Often, residents of single -family private houses are faced with the problem of plaque on roofing roof elements. Such trotes are a consequence of the interaction of the atmosphere with products that can give oxide. In practice, the spots appear if metal objects are placed on the roof, such as stairs or other structural elements, which, when interacting with water, give oxidation.
To get rid of such pollution, it is necessary to remove all metal reagents from the roof or replace them with non -metal or those that are covered with a thick layer of protective coating. Do not run the process of the appearance of the fluxes, since over time it will only intensify. Sometimes white or gray spots appear on the roof. Before proceeding to their removal, you should pay attention to the places of their accumulation and the appearance.

Such a problem must be fought comprehensively, with the replacement of the entire layer of plaster or finishing, in some cases it is necessary to shift the chimney.
