Now, let’s break down the actual installation process:
Step 1: Install Starter Strip
- Use pre-cut starter strips or cut the tabs off shingles.
- Nail the starter strip along the eaves with an overhang of about 1/4 inch beyond the drip edge.
- This helps prevent water from seeping under the shingles.
Step 2: Lay the First Course
- Place the first shingle directly on top of the starter strip.
- Nail each shingle with four nails (six in high-wind areas).
- Make sure nails are driven flat but not cutting into the shingle.
Step 3: Continue with Staggered Pattern
- Cut 6 inches off the first shingle of the second row.
- Place it above the first course, lining it up with the chalk line.
- This staggered pattern prevents water infiltration at seams.
Step 4: Work Up the Roof
- Continue laying shingles row by row, overlapping as you go.
- Keep checking alignment with chalk lines.
- Always nail in the designated nailing strip.
Step 5: Flashing Around Obstacles
- For chimneys, skylights, and vents, install step flashing.
- Place metal flashing pieces with each row of shingles around the obstacle.
- Seal with roofing cement for added protection.
Step 6: Ridge Cap Installation
- Once you reach the roof peak, install ridge cap shingles.
- Bend them over the ridge and nail each side, overlapping as you go.
- This completes the roof and provides ventilation at the ridge.
