Why Proper Nailing is Important

Before we dig into the how-to, let’s understand why proper nailing is so crucial. Misplaced or insufficient nailing can lead to several issues, including:
- Wind Damage: Incorrectly nailed shingles may get blown away during heavy winds.
- Leaks: Poor nailing can allow water to seep through your roof, causing leaks and water damage.
- Warranty Issues: Manufacturer warranties often require shingles to be installed according to specific guidelines. Incorrect nailing can void your warranty.
Tools and Materials Needed
Before you get started, make sure you have all of the supplies that you need!
⚒️ Tools:
- Hammer or pneumatic roofing nailer
- Utility knife
- Chalk line
- Ladder
- Safety harness
- Work gloves
- Measuring tape
🧱 Materials:
- Asphalt shingles
- Roofing nails (galvanized, 1¼ to 2 inches long)
- Underlayment
- Drip edge
- Starter strip shingles
Preparing the Roof
Before you begin your roofing project, make sure that your roof is fully prepared.
🔎 Inspection
Before you start, inspect your roof deck for any damage. Replace any rotted or warped plywood. A clean, solid surface is essential for properly installing shingles.
👷🏾 Install Underlayment and Drip Edge
Lay down the underlayment to act as a moisture barrier. Install the drip edge along the eaves to direct water away from the fascia board.
A 4 Step Guide to Nailing Asphalt Shingles

Let’s get you some new asphalt shingles! Follow these installation instructions, for great results.
Step 1: Laying the Starter Strip
The starter strip is the first layer of shingles at the edge of the roof. It helps prevent water from infiltrating the roof decking.
- Measure and Cut: Cut the tabs off a shingle to create a starter strip.
- Place and Nail: Place the starter strip along the eave, ensuring it overhangs the drip edge by about ¼ to ¾ inch. Nail the starter strip at 6-inch intervals, placing nails about 1 inch above the shingle’s edge.
Step 2: First Course of Shingles
- Align: Place the first full shingle over the starter strip, aligning it with the bottom edge of the roof.
- Nail: Use four nails per shingle, driving them 1 inch above each cutout and 1 inch from each edge. Ensure the nails penetrate through the shingle and into the roof deck.
Step 3: Subsequent Courses
- Stagger Shingles: Start the second row with a half shingle to stagger the seams.
- Chalk Line: Use a chalk line to ensure straight rows.
- Nail: Position the next shingle over the previous row, covering the nail heads of the shingle below. Continue nailing 1 inch above the cutouts and 1 inch in from each edge.
Step 4: Cap Shingles
Cap shingles are used at the ridge and hips of the roof. Here’s how to install them:
- Cut Shingles: Cut regular shingles into three tabs.
- Position: Place the first cap shingle over the ridge, extending equally on both sides.
- Nail: Nail each cap shingle with two nails, one on either side, about 1 inch from the edges. Overlap each subsequent cap shingle to cover the nails of the previous one.
Nailing Tips and Best Practices
- Nail Placement: Always nail shingles in the designated nail zone, typically marked on the shingle. This ensures optimal holding power.
- Nail Depth: Nails should be driven flush with the shingle surface, not overdriven or underdriven. The head should be flat against the shingle without cutting into it.
- Nail Type: Use galvanized or stainless steel roofing nails to prevent rust. Nail length should be sufficient to penetrate the shingle and at least ¾ inch into the roof deck or all the way through the decking if it is less than ¾ inch thick.
- Weather Conditions: Avoid installing shingles in extremely cold or hot weather. Cold can make shingles brittle, and excessive heat can cause them to stick together.
Common Mistakes to Avoid
- Incorrect Nail Placement: Placing nails too high or too low can compromise the shingle’s integrity. Always follow manufacturer guidelines.
- Insufficient Nailing: Using fewer nails than recommended can lead to shingles being blown off in high winds.
- Improper Overlap: Ensure each shingle course properly overlaps the nails of the shingles below it to prevent leaks.
Troubleshooting Common Issues
Shingle Lift
Sometimes, you might notice that some shingles are lifting. This could be due to:
- Poor Adhesion: Inadequate pressure during installation can prevent shingles from adhering properly. Ensure each shingle is pressed down firmly after nailing.
- Nail Pops: This happens when nails push back out of the roof deck. Check for any high nails and reseat them with proper pressure.
Leaks
If you notice leaks:
- Inspect Nail Placement: Ensure no nails are exposed. Exposed nails should be covered with roofing sealant.
- Check Valleys and Flashing: These are common leak points. Make sure they are properly installed and sealed.
Maintaining Your Shingle Roof

Even your roofing shingles need a little TLC! But you don’t need to call on your local roofing contractors for that. Instead, follow these simple maintenance tips to get the most out of your roofing system.
Regular Inspections:
Conduct regular inspections of your roof, especially after severe weather. Look for signs of damage, loose shingles, or exposed nails.
Clean Gutters:
Keep your gutters clean to prevent water backup, which can damage shingles and the roof deck.
Remove Debris:
Clear debris like leaves and branches from your roof, as they can trap moisture and cause rot.
Trim Overhanging Branches:
Trim branches that hang over your roof to prevent them from scraping shingles or falling and causing damage.
