Cedar roof shingles are a classic and aesthetically pleasing choice for roofing. Properly installing cedar shingles requires attention to detail, and one crucial aspect is nailing. In this guide, we will provide precise and clear instructions on how to correctly nail cedar roof shingles.

Tools and Materials You’ll Need

1. Cedar Shingles: Ensure your cedar shingles are of high quality and free from any defects or splits.
2. Roofing Nails: Opt for stainless steel or hot-dipped galvanized roofing nails. They should be long enough to penetrate through the shingle, underlayment, and into the roof deck.
3. Nail Gun or Hammer: You can use either a pneumatic nail gun or a hammer. Nail guns are faster, but hammers work well for manual control.
4. Safety Gear: Wear safety glasses and gloves to protect your eyes and hands.

Step-by-Step Guide for Nailing Cedar Roof Shingles

1. Prepare the Roof Surface:
Ensure the roof deck is clean, dry, and free from any debris. Install an underlayment, such as roofing felt, to provide an additional moisture barrier.

2. Position the Shingle:
Start at the bottom of the roof and work your way up. Position the first cedar shingle with the thicker butt end facing down, overhanging the roof’s edge according to your desired exposure (usually 4 to 6 inches).

3. Align the Shingle:
Align the first shingle with the layout marks on the roof deck to ensure it is straight and square. Use a chalk line or a straight edge as a guide.

4. Nailing:
For each cedar shingle, follow these nailing guidelines:

• Space nails approximately 1 inch from the edge of the shingle.
• Place the nails 1 inch above the exposure line (the area of the shingle that is exposed to the weather).
• Angle the nails slightly downward, around 15-20 degrees, to help prevent water infiltration.

5. Nail Placement:
For best results, use two nails per shingle, positioned roughly 2 inches apart horizontally. Avoid nailing near the edges of the shingle to prevent splitting.

6. Nail Depth:
Drive the nails flush with the surface of the cedar shingle. Do not overdrive or underdrive them, as this can compromise the shingle’s integrity.

7. Stagger the Joints:
When installing subsequent rows of shingles, stagger the joints to create a watertight barrier. A common practice is a 1/8-inch overlap.

8. Trim Shingles:
As you reach the roof’s peak, you may need to trim shingles to fit. Use a saw or utility knife to make precise cuts.

9. Flashing and Ridge Cap:
Install flashing and a ridge cap to seal the roof’s peak properly.
