A sheet material (e.g., underlayment roofing material) is disclosed having a high coefficient of friction and being fabricated from at least one structural layer and at least one laminated layer. The structural layer can be constructed of a woven product that can include loom fibers that may be twisted, can include a heavier strain material, and/or can include any material and/or method that creates a raised structure (e.g., raised area, raised line, etc.) in the structural layer's weave. Subsequently, these raised structures in the structural layer's weave can create small squares, lines, and/or other designs in the underlayment roofing material that provide increased friction and/or traction. |
