An access log records who visited the roof, why, and where work occurred. It does not prove responsibility for damage, but it helps reconstruct changes when problems arise. This is useful where multiple equipment contractors share access.
What to do next
Require visitors to identify their work area and report roof alterations. Keep relevant photographs and service orders together. Ask the roof contractor how to coordinate penetrations and repairs so equipment maintenance does not become an undocumented roofing modification.
