Review of Express Roofing Systems Limited

In Jan.2015 I purchased a 7,000.GHC roof from EXPRESS ROOFING; within 6 months time the roof started showing significant signs of rusting---all my efforts to get EXPRESS ROOFING to address the problem were ignored, and in fact after a time they stopped answering their phone..it's now less than 2 yrs later, and except for the interior roofing the 7000GHC roof has fallen apart,with pieces still coming off in places, I've included pictures to show EXPRESS ROOFING's work, and to prevent any other unsuspecting customer from experiencing what I have experienced from EXPRESS ROOFING in Ghana ! Thank you
