15 Degree Roofing Nailer CN45N - Low Recoil, 120-Pc Capacity

Our review of the CN45N roofing nailer finds it best suited for roofers and serious DIYers who need a dependable tool for repetitive shingle work; the single biggest reason to buy is its combination of low recoil and a large 120-pc coil magazine that lets users fasten a full bundle of shingles without constant reloading. The nailer balances power and comfort with a moving cylinder engine for reduced kickback and a soft grip for longer sessions, so projects that demand consistent driving and fewer interruptions are where it shines.

Key Features

• Low recoil moving cylinder: The engine design reduces kickback for steadier handling and less fatigue during long roofing runs.
• 15 degree compatibility: Accepts 15 degree wire collated roofing nails from 3/4 in to 1-3/4 in for common shingle and sheathing needs.
• 120-pc coil magazine: High loading capacity allows a full bundle of shingles to be fastened without repeated reloads, saving time on the roof.
• Durable contact safety: Steel safety with dual carbide inserts reduces wear on the contact tip for longer life under heavy use.
• Magnetic nail holder and tool-less adjustment: Magnetic alignment helps jam-free loading and depth of drive is adjusted without tools for precise, flush driving.

Who It's For

The CN45N is aimed at professional roofers and experienced DIY contractors who work with asphalt or cedar shingles, roof and wall sheathing, or who need to assemble wood crates and underlayment quickly. Its big coil capacity and solid build make it practical for multi-hour jobs where fewer reloads and reliable drive depth matter.

People who prioritize the absolute lightest tool for long carry routes or those who only do occasional small jobs might look elsewhere; customers note some disagreement over weight, so if minimum mass is a top concern, compare handheld weight before you buy.

Pros & Cons

Pros

• Strong driving power and consistent performance in tough materials thanks to the low-recoil moving cylinder.
• Large 120-pc magazine reduces downtime for reloading and speeds through bundles of shingles.
• Thoughtful durability features such as steel contact safety with dual carbide inserts improve service life under heavy use.
• Easy loading and magnetic alignment cut down on jams and make reloads quicker and simpler.

Cons

• Some users disagree on the tool's weight, so it may feel heavier than alternatives for extended overhead work.
• Compatibility limited to 15 degree wire collated nails, so other nail angles require a different tool.
