A roofing nailer lives or dies on a few details. This page covers air-powered coil nailers. Check the nail range first, since coil roofing work needs longer nails. Then look at weight, because you hold the tool for hours. Depth control, a shingle guide and a carbide nose also matter on asphalt shingles. We put 12 products on one spec sheet so you can compare these points side by side. Where a maker does not publish a spec, we say so.

We reviewed 25 roofing nailers and kept only the 12 that pass every check below. Those are ranked by a Best Score built from spec fit for this job, sales rank.
These reviews are based on specifications and listing information. They cover the top five products in our ranking.
Bostitch RN46 pairs a carbide nose with a shingle guide
The RN46 is a pneumatic coil roofing nailer that drives nails from 0.75 to 1.75 in. That covers the longer nail sizes most shingle jobs call for. It runs on 70 to 120 PSI, so a standard compressor can feed it. It holds 120 nails and takes 15° collated coils, the angle used by most models that list one.
Shingle work is about speed and clean nail heads. The nosepiece has carbide inserts, which resist wear from repeated contact. A shingle guide helps with spacing, and the depth guide adjusts without tools per the spec sheet. The listing also names a zero nail lockout, which stops dry firing and signals when to reload the magazine.
Weight is 5.8 lb. It is the second heaviest of the nine models that list weight, so it is not the lightest pick for overhead or all-day use. At 13.38 in, it is also the longest of the eight models that list length. That may matter in tight spots near ridges or eaves.
VerdictThe RN46 leads our ranking by combining a carbide nose, shingle guide and depth adjustment, at the cost of extra weight and length.
Metabo HPT NV45AB2 fires fast in a short body
The NV45AB2 ranks second on our list. Its firing rate is 10 nails/sec, the highest among the four models that list one. For roofers, that means the tool can keep up with a fast crew on open decks. It works at 70 to 120 PSI and holds 120 nails in a 16° magazine.
Length is the other standout. At 9.84 in, it is the shortest of the eight models that list tool length. A short body helps in tight spots near valleys and ridges. Weight is 5.7 lb, which is mid-pack among the nine that list it. The nailer drives 0.875 to 1.75 in nails and has tool-free depth adjustment.
Some roofing extras are missing from the spec sheet. The data shows no shingle guide or carbide nose. The trigger switches between sequential and bump modes, so one tool can handle careful and fast work. The 16° angle matters: buy 16° coil nails, not the 15° type most other models here use. It carries a 5-year warranty.
VerdictThe NV45AB2 suits roofers who value speed and a short body more than built-in shingle spacing.
Dotool CN45C covers the roofing basics at 5.6 lb
Start with weight, since long roofing days wear on the arms. The CN45C is 5.6 lb, below the 5.8 lb Bostitch and close to the other light models here. It has an aluminum housing and a 15° coil design that takes nails from 0.75 to 1.75 in. The listing calls it well balanced.
Roof-specific controls are covered. The spec sheet lists tool-free depth adjustment and a shingle guide, which help set nail depth and course spacing. It runs at 70 to 120 PSI and holds 120 nails in a side-loading magazine. The listing adds a tool-free jam release and a magnetic nail holder that aligns nails during loading.
Gaps are worth noting. The data shows no carbide nose, firing rate, tool length or warranty for this model. The listing mentions sequential mode triggers, which favor precise placement over speed. That suits careful shingle work on a pitched roof, where a stray nail costs more than a slower pace. It ranks third on our list.
VerdictThe CN45C is a straightforward pick for careful shingle work, held back by missing carbide and warranty details.
3PLUS HCN45SP offers trigger choice but a thin spec sheet
The HCN45SP ranks fourth on our list, but its spec sheet is thin. The data lists no weight, operating pressure, firing rate or warranty. That makes it hard to judge arm fatigue over a long day. What it does list is a 120-nail magazine, a 15° angle and nails from 0.75 to 1.75 in.
Its trigger setup is the main feature. An interchangeable trigger lets you choose single shot or sequential action, or bump fire. The listing warns about double fire from recoil in bump mode. Roofers should read that warning, since pressing hard can drive a second nail. Sequential use is the calmer choice near edges and on steep pitches.
Roof controls look good on paper. The data lists tool-free depth adjustment and a shingle guide. The listing adds side skid pads, which keep the tool from sliding off a roof when set on its side, and a 360° tool-free air exhaust. At 11.8 in, the body is the second longest among the eight models that list length.
VerdictThe HCN45SP offers useful roofing features, but missing weight and pressure data make it a harder call.
AEROPRO CN45RC is light, but lists no shingle guide
The CN45RC weighs 5.5 lb. Only one model on the page, at 4.93 lb, lists a lower weight. That helps on long days and overhead reaches. It is a 15° coil nailer for 0.75 to 1.75 in nails, with a 120-nail magazine and tool-free depth adjustment for different shingle sizes.
Power is where it differs. The working range is 70 to 110 PSI, and that 110 PSI top end is the lowest among the eight models that list pressure. Firing rate is 3 nails/sec, matching the lowest listed among four models. Compare that with 10 nails/sec on the Metabo HPT. Roofers on large decks may notice.
It ranks fifth on our list. The data shows no shingle guide, carbide nose, trigger mode or warranty. The listing mentions a cylinder valve drive and an improved nail feeder meant to reduce misfires and jams. At 11.03 in, the body is shorter than the Bostitch at 13.38 in.
VerdictThe CN45RC is a light, simple nailer, but it gives up speed and shingle spacing help.
Best among the reviewed tools
Check the nail length range first. Most models here drive 0.75 to 1.75 in nails, and a few start at 0.875 in. Also check the collation angle. Most list 15°, but the Metabo HPT uses 16°, so nails are not interchangeable.
You hold a roofing nailer for hours, so weight matters. Listed weights run from 4.93 lb to 5.95 lb. A fraction of a pound adds up by the end of a shift. Check tool length too, since a shorter body fits tight spots.
Tool-free depth adjustment lets you set nails flush as shingle thickness changes. A shingle guide helps keep courses evenly spaced. A carbide nose resists wear. Not every model lists these features, so check each spec row before you decide.
Sequential firing places each nail on purpose. Bump firing is faster on open decks but can double fire from recoil. Some models switch between modes, one has an interchangeable trigger, and one is bump only. Choose by how you work.
Models on this page drive coil roofing nails from 0.75 to 1.75 in, or 0.875 to 1.75 in on some. Check the angle too. Most list 15°, while the Metabo HPT NV45AB2 uses 16° nails.
Listed weights on this page run from 4.93 lb to 5.95 lb, with most near 5.5 to 5.8 lb. One model does not publish a weight. Lower weight helps during long days on the roof.
Most models here list an operating range of 70 to 120 PSI. The AEROPRO CN45RC lists 70 to 110 PSI, and the Carpenter Air Tools CCN45 lists 70 to 115 PSI. Check that your compressor can supply the range.
Sequential fire is more precise and safer near edges. Bump fire is faster across open decks but can double fire from recoil. The Metabo HPT NV45AB2 and HBT HBCN45P list switchable modes, and the 3PLUS HCN45SP has an interchangeable trigger.
