A coil roofing nailer is a pneumatic (or cordless) nail gun that feeds wire-collated nails from a round coil magazine, built specifically to drive short, large-head roofing nails fast on asphalt shingle work. For roofing there is effectively one choice: coil. Every production roofing nailer is coil-fed because a coil holds roughly 120 nails versus about 30 to 40 in a straight stick, and on a roof where you drive 4,000-plus nails a day, that is the difference between reloading once an hour and once every ten minutes. This guide covers coil vs stick, the PSI and depth settings that actually matter, the nail specs that keep you code-compliant, and how to dial the gun in so every nail sits flush.
Coil vs stick: why roofing nailers are always coil-fed
Roofing nailers are coil-fed because roofing is a high-volume, small-nail job, and coil magazines carry 3 to 4 times the fasteners of a stick. A coil roofing nailer winds about 120 wire-collated nails into a flat spiral that drops into a round canister. A stick (strip) nailer holds 30 to 40 nails in a straight cartridge. There are no serious stick-fed roofing nailers on the market, so for shingles the practical question is never coil vs stick, it is which coil nailer.
The distinction still matters because “coil nailer” is a broader category. Coil siding and framing nailers also exist and take longer, thinner nails. A roofing-specific coil nailer is tuned for short 3/4-inch to 1-3/4-inch nails with wide heads, and it typically fires at a 15-degree magazine angle. Do not buy a coil siding nailer for shingle work: the nail range and head size are wrong.
| Feature | Coil roofing nailer | Stick (strip) nailer |
|---|---|---|
| Magazine capacity | ~120 nails | 30 to 40 nails |
| Reload frequency (per 4,000 nails) | ~33 reloads | ~100 to 130 reloads |
| Collation | Wire, wound coil | Paper or plastic strip |
| Magazine angle | Typically 15 degrees | Straight or angled |
| Right tool for shingles | Yes | Not made for it |
What PSI should a roofing nailer run at?
Most coil roofing nailers operate between 70 and 120 PSI, and a good starting point is about 90 to 95 PSI at the tool. Fire a test nail or two into scrap decking, then adjust up or down based on how the head sits. Higher pressure drives deeper, lower pressure drives shallower. The goal is a nail set flush with the shingle surface, not sunk into it and not standing proud.
Compressor output and hose length change what reaches the gun. Many roofers set the compressor regulator around 100 PSI and let the tank cycle higher, roughly 110 to 130 PSI, so air stays constant as multiple guns fire. Long hose runs and cold mornings drop delivered pressure, so re-check your test nail after any change in hose length, temperature, or when a second nailer comes onto the same compressor.
Depth setting and overdrive: the flush-nail rule
Set depth so the nail head sits flush with the shingle: not overdriven (cutting into or through the mat) and not underdriven (standing above the surface). This is the single most consequential setting on a coil roofing nailer, because an incorrect drive depth repeats on every fastener. On a typical residential roof with roughly 2,000 shingles at 4 nails each, that is 8,000 chances to get it wrong the same way.
Most quality nailers have a tool-mounted depth-of-drive adjuster (a knurled wheel or shoe) so you can fine-tune without touching the compressor. Use the depth adjuster for small corrections and the PSI regulator for larger ones. An overdriven nail breaks the shingle’s seal around the head and can cut the mat, which is a documented path to blow-offs and voided wind warranties. An underdriven or “proud” nail leaves a bump that telegraphs through the course above and can back out over time.
How to dial in a coil roofing nailer (test-nail procedure)
- Set the regulator to about 90 PSI and the depth adjuster to the middle of its range.
- Fire 2 to 3 nails into scrap shingle over the same decking you will roof (plywood or OSB).
- Check the heads: flush and snug is the target.
- If overdriven (sunk, mat torn), drop 5 to 10 PSI or back off the depth adjuster, then retest.
- If underdriven (standing proud), add 5 to 10 PSI or increase depth, then retest.
- Re-test after any change in hose length, air temperature, decking thickness, or when adding a second gun to the compressor.
| Nail result | What it means | Fix |
|---|---|---|
| Flush, head snug on shingle | Correct drive | Keep firing, spot-check hourly |
| Sunk below surface, mat cut | Overdriven | Lower PSI 5 to 10 or reduce depth |
| Head standing proud | Underdriven | Raise PSI 5 to 10 or increase depth |
| Nail tilted or angled | Gun not held square | Hold the nose flat, retest |
Nail specs and code: what your coil nailer must fire
A roofing coil nailer must fire nails that meet code, not just whatever fits the magazine. Under IRC R905.2.5, asphalt shingle fasteners are corrosion-resistant roofing nails, minimum 12-gauge shank with a head at least 3/8 inch in diameter, long enough to penetrate through the roofing and at least 3/4 inch into the deck (or fully through decking thinner than 3/4 inch). Coil roofing nailers commonly run 11-gauge (0.120-inch) wire-collated nails from 3/4 inch to 1-3/4 inch, which covers new shingles over most decks and typical re-roof buildups.
Length is chosen by total thickness. For a single layer of asphalt shingles on 3/4-inch decking, 1-1/4 inch is a common pick; go longer (1-1/2 to 1-3/4 inch) over an existing layer or thicker buildup so the shank still bites 3/4 inch into the deck. For the full breakdown of gauge, head size, and length by application, see our guide to roofing nail sizes, types, and code requirements.
