What Is a Drone Roof Survey?
A drone roof survey uses unmanned aerial vehicles equipped with high-resolution cameras and thermal sensors to capture detailed imagery of your roof surface. This data reveals defects, damage, and deterioration that are invisible from ground level and dangerous to assess with ladder or scaffold access.
Singapore's equatorial climate subjects roofs to intense UV radiation, heavy tropical rainfall, and high humidity year-round. These conditions accelerate weathering of waterproof membranes, cause ponding in flat roof areas, and promote algae and moss growth on tiles. Regular drone surveys detect these issues early, preventing costly water ingress damage to the building interior.
Our drone roof surveys serve property managers, building owners, MCSTs, and facility management companies across Singapore — from HDB estate rooftops to industrial buildings in Tuas and Jurong, to CBD commercial towers and heritage shophouses in Chinatown and Kampong Glam.
Drone Roof Survey Process
Site Assessment
We review building location, roof type, and access requirements. For buildings in CAAS-controlled airspace, we arrange flight permits in advance.
Aerial Data Capture
Our drones fly systematic grid patterns over the roof, capturing overlapping high-resolution photographs and thermal imagery. We cover every square metre including parapets, gutters, and rooftop equipment surrounds.
Orthomosaic and Thermal Mapping
Images are processed into a single high-resolution orthomosaic map and a thermal overlay. This allows precise measurement and pinpointing of every defect with GPS coordinates.
Condition Report
A detailed report documents all findings — membrane condition, drainage performance, flashing integrity, and equipment surrounds. Defects are classified by severity with recommended actions and estimated repair costs.
What Our Roof Survey Detects
Membrane Deterioration
Cracking, blistering, and UV degradation of waterproof membranes detected through high-resolution close-up imagery.
Ponding Water
Standing water areas identified through visual inspection and thermal contrast mapping, indicating drainage slope deficiencies.
Flashing Failures
Lifted, corroded, or separated flashing at parapet walls, penetrations, and equipment bases — common water ingress points.
Hidden Moisture
Thermal imaging detects moisture trapped beneath membrane surfaces — invisible to the naked eye but a precursor to major leaks.
