Yeah. "Warranty void if product exposed to sunlight."
Typical corporate CYA.
"Limitations and exclusions apply."
Here is a random rule of thumb from an entirely
different source:
"As shingle degradation is large a function of oxidation,
the rates of this decomposition can be expected to
follow the laws of chemical reactions. Accordingly, if
the average shingle temperature was elevated
by 2°F, the shingle life expectancy might be reduced by 11%."

Based on the 50 - year warranty for the product we bought
and the essentially unvented character of the attic
No gable vents or soffit vents?
Two gable vents and ~12 rafter - end vents
are all 'gozintas'.
That is on the 'input' side, low on the roof.
You also need a 'comezoutta'. Before the re-roof,
we had full length ridge vents. After the re-roof,
we had a few of these dinky little useless
'eyebrow' vents. No Comezoutta.
Illustration: I was replacing rafter-end-vent
grills on the end of the house opposite the
incoming prevailing wind. Each time I would
pop a grill off, I'd get a face full of hot air
from the attic. Now, that air should have been
exiting out the top of the house instead.
It had nowhere to go, as a practical matter.
space before I installed my three solar power vents,
I suppose that I am all done worrying about roofing!
Cha CHING!
It's one of those 'pay me now or later' things.
I think we covered my reasoning behind the
solar power. You might reasonably say I should
have used some of those wheely turbine deals.
The aesthetics chief would have hit the roof!

Careful, you're making SENSE now...
I suppose it had to happen eventually.....
Well, the potential was there, anyway.
Your faith is boundless.

A) Alternative energy is a real interest of mine.
I like participating to some small degree.
Then why didn't you build your own?snicker
I wanted it to work properly without any snags, first thing
Oh, ye of little faith...
Well *no* faith actually.
out of the box. This old guy is tired enough of clomping
about on the roof.
I hear that.
I think a wind charger would be a *lot* more fun anyway!

SWMBO is the aesthetic in the family. She chose a blend
of colors that tend toward the (cough) um. dark.
You couldn't sway her with comfort/cost savings, eh?
First I heard of the decision, the shingles were on the roof.
I doubt I could have swayed her with a '3 degree F' argument.
Can you say PW?gd&r
She is SWMBO for a reason.

Yabbut, think of the temp rise in the actual shingle to get your 3
degrees through the wood.
It's a bunch, I agree.
In looking at the paperwork just now, I found these are
'lifetime' guarantee shingles with 10 years parts and
labor. SWMBO told me the warranty was 50 years.
Not that it matters to either of us!
(Color / heatrise relationship)
Oh, you didn't know?
See above. I suspected, but the aesthetics director made
the call. They look very nice.

Please post to YouTube.
Oh, so you're likin' the infamy, are ya? No, I won't post it.
I just wanted to hear what 'nonplussed' sounded like
over the phone.
