DANIEL R T asked:

I have been charged with the duty of figuring out how much it will cost to have the roof on our condo repaired/replaced when this 4-year old one wears out. Does anyone have a rough estimate per sq. ft. for this job? Our roof is flat and has a silvery surface. There are no pebbles or shingles involved in it. I live in Chicago (if that makes any difference.)
