CD Builders Inc

I had a 2 car garage built in 2000 by CD Builders. I discovered years later after I found numerous roof leaks that half the roof nails were loosely installed. I also had vinyl siding installed incorrectly resulting the total rotting of the wall where the garage doors are. A section of the roof never had tar paper put on and the Tyvek protective shield had been cut into on many sections during the installation. Half the roof trusses did not have support which could have resulted in a collapse but I installed 4x4s under each truss before this could have happened. I have tried to reach the owner of CD Builders many times but he has never returned my phone call.
