Roof leaks can cause costly damage to a building’s structural integrity,it’s plant and contents. An infrared inspection can quickly pinpoint missing or moisture - laden insulation under a flat roof membrane where the insulation needs replacement, permitting the surgical repair of failed areas rather than the much more costly replacement of the entire roof. |
Roofing IR inspection is best conducted after sunset, since the wet areas retain the heat absorbed during the day longer than the surrounding dry areas, causing a temperature difference that can be imaged, with the wet areas showing up as hot spots. IR can also be used to inspect roof decks from inside a building, a highly effective approach when working with metal and ballasted roofing systems, which are difficult or impossible to inspect from above. In this case, inspection can be performed shortly after sunrise, when the wet areas of the underside of the roof warm up more slowly than dry areas and show up as cold spots. Using IR cameras, capable of recognising temperature differences down to 0.1 °C. such anomalies are easily recorded. |
