Installation of Plywood Sheathing at the Roof Mate Line on a Permanent Modular Building

The materials used in permanent modular construction are no different than site built structures. This includes critical features like roofing applications. For large or small parapet wall facilities with low slope roofs, Ramtech prefers to use and install TPO (Thermoplastic Polyolefin) roofing material because of its durability and flexibility. This type of roofing material will adapt to a building’s movement and setting while still remaining resistant to impact damage, tears, or punctures.

Installation of DensDeck Prime Roof Board at the Roof Mate Line on a Permanent Modular Building

TPO roofs are resistant to dirt, algae buildup, and debris and will improve a building’s energy efficiency because of it’s substantial heat-reflective properties and the able to minimize the urban heat island effect. They’re also environmentally friendly with ability to be 100% recycled at the end of their lifespan. Ramtech applies the TPO material during the construction phase in our manufacturing plant, then seams the roof at the mate lines it the jobsite. This can be done quickly by nailing in both the plywood sheathing and DensDeck prime roof board before overlaying the TPO to complete the assembly.
