Caution: Always learn and observe safe roofing practices as per the local building code requirements. Always use caution when walking on sloped roof decks and Raptor™ underlayments. Do not walk on unsecured Raptor™ or any other loose roofing material lying on sloped roof decks. Dust, dew, water, or debris creates unsafe conditions on the roof. The presence of any foreign matter may drastically change the coefficient of friction (traction) on Raptor™ or any other material on a sloped roof deck. Failure to always use proper safety equipment and footwear can result in serious injury or even death.
