Our Approach to Roofline Work
We start with a detailed survey of your chimney stack, flue terminal and roofline to identify downdraughts, water ingress points, weak mortar joints or flashing failures. We work cleanly and safely, protecting your roof and property, and we explain the solution before any work begins.
Minor Repointing & Repairs
In many cases, chimney issues are related to worn mortar joints or small cracks in the masonry. Our team can carry out local repointing and minor repairs that improve both structural integrity and flue performance — often without the need for major scaffolding.
Lead Flashing & Weatherproofing
Water ingress around chimney flashing is a common issue that can affect internal flues, linings and fireplaces. We inspect lead flashing and repair or replace damaged materials to keep your chimney dry and performing efficiently in all seasons.
