Surveyor roof inspection.
The amount of time required for these antiquated methods is costly not to mention the liability risks.
Roofing contractors sell roofs.
Stored items and or lack of safe access to a roof space.

Surveyors will do their best to inspect a roof space however when there s a thick layer of insulation on the joists and timbers are not visible it s sometimes not possible to do so.
Roof inspections have historically required observation either at the ground level from a ladder or from physically walking the roof.
Most often the exterior roof will be inspected from ground level only and this is simply not adequate i am still shocked by what some of the less competent house surveyors miss to this day.
These observations not only involve steep angles but also expansive and even inaccessible areas.
