The TPO Roof Installation Process: A Step-by-Step Walkthrough

What actually happens on a commercial TPO reroof, from tear-off to warranty registration — explained in plain English.

Pre-construction

A proper TPO reroof starts weeks before crews arrive: submittals to the manufacturer, permit filing, insurance certificates, HVAC coordination, and building-owner communication about noise and access.

Tear-off of existing system to deck
Deck repair and re-nailing
Vapor barrier + polyiso insulation + cover board

Why Retrofitting Your Commercial Metal Roof with Flute Fill, Cover Board and TPO Is a Smart Investment

What Is a Flute Fill TPO Retrofit? On older metal roofs, the ribs or “flutes” create an uneven surface that makes waterproofing and insulation difficult. In a metal roof retrofit, rigid EPS or polyiso flute fill insulation is custom‑cut to sit inside those flutes, then a cover board and single‑ply membrane—often TPO—are installed over the top to create a smooth, watertight roofing system. This turns a failing exposed‑fastener metal roof into a modern, high‑performance low‑slope system without removing the existing panels.
