Finding a leak is no easy task. New, non-invasive technologies can find the source of even the smallest problems. Some of the cost-effective solutions we use are:
Thermal Imaging – Fast and non-invasive thermal scans are used to locate wet insulation, which is a telltale sign of a failing roof system. It also reduces a building’s energy efficiency. Obtaining accurate infrared images is limited by the surface’s ability to emit heat energy.
Electronic Scanning – This method uses high voltage but low amperage. One electrical lead is connected to the roof decking, and the other is attached to a measuring device resembling a push broom that is “swept” across the roof’s surface. Any moisture or breach in the membrane will complete the circuit between the measuring device and the roof deck.
Electric Field Mapping – Developed in the early 1990s, electric field mapping uses lower voltages and is unique in its ability to test the integrity of waterproofing membranes with overburden or ballast. This testing method can be used on vertical, sloped, or flat surfaces, as well as green roofing systems, locating leaks and breaches with pinpoint accuracy.
