Properties evaluated:  Physical properties  Fire classification 2.0 USES VersaShield® Fire-Resistant Roof Deck Protection (previously known as VersaShield® Underlayment) is used as an alternative to ASTM D226, Type I or Type II, roofing underlayment specified in Chapter 15 of the IBC and Chapter 9 of the IRC. When installed in accordance with Section 4.2.1 of this report, VersaShield® Fire-Resistant Roof Deck Protection can also be used over existing wood shakes or shingles as an alternative to the covering materials specified in Section 1510.4 of the IBC or Section R907.4 of the IRC. VersaShield® Fire-Resistant Roof Deck Protection is also used as a component of classified roofing assemblies as described in Section 4.3, when installed in accordance with this report. 3.0 DESCRIPTION VersaShield® Fire-Resistant Roof Deck Protection is a resin-bound chopped-glass-fiber substrate, coated on both sides with a mineral-filled aqueous coating. The underlayment has a weight of 15 pounds per 100 square feet (0.73 kg/m2), and is supplied in rolls. 4.0 INSTALLATION 4.1 General: VersaShield® Fire-Resistant Roof Deck Protection is installed in accordance with the requirements of the applicable code, the manufacturer’s published installation instructions and this report. The manufacturer’s published installation instructions are to be available at the jobsite during the installation. VersaShield® Fire-Resistant Roof Deck Protection is limited to use over spaced or solid sheathing, or over existing asphalt shingles, wood shakes or wood shingles installed on spaced or solid sheathing. Prior to application of the underlayment, the deck surface is to be free of dust and dirt, loose nails and other protrusions. Damaged sheathing is to be replaced. The underlayment is applied at right angles to the slope of the roof, beginning at the low point of the roof, and is laid with minimum 2-inch (51 mm) horizontal and 6-inch (152 mm) vertical lapped joints. It is attached with a sufficient number of nails, having tin caps or 1-inch-diameter (25.4 mm) plastic caps, to hold the underlayment in place until the roof covering is applied, except in areas subject to high winds where the underlayment fastening must comply with the high wind attachment requirements specified in Section 1507 of the 2012 IBC or Section R905 of the 2012 IRC. The underlayment may be bent to a minimum 1/2-inch (12.7 mm) radius, but is not to be creased. At junctions between the roof deck and vertical surfaces, the underlayment is installed a minimum of 3 inches (76 mm) up the vertical surface. In areas of the roof required to have an ice barrier under Chapter 15 of the IBC or Chapter 9 of the IRC, a self- adhesive polymer bitumen sheet, complying with ASTM D1970 or the ICC-ES Acceptance Criteria for Self-adhered Underlayments for Use as Ice Barriers (AC48), is to be applied. The underlayment is to be applied over the solid substrate in sufficient courses so that the underlayment extends up the roof a distance equal to the distance inside the exterior wall line of the building that is specified by the applicable code. The underlayment, applied in the field of ESR-2053 | Most Widely Accepted and Trusted Page 2 of 4 the roof, is to completely overlap the ice barrier (severe climate underlayment) protection a minimum of 2 inches (51 mm). Installation of the roof covering can proceed immediately following the underlayment application. The underlayment is to be covered by a roof covering within the time set forth in the manufacturer’s published installation instructions. 4.2 Reroofing: The existing roof must be inspected in accordance with Section 1510 of the IBC or Section R907 of the IRC. The new roof covering is installed over the VersaShield® Fire-Resistant Roof Deck Protection in accordance with the roof covering manufacturer’s published installation instructions. The new roof covering must be recognized in a current ICC-ES evaluation report, and, when applicable, the evaluation report must address installation over wood shake, wood shingle or asphalt shingle roofs. 4.2.1 Existing Wood Shakes or Shingles: Where the application of a new roof covering over wood shingle or shake roofs creates a combustible concealed space, VersaShield® Fire-Resistant Roof Deck Protection can be used as an alternative to the covering materials specified in Section 1510.4 of the IBC or Section R907.4 of the IRC. The underlayment covers the entire existing wood roof. Battens used for the new roof covering system are installed over the underlayment. The underlayment may be placed under or over counterbattens, spaced a maximum of 24 inches (610 mm) on center. The underlayment is fastened to the counterbattens with a sufficient number of nails, having tin caps or 1-inch-diameter (25.4 mm) plastic caps, to hold the underlayment in place until the horizontal battens and roof covering are applied. When counterbattens are installed over the underlayment or when counterbattens are not used, the underlayment is fastened directly to the existing roof covering in the same manner. 4.2.2 Existing Asphalt Shingles: When installed over existing asphalt shingles, the underlayment is applied over the existing roof covering and fastened through the shingles to the sheathing with a sufficient number of nails, having tin caps or 1-inch-diameter (25.4 mm) plastic caps, to hold the underlayment in place until the roof covering is applied. 4.3 Roof Classification: When installed in accordance with this report, VersaShield® Fire-Resistant Roof Deck Protection can be used as an alternative to Exception 2 to Section 1505.2 of the 2012 and 2009 IBC, the Exception to Sections 1505.2 and 1505.3 of the 2006 IBC, and Section R902.1 of the IRC; or any roofing assembly having a Class A, B or C roof classification, without reducing the roof classification. When installed in accordance with Section 4.1 and Table 1 of this report, roofing assemblies incorporating VersaShield® Fire-Resistant Roof Deck Protection have the roof classification specified in Table 1. The roof coverings must be recognized in a current ICC-ES evaluation report as shown in Table 2. 5.0 CONDITIONS OF USE The VersaShield® Fire-Resistant Roof Deck Protection described in this report, complies with, or is a suitable alternative to what is specified in, those codes listed in Section 1.0 of this report, subject to the following conditions: 5.1 Installation must comply with this report; the manufacturer’s published installation instructions and the applicable code. In the event of a conflict between the manufacturer’s published installation instructions and this report, this report governs. 5.2 Installation is limited to roofs with a minimum slope of 2:12 (16.67 percent slope) or to the minimum slope required for the roof covering in accordance with the applicable code, whichever is greater. 5.3 Installation is limited to use with roof coverings that do not involve hot asphalt or coal-tar pitch. 5.4 Installation is limited to use with approved roof coverings that are mechanically fastened through the underlayment to the sheathing or rafters. 5.5 Installation is limited to roofs with ventilated attic spaces in accordance with the requirements of the applicable code. 5.6 VersaShield® Fire-Resistant Roof Deck Protection is produced in Conover, North Carolina, under a quality control program with inspections by ICC-ES. 6.0 EVIDENCE SUBMITTED Data in accordance with the ICC-ES Acceptance Criteria for Nonasphaltic Fiberglass-based Roof Underlayment (AC160), dated January 2000 (editorially revised February 2014). 7.0 IDENTIFICATION Each roll of underlayment bears a label indicating the GAF name and address, the plant identification, the product name, the roll number, and the evaluation report number (ESR-2053).
