Lower offer price or ask to make repairs?

Hey BP, I’m in the inspection period of my first deal. A duplex with intent to owner occupy. I’ve already gotten the whole home inspection which revealed some things I was expecting (roof with only a few good years left, old furnace and water heater) and a few things I definitely was NOT expecting (outdated electric on 60 AMP service). Not sure how to handle moving forward with this deal. I had most of the things that needed to be fixed in my numbers, but even the roof is older than I had planned for. I really want to ask for the roof repair and the electrical to be updated and brought up to code. What’s a good way to ask without putting the seller on too much of a defensive? Or should I just lower my offer to compensate? Curious as to how some other investors would handle this situation.
