The aim of this work is to conduct the assessment of the development of a fire on a waterproofing carpet as a result of exposure to a low-power ignition source outside the roof structure. In this article, tests were carried out according to the method of CEN/TS 1187:2013, Test 2 and Test 3 to determine the fire hazard of a roofing composition with a wooden frame and a coating, which consist of shingle «TECHNONICOL», galvanized steel profiled sheet and steel waterproofing layer with polymer coating. According to the results of the tests, the roofs with shingle are practically not inferior to similar roof structures with a coating of metal sheets in terms of fire safety. The test results showed that despite the presence of combustible materials in the composition, certain structural solutions allow to obtain class Broof (t2) (mean damaged length of the roof covering and substrate ≤0.550 m at 2 m/s wind speed) and Broof (t3) (time for external fire spread to the edge of the measuring zone TE≥ 30 min and time to fire penetration Tp≥ 30 min). However, these tests are not related to large scale reference tests.
