What you will see

  • A roof drain that cannot be reached without crossing panels.
  • Equipment placed across an established access route.
  • A proposed cleaning method that requires standing on modules.
  • Rooflights or fragile sheets close to the only available path.
  • Difficulty reaching equipment for a planned service visit.
  • These issues are easier to resolve during layout design, but an existing installation can also be reviewed.

Why it happens

Commercial rooftop PV planning should account for maintenance access and coordination with other roof functions. The layout needs to support future work, not only the original installation activity.

Roof access itself requires assessment. HSE identifies hazards from fragile materials, including rooflights and some roof sheets, and advises competent assessment rather than assuming that a surface will support a person.

The work method must address access and fall risks for the particular task. A ladder or a harness by itself does not establish that the planned roof work is safe.

The solar installer, building owner and relevant roof specialists should agree how routine maintenance and foreseeable repairs will be carried out. An unresolved access problem should be recorded and addressed before someone improvises a route.

Plan the route before the work

Unplanned

Crossing panels, fragile sheets, rooflights.

Planned

Agreed paths to drains, inverters and cleaning areas.

A ladder or harness alone does not make a roof task safe.

HSE identifies fragile roof hazards. Applies to arrays with LONGi, Jinko and other panels.

What you can check yourself

  • Review the layout and maintenance plan already provided.
  • Identify drains, rooflights and other equipment on existing drawings.
  • Ask how each routine service location will be reached.
  • Mention access difficulties reported by previous contractors.
  • Record later building changes that may obstruct an agreed route.
  • These checks can begin from plans and existing photographs; they do not require a personal roof inspection.

What not to do

  • Do not walk on panels, cross unassessed roof sheets or improvise a bridge between supports. Do not move modules to create a temporary path. Avoid approving work based only on the presence of a ladder or personal protective equipment.

When to call us

  • Request an access review when maintenance requires crossing panels, approaching fragile surfaces or using a route that was never assessed for the task.
