Install Asphalt Shingles on a Simple Roof Plane

A. Finished-Work Specification

Deliverable: one complete asphalt-shingle field on one unobstructed roof plane, installed from the first full course to the planned upper termination, with course exposure, offset pattern, and fastening matching the manufacturer's instructions and the Chapter 6 control lines, rake cuts finished to the required projection, any approved flashing in the plane integrated course-by-course, and a completed inspection record.

Bundle condition	Correct product, lot, color blend, damage, moisture, and storage condition confirmed before staging
Course exposure	Matches the manufacturer-specified exposure on every course, verified against control lines
Offset pattern	Matches the approved stair-step, rack, or other manufacturer method; no stacked joints
Fastening	Approved fastener type, count, and location on every shingle; heads seated flush without cutting the shingle surface
Rake cuts	Cut from the correct face with the approved tool; required projection maintained without edge-metal damage
Flashing integration	Any approved flashing in the plane integrated course-by-course, not inserted after the field is complete
Upper termination	Field stopped at the planned ridge-vent zone or cap-shingle preparation line
Housekeeping	Loose nails, release film, cutoffs, and packaging removed from drainage paths and the ground below

D. Required Project Sequence

1. Review shingle type, roof-slope limits, exposure, offset pattern, fastening zone, fastener quantity, wind requirements, sealing conditions, and temperature limitations. Record the approved exposure and fastener count from the manufacturer instructions on the field installation record before opening any bundle.
2. Confirm that starter strips, underlayment, edge metal, layout lines, and roof-safety systems are complete. Locate the signed records from Chapters 2, 3, 5, 6, and 7 for this roof plane. If any record is missing or shows an open item, stop this chapter and route the project back to the responsible chapter before continuing.
3. Inspect shingle bundles for correct product, lot, color blend, damage, moisture, and storage condition. Reject bundles that do not match the approved product or that show damage, moisture, or improper storage, and record any rejected bundles on the field installation record.
4. Distribute bundles within approved roof-load and access limits without placing them over unsupported or damaged areas. Stage bundles flat, clear of walkways established in Chapter 2, and away from marked weak areas from Chapter 1.
5. Blend shingles from the required number of bundles to reduce visible color concentration. Open and draw from at least four bundles at a time throughout the installation, not sequentially from single bundles.
6. Cut the first shingle to establish the required joint offset. Cut the starting piece to the dimension established in the Chapter 6 layout record so the first course's joint falls at the required offset from the starter-strip joint.
7. Position the first full course to the starter edge and horizontal control line. Align the course butt edge to the first horizontal control line from Chapter 6 and the shingle edge to the starter-strip overhang from Chapter 7.
8. Fasten each shingle through the manufacturer's designated fastening zone using approved roofing nails. Drive the specified fastener count at the specified locations within the fastening zone for every shingle in the course.
9. Seat nail heads flush without cutting the shingle surface or leaving raised heads. Check each fastener by hand or visually before covering it with the next course, and reset any overdriven or underdriven fastener immediately.
10. Continue the first course while maintaining edge alignment and joint spacing. Verify the running course against the horizontal control line at each shingle and correct drift before starting the next course.
11. Begin the next course with the required offset and maintain the specified exposure. Measure the offset distance from the layout record and verify exposure against the horizontal control line for that course.
12. Follow the approved stair-step, rack, or other installation pattern without stacking joints. Use the offset sequence established in the manufacturer instructions and the Chapter 6 layout record for every course.
13. Check alignment against horizontal and vertical control lines at regular intervals. Recheck every three to five courses against both the horizontal and vertical control lines rather than relying on the course below.
14. Correct drift before the error becomes concealed by additional courses. If a course has drifted from its control line, adjust exposure gradually over the following courses per the manufacturer's allowed adjustment range, and record the correction.
15. Cut rake shingles from the correct face using the approved cutting surface and tool. Cut from the manufacturer-specified face with the utility knife and hook blade or specified tool, supported on an approved cutting surface that protects the underlying course.
16. Maintain the required rake projection or trim line without damaging edge metal. Verify each cut against the rake projection established in the Chapter 6 layout record and the Chapter 3 edge-metal installation.
17. Integrate field shingles with any approved flashing encountered in the roof plane. Where step, headwall, apron, or penetration flashing is staged for this plane, install it course-by-course per the governing chapter's procedure as the field reaches that location; do not continue the field over an unintegrated flashing location.
18. Hand-seal shingles only where required by the manufacturer, cold-weather procedure, cut-tab condition, or repair detail. Apply the specified hand-seal adhesive at the manufacturer-required locations and press tabs into position without smearing sealant onto exposed surfaces.
19. Keep loose nails, release film, cutoffs, and packaging out of drainage paths and off the ground below. Clear debris from the plane at regular intervals during installation, not only at the end of the work period.
20. Stop the field at the planned upper termination, ridge-vent zone, or cap-shingle preparation line. Confirm the stopping point against the ventilation and ridge plan before installing the final course of this chapter's scope.
21. Inspect exposure, course alignment, joint offsets, nail placement, nail seating, edge cuts, tab damage, and sealing readiness. Walk the completed plane from approved positions and record findings on the inspection checklist below.
22. Replace damaged or improperly fastened shingles using the approved correction method. Lift surrounding tabs as needed, remove the defective shingle without damaging the underlayment, and install a matching replacement per the fastening schedule.
23. Clean the roof plane and document product, layout method, fastener schedule, weather, and inspection results. Photograph the completed field, attach photographs to the field installation record, and sign the inspection checklist.
