A good coil roofing nailer drives long roofing nails to a steady depth, holds enough coil nails to limit reloads, and stays light on a long day. Check the nail length range, the magazine capacity and the weight first. Then look at depth adjustment, the shingle guide and carbide nose inserts. Nail collation angle matters too, because the coil must match the tool. We put 12 products on one spec sheet so you can compare these numbers side by side.

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. We note what each maker publishes and what it leaves out.
Bostitch RN46 leads our ranking on features
The Bostitch RN46 ranks first on our spec sheet. It covers the full feature set a roofer looks for. It has tool-free depth adjustment, carbide nose inserts and a shingle spacing guide. Depth adjustment helps nails sit flush in shingles. Carbide inserts resist wear on the nose. The guide keeps courses evenly spaced. Wear guards and skid pads protect the tool body.
It drives 0.75 to 1.75 in nails from a 120-nail magazine. That capacity means fewer stops to reload on a large roof. Nails load through a single-action side canister. The listing also describes a zero nail lockout that prevents dry firing and signals when the magazine is empty. It runs at 70 to 120 PSI and takes 15° coil nails.
The tradeoff is size. At 13.38 in it is the longest tool among all 12 products on the page, and it weighs 5.8 lb. That adds bulk on a roof. Buyers who work on tight roof sections may find that length awkward, so check the fit before you commit. The maker does not publish a firing rate or warranty length.
VerdictA well-equipped coil nailer for roofers who value features over compact size.
Metabo HPT NV45AB2 pairs speed with a short body
The Metabo HPT NV45AB2 ranks second. It lists the highest firing rate among the models that list one, at 10 nails/sec. On a roof, that rate keeps the tool ahead of your hands when you work along a long course of shingles. Its 9.84 in body is also the shortest among models that list length, which helps in tight spots.
Depth adjustment is tool-free, and the tool operates from 70 to 120 PSI. It takes 0.875 to 1.75 in nails from a 120-nail magazine. The magazine angle is 16°, the highest on the page, so you need 16° coil nails rather than the 15° kind most others use. Check your nails before you buy.
Weight is 5.7 lb, and the listing calls it well balanced. The warranty is 5 years, and the trigger switches between sequential and bump modes. Bump mode is fast, but it needs care on a pitched roof. That makes it a strong match for production work on open decking. The maker does not list carbide inserts or a shingle guide.
VerdictA fast, compact nailer for roofers who can buy matching 16° nails.
Dotool CN45C is a light, simple 15° option
The Dotool CN45C ranks third. At 5.6 lb, it is light enough for long days on a roof, and the listing describes it as well balanced to cut fatigue. That is close to the middle of the pack among ranked models. The housing is aluminum. It has a shingle spacing guide and tool-free depth adjustment, so nails can be set flush and courses kept even.
It accepts 0.75 to 1.75 in nails in a 15° wire coil. The magazine holds 120 nails, which limits reloads, and nails load from the side. Operating pressure runs from 70 to 120 PSI. The listing also mentions a tool-free jam release and a magnetic nail holder that aligns nails during loading.
The maker does not list carbide nose inserts, a firing rate, tool length or warranty. Without carbide, nose wear on abrasive work is an open question. The listing describes sequential mode triggers, which favor precise placement over speed. That suits careful shingle work. Buyers who rely on a long warranty or a rated firing speed will find nothing to compare here.
VerdictA light, no-frills coil nailer that covers the basics but publishes fewer details.
toolant TA01105 is a plain pneumatic 15° choice
The toolant TA01105 ranks fourth. It is a pneumatic 15° coil nailer with an aluminum alloy shell. It weighs 5.7 lb and measures 11.61 in long. The listing quotes a 3 nails/sec firing rate, which is enough for steady shingle work but well below the 10 nails/sec the Metabo HPT lists. That rate may matter little if you place each nail with care.
Nail range is 0.75 to 1.75 in, with a 120-nail magazine and a 70 to 120 PSI operating range. Those figures match most of the field. The warranty is 3 years, which gives some cover. The listing mentions an anti-slip grip, a dual-trigger safety and an air inlet that fits most compressors.
Several features are missing from the data. The maker does not list tool-free depth adjustment, and it does not list a shingle spacing guide or carbide nose. Depth control matters on shingles, where a nail driven too deep or too shallow causes problems. Check how depth is set before you buy. Higher-ranked models list tool-free adjustment.
VerdictA basic, covered nailer that lacks the depth and guide features higher-ranked models list.
HBT HBCN45P is the lightest on the page
The HBT HBCN45P ranks fifth, but it leads on weight. At 4.93 lb it is the lightest among models that list weight, and its housing is magnesium. Less weight means less strain when you work overhead or climb a pitched roof all day. For a roofer, that is the main reason to look at it.
It also has carbide nose inserts and a shingle spacing guide, plus tool-free depth control. The trigger switches between sequential and bump modes. Nail length runs from 0.875 to 1.75 in, and the listing says it drives 11 gauge full head coil nails. Skid-resistant pads and wear guards protect the tool.
The gaps are in the data. The maker does not publish magazine capacity, operating pressure, firing rate or warranty. Magazine size decides how often you reload, so you will want to confirm it before buying. The 4.93 lb figure also beats the 5.5 lb of the AEROPRO models. Tool length is 11.4 in, which is mid-range among models that list it.
VerdictThe best pick for a light tool, as long as you confirm the missing specs.
Best among the reviewed tools
Check that the tool takes the nail length your shingles and decking need. Many models here accept 0.75 to 1.75 in nails. Also confirm the collation angle. Most list 15°, but one lists 16°, and the coil must match the tool.
Every ranked model that lists capacity holds 120 nails. That limits trips to reload on a large roof. If a maker does not publish capacity, as with the HBT, confirm it first. A zero nail lockout, listed on the Bostitch, also warns you before the magazine runs dry.
Weight adds up over a full day on a roof. Listed weights run from 4.93 lb to 8.1 lb across the page. Most ranked models sit between 5.5 lb and 5.95 lb. Tool length matters in tight spots, with listed lengths from 9.84 in to 13.38 in.
Tool-free depth adjustment lets you set nails flush without a wrench. A shingle spacing guide keeps courses even. Carbide nose inserts resist wear on abrasive surfaces. Not every model lists all three, so check each spec row before you decide, especially for depth control.
Most models here take coil roofing nails from 0.75 to 1.75 in. Some start at 0.875 in, including the Metabo HPT, HBT and Carpenter Air Tools models. Pick a length that passes through the shingle and grips the decking, and match the coil angle.
Most ranked models list a 70 to 120 PSI operating range. 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 steady pressure in the range your nail and decking need.
Less weight helps on long roof jobs, but it is not the only spec. The HBT HBCN45P is the lightest listed at 4.93 lb, yet it leaves out magazine capacity and pressure. Balance weight against depth adjustment, nail range and the details the maker publishes.
Sequential mode fires only when you press the tip and then the trigger, which favors precise placement. Bump mode fires faster but needs care on a pitched roof. The Metabo HPT and HBT switch between modes, while the Carpenter Air Tools CCN45 is bump only.
