How TPO Roofs Work
TPO is one of the most common single-ply membranes used on commercial low-slope roofsRoof Types - Low-slope roofs (flat roofs) are a type of roof system with less than a 3:12 pitch, most commonly found on commercial and industrial buildings. More. It is manufactured in wide sheets that are installed across the roof and fused together at the seams rather than glue to form a continuous waterproof layer.
The system relies on the integrity of these heat-welded seams to remain watertight. MembraneMaterial - A single-ply membrane is a roof covering that uses one continuous layer of material to waterproof low-slope roofs. More thickness, attachment method, and installation quality all influence how the system performs and what warranties are available.
Most TPO membranes are white, which reflects sunlight and reduces heat buildup rather than absorbing it.
