Yes that is common. Roofing nails come in a number of lengths to accommodate for the different thickness' of the decking material you are applying the roof to. Since the nails sell by weight they usual only barely extend into the attic. (ie fewer long nail per pound). You may have had brads before instead of nails. Nails are more costly but preferable.

Roofing nails come in different sizes(length) and usually purchased by the box in bulk by roofing contractors. Depending on the job>>how many layers of shingles, etc.-- a nail will be chosen to "fit" the job. A roofing contractor may just use the same size for all his jobs--or he may use what he has on the truck left over from other jobs. The nails must penetrate all the way through into the decking to hold the shingles against high wind,etc. Just watch your head when in the attic.

A shingle roof is applied in layers. The first is a layer of roofing felt (tar paper), which is secured by roofing nails which have large heads to hold the felt and which are driven through the felt into the underlying (usually ply-) wood sheathing which forms the surface of the roof. Because the nails are longer than the thickness of the felt plus the sheathing, their lengths exceed the plane of the underneath side of the sheathing and "stick out into the attic."

When I put a new composition shingle roof on my home the city required nails that ,in my opinion, were ridiculously long. The city inspector explained that the nails extending into the attic space had something to do with moisture condensing on the nails and then evaporating. Wish I could remember more. Hope this helps.

Yes. Perhaps with the old roof they used a staple of some sort. Did you have the plywood replaced also?? If yes, maybe the plywood wasn't at thick as the original plywood. Roofing nails are maybe one inch long and the plywood might be 3/4 inch thick.???

in the way-back, roofs were put on with roll roofing, which used short nails and "blackstrap" (roofing tar). You probably switched to shingle, and that DOES have nails that stick out.

I believe that is okay.
The nail heads are under the next course of shingles and so the nails going all the way through should not make it more likely to leak.

Yes, be glad they do. That means they used longer nails than the original roof.

yes, when you get shingles put on it is normal if the old shingles were taken off first. The more layers of shingles the less nail you will see. Not everybody takes off old shingles.

Yes.
Your old roof may have been put on with tar only.
