DeWalt 20V MAX Brushless Cordless Roofing Nailer
Score: 82/100Rankings

The Bostitch RN46-1 is a lightweight pneumatic coil roofing nailer designed for high-volume professional tasks, featuring a patented side-load canister for fast reloading. It delivers exceptional power-to-weight ratio and includes a dry-fire lockout to prevent damage. However, it requires perfect perpendicular alignment to avoid angled nail sets and may cause accidental discharges in tight spaces.

The DeWalt DCN45RN is a cordless 15-degree coil roofing nailer designed for portability and quick setup on small jobs. Its tool-free adjustments and brushless motor are key strengths, though the nail door clip mechanism has been criticized for being sluggish. It is best suited for roofing professionals needing portability for service repairs or touch-ups.
