Overview
ZIP System Peel & Stick Underlayment uses rubberized asphalt and an adhesive backing for full roof deck applications. It covers areas such as eaves and valleys while forming a waterproof nail seal barrier.
The membrane is designed to block water intrusion and create a roof moisture barrier. Also, its rubberized asphalt technology supports sealing around nails for a waterproofing system. The slip-resistant surface supports traction and easier handling during installation.
This peel and stick roof underlayment comes in a 36-inch by 66-foot roll with 200 square feet of coverage.
Key takeaways
- The membrane supports full roof deck protection across areas including eaves and valleys.
- Rubberized asphalt forms a nail seal membrane that blocks water intrusion.
- The self-adhesive backing supports direct application across roof decks.
- A slip-resistant surface increases traction and supports easier application.
- The roll measures 36 inches by 66 feet and covers 200 square feet.
- Standard-temperature and high-temperature versions carry ratings of 180°F and 260°F.
What the product is designed to do
This roofing underlayment is designed for full roof deck protection. Also, it covers eaves and valleys while helping protect against ice dam leaks.
The rubberized asphalt forms a nail seal membrane around fastener penetrations. As a result, the membrane blocks water intrusion and creates a roof moisture barrier.
The system also supports a continuous air and water barrier when used with compatible ZIP System components. The adhesive waterproof roof membrane uses a self-adhesive format for roof deck application.

Installation and placement notes
The self-adhesive format supports application across full roof decks. Also, the membrane is intended for placement across eaves and valleys.
An embedded pull cord splits the liner on demand. Next, the adhesive backing supports placement against the prepared roof deck.
The slip-resistant surface increases traction during installation. However, the roll weighs 51 pounds, so handling should account for its size and weight.
Proper installation requires attention around nails and roof transitions. The rubberized asphalt is formulated to seal around nails and maintain the waterproofing layer.
When used with ZIP System sheathing and tape, the assembly qualifies for the ZIP System Leak-Free 30-year Guarantee. This condition ties the guarantee to the named system components.
