A Guide to Roof Conservation for Listed Properties

If you own or care for a listed building, you’ll know the roof is far more than the final line of defence against the elements. Whether slate, clay tile, thatch or lead, it’s one of the building’s defining features — a protective skin that reflects centuries of craftsmanship and history. In England and Wales, being Listed gives a building legal protection because of its special architectural or historic importance. That means if you’re planning any repairs or changes that could affect its character, you’ll need Listed Building Consent.

So what does that mean when repairs are needed? How do traditional craft, modern legislation and protected species shape the decisions you can and can’t make? And what are the consequences if the rules aren’t followed? Let’s take a closer look.

How to deal with bats in the roof space

Bats are protected species under UK law – specifically the Wildlife and Countryside Act 1981 and the Conservation of Habitats and Species Regulations 2017. These protections make it an offence to deliberately kill, injure, capture, disturb or damage a bat roost, even if bats are not present at the time of work.

In practice, this means you may need an ecological survey before carrying out major roof work. If bats are present, or even suspected, you might also need mitigation measures or a European Protected Species Licence.

Skipping this step isn’t worth the risk. Failing to get the right surveys or licences can lead to prosecution, hefty fines and serious reputational damage.

At Parker & Son Construction, we work with accredited ecological consultants which ensures our projects comply with wildlife legislation and that we protect the well-being of protected species that share our historic buildings.

Roof Works & Building Control Explained

Another part of building rules that often confuses people is what happens when you strip and re-cover a roof. Under the Building Regulations – particularly Approved Document A (which covers structure) – simply re-tiling or re-slating your roof is typically considered “like-for-like” maintenance. In other words, if you’re not making any major changes to the actual roof structure you typically won’t need Building Regulations approval.

However, when more than 50 per cent of the roof is stripped back – for example, removing battens, sarking, or other coverings – the works can no longer be treated as simple maintenance. In such circumstances, the project typically needs to be notified to Building Control. This ensures that the roof meets modern standards for weatherproofing, load-bearing performance and thermal performance.

Unfortunately, some builders either misunderstand these rules or choose to ignore them. A few will carry on without notifying Building Control, seeing it as unnecessary red tape. It might help them keep their prices low in the short term, but cutting corners like that can put both the homeowner and the contractor at real risk.

Who Is Responsible for Non-Compliance?

If roof work isn’t properly registered and it breaks Building Regulations, both the homeowner and the contractor can be liable. Building Control can issue enforcement notices, meaning the work has to be fixed or even removed.

A lot of people assume only the tradesperson gets fined. That’s not always the case. Enforcement can apply to anyone with an interest in the property. So even if a homeowner relied on a contractor’s word, they can still be held responsible if the right notifications weren’t made. On the flip side, contractors who ignore the rules or mislead clients can face fines, enforcement action and even restrictions on future work.

Parker & Son Construction operates under a recognised self-certification scheme for roofing works. This means we can notify Building Control through an approved body, making the process smoother for our clients while ensuring everything is fully compliant. We take responsibility for meeting the relevant Building Regulations and provide the proper certification once the job’s done.

Working on a Listed Building roof isn’t just about practical skill. It’s about understanding heritage rules, wildlife protection and staying on the right side of the law.

At Parker & Son Construction, we blend traditional roofing know-how with a solid understanding of the regulations. From checking for bat roosts before starting work, to advising when Building Control needs to be notified and carrying out self-certified work that meets both heritage and safety standards – we make sure everything is handled properly.

When it comes to preserving the crown of your historic property, careful planning – and the right partner – make all the difference.
