The Makita AN454 1-3/4" Coil Roofing Nailer is a pneumatic roofing nailer built for asphalt shingle installation and similar roofing fastening work. This is a roofing nailer designed for fast, repeatable shingle fastening with coil nails. Model Number AN454. If you want a dedicated air nailer that stays light in hand, loads quickly, and gives you better control over nail depth, this is the kind of tool that earns its keep fast.

This nailer drives standard 0.120-inch shank diameter coil roofing nails from 3/4 inch to 1-3/4 inch long, which puts it right in the range most roofing crews need for common shingle applications. Makita also gives it a 120-nail magazine capacity, so you can keep moving instead of stopping constantly to reload. The built-in magnet that ensures the last nail is driven is one of those small features that matters more on the roof than it does on paper, because it helps reduce wasted motion and unfinished cycles at the end of a coil.

Where the AN454 separates itself is jobsite practicality. The tool-free depth adjustment dial lets you tune the fastener setting for flush nailing shingles without dragging out extra tools. There is also a tool-free shingle guide for easier adjustment and more consistent shingle placement. That means faster setup when conditions change and less fiddling when you are trying to keep your courses clean and uniform.

Makita built this model around an aluminum housing to balance durability and lower carry weight. At only 5.2 lbs, it is easier to handle for overhead work and repetitive placement than bulkier roofing nailers. The ergonomic rubberized grip helps with control, and the reversible 3 inch belt hook makes it easier to keep the nailer close when you need both hands free climbing or repositioning.

For long-term wear, Makita added large carbide inserts on the nose piece and oversized steel wear plates to reduce abrasion on the tool. The smooth nose design also helps with tar buildup removal, which is a real-world roofing detail, not brochure filler. A removable nosepiece assembly makes cleaning and maintenance easier, especially for a tool that is going to spend its life around granules, adhesive residue, and outdoor debris.

From an air system standpoint, the AN454 runs at 70 to 120 PSI and uses a 1/4 inch NPT inlet. Makita lists minimum recommended air delivery at 2.2 SCFM at 90 PSI, while supplementary retailer data lists 3.7 SCFM at 90 PSI, so compressor sizing should be confirmed against your setup and use pattern. Either way, this is a pneumatic nail gun intended for roofing crews and contractors already working off an air hose and compressor, not someone looking for a battery platform tool.

Who should buy it? Roofers, remodelers, siding and exterior crews, and general contractors who want a purpose-built roofing nail gun rather than making a framing or siding nailer do a job it was not meant for. If your work is mostly shingles and you care about lower weight, easy depth control, and durable wear points, the Makita AN454 1-3/4" Coil Roofing Nailer makes a strong case.
