The method involves testing presence of liquid water in direct proximity to a vapor trap (5) of a roof (1) at two positions of a roof to be tested by sensors (11). The presence of liquid water above and/or outside the vapor trap is tested at a region of a heat insulation layer (7). The roof is closed based on result of testing the presence of the water, where the sensors are distributed over a surface of the roof. The positions are arranged over a roof surface in a distributed manner, where the sensors are arranged on the heat insulation layer. An independent claim is also included for an arrangement for performing a method for testing a roof. |
