How to Nail New Siding Under Existing Siding

Hi Everyone:

I have been a viewer on this site and this is my first posting. Great site by the way.

I have an older home (60 years old) that has cedar siding. The siding is about 15-1/2" to 16" long and the widths vary (3" to 12"). Each siding is exposed about 7". The siding is also tapered on one side and it is about 3/8" to 1/2" thick at the butt. I uploaded 2 pictures so you have a much better idea of what the siding looks like. One picture is the back side (non-exposed side) and the other one is of the garage, but the house exterior is the same.

The wall has no plywood or OSB sheathing. The framing is 2x4 with 1x4 continuous horizontal battens @ 6-3/4" O.C. The siding is nailed to the 1x battens.

I am need of replacing a few of the cedar sidings, but not the entire wall. My question is how do you nail the new sidings correctly under the existing siding above (covering) it? I want to be clear that I will be sliding the new piece under the existing piece that is in good condition, and will be nailing the new under the existing so that it must be secured to the 1x battens. By my estimate the nail will head will be about 1" (or so) above the overlap measured from butt end of the existing siding.

I refered to various websites, youtube videos, forums, Cedar Shake & Shingle Bureau, etc. and I cannot find a single source detailing how to nail replacing shingles so that the nail is below the existing siding sitting over the replacement siding. A few suggested nailing right through the existing and new, but that is not correct since it will not allow the exisiting to expand and contract.

Sorry for the long post but I prefer being clear to my situation then to take the reader off tangent.

Thank you

Hi Jay:

Thanks for the suggestiong but I am not totally clear. Are you refering to nailing right through the existing siding lying over the new below it then using a nail punch to push the nail clear pass the existing? Or are you suggesting nailing both the existing and new together? If latter then that is not suggested since the existing is now secured at the middle and butt end. When the existing wants to expand it is locked in and the siding will crack.

If you replacing boards in the middle of a wall there is no way to get around having to face nail it.
I would have used ring shank stainless steel siding nails instead of finish nails.

I came across this website for suggesting nailing under the existing course (see step 5). But it isn't totally clear to me what occurs to the new siding during step 6. Depending on the nail it will either bend upwards during step 6 or the nail will simply elongate the hole in the new siding when it is tap upwards by 1/2".

The only problem with that method (which I’ve done many times) is when you knock that shingle up that ¼“ is where it’s going to want to split. Looks great today but who knows later.

Op’s wall is painted, you’ll never notice a small face nail just below the coarse above.

Loneframer and Tom thank you for your responses.

As kwikfishron indicated I too believe that the elongation produced by the 1/2" or 1/4" shift by pounding the siding level will promote future cracks.

I do have a question with this procedure however. If you are able to pound the nail in at an angle with the siding at 1/4" lower than the adjoining siding why couldn't you close the distance further thereby eliminating the necessity to level by pounding the siding? Or is it the goal to get the bottom as close to level as possible prior to inserting the nail and pounding the siding afterwards is to ensure the course is level since it maybe impossible to level it in the first place?
