Replacing asphalt shingles during winter?

I live in Missouri and its starting to get cold. I have to replace the sheathing(I think) and shingles on one side of my roof(for now) because I got a leak. I will replace the entire roof once summer gets here. This side of the roof doesn’t get a lot of sunlight.

I have never done roofs before but I have researched very carefully.

My question is, can roofing be done in cold weather with asphalt shingles?

no problem, if you hand nail.

I don’t have a problem hand nailing. But what do they usually use?

I only hand nail. I had a heated shop and when it got real cold, we’d only bring out what we could nail down in a couple hours
