Roofing Nailer for Shingles: The Easiest Way to Get the Job Done

Hey everyone, Jack Shaffer here from Nailerguy! Ever looked up at a steep roof and thought, “No way can I shingle that”? I get it. It looks daunting. But with the right tool – specifically, a roofing nailer – and a little guidance, you can tackle this project with confidence. Forget the hammer-and-nail marathon; a roofing nailer is a game-changer, making the process surprisingly straightforward and speedy. If you’ve been putting off that re-roofing job or a small shed project, this guide is for you. We’ll break down exactly how to use a roofing nailer for shingles the easiest way possible, ensuring a durable and attractive finish without the usual headaches.

Why a Roofing Nailer is Your Shingle-Slinging Secret Weapon

Before we dive into how, let’s talk about why a roofing nailer is the easiest way. Trying to nail shingles by hand, especially on a large roof, is incredibly time-consuming and physically demanding. Each shingle requires multiple nails, and imagine doing that hundreds of times with a hammer! It’s a recipe for sore arms, missed nails, and blisters.

A roofing nailer, on the other hand, drives nails quickly and consistently. It’s designed specifically for this job, meaning it handles the tough roofing nails with ease and helps you maintain the correct depth and placement every time. This consistency is key to a watertight and long-lasting roof. Plus, it’s much faster, saving you precious time and energy.

Choosing the Right Roofing Nailer for Shingles

Not all nailers are created equal, and for shingles, you need a specific type. The easiest way to start is by picking the right tool for the job.

Types of Roofing Nailers

There are a few main types, but for shingle installation, you’ll primarily encounter these:

Pneumatic Roofing Nailers: These are the most common and powerful. They connect to an air compressor via a hose. They’re reliable, durable, and offer consistent performance.
Cordless (Battery-Powered) Roofing Nailers: These offer portability and convenience, as you don’t need an air compressor or hose. Newer models are very powerful, but they can be more expensive and might require more batteries for a large job.
Gas-Powered Roofing Nailers: These use fuel cells and batteries. They are also portable but can sometimes have a stronger exhaust smell and a slightly less consistent feel than pneumatic models.

Adjustable Depth Control: This is CRUCIAL. You need to set the nail depth so it’s flush with the shingle surface but doesn’t overdrive (burying the nail head too deep, which can damage the shingle) or underdrive (leaving the nail head proud, which can cause leaks).
Nail Compatibility: Ensure the nailer accepts the correct type and size of roofing nails. Most roofing nailers use 1-inch to 1 ¼-inch galvanized roofing nails, often collated at a 15-degree angle.
Lightweight and Ergonomic Design: You’ll be holding this tool for extended periods. A lighter nailer with a comfortable grip reduces fatigue.
Rafter Hook: A hook allows you to hang the nailer on a rafter when you need to reposition or take a break, keeping it out of the way and off the ground.

Inspect the Roof Deck: Ensure the plywood or OSB roof deck is solid, dry, and free of any damage. Replace any rotten or warped sections.
Install Drip Edge: Attach metal drip edge along the eaves (bottom edges) and rakes (sloping side edges) of the roof. This directs water away from the fascia and into the gutters.
Roll Out Underlayment: Starting at the eaves, roll out roofing felt or synthetic underlayment up the roof. Overlap subsequent layers by at least 4-6 inches, ensuring water flows down and away. Secure it according to the manufacturer’s instructions, usually with staples or cap nails. For a watertight seal, refer to guidelines like those from the Building Science Corporation on roof drainage principles.
Mark Chalk Lines: Using your measuring tape and chalk line, create horizontal chalk lines on the underlayment. These lines guide your shingle placement, ensuring they are straight and evenly spaced. The spacing will depend on your specific shingle type, so consult the manufacturer’s guide. Typically, this is around 5-6 inches from the top of the previous shingle row.

Connect (Pneumatic): If using a pneumatic nailer, connect your air hose to the compressor. Set the compressor to the recommended PSI for your nailer (usually between 70-100 PSI). Test the connection for leaks.
Load Nails: Open the nailer’s magazine and load the 15-degree collated roofing nails. Ensure they are seated correctly against the feed mechanism.
Adjust Depth Setting: This is the most critical adjustment.
Grab a scrap piece of shingle and underlayment.
Set the depth adjustment (often a dial or lever on the nailer) to a moderate setting.
Fire a nail into the scrap material.
Check the nail head. You want it to be slightly below the shingle surface, but not so deep that it tears through the asphalt or damages the mat. The nail head should be visible, but the nail shank should be fully embedded.
Adjust the depth as needed, firing and checking until you achieve perfect depth. It’s better to err slightly proud than to overdrive, as overdriving damages the shingle.
Test Fire: Fire a few nails into the scrap material again to confirm the depth setting is correct and the nailer is firing consistently.

