01
Begin with how the roof sheds water
Learn to identify courses, exposure, headlap, joint offset, starters and the paths that water follows around roof features. Use drawings and a ground-level sample panel to discuss those relationships. Understanding why a detail works is more useful than memorizing a dimension without its application.
02
Study the material and assembly together
Compare representative slate sizes and thicknesses, then identify the supporting deck, fasteners, underlayment and flashing. Learn to read an installation specification and locate the system-specific instructions. Practice explaining which rules belong to conventional double-lap work and which belong to a particular proprietary assembly.
03
Develop craft with supervision
Cutting, punching, sorting and replacing slate require practice and suitable equipment. Seek hands-on instruction from experienced slaters before undertaking roof work. Work-at-height training and an appropriate access plan are separate necessities; watching a video does not establish field competence.
04
Evaluate courses by outcomes
Ask what a course teaches, whether practical work is included and how competence is assessed. If you need continuing-education credit, verify the current provider and course approval directly. These public guides support learning but do not themselves award professional credit or certify an installer.
