The underlayment may be used as a component of classified roof assemblies when installed as described in this report. The underlayment may also be used as an alternative to the ice dam membrane specified in IBC Chapter 15 or the ice barrier specified in IRC Chapter 9. 3.0 DESCRIPTION Deck Defense roofing underlayment is a synthetic sheet- type underlayment comprised of a woven core coated on both sides with a polymer coating. The underlayment has a nominal overall weight of 2.9 pounds per 100 square feet and is produced in rolls of varying sizes. 4.0 INSTALLATION 4.1 General: Installation must comply with the applicable code, this report and the manufacturer's published installation instructions. In the event of conflict between the manufacturer's instructions and this report, this report governs. The installation instructions must be available at the jobsite during installation. Prior to application of the underlayment, the deck surface must be dry and free of dust and dirt, loose nails, and other protrusions debris. Damaged sheathing must be replaced. The underlayment is laid horizontally (parallel to the eave) starting at the lowest eave point, printed side up, with 4-inch (102 mm) horizontal (head) laps and 6-inch (152 mm) vertical (end) laps. Overlaps run with the flow of water in a shingling manner. The underlayment is attached to the roof deck as set forth in the manufacturer's published installation instructions, except in areas subject to basic (3-second gust) wind speeds in excess of 110 miles per hour (49 m/s), where the underlayment must be applied in accordance with IBC Section 1507.2.8.1 or IRC Section R905.2.7.2 for asphalt shingle roof coverings or IRC Section R905.3.3.3 for concrete and clay tile roof coverings, as applicable. When battens or counterbattens are installed over the underlayment, the underlayment need only be preliminarily attached pending attachment of the battens or counterbattens. In areas of the roof required to have an ice dam barrier under Chapter 15 of the IBC or Chapter 9 of the IRC, two layers of the roofing underlayment must be cemented together with a roofing cement complying with ASTM D4586, for a minimum distance of least 24 inches (610 mm) inside the exterior wall line of the building. The roofing underlayment, in the field of the roof, must overlap the ice barrier. The minimum roof slope to which the underlayment is installed and the minimum number of layers of underlayment must comply with the applicable requirements set forth in IBC Chapter 15 or IRC Chapter 9, as applicable, based upon the type of roof covering being installed over the underlayment. Installation of an approved roof covering can proceed immediately following application of the roofing underlayment. The underlayment must be covered by the roof covering within the time period set forth in the manufacturer's published installation instructions. *Revised August 2013
