Tornado Radiant Barrier Underlayment goes down before every panel — a Class A+ fire-rated, radiant, sound-dampening, self-adhered ice & water shield built for Miami's heat and storms.
Most underlayments carry one rating. Tornado is built to carry five — without adding a second layer to the deck.
The highest fire-resistance rating a roof underlayment can carry, tested against severe fire exposure.
A reflective face that bounces heat back before it ever reaches your attic — not just a fire layer, a heat layer.
Extra dampening between the panel and the deck, so rain and hail hit quieter than they would on a bare roof.
A fully self-adhered layer that keeps the deck dry even if wind or storm damage compromises the panel above.
A premium self-adhered membrane rated to seal around fasteners and hold up against wind-driven rain and ice-dam backup at eaves, valleys, and penetrations.
Most underlayments do one job: keep water out. Tornado does five. It's the layer we install between your roof deck and every Tornado metal panel — reflective on top to bounce back heat, self-adhered underneath as a secondary water barrier and ice & water shield, dense enough to quiet down rain and hail, and rated Class A+ for fire resistance.
It's built to go under our own Tornado steel and aluminum panels, and every roll carries Miami-Dade County approval — the same standard our panels are held to.
More on Our Standards →Filter by the risk you're building against — Tornado is rated to handle all five at once.
Reflects heat away from the roof deck instead of letting it soak into the attic.
Class A+ fire resistance rated to help slow flame and ember spread across the roof assembly.
A fully self-adhered secondary barrier that keeps the deck dry even if wind or storm damage compromises the panel above.
Added mass and dampening between the panel and deck to cut down rain and hail noise inside the home.
A self-adhered ice & water shield membrane that seals tight around fasteners and holds up against wind-driven rain and ice-dam backup at eaves, valleys, and penetrations.
