In Fort Johnson, SC, the Department of Natural Resources is facing a tough decision. A leaky roof at the regional administration office needs to be replaced, and the choice is between copper and asphalt. The copper roof carries a 50 to 100 year lifespan, but at a cost of $160,000. The asphalt shingle roof is expected to cost significantly less, but is only expected to last 10 to 20 years.
The advising engineers said the savings in maintenance and repair on a copper roof, as well as the longer time span before it needs to be replaced, will make it worth a lot more than $100,000 the department estimates it could save by putting in an asphalt shingle roof. A shingle roof is expected to cost about $60,000.
“It’s either a cost-effective expenditure or it’s not. It all depends on what saves more money,” said state Sen. Mike Rose, R-Summerville, who has criticized some department spending as not needed.
