Around here, a good quality architectural grade asphalt shingle will last
about 20-25 years (my current roof is 16 and still looks brand new), which
is a fair trade off in the savings on structural members in the roof (2x6,
24" on center). The main upgrade here is a metal roof which costs about
double but will last considerably longer. The great equalizer is
hurricanes. We get a really bad one on average 20-25 years and no roofing
material is immune. Plenty of old houses downtown with slate shingles had
major damage. Owners had to go back to the original English quarry for
replacement (Hysterical Society requirement) to the tune of $75000 and up.
