Here here, tin foil at best. Buying material at Home Crapo and Howes and
then commenting on components of a quality roof install and the omition
of drip edge requires a good look in the mirror. A little over the top,
but using home center drip edge is a modest step at best above not using
it at all. It is the thinnest material, thinnest finish, and shortest
profile that could be considered worth installing in the first place.

But they haven't been around yet for 50 years so I personally take these
guarantees with a grain of salt. I'll believe it when I see it. My
30 year shingles are only 6 years old and I'll be very surprised if they
last 24 more years.
Not sure if I'm willing to wait another quarter century for your full
report, but good luck with it anyway!
The guarantee doesn't mean that there _won't_ be problems. It means
if and when there are problems you probably won't see jack. Subtle
True. However, if the drip edge is installed correctly it should be
over top of the roofing felt along the gables and thus should be removed
for a proper refelting anyway. I know, I know, many folks just slap a
new layer of shingles on over the existing, but I never liked that practice.
Also true, but it is common and can save substantial amounts of money when
you figure in the demo and haul cost of removing an existing roof.
BTW, I always design my roof systems to allow for two layers of asphalt

Ripping off instead of reroofing also loses that valuable R-0.1
insulation from the old layer of shingles.
Asphalt? You're showing your age, Bob. Or, maybe the shingles
My favorite was the house with 2x4 rafters that had cedar shingles and
two layers of asphalt shingles - well, maybe the top one was
You can generally tell the reroofed-too-many-times-with-inadequate-
framing houses by the sway-backed ridge. That's usually the first
place it shows up.
Exactly. The warranties are pro-rated such that you aren't going to
get much if a 30 year shingle lasts 20 years. Also, the chances of the
shingle manufacturer being around in 50 years are probably the same as
my being around, pretty slim.
