Roof Repairs & Leaking Chimney – Cwmbran

We were recently contacted by a homeowner in Cwmbran, after they noticed damp patches forming on an upstairs bedroom ceiling, directly below their chimney breast. After a professional inspection, it became clear that their chimney flashing had deteriorated over time, allowing water to penetrate during heavy rainfall. Left untreated, the issue could have caused more extensive internal and structural damage.

As specialists in roofing in Cwmbran, our team was brought in to carry out a full repair and ensure the property was properly weatherproofed.

Requirements

Following an initial site survey, we identified the following requirements:

• A thorough inspection of the chimney stack and surrounding roof area
• Replacement of damaged flashing and repair of cracked mortar joints
• Weatherproof sealing to prevent further water ingress
• Repair of a few damaged slates adjacent to the chimney
• A long-term solution, avoiding the risk of recurring leaks

Solution

After setting up safe roof access, our team carried out a full chimney inspection. We identified perished lead flashing and deteriorated pointing around the brickwork as the main causes of the leak.
The following works were completed:

• Removal of old, damaged flashing
• Installation of new lead flashing, expertly cut and chased into the brickwork
• Repointing of the chimney stack with high-quality weather-resistant mortar
• Replacement of cracked and slipped slates around the chimney base
• Final waterproof sealant applied to ensure long-lasting protection
• All work was completed within three days, minimising disruption to the household.
