Viking Barriers manufactures and distributes underlayment for use under all types of sloped roofing. Viking Barriers has three products — Viking Shield, Viking Armor, and Xtreme, which all offer our industry cutting-edge SLIPGUARD resistant feature. SLIPGUARD offers a front and back enhanced slip-resistant walking surface. If your roofing project demands a premium 50-year warranty, the safe and comfortable walking surface of Viking Armor is more durable than 30 lb. felt replacement.

Viking synthetic underlayment products do not expand or contract, they lay flat without buckling, and are completely inert to mold growth for up to 6 months. Viking Barriers Xtreme, our premium-grade roof underlayment, is now available with the next-generation self-adhered backing.

All Viking Barriers underlayments meet or exceed ASTM D 4869, ASTM D 226, ICC-ES AC188, ICC-ES AC188, FBC (HVHZ) TAS 103, Miami-Dade 2014 FBC

Viking Shield

Viking Shield is 25 times stronger and more durable than the leading 15-pound felt. Its superior lay-flat properties and water resistance keep it from warping, winkling, and cracking in cold weather, while its enhanced UV protection reduces heat buildup on hot days. It’s also 100% inorganic, so it will not rot or mold.

With less weight per roll, Viking Shield is easier to handle during all stages of installation, while remaining strong enough to resist tearing and stretching in high-traffic areas and during high winds. Viking Barriers’ proprietary SlipGuard skid-resistant surface offers dynamic steep-slope traction, ensuring the best walking surface available. Plus, Viking Shield is environmentally responsible and may contribute to your LEED and RGBP ratings.
