How UnderCover Systems Works

Undercover Systems is a modular designed deck roof system for the underside of raised or multi-story decks. This roof/ceiling system consists of individual ceiling panels and integrated gutters that both collect water from the system and also are the support members for the ceiling. All water and debris is channeled from the ceiling panels to the perimeter gutter system then exits through periodic downspouts.
