In partnership with T & P Lead Roofing Ltd, we recently completed an ornamental lead facade utilising new and traditional methods of construction.
The works involved all varieties of skills, lead bossing, lead casting, lead welding, carpentry and design
Slate is a natural stone, tiles are manufactured. A ‘slate tile’ is a piece of slate measured, cut and prepared for use as a tile. Slate is a fine-grained metamorphic rock that can be split easily into thin layers; it’s mainly grey in colour, with a wide variety of textures, colour varieties and irregular patterns.
Tiles are made from a variety of hard-wearing materials, usually fired clay and concrete.
They are used for covering surfaces such as roofs, walls and floors, Clay tiles are capable of performing down to pitches as low as 15° (depending on the type of clay tile) whereas slates can only perform down to 25°
This is a photo of a lead hopper restoration we carried out for the Serpentine Sacklers Gallery in London’s Kensington Gardens.
The grade 2 listed building, originally known as The Magazine, was built in 1805 in the style of a Palladian villa and used as a gunpowder depot for the army in the event of a 'foreign invasion or popular uprising', but has not housed munitions for the last 50 years. It occupies a prominent position on West Carriage Drive, running from Exhibition Road to Bayswater Road.
The hopper heads on the building were extremely fragile due to their age which, although not verified, possibly date from the reign of King George III as the insignia and date suggest.
For this restoration we had to firstly remove the several layers of paint that had been added over the decades. The main body of the hopper had to then be delicately removed from the back plate as the lead backing had deteriorated beyond a restorable condition. The body of the hopper then needed to be carefully dress back to its original form and strengthened before a new back plate could be attached.
