National Nail has expanded its STINGER line of roofing products with three ICC-certified synthetic underlayments: EXO50, EXO35 and EXO25. The underlayments are UV-resistant and can be exposed for up to six months. The synthetic woven fabrics offer high tear strength, and proprietary non-skid additives provide better roof deck contact for high slip resistance. Each roll is lightweight and, with 10 squares per roll, fewer rolls need to be carried to the roof. In addition, preprinted nailing patterns and overlap lines speed installation. STINGER cap fasteners (StaplePac and NailPac) and STINGER cap hammers, cap staplers, and cap nailers are recommended for installing all STINGER EXO products.
