Surround VR Underlayment, from Typar, reduces the amount and weight of material needed for roofing jobs. The manufacturer says that one roll of Surround VR covers the same area as five rolls of #30 felt, but weighs seven times less and is 10 times stronger. Made from a waterproof synthetic polymer material, the underlayment is slip resistant on dry surfaces and still provides traction when wet. Surround VR works in any application, including shingles, tile, slate, and metal roofs, and it will not crack or wrinkle in extreme weather.
