01
Use common fields
For each building, record roof zones, known slate selections, inspection dates, repair history, and the location of spares. Note whether material identification is documented or only provisional. A shared format makes records easier to compare without implying that every slate roof has the same age or maintenance needs.
02
Keep recommendations building-specific
Do not assign the same work solely because two roofs look similar. Attach each assessment and its limitations to the relevant building. Use the register to plan investigations and coordinate access opportunities, then update it after completed work. The register should help staff find evidence, not replace the professional judgment needed to assess individual roofs.
