UNDERLAYMENT AND DECK LEVEL FLASHING

not required under
standard installation conditions, blind nail as necessary. Refer to the manufacturer’s instructions for full

Start with a half-width strip at the edge of the roof (eave or rake). Lap a full-width strip 18” to create a
double layer of underlayment. Repeat this fastening and waterproofing process while moving uproof.
