Salesman had a good pitch. Convinced me to install over shingles that already had leaks in 2010. Bob Everhart with Advanced Metal would not return my calls, know I am out of 30,000 dollars, will cost me another 16,000 to remove and replace with shingles. Did anyone start a class action lawsuit with this company I understand that this company moves around a lot to avoid warranty and the owner has been convicted of fraud in other states.
