Installing TPO requires a full roof evaluation, proper measurements, insulation if needed, membrane sheets, fastening materials, flashing, adhesives, and professional heat-welding equipment. The roof surface must be clean, dry, and structurally sound before installation begins.

Special attention is needed around roof drains, vents, HVAC units, edges, and wall connections because these are common leak points. The seams must be heat welded correctly to create a watertight bond. Depending on the condition of the old roof, removal or repairs may be required first. Skilled flat roofing work helps ensure the system performs properly.
