I need to carry out yearly maintenance on a roof solar water heater. I only have roof access on a servitude basis and don't feel comfortable going up due to a tall ladder with no guardrails hatch system being in place.

If I hire a technician from a company to do it, will they manage on their own, or expect me to tag along? Can I say I don't feel comfortable with heights and the access situation and let them handle it?

Thank you in advance.
