Drone-Based Building and Roof Surveys

Thermal and visual drone inspections for leak detection, condition reporting and planned maintenance.

How We Can Help
 

We survey building envelopes and roofs quickly and safely using high resolution visual imaging and thermography. This is ideal for locating leaks, heat loss, failed membranes, blocked gutters and general condition issues without scaffolding or roof access. We also provide visual only options where thermal is not required.

Why This Approach Works

 

Ground checks and spot repairs often miss the wider picture. Complex rooflines, tall façades and restricted access make traditional methods slow and expensive. Aerial imaging captures complete coverage in one visit so you can see defects in context and plan targeted works with confidence.

Cut Time, Cut Costs, See More

 

One flight delivers roof and façade visuals, thermal comparisons and accurate measurements. No scaffolding, no roof walking and minimal disruption to the site. You get clear evidence for maintenance decisions, warranty claims and budgets.

​

Survey Deliverables

​

  • Side by side thermal and visual imagery of roofs and façades

  • Annotated defect map with priorities and recommended actions

  • Orthomosaic roof plan with dimensions and drainage fall context

  • Gutter, outlet and rooflight condition record with debris mapping

  • Moisture and heat loss indicators for membranes and insulation

  • 3D roof model or elevation photogrammetry where required

  • PDF summary report plus image sets and optional GIS files

 

What We Look For

​

  • Ponding, blisters, open laps and membrane failure

  • Cracked tiles, missing slates and damaged flashings

  • Blocked gutters, failed outlets and vegetation growth

  • Parapet, coping and upstand defects

  • Heat loss, cold bridging and insulation gaps

  • Cladding, pointing, render and sealant issues

 

Where This Works Best

​

Housing blocks and estates, schools and universities, hospitals and care facilities, industrial units and warehouses, retail parks, offices and heritage sites.

 

Safety and Compliance

​

All flights are planned with task specific RAMS and CAA compliant procedures. We maintain safe stand off distances, coordinate with site teams and operate outside of live works wherever possible.
