For chimney repairs in Knocklyon, Peak Roofing provides expert, fully insured service. Crumbling chimney mortar, failed lead flashing and cracked chimney pots are among the most common causes of roof leaks in Knocklyon. Our roofing specialists carry out everything from minor repointing to full stack rebuilds across Knocklyon — deteriorated pointing allows water to penetrate the stack, while failed lead creates a direct leak path into the roof. We diagnose and repair all chimney issues on a single visit, with a free inspection and written quote before any work begins.

Knocklyon is a well-established south-west Dublin suburb built predominantly in the 1980s, with a close-knit community feel and a range of residential estates on elevated ground between Rathfarnham and the M50. Properties in Knocklyon are predominantly 1980s semi-detached and detached estate houses, some 1990s townhouse developments, and a small number of bungalows on the higher roads. Common roof issues we address here include concrete tile deterioration and ridge tile repointing on 1980s stock, felt underlay deterioration on properties now exceeding 40 years, flat roofs failing on garage and extension roofs, and fascia and soffit replacement, meaning chimney maintenance is particularly important for Knocklyon homeowners. Our roofers understand the construction methods and typical materials used in Knocklyon — every inspection is free and every job begins with a written quote.

"James and the team have done two different jobs for us. The first was to re-felt our roof and fix the flashing around the chimney and clear gutters which cleared up 2 substantial leaks that had been causing damage. He kept us updated with videos of the work throughout the day to show work complete and progress."

Frequently Asked Questions

From €750 — most jobs completed in 1 day. Free inspection and written quote always provided before work begins. Note: Lead flashing replacement is a separate job — typically €500–€1,200, always quoted separately after inspection.
Chimney repointing replaces the mortar between the brickwork of the stack. Lead flashing replacement removes and relays the lead where the chimney meets the roof surface. These are separate jobs, always quoted and invoiced separately. Repointing does not include lead work unless explicitly stated in the written quote.
Common signs include visible gaps or crumbling mortar between the bricks, water stains on ceilings near the chimney breast, loose or missing chimney pots, and mortar debris in the gutters below. A free inspection is the most reliable way to assess the condition of your chimney stack — we cover all of Knocklyon with no call-out charge.
Most chimney repointing jobs in Knocklyon are completed in 1 day. Larger stacks or those requiring scaffolding may take slightly longer. We always confirm the expected duration in our written quote before any work begins.
Yes. We supply and fit replacement chimney pots, anti-downdraft cowls and bird guards across Knocklyon. Chimney pot replacement is typically included within the repointing quote where pots are loose or cracked.
In Knocklyon, the roofing problems we see most often are concrete tile deterioration and ridge tile repointing on 1980s stock, felt underlay deterioration on properties now exceeding 40 years, flat roofs failing on garage and extension roofs, and fascia and soffit replacement. A free inspection is the best way to check whether any of these apply to your roof — call 085 782 8222 to arrange one.
