Michael Patota v. CertainTeen Corporation is a federal class action lawsuit that revolves around claims that CertainTeed’s fiber cement siding has been “severely defective”.

If you have had CertainTeed WeatherBoard Fiber Cement Siding installed on your home anytime between now and 2002 you are considered a class member of this lawsuit. More details can be found here.
