Thermal Imaging Flat Roof Inspections











So…We are sure you are asking: what’s the big deal with drones? The big deal has to do with PERSPECTIVE.

First, you want to view the whole roof. There are a couple of reasons for this. One is that by looking at the overall mass, it is much easier to discern temperature differentials. Another is that if you are surveying a large roof, and were to plot out a system of discrete samples based on fixed distances between the sample points, it is entirely possible that you could completely miss the anomaly simply because of it’s shape and the need for your sample to cover a large area. If you evaluate the whole roof, this risk does not exist.

Second, is the fact that the most effective way to utilize infrared radiography tools is to reduce the angle of incidence between the images and the roof surface. this means to become as close to perpendicular to the roof surface as possible. Historically, the way this was accomplished was by using a helicopter or fixed wing aircraft, an adjoining higher building or the use of ladders and/or aerial lifts to elevate above the roof surface. As you can imagine, this introduces a number of expenses and risks.
The expenses are self-evident. The risks are increased and must comply with OSHA 1926.503 for fall hazard. Aerial lifts falls under OSHA 1926.453. Helicopters under 1926.551.

Third, the use of a drone is non-destructive and non-invasive. They are small, ultra lightweight and are piloted by remote control. They are quiet and safe. Their service is inexpensive and most importantly, they are MORE ACCURATE!

Granted, a walk-on (interactive) inspection may well be necessary, to allow thermographers to perform verification testing and mark the boundaries of thermal anomalies directly on the roof. But, they will know where to go and where to look!
