01
Create a simple storage record
Record the building location, storage area, approximate quantity, and the roof zones the stock may serve. Include photographs of both the material label and the storage position. Keep the record with the roof documents rather than only on the crate.
02
Maintain it when stock moves
If spares are relocated, update the record and tell the person responsible for maintenance. After repairs, record the pieces used and remaining. Ask the contractor about suitable storage arrangements for the actual material and packaging. This small administrative step can save a future search through unrelated building supplies and prevent serviceable repair stock from being discarded as anonymous leftovers.
