The shingles are manufactured with a proprietary formulation using both high-density and low-density polyethylene polymers and other additives. 3.2 DaVinci Slate Roof Shingle: The DaVinci Slate roof shingle is available in various colors and in widths of 6, 7, 9, 10 and 12 inches (152, 178, 229, 254 and 305 mm) with a length of 18 inches (457 mm). Exposure is 6 to 71/2 inches (152 to 191 mm), resulting in an installed weight of 325 to 260 pounds, respectively, per 100 square feet (15.9 to 12.7 kg/m2). See Figure 1 [10- inch- and 12 -inch -wide (254 and 305 mm) shingles shown] for further details. 3.3 DaVinci Shake Roof Shingle: The DaVinci Shake roof shingle is available in various colors and in widths of 4, 6, 7, 8 and 9 inches (102, 152, 178, 203 and 229 mm) with a length of 22 inches (559 mm). Exposure is 9 to 10 inches (229 to 254 mm), resulting in an installed weight of 324 to 288 pounds, respectively, per 100 square feet (15.8 to 14 kg/m2). See Figure 2 [9 -inch -wide (229 mm) shingle shown] for further details. 3.4 Underlayment: Underlayment must be a minimum of one layer of Type II (No. 30) asphalt -saturated organic felt, complying with ASTM D 226. Where an ice dam membrane is required as noted in Section 4.2 of this report, an ICC -ES evaluation report indicating the membrane's compliance with requirements of the ICC -ES Acceptance Criteria for Roof Underlayments for Use in Severe Climate Areas (AC48) must be submitted to the code official. 3.5 Flashing: Flashing must be minimum 16-ounce/ft2 (No. 23 gage) copper or other corrosion -resistant metal with a thickness of not less than 0.019 inch (0.483 mm). See Section 4.5 for valley flashing. 3.6 Fasteners: To secure the roof shingles to the sheathing, 11/2 -inch - long -by -1/a -inch -diameter -shank (38 mm by 3.18 mm) hot - dipped galvanized roofing nails, with 3/8 -inch -diameter (9.5 mm) heads, must be used. No. 12 gage corrosion -resistant roofing nails with 3/8 - inch -diameter (9.5 mm) heads must be used to fasten the underlayment to the sheathing. Nails must have sufficient length to penetrate into the sheathing 3/4 inch (19 mm) or through the sheathing, whichever is less. No. 12 gage, ring -shank, corrosion -resistant nails must be used to secure flashing to the sheathing. Nails must be compatible with the flashing material, and have sufficient length to penetrate the sheathing 3/4 inch (19 mm) or through the sheathing, whichever is less. 4.0 INSTALLATION 4.1 General: The DaVinci Slate and DaVinci Shake roof shingles must be installed in accordance with this report, the applicable code and the manufacturer's published installation instructions. The manufacturer's installation instructions must be available at the jobsite at all times during installation.

Solid sheathing must be minimum 15/32 -inch -thick (11.9 mm) exterior -grade plywood, '/16 -inch -thick (11.1 mm) oriented strand board (OSB), or nominally 1 -inch -thick (25.4 mm) lumber. The sheathing must be structurally adequate and fastened to resist the wind loads as specified by IBC and UBC Section 1609, or IRC Section R301.2, for components and cladding. 4.2 Underlayment: Underlayment described in Section 3.2 is installed parallel to the roof eave with a 6 -inch (152 mm) lap on the ends, a 6 -inch (152.4 mm) side lap and a minimum 6 -inch (152 mm) lap over eaves. The underlayment is fastened, only as necessary to hold in place, with nails as described in Section 3.6. In areas where the average daily temperature in January is 25°F (-4°C) or less, or where there is a possibility of ice forming along the eaves and causing a backup of water, an ice dam membrane as described in Section 3.4, in addition to the Type II (No. 30) underlayment, is required on all eaves, valleys, and gable ends, and around roof projections. At roof eaves, the ice dam membrane must extend from the eave's edge to a point 24 inches (610 mm) inside the exterior wall line of the building. 4.3 Roof Shingles: Starting with a row of 12 -inch -wide (305 mm) DaVinci Starter Slates or Shakes, the shingles must extend approximately 1 inch (25.4 mm) over the eaves and 3/4 inch (19 mm) over the rakes. The shingles are secured to the sheathing using two fasteners, as described in Section 3.6, through the premolded nail markers. The field shingles are installed flush with the starter slate or shake shingles on the outer and lower edges. A maximum gap of 3/9 inch (9.5 mm) is recommended between shingles, with a minimum 1/4 -inch (6.4 mm) gap required. The gaps between shakes at adjacent courses must be offset a minimum of 11/2 inches (38 mm). Maximum allowable exposure is 71/2 inches (191 mm). 4.4 Hips and Ridges: The top of hips and ridges must be covered with a minimum 6 -inch -wide (152 mm) flashing as noted in Section 3.5. 4.4.1 DaVinci Slate Roof Shingles: On top of the flashing, 7 -inch -wide (178 mm) DaVinci Slate roof shingles are installed on each side of hips while 9 -inch -wide (229 mm) DaVinci Slate roof shingles are installed on each side of ridges, with the shingles butting at the top. Both hip and ridge shingles must be installed with a 6 -inch (152 mm) exposure. Shingles and flashing must be secured with fasteners as noted in Section 3.6. 4.4.2 DaVinci Shake Roof Shingles: On top of the flashing, 6 -inch -wide (152 mm) DaVinci Shake roof shingles are installed on each side of hips and ridges, with the shingles butting at the top.
