Abstract—The research work is predicated on the challenge posed by recent innovations on the varieties of roofing sheet materials from which a sizeable number of the population conventionally obtain their drinking water in form of roofing sheet intercepted rain water. The rain water samples were collected from three different roofing sheet types and ‘ages’ at Dada Estate in Osogbo, Osun State. The different roofing sheets evaluated were iron zinc, Aluminum, asbestos (Adex). The samples were collected and analyzed using standard methods with adequate quality control measures. The ranges of values of the investigated parameters were; pH (6.545-7.20), Hardness (0.250-3.775mg/l), TDS (0.004-0.023mg/l), TSS (0.580-0.740mg/l), Alkalinity (0.01-0.28mg/l) and T.S (0.586-0.763mgmg/l). The heavy metals determined include lead and chromium ranging from (0.036mg/l-0.184mg/l) and (0.049mg/l-0.393mg/l) respectively while cadmium was not detected in any of the roofing sheets type and ‘age’ examined. It was concluded from the findings, that rain water from any of the above intercepted roofing sheet should not be regarded as potable water hence, periodical analysis and treatment of rain water is recommended.
