A visual pest-entry survey can document accessible openings, displaced materials, ledges, fouling and observed activity. It cannot see through coverings, certify structural condition or prove that every concealed route has been found.
Define the coverage before attendance
Divide the roof into named slopes, elevations, parapets, valleys, gutters, plant areas and adjoining boundaries. Mark the internal rooms or voids where signs were reported. The survey brief should identify the decision: locate a possible route, plan wildlife-safe closure, or decide whether another specialist is needed.
Agree the view method for each zone. Ground observation, pole camera, direct access, platform and drone each reveal different detail. If a drone is proposed, the operator must assess current CAA requirements for the aircraft, people, airspace, visibility, privacy, permissions and weather.
Ask for overview photographs before close-ups, location labels and a map showing viewed, partly viewed and unseen areas. A sharp image of a lifted edge is not actionable when nobody knows which roof slope it belongs to.
Separate pest observations from roof diagnosis
The report can say that an opening aligns with observed animal movement or nearby material. It should not call a tile structurally sound, diagnose water ingress or certify insurance condition. Cracks, movement, corrosion and staining need referral to a roofer, surveyor or engineer.
For example, a gap beneath flashing and nesting material nearby may justify a pest or wildlife assessment and a building referral. It does not prove the animal caused the defect or that the gap is the only route.
State weather, lighting, vegetation, plant screens and inaccessible loft areas as limits. If a second inspection method is recommended, explain the question it would answer.

FAQs
Does a photo prove a gap is active?
No. It documents visible geometry; activity needs its own evidence.
Can a visual survey clear the entire roof?
No. The report should name concealed, inaccessible and partly viewed areas.
Is a pest survey a structural survey?
No. Building condition requires the appropriate professional scope.
