or must it be replaced?
    Minor cracks can be sealed, but widespread damage often requires a full rebuild.
  6. Does insurance cover chimney crown damage?
    Sometimes, if it’s linked to storm damage – we can assist with documentation.
  7. Do you fit chimney caps?
    Yes – we highly recommend installing a cowl or cap for added protection.
  8. How long does crown repair take?
    Most chimney crown rebuilds are completed in 1–2 days.
  9. Is scaffolding required?
    For taller properties, yes – we’ll include this in your quote if needed.

Brickwork or Flashing? The Real Cause of Your Chimney Leak in Bromsgrove

Brickwork or Flashing The Real Cause of Your Chimney Leak in Bromsgrove

Brickwork or Flashing? The Real Cause of Your Chimney Leak in Bromsgrove

Dealing with a chimney leak? Many homeowners assume the issue is with their roof, but more often than not, it’s the chimney itself – either the brickwork or the flashing. At Back to Back Roofing, we help property owners across Bromsgrove pinpoint and repair the real cause of chimney leaks – before they get worse.

If you’re unsure whether it’s time for chimney repairs in Bromsgrove, here’s what to look for and how we can help.

1. Damaged or Deteriorated Flashing

Flashing is the metal seal that connects the chimney base to your roof. Over time, lead flashing can crack, lift, or deteriorate, allowing rainwater to seep through and cause interior damp patches or ceiling stains.

2. Cracked Brickwork or Missing Mortar

Exposed brickwork can absorb moisture, especially when mortar joints start to fail. This leads to internal damp and even frost damage in winter. We offer full brickwork and repointing services to restore integrity and stop leaks at the source.

3. A Combination of Both

In many cases, the leak is caused by a mix of issues: compromised flashing *and* weakened masonry. We always conduct a full inspection before starting work to ensure all issues are addressed in one visit.

What Can Be Done?

  • Install or replace lead flashing
  • Repoint brick joints with weatherproof mortar
  • Seal or cap the chimney pot if needed

FAQs

  1. How do I know if it’s the chimney leaking or the roof?
    Leaks near chimney breasts or water stains running down inside walls are often chimney-related. We’ll inspect and confirm the source.
  2. What is chimney flashing?
    It’s a lead barrier that seals the gap between your chimney and roofline to prevent water ingress.
  3. Can flashing be repaired or must it be replaced?
    We can patch small areas, but complete replacement is more effective for older or cracked flashing.
  4. How do bricks let in water?
    When mortar joints break down, water seeps through cracks, especially in heavy rain or frost.
  5. Can a leak cause internal ceiling stains?
    Yes – chimney leaks often lead to damp patches in lofts, ceilings, or upper walls.
  6. Do chimney leaks affect energy efficiency?
    Absolutely – leaks cause drafts and moisture that can reduce insulation performance.
  7. How long does a chimney flashing repair take?
    Usually one day or less, depending on roof access and weather.
  8. Do you guarantee chimney leak repairs?
    Yes – all work is guaranteed for quality and durability.
  9. What materials do you use?
    We use industry-approved lead flashing, weatherproof mortar, and high-quality bricks when needed.
