Rolled Lead Sheet, The Complete Manual.
The Lead Sheet Association
The Lead Sheet Association produces this manual about the design and installation of rolled lead to various building elements, covering everything from roofs and chimneys, to cornices, gutters, and lead sheet cladding. Lead workers, Architects, Building Surveyors, inspectors, and contractors alike may find this useful. The draftsmanship to the 3D, coloured, technical drawings within the manual are excellent. It also references BS EN 12588:2006, the malleability, fatigue, and creep resistance, for the various thicknesses (code no.) required for the lead when used in different locations, and considering the anticipated life of the building.
This is a 2015 edition, but I am sure there have been updates. This is their website:
