RRB Roofing provides professional chimney leak repairs in Belfast for residential and commercial properties affected by water ingress around chimney stacks. With over 50 years of combined roofing experience, we investigate the chimney, flashing, mortar, brickwork and surrounding roofing to identify the likely source of the leak and carry out the appropriate repair.
Water appearing around a chimney can have several possible causes, and the visible damp inside a property may not reveal exactly where rainwater is entering. Our chimney leak service focuses on locating the source, repairing vulnerable chimney areas and addressing problems where the chimney meets the surrounding roof.
Finding the source of a leaking chimney is essential before deciding what needs to be repaired. Our Chimney Leak Detection assesses the relevant parts of the chimney and adjoining roof to identify defects that may be allowing rainwater into the property.
Deterioration to mortar, brickwork and other exposed chimney areas can reduce their resistance to Northern Ireland's wind and rain. Our Chimney Weatherproofing Repairs address affected areas where appropriate to help restore protection against water penetration.
The point where a chimney passes through the roof relies on effective flashing and leadwork to keep water out. We repair Chimney & Roof Junction Leaks, assessing the flashing, leadwork and surrounding roofing where water ingress is suspected around the base of the chimney.
Chimney leaks can be particularly difficult to diagnose because several exposed materials meet within the same area. A damp patch near a chimney could relate to flashing or leadwork, deteriorated mortar, damaged brickwork or a defect within the surrounding roofing.
RRB Roofing has extensive practical experience investigating and repairing chimneyrelated problems, with customer feedback specifically highlighting successful chimney and leak repairs. We explain what we find, focus on repairing the actual cause of the water ingress and provide before-and-after photographs on relevant roofing work.
Our experience with chimney, flashing and general roofing repairs allows us to investigate several potential sources of water ingress within the same area.

Find answers to common questions about leaking chimneys in Belfast, including identifying water ingress, flashing problems, deteriorated mortar and leaks that only appear during bad weather.
Water ingress around a chimney can result from problems with flashing or leadwork, deteriorated mortar or brickwork, or defects in the surrounding roofing. The area needs to be assessed to determine the actual source.
We assess the relevant chimney components and surrounding roof rather than relying only on where damp appears internally. This helps identify likely points where rainwater is penetrating before the repair is determined.
Yes. Damaged, loose or deteriorated flashing and leadwork can allow rainwater to enter where the chimney passes through the roof.
Deteriorated mortar can make the chimney more vulnerable to moisture penetration. However, because several defects can produce similar symptoms, the complete affected area should be considered before deciding what requires repair.
Wind-driven rain can reach vulnerable areas that are less exposed during normal rainfall. A leak that appears only in particular weather conditions can still indicate a defect with the chimney, flashing or surrounding roofing.
