The Roof Restoration Project

We have embarked on our most ambitious restoration project to date, the major repair of the roof of the UNESCO World Heritage Site.

This monumental £12 million project is preserving Britain’s Greatest Palace, protecting its historic architecture and safeguarding its heritage for generations to come. The last couple of months have been incredibly busy as we head towards the completion of this project. For the first time in almost two years, parts of the Palace are beginning to emerge from behind the scaffolding.

Artwork like the eyes above the entrance can be seen again, as the North side of the scaffolding begins to come down. 'Last restored in 2008, they’ve now been cleaned, stabilised and refreshed - removing dirt, cobwebs and flaking paint, and restoring the gilding and colour so the painting reads clearly once more.'

Join us for hands on heritage experiences

Explore the Heritage Learning Lab. Here, you will discover the different techniques that underpin our restoration work and how the site of Blenheim Palace was built over 200 years.

Whether you’re a history enthusiast, a budding craftsman, or simply curious about the intricate work that goes into restoration, the lab is full of fascinating information. 

Get stuck in and see the restoration in action with demonstration days taking place throughout the last few months. These will reveal the vital processes of stonemasonry, joinery and gilding that have preserved the Palace for centuries.

Why is it important?

At the start of the project Kelly Whitton,  our Head of Built Heritage commented... “This is a crucial undertaking that we must deliver if we are to secure the future of wall and ceiling paintings of international importance, whilst also protecting the Palace from further damage. We're not just maintaining a structure; we're safeguarding a legacy.”

The objectives of this project are multifaceted, each crucial for preserving the essence of Blenheim Palace.

  • Improve environmental stability of two internationally important ceiling paintings
  • Reduce health and safety risks from stone fall
  • Prolong the lifespan of stone by slowing the rate of decay
  • Complete outstanding fire compartmenting works in roof voids
  • Increase capacity of roof gutters to reduce further risk of water ingress
  • Improve energy efficiency where possible and practical

What are the challenges?

A combination of age, (Blenheim Palace is over 300 years old), climate change and penetration from rainfall have led to the declining state of the roof, attic timbers and ceilings below.

The area of the roof in question - almost an acre in size - is only served by six downpipes; excess rains mean leaks are commonplace.

The Great Hall ceiling painting by Sir James Thornhill, describes the 1st Duke of Marlborough kneeling to Britannia, proffering a plan of his victory at Blenheim. This painting, already suffering from hairline cracks over much of the surface from structural movement, now has substantial rainwater damage and mould growth.

In the Saloon, roof leaks, smoke damage and dirt have also caused significant damage to the painting of the Battle of Blenheim by Louis Laguerre, where Peace is depicted physically restraining the Duke.

How has this happened?

Over its 300-year history, the Palace has weathered many storms, but the toll of time and environmental factors now necessitates urgent action.

Blenheim Palace first opened to the public in 1950 in order to fund extensive spot repairs to the central roof areas; primarily above the Great Hall and Saloon. These repairs are now at the end of their life.

Roofs are notoriously expensive to replace, notwithstanding access issues, the scale of Blenheim Palace and the impact to our visitors meaning that this project has been developed over a seven-year period.

How much is it costing?

£12 million, with two-thirds privately funded by Blenheim Palace, however this exceeds our resources. 

We are therefore seeking further support from a variety of trusts, foundations and individuals to bridge the current funding gap.
