Roof and façade inspection without scaffolding or an aerial lift

A drone is the right instrument when you want to know where the problem is. When someone has to touch it, it no longer is.

Choose scaffolding or an aerial lift when the inspection coincides with the repair, when a material sample has to be taken, when something has to be tapped, probed or opened up, or when an expert has to make the assessment on the roof itself. Interiors, crawl spaces and fully covered structures are also outside what we do.

Choose a drone when you first want to know where you need to be, when the surface is large and the damage unknown, when you want to compare the condition year on year, or when putting up a scaffold is a project in itself. In practice the drone comes first, followed by targeted access to that one zone.

HOVVR holds an operational authorisation from the Belgian Civil Aviation Authority (BCAA) in the Specific category, based on a SORA risk assessment. Within the conditions of that authorisation we also work in urban environments and near uninvolved persons, where a flight in the Open category is not permitted. Flight preparation and the necessary permissions are included in your quote.

A thermal capture shows temperature differences at the surface. That is not the same as moisture, and not the same as a leak. The difference only becomes meaningful when the temperature difference between inside and outside is large enough, when the surface has not just been warmed by the sun or cooled by rain, and when the material can be measured. Glass, bare metal and wet surfaces are hard to read.

A drone is strong on large or hard-to-reach surfaces: you see a complete roof plane in one capture and can compare zones with each other. A handheld camera is stronger indoors, for detailed work at eye level and when the thermographer wants to verify on site straight away.

We always deliver thermal images together with visual images of the same zone, never as a stand-alone conclusion. The radiometric files are included, so your thermographer or building surveyor can carry out their own analysis. The interpretation stays with them.

A contractor needs different information from an insurer, a building manager (syndic) or a technical property manager. That is why we organise the images by zone, name locations in plain language and deliver only the formats you will actually open.

We document what is visible or measurable and mark zones that deviate. The structural, insurance or thermographic interpretation stays with the qualified specialist. That separation makes the dossier stronger: you know exactly what comes directly from the images, what is an indication and where further investigation is still needed.
