Why siding nailers are not just longer roofing nailers
Different gun, different geometry
Siding nailers look like roofing nailers but they are tuned for completely different work. The drive force is lower so you do not crack fiber cement or split cedar. The nose is narrower so it fits between courses. And the depth adjustment has more travel to handle the variation between vinyl, fiber cement, and engineered wood.
Trying to use a roofing nailer on siding will overdrive the fastener nine times out of ten. Use the right tool the first time.
Coil vs strip for siding work
Coil siding nailers (Bostitch N66C, Hitachi NV65AH2) hold 200 to 300 nails per load and reload less often. Best for production lap siding work where you fire hundreds of nails per wall.
Strip siding nailers hold 30 to 40 nails per stick and are lighter, more nimble, and easier to feed into corners. Better for shake, shingle, and trim work where precision matters more than fire rate.
Sizing and fastener pick for siding nailers
Match the nail to the substrate. Stainless ring shank for cedar shake and shingle. Hot dipped galvanized smooth shank for fiber cement. Standard galvanized for engineered wood siding (LP SmartSide and similar).
For length, follow the manufacturer spec sheet. Fiber cement plank typically wants 6d (2 inch) blunt point. Cedar shake wants 5d (1-3/4 inch) box nail. Vinyl wants 1-1/4 to 1-1/2 inch with a roofing style head. See our siding nailer vs roofing nailer guide for the decision matrix.
Frequently asked questions
- Can I use a roofing nailer for siding?
- No, not safely. Roofing nailers drive harder than siding nailers and will crack fiber cement, split cedar, and overdrive vinyl. Use a dedicated siding nailer with adjustable depth-of-drive.
- Coil siding nailer or strip — which?
- Coil for production lap siding (200+ nails per load). Strip for shake, shingle, trim, and detail work where precision and maneuverability matter more than reload time.
- What angle is a typical siding nailer?
- Most coil siding nailers are 15 degree wire-collated. Strip siding nailers are typically 28 to 34 degrees, similar to a finish nailer angle. Always verify the gun spec before buying nails.
- Do siding nailers shoot the same nails as roofing nailers?
- No. Siding nails are longer (typically 1-3/4" to 2-1/2") and have smaller heads. Roofing nails are shorter (7/8" to 1-3/4") with large round heads. They are not interchangeable.
