In short

DG Roofing Services repoints chimney stacks, re-flaunches pots, fits cowls and bird guards, and replaces lead flashings, soakers, valleys and bay tops. Failed flashing and mortar around chimneys are among the most common causes of roof leaks.

Chimneys & Leadwork in Darlington & the North East

Chimneys and lead flashings are some of the most common sources of roof leaks. Weathered mortar, cracked flaunching and lifted or split lead let water track down inside your walls and ceilings — often a long way from where it actually gets in.

We repoint and repair chimney stacks, re-flaunch chimney pots, fit cowls and bird guards, and replace lead flashings, soakers and valleys.

All leadwork is properly dressed and fixed to suit the job, so it stays watertight for years to come.

Excellent roofer highly recommended

“We had water getting into our extension and noticed our ridge tiles were loose too. D G Roofing came out, knew exactly what the problem was straight away, and gave us a really reasonable quote. They were back just a couple of days later to get started, and even fixed a couple of small things they spotted along the way — all within the original price. Absolutely delighted with the work; I'd have no hesitation in recommending them!”

Questions

Frequently Asked

Can't see your question? Call Daz — he's happy to give honest advice, even if you're not ready for a quote.

How do I know if my chimney is leaking?

Damp patches on chimney breasts, stains on ceilings near the stack or water in the loft around the chimney are all common signs. We can inspect and find the cause.

What is flaunching?

Flaunching is the mortar collar on top of the chimney stack that holds the pots in place and sheds water. When it cracks, water gets into the stack.

Can you remove an unused chimney?

Yes. We can take down and cap unused chimney stacks — get in touch and we'll advise on the options.
