Does anyone have any tips on how to best replace this roofing without covering all the trim with rubber? Also, how should treat these sills if I expose them?

It would depend in large part on the details of construction and conditions that are now hidden by the roofing.

If you open this up post more photos.

OK, I ripped this thing open. It needed to be done anyway because there was moisture under the rubber. It looks like the sill is covered with tin and the tin is wrapped around the trim. I don't know if this is original or not (house dates to 1878). I'm not sure how the moisture got in under the rubber. I took a picture of the roof to show how everything looks. It's not in very good condition as you can see but it seems sound. The previous owner put down this rubber and patched some of the tin seams but the cornice above wasn't sloped properly which created a 15 foot waterfall onto this roof.

This is what it looks like under the tin. I'm thinking this must be the original detail. Any feedback on that?

Yes, that does start to look original or early.

It looks like the roofing sheet metal originally came across the roof, then up vertically over the edge of the sill, then fits into a groove cut along the edge of the sill? If so, that looks like a pretty good detail.

What roofing material will you use on this roof?

I was leaning toward lining the inside of the roof with rubber and some kind of metal to replace the tin cap at that low wall until I can afford to replace the tin with something better. Any suggestions?