How many nails: 4 vs 6 and where the nailer fits
The nailer sets each fastener, but code sets how many per shingle. The IRC baseline is 4 nails per strip shingle; high-wind areas with a design wind speed over 90 mph require 6 nails per strip. Coastal and high-wind zones in states like Texas, South Carolina, North Carolina, Florida, and Alabama frequently exceed 110 mph design speeds, where a 4-nail pattern is a code violation. Your coil nailer makes hitting 6 nails fast, but placement still has to land in the manufacturer’s nail zone, so speed does not replace aiming at the line.
Pneumatic vs cordless coil roofing nailers
Pneumatic coil roofing nailers remain the production standard: light in the hand, cheap per tool, and fast, but tethered to a compressor and hose. Cordless coil roofing nailers, such as Milwaukee’s M18 FUEL 15-degree model, remove the hose and compressor entirely, which speeds setup on small jobs, steep pitches, and repairs where dragging air is a hassle.
The trade-offs are weight, cost, and sustained speed. Cordless guns are heavier at the nose and cost more up front, and a high-volume crew driving thousands of nails an hour still tends to favor pneumatics for pace and all-day endurance. Many crews carry a cordless for tear-off patches, ridge, and detail work and run pneumatics for the field.
| Factor | Pneumatic coil nailer | Cordless coil nailer |
|---|---|---|
| Setup | Compressor plus hose | Grab and go, battery only |
| Weight | Lighter at the nose | Heavier (motor plus battery) |
| Up-front cost | Lower per gun | Higher |
| Best for | High-volume field nailing | Repairs, ridge, steep or remote work |
Proven coil roofing nailer models
A handful of coil roofing nailers show up on production crews year after year for consistent drive depth and easy maintenance. The Bostitch RN46 is one of the most widely used in the trade. The Metabo HPT NV45AB2 is a long-running favorite on high-volume crews. Senco’s RoofPro line is trusted for smooth operation on asphalt shingles and felt. For hoseless work, the Milwaukee M18 FUEL 15-degree cordless coil roofing nailer runs on the M18 battery platform.
Whichever you pick, the specs to confirm are the same: 15-degree magazine, roughly 120-nail coil capacity, an 11-gauge nail range of about 3/4 inch to 1-3/4 inch, a tool-side depth-of-drive adjuster, and selectable bump-fire versus sequential trigger. The depth adjuster and trigger mode matter more day to day than brand badge.
Maintenance and safe operation
A coil roofing nailer needs a few drops of pneumatic tool oil in the air inlet at the start of each day (unless the maker specifies oil-free), plus a clean magazine so the coil feeds without jams. Blow out grit, keep the driver channel clear, and check the no-mar nose and depth shoe for wear. Neglected oiling is the top cause of soft or inconsistent drive later in a shift.
Run the gun in sequential trigger mode where accurate single placement matters, and reserve bump-fire for open field runs. Keep the muzzle pointed at the deck, never bump-fire while repositioning, and set the compressor pressure before you climb. Working on a roof adds fall risk on top of tool risk, so pair correct nailer technique with proper tie-off; see our roof safety guide for OSHA harness and anchor rules.

If nails have already backed out on an existing roof, our guide to nail pops on shingles explains why drive depth is usually the culprit.
Frequently asked questions
What PSI should I set a coil roofing nailer to? Start around 90 to 95 PSI at the tool and adjust from a test nail. The full range is roughly 70 to 120 PSI. Aim for a head set flush with the shingle. Raise pressure if nails stand proud, lower it if they sink and cut the mat. Re-check after hose, temperature, or decking changes.
Is a coil nailer better than a stick nailer for roofing? For roofing, yes. A coil roofing nailer holds about 120 nails versus 30 to 40 in a stick, so you reload far less on a job that uses 4,000-plus nails a day. There are no production stick-fed roofing nailers, so coil is the standard for shingle work.
What size nails does a coil roofing nailer use? Most fire 11-gauge (0.120-inch) wire-collated roofing nails from 3/4 inch to 1-3/4 inch, with heads at least 3/8 inch. IRC R905.2.5 requires the nail to reach at least 3/4 inch into the deck, so length is chosen by total roof thickness: about 1-1/4 inch for a single layer on 3/4-inch decking, longer over buildup.
How deep should a roofing nail be driven? Flush with the shingle surface: not overdriven (sunk in or cutting the mat) and not underdriven (standing proud). Overdriving breaks the seal around the head and is a known cause of shingle blow-offs and voided wind warranties. Use the tool depth adjuster for fine tuning and PSI for larger changes.
How many nails per shingle does code require? The IRC baseline is 4 nails per strip shingle, and 6 nails per strip in high-wind areas where the design wind speed exceeds 90 mph. Coastal zones above 110 mph in states like Florida, Texas, and the Carolinas require 6 nails, where a 4-nail pattern is a violation.
Pneumatic or cordless coil roofing nailer? Pneumatics are lighter, cheaper per gun, and faster for high-volume field nailing, but need a compressor and hose. Cordless models like the Milwaukee M18 FUEL skip the hose for repairs, ridge, and steep or remote work, at the cost of more weight and higher price. Many crews run both.
