Which tool is commonly used to find leaks in roofing?

A thermal scanner is commonly used to find leaks in roofing because it allows inspectors to detect temperature differences on the roof surface. When there is a leak, moisture can accumulate underneath the roofing materials, affecting their thermal properties. The thermal scanner identifies these disparities, indicating potential problem areas where leaks may be occurring. This method is non-invasive and enables inspectors to pinpoint issues without damaging the roofing structure, making it an effective tool for leak detection.

In contrast, while moisture meters are useful for measuring the moisture content in materials, they require direct contact and may not always effectively indicate the precise location of a leak within a roofing system. Pressure gauges are typically used to assess the pressure within a system, which is not directly applicable to identifying leaks in roofing. Acoustic detectors can locate leaks through sound but may not be as commonly employed specifically for roofing compared to thermal imaging techniques.
