Our roof was originally concrete tile, and these are dark brown

high heat and almost vertical lie, the weight probably was too much
for our roof. Nailing 1/4" over the nailing line means you catch
only the top 1/4" of the top layer of the shingle.

Doesn't changing the mansard from tile to asphalt shingles 'cheapen' the
neighborhood?
