Chimney Repairs

Safe, secure & weatherproof chimneys

Most chimney leaks we see come from two places: lead flashing that has cracked or lifted where the stack meets the roof, and pointing that has worn away and lets rain into the brickwork.

We replace flashing and lead saddles, repoint stacks and repair the tiles and slates around them so the water stays outside. Helen in Maidstone had paid another company £3,000 for new lead and tiles before we traced and fixed the real leak; her review is below.

What your neighbours have to say

Helen P. Maidstone

January 2026

“We were told a leak was coming from our chimney and paid £3,000 for new lead and replacement tiles. Less than two days later, the leak returned. The problem had not been solved at all.

Josh and the team at JAG Roofing came out quickly and fixed the issue correctly. Because of the poor state the roof was left in, the repair took longer than expected, but they kept us informed throughout and were genuinely lovely to deal with.

We are incredibly grateful to JAG Roofing for finally resolving the problem and would not hesitate to recommend them.”

“We had water coming through the ceiling after heavy rain so we called JAG Roofing to take a look. Josh came out quickly, found where it was coming from, and showed us the issue. The repair was sorted, everything was left tidy, and the leak hasn’t come back since. Happy with the work.”
