Life of operation
As we know, bitumen is an unusually stable chemical substance that can effectively resist even solvents and acids. In fact, an inexpensive withdrawal of oil refining, bitumen is endowed with complete immunity even to this type of chemically active substances, such as solvents and acids. Therefore, it is not surprising that flexible tiles practically do not deteriorate during operation. Among other things, bitumen tiles absolutely do not lose color. The dye is imprisoned in the structure of the material, so the color of the bitumen roof does not disappear in the sun, and also is practically not washed out of rains. Because of what, the need for periodic tinting of the roof is simply absent.
