82 squares of new 60 mil Johns Manville TPO, fully adhered, on a commercial building in Fountain City.
The roof was a layover — 1” ISO insulation board installed over the existing surface, then the TPO membrane adhered on top. No tear-off. Adds insulation value, extends the life of the building envelope, and keeps the job cost down.
60 mil is premium spec. Fully adhered means no fasteners penetrating the membrane. This system is built for decades.
