S&J re-roofed our 1960’s house during September. The service was excellent from start to finish. Everyone we dealt with at S&J was polite, courteous and helpful. We chose them because they were a long established local family business with a good track record offered a 25yr guarantee and they had done a good job on a neighbour house . On our house they removed the existing tiles, battons very damaged felt liner. They installed a new breathable lining, new battons and we opted for new tiles.. we are very pleased with the outcome. Thanks to Lee, Naomi, Tom, James, Kye, Scott, Cam and Jay…. You made it a painless experience

If it were possible to give a higher than 5* review, I would be more than happy to do so. Prior to instructing a company to do my roof renewals, I obtained five quotes. These quotes were from reputable Bath specialist roofing companies, all with a minimum of 4.6 plus reviews. S&J Roofing were the last company I met with, by this time I had already instructed another company. I was so impressed after meeting with the Director of S&J, Lee Shellard, that I cancelled the other company I’d already instructed (forgoing my deposit.) Before starting the work Lee encouraged me to come into the Walcot Street shop, so I could see all the materials that would be used on my roof and check I was happy before the work commenced. Throughout the project I could not have been happier with how the work was carried out. The S&J team were, polite, tidy on site, worked extremely hard even in the summer heatwave. They were always happy to answer questions and kept in constant communication regarding the work that had been done and completion timings. They completed the work on time and left the site immaculately tidy. I’m so grateful that I decided to instruct S&J and would not hesitate to recommend them. They are absolute professionals and a brilliant example of a specialist family-run company, who really care about the work they do and how they conduct their business. My sincerest thanks, to all the S&J team.

⭐⭐⭐⭐⭐ S&J Roofing Bath recently carried out work on my property and I couldn’t be happier with the result. The workmanship was exceptional, and the communication was excellent from the moment I first made an enquiry right through to the finished project. Everything was handled professionally, the work was completed to a very high standard, and I was kept informed throughout the whole process. Highly recommend!

What an amazing experience dealing with Lee and his team at S&J Roofing in Bath. Not only were they responsive from the first contact but kept me in the loop on every aspect of the tricky historical roof. Which they repaired, with like for like materials and even went above and beyond by going to a reclamation yard to get historical coping stones that had been broken by the previous roofers. My new neighbours have all commented on how professional his team were and have all told me they filed away S&J’s contact details, As they wouldn’t think of using any other roofing company in Bath. Their work is simply superb And I wouldn’t hesitate to highly recommend them to anybody. Thank you, Lee and the team. ❤️

Chimney Stack FAQs

What is a Chimney Stack?

A chimney stack is the visible part of a chimney that extends above the roofline. It helps safely direct smoke, gases, and ventilation from fireplaces, stoves, or boilers away from the property. Chimney stacks are commonly built from brick, stone, or concrete and require regular maintenance to remain safe and weatherproof.

How To Repair a Chimney Stack?

Chimney stack repairs vary depending on the damage, but can include:

  • Repointing damaged brickwork
  • Replacing cracked lead flashing
  • Repairing chimney crowns
  • Replacing damaged pots or cowls
  • Rebuilding unstable sections

S&J Roofing Bath provides professional chimney stack repairs across Bath, helping prevent leaks and structural damage.

How to remove chimney stack?

Removing a chimney stack involves carefully dismantling the structure above roof level while ensuring the remaining chimney breast is properly supported. Because chimney stacks are structural features, removal should always be carried out by experienced professionals to ensure safety and compliance with building regulations.

How to support a chimney stack?

Chimney stacks are typically supported using steel gallows brackets, structural beams or reinforced masonry support systems.

The correct support method depends on the property type and whether part of the chimney breast remains inside the building. A structural assessment is usually required before work begins.

What are the signs a chimney stack needs repair?

Common signs of chimney stack damage include:

  • Cracked or loose brickwork
  • Leaning chimney stacks
  • Damp patches near the chimney breast
  • Damaged flashing
  • Falling mortar or debris

If left untreated, chimney damage can lead to leaks and structural issues. If you suspect damage, get in touch today for a quote and expert advice.

Can a damaged chimney stack cause roof leaks?

Yes, damaged flashing, cracked masonry, or deteriorated mortar around a chimney stack can allow water to enter the roof structure. Chimney-related leaks are one of the most common roofing problems in older properties.

How often should chimney stacks be inspected?

Chimney stacks should ideally be inspected at least once a year, particularly after severe weather. Regular inspections help identify minor issues before they become expensive structural repairs.

What is chimney repointing?

Chimney repointing involves removing damaged mortar from between bricks and replacing it with new mortar. This helps strengthen the chimney stack, improve weather resistance, and prevent water ingress.

Can a leaning chimney stack be repaired?

Yes in some cases, leaning chimney stacks can be stabilised and repaired. More severe structural movement may require partial rebuilding or removal. S&J Bath can assess the condition of your chimney and recommend the safest solution.

What causes chimney stack damage?

Common causes of chimney stack damage include:

  • Exposure to harsh weather
  • Frost damage
  • Age-related deterioration
  • Failing mortar joints
  • Poor ventilation and moisture build-up

Older chimney stacks are particularly vulnerable if maintenance has been neglected.

Do unused chimney stacks still need maintenance?

    Yes, even unused chimney stacks can deteriorate over time. Rainwater penetration, loose masonry, and damaged flashing can all affect the roof and internal structure if maintenance is ignored.

    Can chimney flashing be repaired?

      Yes, damaged lead flashing around chimney stacks can often be repaired or replaced without rebuilding the entire chimney. Proper flashing repairs help prevent leaks and protect the surrounding roof structure.
