3 17 "Asphalt shingle roof systems may be applied directly to the following roof deck substrates: (2 bullets)." Wood Panels. "Wood-panel roof decks can be subdivided into two general types: plywood roof decks and oriented strand board (OSB) roof decks." "When plywood is used as a roof deck material, NRCA recommends the use of a minimum of four-ply, 15/32-inch-thick plywood for 16-inch rafter spacings, and four-ply, 5/8-inch-thick plywood for 24-inch rafter spacings." When OSB is used as a roof deck material, a minimum of 15/32-inch-thick OSB is recommended for 16-inch rafter spacings and 5/8- inch-thickness OSB for 24-inch rafter spacings." 19 "Plywood and OSB sheathing panels should be installed with about 1/8-inch minimum gaps at panel edges to allow for expansion of the panels." 1.2 Wood Planks and Wood Boards. "Wood planks are long, relatively thick pieces of lumber. Specifications sometimes vary in thickness from 2 inches up to 5 inches with the width dimension in the plane of the roof deck." "Wood boards are pieces of lumber that are less than 2 inches thick with square edges." 23 "There are different underlayment configurations that can be used for asphalt roof systems. These configurations can be categorized as follows: (3 bullets)." 26 Roof Slope: "For roof substrates having slopes of 4:12 or more. NRCA recommends a minimum singlelayer underlayment be specified and applied horizontally in shingle fashion." "For roof substrates having slopes of 3:12 up to 4:12, a single layer of self adhering polymer-modified bitumen underlayment or a minimum double-layer underlayment should be specified. When a double layer underlayment is specified, it should be applied horizontally in shingle fashion, with half the roll width minus 1 inch exposure and half the roll width plus 1 inch underlap." 26 Underlayment Configurations: "Generally. these configurations can be categorized as follows: (3 bullets)." Single Layer of Mechanically Attached Underlayment: "For single-layer applications, the underlayment should be applied horizontally in shingle fashion and lapped a minimum of 2 inches and the end laps of a minimum of 4 inches are recommended. 26 Note and highlight Figure 2-1: Single-layer underlayment 27 Single-layer of Self-adhering Underlayment: "This configuration consists of one layer of self-adhering polymer-modified bitumen sheet applied over and entire roof deck. "Typically manufacturer s recommend side laps of a minimum of 3 ½ inches and end laps a minimum of 6 inches for self-adhering polymer-modified sheets installed as rood underlayments." Underlayment Application in High-Wind Areas: "For underlayment installed in areas subject to with speeds greater than 110 mph (2 bullets). "For underlayment installed in areas subject to with speeds greater than 120 mph (4 bullets). 31 "Asphalt shingles are designed for use as multilayered, water-shedding roof components that rely on the slope of a roof substrate to effectively shed water." Common dimensions for standard three-tab shingles are 12 inches by Exam Prep NRCA Steep-Slope Roof Systems

4 32 Figure 3-1: Shapes and styles of asphalt shingles. 33 Self-sealing Strip: "Commonly, asphalt strip shingles and laminated shingles contain adhesive, selfsealing strips." Asphalt Shingle Classifications: "Asphalt shingles classified according to ASTM D7158 as Class D are said to pass at a basic wind speed up to and including 90 mph; those classified as Class G are said to pass at a basic wind speed up to and including 120 mph; and those classified as Class H are said to pass at a basic wind speed up to and including 150 mph." 35 Figure 3-3: Asphalt shingles' wind-resistance classifications. 38 Fasteners: "Nails should be long enough to penetrate through all layers of roofing materials and achieve secure anchorage into a roof deck. Nails should extend a minimum of 1/8 inch through the underside of plywood or other acceptable wood panel decks less than 3/4 inch thick." Asphalt Roof Cement: "There are two common types of asphalt roof dement: flashing cement and lap cement." 40 Offset Patterns: "There are several offset or side-lap gauge patterns used with three-tab shingles, and the pattern used generally is selected based on manufacturer or installer preference, regional or climatic experience, or common practice." and 5 5/8-inch methods: "A more random visual effect of a finished roof system can be achieved by offsetting cutouts in neighboring courses." Shingle Attachment: "When attaching asphalt shingles, the intended location of fasteners depends on the particular shingle type. 42 Attachment of three-tab strip shingles: "Fastening of full-length three-tab shingles requires a minimum of four roofing nails per strip shingle positioned about 5/8 of an inch above the top of the shingle cutouts." "For areas considered to be high-wind regions, six-nail attachment of asphalt strip shingles may be required by the applicable building code." 43 Figure 3-4: Four-nail attachment locations for three-tab strip shingles. Figure 3-16: Six-nail attachment locations for three-tab strip shingles. Attachment of laminated strip shingles: "For standard-size (36-inch-wide) laminated strip shingles and metric-size (39 5/8-inch-wide) laminated strip shingles, manufacturers generally specify full-width shingles be fastened with four nails." "For areas considered to be high-wind regions, size-nail attachment of laminated shingles may be required by some building codes." 44 Figure 3-17: Four-nail attachment locations for laminated strip shingles Figure 3-18: Six-nail attachment locations for laminated strip shingles. 45 Hips and Ridges: "Asphalt shingles may be butted and nailed as work progresses up either side of a hip or a ridge." 1 Exam Prep NRCA Steep-Slope Roof Systems

