marginal vapor barrier on the warm side of the house insulation to be
exact.

Coincidently I priced it at Menards in Columbus, IN today and they told me
$36 for a 3' x 100' roll, granular.

Yep, and my roofer refuses to use the shit from menards because by the
time you fix all the tears etc, you would have been better off
spending a few more bucks.

The thing about buying stuff at Menards/Lowes/Home Depot, etc. is that the
choosing of products is the sole responsibility of the purchaser.
I sort of prefer that myself.
Just yesterday I purchased about $400 worth of PT lumber and anchor bolts
and various other things for a project I'm building and I *hand selcted*
every single component to assure that I received the best they had.
If your roofer spent time fixing tears and stuff you should have planted
your workboot squarely in his ass for wasting your time and resources.
A few minutes spent up front scrutinizing the purchases saves alot of
problems on down the line.
Quality builders know this, why don't you?

If you think that the roof is important, then you should also
consider your plumbing. Although, like placing IWS
everywhere, it is not common practice, placing all of your
plumbing pipes in PVC can keep that possible leak from
becoming a disaster. I have seen many more homes destroyed or
damaged by plumbing leaks than roof leaks. And I should know
as I am in the insurance repair business (15 years or so).

It is simple (like using IWS everywhere). Simply install 2"
PVC pipe everywhere that you need water, then run your copper
or PEX through the PVC. Should there be a leak, the PVC
contains it.

And hey, what about fire? It would probably be a good idea to
encase all of your combustable materials in concrete. That
way, there is nothing to catch fire except your personal
property and that could be treated with a fire retardant.

Don't forget about these other things and just add ICW.
Remember, a little extra goes a long way to protect your
quality home. Whats a few extra tens of thousands of dollars
when your peace of mind is at stake?
