The Most Specified Commercial Flat Roof Membrane
Thermoplastic Polyolefin (TPO) is the dominant commercial roofing membrane in North America — and for good reason. Heat-welded seams, excellent UV resistance, and up to 30-Year NDL warranties from Johns Manville make TPO the default specification for most commercial flat and low-slope roofs.
