Today the soft roof is one of the most commonly used roofing materials. A sheet of flexible roof has a multilayer structure. Its fiberglass is based on it, saturated with bitumen. To this basis on both sides, layers with additives-polymers are adjacent. The oxidized bitumen in the composition of the material performs the main function, which is why the soft roof is characterized by such high practicality, increased wear resistance and sound permeability and amazing resistance to negative effects.