Step 3: Nailing the First Row (Starter Shingles) — The Easiest Technique

The first row of shingles, called the starter course, is vital for sealing the edge of your roof.

First Shingle: Place the first starter shingle against the eaves, aligning its starting edge with the drip edge. Some starter shingles have an adhesive strip; ensure this is facing up (towards where the next shingle will go). If using standard shingles as starter, ensure the cutouts face up and away from the edge.
Nail Placement:
Nail the starter shingle according to the manufacturer’s specifications. Typically, this involves four nails per shingle.
The nails are driven in a straight line, approximately 1 inch from the edge of the shingle and at least 6 inches from the side edge.
Crucially, when nailing the starter edge, ensure the nails are placed above the seal strip of the shingle, but below the cutout line of the next shingle. This provides anchorage without compromising the seal.
Hold the nailer perpendicular to the roof surface.
Subsequent Shingles: Overlap the starter shingles slightly as you move along the eaves. The goal is a continuous, sealed edge.

First Course of Field Shingles: Lay your first full shingle course down, aligning the bottom edge with the starter course. The cutouts on the shingle should be placed directly over the nails of the starter course.
Nail Placement: This is the most important part for structural integrity and weatherproofing.
Most shingles require four nails per shingle. Some windswept areas may require six. ALWAYS check the manufacturer’s guidelines.
The nails should be placed in a straight line across the shingle. This line is typically 6 inches from the side edge of the shingle and then spaced out along the shingle’s length. The key is to align the second, third, and fourth nails along a straight line that runs parallel to the shingle’s edge.
The nails should be driven into the “nailing strip” – a thicker area marked on the back of the shingle for this purpose.
The nails should be about 5 ½ to 6 inches up from the bottom edge of the shingle (or just above the seal strip of the shingle below it).
Crucially, ensure the nails are NOT driven into the cutouts of the shingle below. They should land on the solid part of the shingle to create a proper seal. This is why the chalk lines are so important.
For very high wind areas, some manufacturers recommend a second row of nails, placed higher up but still within the acceptable nailing zone.

The Rule of Thumb: For standard 3-tab shingles, stagger the end joints of subsequent rows by at least 6 inches from the row below. This means the start of a new row won’t line up with the start of the row beneath it.
Architectural Shingles: Many modern architectural shingles come with specific patterns or offset recommendations. Follow these precisely. Generally, you’ll need to cut the first shingle of an offset row to create a shorter starting piece, then continue with full shingles. This creates a more random, visually appealing pattern and reinforces the roof.
How to Stagger:
Row 1 (Starter): Full width.
Row 2 (Field): Start with a full shingle.
Row 3 (Field): Usually starts with a shingle cut by about 1/6th of its width (approx. 5-6 inches for a 12-inch shingle).
Row 4 (Field): Starts with a shingle cut by about 2/6ths of its width (approx. 10-11 inches).
Row 5 (Field): Starts with a full shingle again, repeating the pattern.

Pipe Boots and Vents: Cut shingles to fit around vent pipes. Lay the shingle that would normally go under the pipe, then cut another shingle to go over it, overlapping the edges. Apply roofing sealant under the tabs of the shingle covering the pipe and around the pipe itself for a watertight seal. The nails should go into the solid part of the shingle, not into the cutouts.
Valleys: Valleys are where two roof slopes meet. There are two common methods: woven valleys and closed-cut valleys.
Woven Valleys: Shingles from one side are run through the valley and woven over shingles from the other side. This is common for asphalt shingles.
Closed-Cut Valleys: Shingles meet at the center of the valley. One side’s shingles are laid first, then the adjacent side’s shingles are laid to meet them, with the excess cut off at a sharp angle along the valley’s edge. A metal valley flashing is often installed underneath.
Nailing in valleys requires care. Avoid nailing through the middle of the valley material where water flows. Nails should be placed a safe distance from the water channel, following manufacturer guidelines.
Chimneys and Skylights: These require flashing details specific to the material and the roof. Install step flashing where the shingle roof meets the vertical surface of the chimney. Always use appropriate sealants.

Ridge Cap Shingles: These are special shingles designed for the peak of the roof where two slopes meet. Cut standard shingles into thirds to create ridge cap pieces, or use pre-made ridge cap shingles.
Installation: Lay ridge cap shingles, overlapping each other and covering the nails of the previous course. They should be nailed into both sides of the ridge. The nails on one side of the ridge cap shingle should NOT be visible on the other side. For example, if you are installing on the left side of the ridge, your nails will go on the left side of the ridge cap shingle, and they won’t be visible on the right side.
Sealant: Apply roofing sealant under the exposed edges of the last row of shingles at the eaves and under the edges of the ridge cap shingles to prevent wind uplift.
* Final Inspection: Walk the roof (safely!) and visually inspect all shingles and flashing. Check that all nail heads are properly set. If any are proud, gently tap them down with a hammer and a block of wood to avoid
