best roofing ice and water shield?

[Smarty]

Roofers I speak to seem to strongly prefer Grace I/W Shield over
Certainteed and Owens Corning btands despite a very big price
difference.

Is the double or triple cost worth it?

Thanks very much !!

The technology of all these underlayments is based on a butyl rubber
adhesive system that has been around for many years. There are similar
sealant products used around windows and doors. If the Grace material
is physically better I would be quite surprised. It does have an
advantage in a faster means of removing the paper backing, which to a
roofer (time=money) is an advantage. That, coupled with an
artificially inflated list price means more profit. For a DIY project
any of the major brands should be just fine. You might check the
different products out at your local lumberyard or box store to see if
there are discernable differences that would make one or another a
better choice. The rolls of the quality membrane will be quite heavy,
making comparisons easy. HTH

I have no personal knowledge as to which product is best. However, if
you are in the trades, 2x or 3x on material price is NOTHING compared to
the time and goodwill cost of having callbacks and rework. One bad job
can cost you 5 other jobs, once they tell their friends. And if the more
expensive material goes in easier and quicker, all the better.

Remember, labor is usually half to two thirds of the cost of any project.

Thanks very much Joe. I certainly would also tend to the heavier material,
all things otherwise being equal. Since I have 2 old roofs being removed,
and literally 20 to 30 thousand nails being removed in the process, I am
also thinking that the heavier materials will also provide a little better
puncture resistance if one or more nail heads are still sticking up from
prior jobs. I am not sure if this makes any sense or not, and perhaps the
felt paper / Titanium UDL underlayment takes care of this issue.

Many thanks again,

Yup, although the roofing people I have spoken to seem to be looking for
cost savings if they can find them, and this Grace ice and water protection
is expensive material, perhaps adding another 600 to 700 dollars to the cost
of the materials versus the cheaper stuff from Carlisle, Owens Corning, etc.
The Grace would be about $1200 whereas the Owens Corning is closer to 500
bucks.

My roofer sub likes the DuPont product similar to Permafelt from
Menards. I used the latter last summer and it is far better than felt
for that critical first layer. For DIY projects, it will give you many
days of leeway in completing the job and keep the weather out when
unexpected rain arrives. Probably better than felt for water
resistance and safer to walk on when the pitch gets over 4-12.

All depends how the job is bid out. Most residential rip'n'replace
around here is done as a job price, not time and material. As long as
customer trusts the roofer to not cut corners to get done faster, the
tradeoff between material cost/labor/reliability is a decision on the
roofer's part. Finding the sweet spot between cost and durability, etc.
On a multi-thousand dollar repair job, if $700 additional gets me an
extra 5 years of not worrying about leaks, it starts to look pretty
cheap. If it gives the roofer a warm fuzzy about less callbacks, he may
be willing to eat part of the cost difference. New construction is is
different- the GC or architect specs out the materials, and all the sub
has to play with are his labor costs, and how much markup to charge on
the material, if he is the one providing it.

I'm in the Midwest. Cost comparison, Grace & Certainteed are comparable.

I always preferred Certainteed (Winterguard) over Grace. Certainteed has
more workability, than Grace. On a 5/12 or lower slope, we would start the
roll at one end, and roll to the other end of the roof (with Certainteed),
instead of using 10 ft. pieces. We would chaulk a line to keep the shield
where we want it. Stripping back a corner of the split backing, and letting
it tack down. On Grace, it's adhesion is too quick, making the roll less
forgiving, meaning you must cut the roll to avoid wrinkles. I have no idea
if this makes any sense to you, but basically, Certainteed has a more
workability time, plus you don't have to cut the roll in smaller pieces to
install.

Certainteed guarantees their product, as long as the shingle is guaranteed
for. I haven't used Grace for probably 10 years, at that time, their
guarantee was only for 10 years. I would think they might have extended it,
to be competitive.

Its just as important to address others issues that can cause leaks
toi begin with, espically ice dams.

great attic venting clean gutters downspouts and drains, soffit vents
covered with insulation?

Absolutely, and many thanks to all for excellent suggestions.

Just make sure you tell the customer that you are using Grace and that it is more expensive. I had no knowledge of that. I received 3 estimates from contractors. Two were 20K for my rook and a third was 30K (for ice and water on the entire roof of my ranch). I immediately thought the third contract was trying to rip me off. It wasn't until I hired someone else and I spoke to the third contractor that he told me he was using Grace (He still didn't tell me Grace was twice as expensive as Owens Corning). I didn't find out about the price difference until I did my own research. So, from this home owner to you contractors, make sure you explain about the price difference between Grace and others!!!

So you're trying to tell us that the price difference between a $30K quote
for a roof job and the $20K quote is due to using a different water barrier?
I say your first impression was correct. And unless it's some very unusual
climate or a roof with low pitch, water barrier isn't needed on the entire roof
anyway. A few decades ago those products didn't even exist and roofs were
done without them.
