Why production crews still pay the premium for MAX roofing nailers
The all week tool
MAX is the brand you reach for when the job is going to take all week. The CN445R3 SuperRoofer has been the production roofer gold standard for over a decade. 5.1 pounds, magnesium housing, and a depth of drive system that holds setting after thousands of shots.
You will pay 30 to 40 percent more than a comparable Bostitch or Metabo HPT. Pros who run a nailer six or more hours a day make that back in the first season.
CN445R3 SuperRoofer cult following
The CN445R3 is the lightest pro grade pneumatic roofing nailer on the market at 5.1 pounds. Combined with the near vertical exhaust and rubberized grip, it dramatically reduces shoulder fatigue on long runs.
It drives 7/8 inch through 1-3/4 inch wire collated coil nails with a depth adjustment that holds zero. Magnesium body rated for 2 million shots before rebuild. Tightest depth of drive consistency in the category. Top tier balance keeps the gun put when you let it hang.
Choosing between CN445R3 and CN450S MAX roofing nailers
The CN450S is the heavy duty sibling. A hair heavier, more raw driving power, designed for thicker decks and tear-overs. If you do a lot of re-roof work over an existing layer, this is the pick. Most new construction roofers stick with the CN445R3.
Both guns accept any standard 15 degree wire collated coil roofing nail in the 7/8 inch to 1-3/4 inch range. We recommend 1-1/4 inch hot dipped galvanized for everyday shingle work and ring shank coils for high wind zones.
Frequently asked questions
- Why do production roofers pay extra for a MAX?
- Three reasons: weight (the CN445R3 is the lightest pro coil roofer at 5.1 lbs), durability (alloy housing rated for 2M+ shots), and the famously tight depth-of-drive consistency. On a full-day tear-off, the weight savings alone is the difference between a sore shoulder and a normal one.
- CN445R3 vs CN450S — which one?
- The CN445R3 SuperRoofer is the lightweight everyday driver (7/8" to 1-3/4"). The CN450S is heavier-duty for thicker decking and tear-overs, drives up to 1-3/4" coil nails with more raw power. Most pros pick the CN445R3; framers crossing into roofing pick the CN450S.
- Will any 15° wire-collated coil nail work in a MAX?
- Yes. MAX uses the standard 15° coil collation that fits Bostitch, Hitachi/Metabo HPT, DeWalt, and Senco coils. No proprietary fasteners.
- Is MAX worth the price over a Bostitch RN46?
- If you're nailing roofs every day, yes — the weight and longevity pay back fast. For weekend or occasional work, the Bostitch is the smarter buy.
