02 Why It Works

Protect your home’s first line of defense.

  • Speed & Ease of Installation

    Quick and simple two-step installation eliminates the need for felt, so interior crews can begin quickly.

  • Protection Against Water Intrusion

    The combination of a built-in water-resistant barrier and taped panel seams protects against water intrusion and eliminates the need for traditional felt.

  • Durability for High-Wind Zones

    High-strength engineered wood panels with Structural 1 rating provide strength and stiffness so you can meet high-wind-zone requirements.

  • Avoid Underlayment Repair

    With ZIP System sheathing panels, the underlayment is manufactured into the engineered wood panel, eliminating the risk of the weather barrier tearing off, so you can say goodbye to felt repairs.

  • Quicker Rough Dry-In

    Simply install the panels and tape the seams to achieve a quicker rough dry-in, allowing mechanicals and other trades to start sooner.

  • 30-Year Limited Warranty

    The ZIP System is backed by a 30-year limited warranty and 180-day Exposure Guarantee[1].

Compatible with any covering & underlayment.

ZIP System panels install fast and stay flat, for a roof that looks as good as it performs. ZIP System sheathing and tape provides a water-resistant, durable underlayment for many finished roof coverings including metal, tile and asphalt shingles, fiberglass shingles, and cedar shingles.