5 Drip Edge Metal: "Drip edge metal is most common for asphalt shingle roof systems. Drip edge metal is typically fabricated in two configurations, L-type or T-type." 46 "NRCA suggests fastening drip edge metal at about 12 inches on center, slightly staggered. Spacing may need to be closer in highwind regions." "Also, drip edge metal should be fabricated from one of the following metal types and minimum thicknesses: (9 bullets)." Valleys: "A valley is created at the downslope intersection of two sloping roof." 47 "With asphalt shingle roof systems, there are three basic types of valleys: (3 bullets)" "Generally, fasteners should be kept back from the center of the valley a minimum of 8 inches." Open Valleys: "A metal valley is constructed by installing typically 8-foot or 10-foot lengths of corrosion-resistant metal from the low point to the high point in the valley." Figure 3-23: Underlayment centered in valley to channel water runoff down the valley Figure 3-24: Open valley using metal valley flashing. "A minimum 36-inch-wide layer of heavy weight felt, polymer-modified bitumen membrane or selfadhering underlayment is centered in the valley under the field underlayment." 48 "NRCA suggests valley metal for asphalt shingle roof systems be fabricated from one of the following metal types and minimum thicknesses: (9 bullets)" "NRCA recommends valley metal for use with asphalt shingles be a minimum of 24 inches wide." Closed-cut Valleys: "In closed-cut valleys, shingles on one side of the valley are installed across the valley and shingles from the other side are cut about 2 inches short of the centerline of the valley." 49 Woven Valleys: "Woven valleys are generally limited to three-tab strip shingles and light-weight laminated shingles on roof systems where the roof slope is 5:12 or more, making the valley sloped at 3'h :12." 50 Flashings: "Because roof systems are frequently interrupted by the intersection of adjoining roof sections, adjacent walls or penetrations such a s chimneys and vent pipes - all of which create opportunities for leakage - special provisions for weather protection must be made at these locations." 51 Vertical surface flashings: "There are four types of metal flashings commonly used at locations where an asphalt shingle roof system intersects a vertical surface: apron flashing, step flashing, cricket or backer flashing, and counterflashing." Figure 3-27: Sheet-metal Flashing components used at chimney Apron Flashings: "Apron flashings provide a weatherproofing transition material where a roof area intersects a head wall." 1 Exam Prep NRCA Steep-Slope Roof Systems

6 Step Flashings: "For asphalt shingle roof systems where a roof area intersects a vertical side wall, individual pieces of metal flashing are installed at the end of each shingle course." "NRCA recommends using metal step flashing that is 7 inches long by 8 inches wide for standard-size shingles..." 51 Cricket or Backer Flashing: "When a roof area intersects the upslope side of a chimney or curbed roof penetration. a cricket or backer flashing is installed." 52 "Backer flashing is generally limited to penetrations that are 24 inches wide or less." "NRCA recommends the cladding material and water-resistive barrier extend past cover the top edge of the flashing metal a minimum of 2 inches." Counterflashing: "Apron, step, cricket and backer flashings require some form of counterflashing to cover and protect their top edges from water intrusion." 53 Skylight flashings: "Skylights, in terms of roof flashing, are much the same as other vertical surface flashings, particularly chimney flashings."
