Thermal imaging, or thermographic imaging technology, is one of the methods which roof surveyors  will use to detect any heat loss. It does this by taking thermal images of the roof, which will then show where areas of the roof are hotter than others, which indicates where the leak in the roof is.

A leak in your roof could be down to a number of reasons, with a number of potential problems arising as a result. It could simply be an issue with the insulation, and a small job can fix that for relatively little cost, but it could be a real hole which has allowed water to get into your roof structure and begin to cause real damage, resulting in thousands of pounds of costs to repair it.

So, to recap, thermal imaging can be used as means to determine the effectiveness of the heat capturing effect of your property, as well as to determine if there is any damage occurring as a result of a leak. Both of these are important tasks, but one of the things which makes thermal imaging such an attractive option is that it does this entirely through non-invasive methods.
