SeeFastening Pattern and Physical Dimensions - Detail "B" attached. Flashing: Roof planes that butt against vertical walls shall be step flashed with 10" long metal shingles which are 2" wider than the exposed face of the roofing shingles. Place the first flashing unit over the end of the starter strip and position it so that the tab of the end shingle in the first course covers it completely. Secure the horizontal arm to_the roof with two approved roofing nails. Do not nail flashing to the wall; settling of the roof could damage the seal. Apply the first course of shingles up to the wall. Position the second step flashing strip over the end shingle in the first course 5 ipches up from the butt so that the tab of the end shingle in the second course covers it completely. Fasten the horizontal arm to the roof. The second course of shingles follows, the end is flashed as in the preceding courses and so on to the top of the intersection. Bring siding or other wall treatment down over the vertical sections of the step flashing to serve as cap flashing. Wall treatment or cap flashing shall terminate a minimum of Y above the roof line. Page 9 of 20 FrankLuloaga, Roofing Plans Examiner Product Control Division Froduct Uontrol NO.: Y/-uJl /.uL Vertical sidewalls shall be flashed. Apply shingles up the roof until a course must be trimmed to fit at the base of the vertical wall. Adjust the exposure slightly in the previous two courses so that the'last course is at least 8 inches wide. Apply a continuous piece of metal flashing over the last course of shingles by embedding it in approved flashing cement and nailing it to the roof. The metal flashing strip shall be bent to extend at least 5 inches up the vertical wall and at least 4 inches onto the last shingle course. Do not nail the strip to the wall. Apply an additional row of shingles over the metal flashing strip, trimmed to the width of the strip. Bring siding down over the vertical flashing to serve as cap flashing. Wall treatment or cap flashing shall terminate a minimum of 3" above the roof line. Do not nail siding into the vertical flashing. If the vertical front wall meets a sidewall, as in dormer construction, cut flashing so that it extends at least 7 inches around the corner. Continue up the sidewall with step flashing as detailed above. Soil Stacks and Vent Pipes: Apply shingles up to the vent pipe. Cut a hole in a shingle to go over the pipe and set the shingle in ASTM D 4586 flashing cement. A preformed flashing flange that fits snugly over the pipe is then placed over the shingle and vent pipe and set in approved flashing cement. Place the flange over the pipe to lay flat on the roof. After the flashing is in place, resume shingle application. Cut shingles in successive courses to fit around the pipe and embed them in approved flashing cement where they overlap the flange. Avoid excessive use of cement as it may cause blistering. Do not drive fasteners close to the pipe. The lower part of the flange shall overlap the lower shingles and the side and upper shingles shall overlap the Flange. For ventilator and exhaust stacks, follow the same procedure, but bring the shingles up to the pipe from both sides and betid the flange over the ridge to lie in both roof planes, overlapping the roof shingles at all points. Ridge shingles are then .positioned to cover the flange. Embed the ridge shingles in approved flashing cement where they overlap the flange.
