Installation and Maintenance of Sheet Lead Weatherings

Installation Theory Course

Learn Plumbing Home page

This is the final Module of the Learn Plumbing Installation Theory Course. It covers the knowledge need to install and maintain sheet lead weatherings including: prepare the roof structure, fabricating and installing sheet lead weathering’s to chimneys, roof abutments, roof penetrations, valley gutters, dormers and canopies. It also covers the special health and safety requirements that must be complied with when a person works with sheet lead. Also included are explanations of the potential problems that can occur due to poor installation practice, such as wind-lift and cracking due to expansion and contraction of the lead through thermal cycling.


Once a person has successfully completed all ten Modules of the Learn Plumbing Installation Theory Course they will receive their overall Summary Record of Achievement.

By now they will also have more knowledge than is required by a Trained Plumber or Heating Installer (qualified to NVQ Level 2), and the Records of Achievement can be used as part of the Portfolio of Site Evidence to show Supplementary Knowledge.


If a person decides to follow the Plumbing New-Entrant Route and register to take the City and Guilds 6189 Certificate in Plumbing they can use the set of Revision Notes (see below) provided with the Course to quickly refresh their memory if necessary before sitting the written test papers and the GOLA computer based assessment of their theory knowledge needed for this certificate.
