Drone Roof Inspection

Our Client, an estates manager for Legal and General Modular Homes, had issues with multiple roof leaks across the entire roof that protects £60 million worth of factory machinery. No edge protection made a physical survey cost prohibited for a 40,000m2 roof so the client opted for a thermal drone survey.

The building was heated to 18oC with an ambient external temp of 3oC.This allows us to analyse for transient heat loss through weak joints and detailing. If heat can escape, water may easily enter the building through the same anomaly.

The client only provided the roof leak plan after the survey and we matched all known anomalies perfectly with the plan but also found many more for future referencing.

Why do we use a Thermal Drone?

Put simply, is shows us what the naked eye can’t see.
Using our state of the art, thermal imaging UAV drones we can offer an entirely new and unique perspective. We can get closer, are more manoeuvrable and go where traditional aircraft can’t.
Our visual and thermal survey was completed, safely and accurately, in a single day meaning minimal disruption to the client and the operation of the site.

Upon thermographic analysis of the roof, a general good standard of temperature consistency was discovered indicating the majority of the roof is well insulated and is in a sound condition. However, some areas of suspect inconsistent temperatures were discovered. These suspect areas were mainly located at roof junctions where the two previously separate buildings have been connected as one. Increased temperatures seen extending along these locations indicates higher than expected heat loss, in our opinion, most likely a result poor roof detailing. Regions of excessive heat loss via poor detailing are also potential sources of moisture ingress via the same pathways.
Further, regions of higher than expected temperatures were also discovered at perimeter detailing and various other locations; these have been included in the report and marked on the following roof plan for consideration; however, the majority of these anomalies are, in our opinion, minor.

About Visual Perspectives

In 2009 VP entered into Thermal imaging inspection services. In 2015 we introduced our Unmanned Aerial Vehicle (UAV), drone inspection and drone survey providing cost effective solutions to Building Surveyors, NHS, Construction, Portfolio Management, Universities and Education. We’re renowned for our professionalism and dedication to improving safety, mitigating risk, improving operations and reducing operating costs for our clients through the use of new technology and extensive building inspection experience.
