The aerial overview immediately identified several areas of concern across the building complex, demonstrating the efficiency of drone survey technology in providing comprehensive property assessment.

The Challenge: Collect photographic data for a Roof Assessment

The property consisted of several interconnected commercial and residential buildings in Herne Hill, SE24, each presenting unique inspection challenges. Traditional scaffolding or ladder access would have required significant investment, road closures, and posed considerable health and safety risks. The client needed comprehensive images of:

  • Flat roof membrane condition
  • Moss and vegetation growth patterns
  • HVAC system integrity
  • Structural damage assessment
  • Water ingress potential areas

The Drone-Based Solution: Utilising Advanced Aerial Inspection Technology

Our certified drone pilots deployed high-resolution UAS technology to conduct a thorough aerial inspection of this property. Using a drone provided us with access to all roof levels, capturing detailed imagery that revealed critical maintenance issues invisible from ground level. We took many shots from various angles to demonstrate the condition of the roof.

This expansive shot from our Drone Survey in Herne Hill, London, illustrates the overall condition of the property’s exterior, including facades, boundaries, and roofline. RICS surveyors can utilise such views for initial assessments, identifying potential structural issues, vegetation encroachment, or general maintenance needs across the entire building envelope, providing an understanding without intrusive site access.
