Thermal Camera

Thermal cameras detect infrared radiation emitted by objects and convert it into a visible temperature map (thermogram). In roofing applications, this technology is invaluable for non-destructive investigation. Wet areas in a roof — whether from a leak or condensation — appear as distinct cool spots on the thermal image, because the evaporative cooling effect of the moisture lowers the surface temperature. Similarly, areas of missing or compressed insulation appear as warm spots (in winter) or cool spots (in summer) compared to the surrounding well-insulated areas. Thermal imaging is particularly effective when performed under the right conditions. For leak detection, the most useful time is during the drying period after rain, when moisture-laden areas cool at a different rate than dry areas. For insulation assessment, a significant temperature differential between inside and outside (at least 10 degrees Celsius) produces the clearest results — making winter the optimal time for this type of survey in Gippsland. Town & Country Roofing utilises thermal imaging as part of detailed roof inspections, particularly when investigating elusive or intermittent leaks, assessing the extent of hidden water damage, and evaluating the effectiveness of existing insulation. The thermal images provide clear visual evidence that can be shared with homeowners, insurers, and building surveyors to support repair recommendations and insurance claims.
