Review the building plans for locations of roof penetrations. Verify that plumbing stacks are extended through roof and are secured in-place. 2. Review shingle and roof vent manufacturer s installation instructions with the Construction Coordinator. Manufacturer s instructions take precedent. 3. Broom clean the roof sheathing if required to remove debris. NOTE: Use extreme caution when walking on roof sheathing that is damp or has construction debris on it. Ch 9-1
9.1 LEAK BARRIER (ICE AND WATER SHIELD) 1. Apply underlayment in fair weather when the air, roof deck and membrane are at temperatures of 40 degrees or higher. 2. Underlayment should be installed over the metal drip edge at the eave; ensure metal drip edge is nailed properly. 3. Underlayment should be installed under the drip edge at the rake. 4. Unroll underlayment and cut into 10-20 lengths, depending on the length of the roof. Allow to relax for 3-5 minutes before installing. 5. Reroll each portion. Remove the first two feet of the release backer and press the product into place. 6. While supporting the roll with one hand, remove the release backer with the other hand and press or roll into place. 7. Overlap at least 6 inches at the end laps. 9.2 SHINGLE UNDERLAYMENT 1. Starting along the low edge of the roof, roll out shingle underlayment from edge to edge making sure to keep felt smooth and free from wrinkles. 2. Cap nail the underlayment to the sheathing using pneumatic staplers. 3. Fasten underlayment using plastic cap staples. Fasten side (horizontal lap) and end laps (vertical lap) 12 inches on center (6 inches for high wind). Fasten in field of the roll with two staggered rows of fasteners spaced 24 inches on center (use 12 inch on center for high wind). 4. Overlap 3 at side lap (horizontal lap) over preceding course. Use the printed 3 selvedge line to help align the overlap. 5. Continue installing underlayment to the roof peak lapping the last row over the peak to provide rain protection to the interior. 9.3 INSTALLING GUTTER APRON AND GABLE D-EDGE 1. Install gutter apron along the lower (eave) edges of the roof. Fasten with roofing nails at 8 on center. Gutter apron must be installed below the roofing felt to allow for water to drain off roof. Ch 9-2
2. Cut the apron with tin snips and overlap ends 3 to continue along the roof edge making sure the apron does not extend beyond the roof edges. 3. Install D-Edge along the gable end of the roof similar to the gutter apron. Install the flashing over the felt. 9.4 INSTALLING SHINGLES 1. A chalk line should be snapped across the length of the roof at a distance of one shingle width up from the gutter edge less 3 / 8 so shingles will extend over the gutter edge of the roof. 2. Install the starter course of shingles with the tar strip located near the lower edge of the roof. 3. Starting at the left end of the gable roof, cut 6 from a starter shingle and align the edge flush with the D-Edge with the top edge on the chalk line. Secure with four (4) roofing nails installed just above the tar strip. 4. Install successive starter shingles across the roof, trimming the last shingle flush with the D-Edge. 5. Starting at the left edge install a full length shingle over the starter and secure using four (4) nails installed above the tar strip where noted by the manufacturer. 6. Start the second course with a full shingle minus 6, saving the 6 section for use at the 5 th course. 7. Start the third course with a full shingle minus 11, saving the 11 section for use at the 4 th course. 8. On the fourth course begin with the 11 shingle cut from the third course. 9. At the fifth course begin with the 6 shingle cut from the second course. 10. The sixth course starts over with a full shingle, repeating the process to the roof peak. 11. Chalk lines should be snapped every second course to keep shingles in a straight line across the roof. This line is used for placement of the top edge of the shingle and is always measured from the bottom edge of the roof. 12. At the roof ridge, cut away the roofing felt and shingle to the opening ends and edges. 13. Where shingles abut a parallel wall, step flashing must be installed as each shingle is installed. Alternate step flashings and shingles as you work up the roof, nailing only in the top edge of the step flashing to avoid water leakage. If air barrier has been installed on the wall make sure the flashing is installed behind the barrier. Ch 9-3
Figure 9-1 9.5 RIDGE VENT AND CAP 1. Review the manufacturer s installation instructions on the box prior to starting. 2. Install cap shingles on first and last 14 of peak over a starter shingle that has the bottom 5 5 / 8 removed. 3. Install the vent over the apex of the roof starting 10 from the edge of the roof. Secure with 3 roofing nails in the nailing holes provided. 4. Continue installing vent pieces butting the previous piece along the vent opening and trim the last piece to end 10 from the roof edge. Ch 9-4
5. Cap the roof vent using capping shingles provided. The cap shingle is installed over the vent and nailed through the tar strip. Overlap succeeding layers similar to the roof shingles. 6. Cover the last two (2) nails with roofing tar to prevent leakage. Figure 9 2 Ridge shingles have a centering notch and two side-alignment notches to help ensure alignment. Figure 9 3 Ch 9-5
Apply a full cap shingle over a starter piece flush with the bottom and side edges of the starter shingle. Figure 9 4 Use laying notches to center shingles on ridges and to locate the correct exposure. Ch 9-6
