@markmalone3786 No we do not ever use PVC. PVC is a great product...pricey though. PVC was designed originally for roofs rhatbhave somw sort of environmental fallout that would degregate typical roofs, like a chemical plant for instance. Dollar for dollar rhe TPO is rhe best roof system for majority of roofs. Also compared to PVC ,TPO will be more flexible as time goes on. Thanks for watching.
