Interesting to hear that. I would estimate the color of my shingles to be
similar to a photographer's 18 percent gray card. As I'm having the roof
redone, I could switch to a white shingle.
But, I thought that builders increase the pitch of the roof at high
latitudes, causing them to shed a lot of the load, and reducing the load per
square foot. Ie., the roof typically found on a Swiss chalet. My house, a
bit north of Philadelphia, has a roof pitch I estimate at 15 degrees. The
snow comes off within a week due to melting.
What is the pitch of your roof?
