Here's a panorama of Minneapolis from 1907 that shows lots and lots of roof and roof details: https://www.shorpy.com/node/27914?size=_original#caption

I wonder if Warner's Hardware has any connection to present day Warner Tools (painting related tools) of Plymouth, MN. Perhaps not as Warner Tools was founded in the 1930s
Appears Warner Hardware sold Sherwin Williams paint as seenin the "cover the earth" signage.
I really like these old pics

Only a few of those roofs are as messy as I remember from living in 1970s Boston. Very much pre-air conditioning.
The great Shorpy Photos but detest children as coal breakers.
