As well as installing leadwork to complement the traditional roof systems such as valleys, flashings, aprons etc, lead flat roofs can offer that extra performance where the need arises. Often specified on listed buildings or high specification contracts, lead roofs are installed in accordance with Lead Association guidelines, providing a traditional and exclusive finish.
Sand Cast Lead
This lead is traditionally cast by hand all as the Romans did many years ago. This is used on many ancient buildings including church work, mansion houses and many English Heritage jobs. Many ornamental features and rainwater systems were carried out in sand cast lead many years ago. We pride ourselves in carrying on this tradition. This material has also been used for the lining of coffins.
This has increasingly been used over the years, especially on building sites where much thin lead flashing is carried out (codes 3 4 and 5). It is also increasingly now used on public buildings and house extensions/bays. This material comes up to a maximum of code 8.
In most cases a cavity tray works in conjunction with a lead flashing at a roof/wall abutment. The cavity tray protects the inside of the outer leaf and the cavity and the lead flashing protects the face of the outer leaf and the junction between the roof covering and the wall.
