I have a metal roof and glass windshield from fortress atv. Purchased it through a local dealer. I have had it since 07 with no problems other than the sound deadening material needing to be re-glued on the roof after a couple of years. The only thing I was not sure about when I bought it was the how much of the view the metal frame for the windshield blocked but after a few days it was not even noticed anymore. The bottom section of the windshield is removable for summer time use to get more airflow.
