Roofing by Michel

Michel did my roof with a 20 year warranty on the shingles and it has been giving me problems since it was done over a year ago. Every time there is a heavy wind, the shingles start flying. I call him both on his cell and at home and there is no response, I have also driven to his home and there is nobody there. Meanwhile I have a leaking roof due to the shoddy workmanship so I have to call someone else to fix the problem which makes me say that please do to use Michel as your roofer as he is unreliable and does not respond to your calls when you need him.
