Fast, Professional Drone Roof Inspections
From large central London sites
to smaller
residential properties.
What we do
-
We provide professional drone roof inspections for residential, commercial, and heritage buildings across the UK and Europe.
Using high-resolution aerial imagery, we inspect pitched and flat roofs, chimneys, gutters, parapets, and hard-to-access areas safely and efficiently.Our surveys deliver clear visual evidence and concise reporting to support maintenance planning, condition assessments, insurance queries, and professional surveys—without the cost or disruption of scaffolding or access equipment.
-
We carry out thermal roof inspections using calibrated thermal imaging to help identify potential heat loss, moisture ingress, and insulation defects.
Thermal surveys are typically used on flat and complex roof structures and are carried out in suitable conditions to support maintenance planning, defect investigation, and insurance or technical reporting.
Findings are presented alongside visual imagery to provide clear context for surveyors, property managers, and building owners.
-
We support leak detection investigations by combining high-resolution drone imagery, thermal imaging (where appropriate), and visual inspection to help identify likely points of water ingress.
Surveys are used to narrow down defect locations, support further investigation, and inform maintenance or repair decisions.
All findings are presented with clear visual evidence and appropriate caveats for professional and insurance-led workflows.
-
Pre-purchase roof surveys provide an independent visual assessment of roof condition prior to property purchase. Using drone imagery and, where appropriate, internal roof-space inspection, we identify visible defects, signs of deterioration, and areas requiring further investigation.
Surveys are designed to support buyers, surveyors, and conveyancing professionals with clear visual evidence to inform decision-making—without invasive access or disruption.
-
Internal loft inspections are carried out where safe access allows, providing a visual assessment of roof structure, timbers, insulation, and signs of moisture ingress.
These inspections complement external drone surveys and help build a clearer overall understanding of roof condition for surveyors, property owners, and managing agents.
-
We support insurance inspections and claims by providing independent visual roof assessments using drone imagery and supporting photography.
Surveys document visible damage, defects, and roof condition following storm events, water ingress, or reported issues.
All findings are presented with clear visual evidence to assist insurers, loss adjusters, surveyors, and property owners during the claims and assessment process.
-
Aerial property photography provides high-resolution imagery to document buildings, sites, and surrounding context from above.
This service is used to support surveys, planning applications, marketing, reports, and general site documentation for residential, commercial, and heritage properties.
All imagery is captured safely and in accordance with UK aviation regulations, delivering clear, accurate visuals without the need for access equipment.
-
Condition and defect reports provide a clear visual record of roof condition, highlighting visible defects, deterioration, and areas requiring further attention.
Using high-resolution drone imagery and supporting photography, reports are structured to support maintenance planning, professional surveys, insurance reviews, and conservation or funding decisions. Findings are presented clearly and objectively for surveyors, property managers, and building owners.

Condition Reports & Defect Documentation
We provide clear photographic condition reports highlighting defects, deterioration, and areas requiring attention. Reports are used to support maintenance planning, surveys, pre-purchase, and funding or conservation decisions.
Our reports are designed to be clear, visual, and easy to understand.
We begin with an aerial overview image to divide the roof into clear sections.
Defects are then labelled using architectural-style references (e.g. A1, A2) and supported with high-resolution images and close-ups.
The final report provides clear visual evidence to help surveyors, contractors, and property owners understand condition and prioritise repairs.
