DeWalt Roofing Nailers

The DCN45RN is the only cordless roofing nailer DeWalt currently makes. It runs on the same 20V MAX batteries as the rest of the DeWalt platform, fires a standard 15° wire-collated coil nail, and weighs 8.7 lbs with the battery — substantially heavier than any pneumatic in the class.

That weight is the trade-off for never needing a compressor. For service trucks doing repairs, valley work, ridge caps, and tarp jobs, the DCN45RN is the right call. For a 30-square tear-off, it's the wrong call.

DeWalt no longer markets the DW45RN as a current production model, but the gun is still in working trucks all over the country. At 5.36 lbs it's lighter than a Metabo HPT NV45AB2 and competitive with the Bostitch RN46. Drives 7/8" through 1-3/4" coil nails at 70–120 PSI.

If you have one and it still cycles cleanly, keep it. Standard rebuild parts are still on the shelf.

The honest answer: most production crews still pick the pneumatic. Most service and repair guys pick the cordless. If you're doing a mix and only buying one, the cordless is the more flexible tool — it can do the production roof slowly, but the pneumatic can't do the ridge cap repair without a generator and a hose.
