Expert Verdict — Reviewed by the SuperArbor Pro Desk
Coated metal like this lets you fabricate custom flashing and edge details that weld directly to the field membrane, eliminating sealant-only seams at terminations. Keep the TPO face out during brake bending and use compatible hand rollers to avoid scuffing. Match the membrane system (adhered or mechanically fastened) and choose white for reflectivity where color doesn't need to match existing trim.
Sheet metal edges are sharp; wear cut-resistant gloves and use proper fabrication and lifting practices with 4' x 10' sheets.
Order the JM TPO Coated Metal Sheet 4' x 10' Gray for weldable, watertight flashing fabrication.
