A recently released two-year breakthrough study estimates the annual direct cost of corrosion in the United States to be $276 billion. While this is a sizeable number, larger than many of the world's economies, it has been estimated that 25-30% of the total, or $70-80 billion, could be saved by using state-of-the-art corrosion management practices. In addition to the cost savings, corrosion can result in public and industrial safety issues.
CC Technologies (Dublin, Ohio) conducted the research in a cooperative effort with the U.S. Department of Transportation Federal Highway Administration (FHWA). NACE International - The Corrosion Society worked with Congressional representatives to secure $1 million in federal funding for the study.
The study identified the direct cost of corrosion in five major sectors of the economy - infrastructure, utilities, transportation, production & manufacturing, and government.

• What to do when a metal roof begins to leak or rust . . .
- Call a licensed roofing consultant, architect or contractor and ask for a roof survey.
( ie. Roofing Contractors Association of BC www.rcabc.org)
- Determine exactly what the problems are.
- Develop a repair or replacement strategy that not only solves today's problems but one that is also compatible with a long term maintenance plan.
