RRB Roofing provides professional chimney repairs in Comber for residential and commercial properties with ageing mortar, damaged chimney masonry, flashing defects or water ingress. With over 50 years of combined roofing experience, our coverage includes Comber, Lisbane, Killinchy, Balloo, Ballygowan, Moneyreagh and surrounding communities around Strangford Lough.
A chimney remains exposed above the roof throughout the year, meaning its mortar, masonry and surrounding weatherproofing can deteriorate at different rates. RRB Roofing assesses the affected chimney before determining what work is required, with three dedicated services covering mortar joints, chimney-to-roof weatherproofing and water ingress.
Mortar that has begun to crack, erode or crumble can leave chimney joints increasingly vulnerable to continued weather exposure. Our Chimney Repointing service renews affected mortar where appropriate, helping maintain the existing stack and protect the surrounding masonry.
Where a chimney passes through the roof, flashing and leadwork help direct water away from the junction. Our Chimney Flashing & Leadwork Repairs address defective or deteriorated materials that may compromise this protection and contribute to leaks.
Water appearing around a chimney may have travelled from a defect that is not immediately visible. Our Chimney Leak Repairs assess the relevant masonry, mortar, flashing, leadwork and surrounding roof to help identify the route of water ingress before completing the required repair.
Comber is surrounded by a mixture of established residential areas and more open rural communities around Strangford Lough. Chimneys in these locations can experience significant exposure to wind and rain, making weathered mortar and vulnerable roof junctions important areas to monitor as properties age.
RRB Roofing uses more than 50 years of combined roofing experience to assess chimney problems in the context of the complete roof. Our approach is to identify what actually requires attention and provide a suitable repair, supported by free estimates, clear communication and before-and-after photographs on relevant work.
We base repair recommendations on the existing condition of the chimney, mortar, flashing and adjoining roofing rather than treating every chimney problem in the same way.
Our experience with both chimney and general roofing repairs helps when water ingress could originate from several different areas around the same roof junction.
Our Comber coverage extends into nearby villages and rural communities around the northern side of Strangford Lough. Customers throughout these locations can access chimney repointing, flashing and leadwork repairs and professional help with chimney leaks.
Find answers to common questions about chimney repairs around Comber, including weathered mortar, roof junctions, water ingress and repairs to existing chimney stacks.
Mortar is continually exposed to wind, rain and changing weather above the roofline. Over time, this exposure can cause joints to crack, erode or crumble, particularly on older or more exposed chimney stacks.
Many chimney problems can be localised. Where the existing stack remains suitable for repair, work may involve repointing affected mortar, repairing relevant brickwork or addressing flashing and leadwork rather than removing the entire chimney.
Several different materials meet around a chimney, and water can travel before appearing internally. The source may involve mortar, brickwork, flashing, leadwork or adjoining roofing, so the wider area needs to be assessed.
Yes. We provide chimney flashing and leadwork repairs and assess these materials alongside the surrounding roofing when investigating deterioration or water ingress.
