Roger,
I realize that the existing shingles have faded over time but what I
was wondering is...are the new shingles going to be the exact same
shingle as the original shingles that were manufactured 15 years ago?
Even though they call them the same - Do you think the Weathered Wood
shingle bought today is the same make-up, color etc. as the original
shingles of 15 years ago?

I'd guess they probably won't match because the gritty layer on top,
which is supposed to wear away over time, would have worn away after 15
years. Also the colors could have faded slightly.
