Hello All,
I recently bought a farm with an old barn on it. I would love to restore the barn and keep the original slate roof. Does anyone know if it’s cost-effective to repair a slate roof? Any good resources on how to replace broken pieces of slate? I can only assume you would have to remove and completely reinstall.

Cost-effective? Depends on how much you need to repair. Google "replacing slate" there are tons of videos and how-to's on how to replace individual pieces. I live in Vermont, land of slate quarries, so there is a lot of relatively inexpensive slate available.
Replacing broken slate tiles is pretty easily done. You don’t need to remove the whole thing to repair, only the broken or cracked shingles. There are a couple things you’ll need. You need a slate ripper to slide under the broken slates to remove the nails and shingle itself. You can find videos online on how to do that. You’ll reinstall the new slate shingle using a copper slate hook. Theres a video in my second link below for doing that. Slate doesn’t really need underlayment, so I wouldn’t even worry about that part if dealing with an older building. I’ve included links to the tool and hooks below.
As for buying replacement slate, you can either source new slate shingles at your local building yard, but I prefer local architectural salvage yards. They always have different size slate shingles for cheap.

Thanks Josh. I learned something new today!
Oh wow, that actually looks really easy. I would have never imagined that. Fortunately, I have old slate from the house to use on the barn that will get replaced with modern shingles.
Thanks!
Years ago I owned a house with a century old slate roof. It cost me about $150/year in repairs, which, compared to the cost of a new roof, sure felt cheap.
Yes, it is really cost effective. A year ago, I changed the repaired the slate roof of my outhouse. We don't need to change the whole slate, we can replace the broken slates. So it's not a not deal but really effective.
My barn/shop, built in 1840, has a slate roof. The last time we replaced 5-6 was 21 years ago.
