No. Galvanic corrosion (sometimes called rust) occurs when two dissimilar metals are brought into contact in the presence of an electrolyte (moisture). Simply put, when a snow stop made of a certain type of metal is placed on a roof made of a different type of metal and is exposed to snow, rain, and ice, they begin to corrode. This process is called galvanic corrosion and is the cause of the staining and streaking of the roof.

Color Armor™ prevents the problem of streaking and staining in a simple yet effective way. Because the Color Armor™ is placed over a polycarbonate base, the metal from the snow stop and the roof never come into contact with each other. The polycarbonate base is the only material that actually touches the roof, and polycarbonate does not cause the corrosion of metal. Color Armor is usually made out of the same material as the roof anyway, which would also prevent any galvanic reaction from occurring even if the snow guard and the roof did come into contact.
