Retail facilities like shopping centers, hypermarkets and DIY stores usually have a large-area flat roof. On the premises of such buildings, thousands of customers and staff are present at the same time, and often the commercial facilities also include multi-storey car parks. The monitoring of the roof structure is crucial in this case: it gives you full knowledge about the condition of the roof, allows you to take the necessary actions and extends its life. Also regular and accurate monitoring pre-empts any possible problems and gives real time condition of the roof and associated structure. This allows you to take any necessary maintenance at the earliest opportunity. It becomes easier to unblock the roof inlets, remove snow from the roof, and carry out regular inspections. But the most important is that, our solution increases the security of people within the facility.
