If you have a top of the line Colorbond® steel roof protect your investment. Your choice of roofing and location are very important. Environment is a major factor in metal maintenance. A coastal area, with its salt wind, may cause major surface deterioration. In contrast, in a drier, non-coastal rural area roofing may last for decades with little or no maintenance.
Other incompatible environments include around swimming pools, and organic materials. In some cases, windborne materials landing on the roof like tree branches may rot and release water which can damage your roof. Be sure to check your roof with a visual inspection after storms for debris.
