Synthetic Roofing Underlayments for Superior Water Protection

Protect roofs with a tough, easy to install premium synthetic roof underlayments, for a trusted secondary layer of water protection.

New DuPont™ Tyvek® Protec™ is a portfolio of engineered synthetic roofing underlayments with industry-leading walkability and are available in a range of roll weights and UV exposure that offer high-performance with a variety of roofing materials, from asphalt shingles to slate. All three options feature a unique embossed pattern that allows for better traction and grip while walking on the roof. They are also lightweight, durable and provide a wrinkle-free surface for smoother installations. 

DuPont™ RoofLiner is a premium synthetic roof underlayment that can provide excellent water protection and ease of installation, as a roofing felt alternative, under a range of roof coverings.

Professional Grade Peace of Mind

All DuPont roofing underlayments have a Class A Fire Rating per ASTM E108 and is covered by limited warranties that range from 30 to 50 years.

High Compatibility

DuPont roofing underlayments can be used on roofs with a 2:12 slope or higher and are suitable for use with a variety of roof coverings. The list of approved roof coverings varies by product. Refer to each product’s specifications to determine which option is best suited for the chosen roof covering. 

Wet WeatherReady

During the construction phase, DuPont™ Tyvek® Protec™ and DuPont™ RoofLiner create a water-shedding barrier that keeps rain and snow from intruding into roofs and attics. After construction is complete, the DuPont synthetic roofing underlayment continues to perform as a secondary water barrier, and can help improve the overall life and integrity of the roof.

Maximum Coverage

With fewer overlaps, seams and fasteners, DuPont roofing underlayments offer maximum coverage on new construction applications, as well as re-roofs. For re-roofing applications, shingles must be removed prior to installation of DuPont synthetic roofing underlayments.

Easier Installation

DuPont synthetic roofing underlayments are lighter in weight and less labor-intensive than traditional roofing felt. One 10-square-footroll covers as much area as approximately five rolls of roofing felt. So there’s less time spent on material handling.
