Ice Dam Protection

Protect your home or building from damaging Ice Dams with Roofnado™ LapLock™ PSU HT

With Roofnado LapLock PSU installed, your roof deck, internal roof space and wall cavities remain dry and protected from ice dams. If left unprotected, pooling water can rot your roof deck and supporting beams. Water can seep into your roof space and wall cavities causing serious damage to your valuable home or building.

LapLock™ Dual-Locking Lap Seal Technology

With LapLock™ PSU HT, every lap is protected from water ingress by a dual-action locking adhesive ! The first lock is a 3" wide strip of highly sticky adhesive that pressure bonds to the 3" overlap section below it. And the second lock is a 1" wide strip of adhesive that locks upward onto the underside adhesive of the sheet above forming a water-tight seal. Correctly installed with the dual-locking laps, dammed water or wind-driven water is blocked from penetrating the roof deck.
