The rate of corrosion of roofing sheets especially those made of galvanized sheets is very high in the Niger Delta of region Nigeria. This could be due to the high level of atmospheric pollutants emitted mainly from gas and other industrial activities. To determine the impact of atmospheric pollutants, two shades were constructed at Idu, an oil bearing community with three gas flares. The shades were installed windward to provide maximum exposure to atmospheric pollutants and the rate of corrosion monitored nine-month period. The first shade was inclined at 30o while the second was inclined at 70°. A sheet was removed from each of the shades monthly and comparison made with its original characteristics and corrosion rate noted. The rate of corrosion is the speed at which any metal in a specific environment deteriorates. The corrosion of galvanized corrugated iron sheet is the deterioration of galvanized corrugated iron sheet as a result of air pollutant reactions. Pollutants act faster in dry season than rainy season when acid rain is diluted beyond pH of 5.3 which is more than its corrosion strength. Besides at the inclination of 70° does not allow pollutants to settle on the roof and therefore corrosion is minimal.
