VB Synthetics manufactures and distributes underlayment for use under all types of sloped roofing. VB Synthetics 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.

VB Synthetic 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 VB Synthetics Underlayments meet or exceed ASTM D 4869, ASTM D 226, ICC-ES AC188, ICC-ES AC188, FBC (HVHZ) TAS 103, Miami-Dade 2014 FBC
