Surround your homes with protection.

The roofing deck is the area that supports the actual roofing material, and protecting it from moisture is key to assuring the lifespan of the roof and the long-term durability of the home. So start protecting your home at the top with Surround™ SR Underlayment, a TYPAR® brand.

Surround SR roofing underlayment

Whether your roof is covered with shingles, shakes, tile, slate or metal, be sure it’s protected with Surround SR Underlayment. A smart alternative to felt, it is water’s toughest opponent, creating a secondary water barrier that reduces the incidence of leaks caused by storm damage, wind-driven rain, ice dams and worn roofing materials. It is a waterproof, synthetic polymer material that will protect your homes against moisture intrusion.  

In addition to superior weather protection, Surround SR Underlayment offers these advantages:

  • Stronger—10 times stronger than 30# felt for the ultimate tear resistance, so it will not blow off during installation and helps eliminate the need for costly roof repair.

  • Drier—the unique slip-resistant surface is waterproof to prevent moisture issues.

  • Lighter—up to 10 times lighter than 30# felt so it’s easy to carry onto a roof.

  • Faster—in addition to having five times more underlayment per roll than felt, the rolls are also 25 percent wider for quicker roof deck coverage.

Backed by the manufacturers of proven TYPAR® weather-resistant barriers, it’s one more component in the line of defense against the elements.

Surround SR Underlayment meets the more stringent requirements of ICC AC48—Acceptance Criteria for Roof Underlayment for Use in Severe Climate Areas.
