If you find water damage, rust stains, or deteriorating mortar at your chimney’s lowest point, your chimney flashing may be in need of attention. At Keystone Roofing Ltd., we understand how important proper chimney flashing is in terms of preventing water damage to your home. Our team will find out whether your flashing needs a repair or replacement whenever the time comes. Common signs of needing chimney flashing service include:
We typically see chimney flashing lasting 15-17 years before needing replacement, though it's worth noting that harsh weather conditions and poor installation can greatly reduce its lifespan. We'd recommend regular inspections to maximise durability.
We recommend checking your specific policy as homeowner's insurance typically covers chimney flashing damage caused by sudden events like storms, but won't cover issues from regular wear and tear or poor maintenance.
We start with a practical assessment, explain the condition of the roof, and agree the right scope before work begins. You get updates during the job, daily site care where needed, and a final review before handover.
Timing depends on access, weather, materials, and the scale of the work, but our team keeps the process straightforward from first call to completion.
Speak with Keystone Roofing about your roof, get a clear assessment, and understand the next step before committing to work.

We don't recommend DIY chimney flashing installation. It's a complex job requiring specialised skills and tools. Without proper expertise, you could risk serious water damage and costly repairs. Let our experts handle it safely.
We often see these signs of poor chimney flashing: water stains on ceilings, rusted metal, loose or missing flashing pieces, cracked sealant, and visible gaps around the chimney base. Don't ignore these warning signs.
We recommend checking your specific policy as homeowner's insurance typically covers chimney flashing damage caused by sudden events like storms, but won't cover issues from regular wear and tear or poor maintenance.
We've seen how Cork's frequent rain, strong winds, and temperature fluctuations can loosen and damage chimney flashing over time. That's why we recommend regular inspections to prevent water damage and maintain your roof's integrity.
