Review of Express Roofing

I paid over GHC7,000. to EXPRESS ROOFING for my roofing--EXPRESS ROOFING laid the roof in Jan 2015,& within 6 months the roofing started showing bad signs of rusting.immediately contacted EXPRESS ROOFING;they sent a yg. man who has been the EXPRESS ROOFING ' front' boy..the REAL OWNERS of EXPRESS ROOFING continue to hide themselves( that's why THERE IS NO NAME on their AD or website for you to contact!!) It is Sept2016--all my attempts to even talk with 'the owner/management have failed AND THE EXPRESS ROOF THAT COST ME GHC7000 IS TOTALLY RUSTED & FALLING APART...EXPRESS ROOFING COMPANY SELLS RUSTING INFERIOR ROOFING SHEETS...BE FOREWARNED!
