Thank you Dave! I never heard of Bollinger Edgerly Scale Trains. I see they have some nice HO kits in addition to the shingles in 3 scales. Yes, this station should have light gray slate shingles, and I would need 4 sheets; $48 plus whatever shipping and tax they charge. Well, this model is worth it.
I think the 3/16 or 1/4 strips lengthwise would be needed for this model also. Better to overbuild than underbuild and break one of the roofs when handling. That is a nice building you pictured above! Congratulations on your recent retirement. I was given early retirement in late 2018. In mid 2019, I got a part time job and needed off for a knee replacement right before the pandemic started. I never went back. We are doing fine.
