- PROJECT OVERVIEW
A New Deck, Finished in a Day
This flat roof project in County Dublin was completed on a new 18mm OSB deck, which was carefully prepared and cleaned by Connolly Fibreglass prior to installation. This preparation provided a clean and suitable surface for the TriRoof FLEX liquid overlay system to bond effectively with the roof substrate.
To help manage rainwater runoff and enhance the overall finish, trim details were installed around the roof perimeter. These features contributed to improved drainage while creating a cleaner, more professional appearance.
The installation was completed within a single day, keeping disruption to a minimum and allowing the project to progress efficiently. The result was a neatly finished roof featuring the seamless TriRoof FLEX liquid overlay system.
