Very nice. N scale - whoosh! You're braver than me. For roof flashing, you can get styrene sheets from Evergreen that are 0.005" thick - that's about 3/4" in N scale. For some reason, they don't offer any strips that thin (nor does Plastruct) - seems a waste to cut a small piece out of a huge sheet, but there you are...
Thank you so much. Ha ha, just a little brave. You're right about the styrene, and I should have thought of it. I have the 6x12 sheets in .001 thru .004 in my stash, along with plenty of scraps that would have worked. It's just getting used to working in N scale. LOL
