Expert Verdict — Reviewed by the SuperArbor Pro Desk
Pre-taped curb flashing removes the field-laminating step, so it is a strong choice when you want repeatable, clean curb details across many penetrations. Pick the roll width from curb height plus the required horizontal leg, and keep the 6 in. tape version for curbs where extra bond width helps. Clean and prime the substrate per the JM specification before adhering.
Adhered flashing work on curbs can put you near roof edges and penetrations; maintain fall protection and follow the membrane manufacturer's priming and temperature guidelines.
Order JM EPDM Pre-Taped Curb Flashing in Black or White to flash curbs fast with a factory-laminated tape edge.
