TPO Replacement and Moisture
Insulation condition and attachment matter before a new membrane is selected. Wet insulation or unsound substrate needs attention instead of being enclosed. Roof slope, primary drains and overflow paths determine how water leaves the finished assembly.
Replacement scope includes the existing roof layers, removal or recovery eligibility, insulation, fastening or adhesion method, edge details and equipment flashing. The suitable approach depends on the building and system requirements.
