I have 3 quotes for a tear-off and reshingle of my roof.
The roof has one layer of existing shingles. The shingles
are selling for $100 a square at Lowes. Roof is 40 square.
Estimates work out to $270 to $335 a square. Any sheathing
replacement is $50 a sheet. Job will be #15 lb felt, ice dam
material on lower 3 ft. Double felt on garage roof, which is
low pitch. New ridge vent to be installed along entire peak.

It's in NJ, which is bad enough as far as prices and Im sure
Sandy is still a factor in prices. I need to get it done, so
waiting isn't an option.

Any recent experiences with prices to share?

Long time since I did mine but 2nd roof did not require complete tear
off and while shingles were in bad shape they covered with a longer
warranty textured type shingle which hid any imperfections. I also
skipped ridge vent. Probably been 20 years and my roof still looks good.

Have any of them quoted anything other than 15 lb felt?

I went with the GAF Lifetime system which included the WeatherWatch
leak barrier underlayment over the entire roof deck. See he

BTW...It wouldn't make sense for me to share my price since I had
gutters, soffits and some vinyl trim work done. All of the estimates
that I got (that were worth considering) were to do the entire job. No
one quoted me a "per square" price just for the roof.

I think I mentioned a while back about the one contractor that
presented a quote that was 1/3 higher than the quotes from other
contractors. When I asked why he charged so much, he pulled out
pictures of all of his trucks and the buggy lift they just bought. He
said "My overhead is higher than a lot of other companies."

My response: "You want me to pay 25% more for a sheet of plywood
because you have a fancy truck? Once you nail it down, is that plywood
going to perform 25% better than the other guy's plywood? After the
job is over, is my roof going to look better or last longer because
you used buggy lift instead of a ladder?" He couldn't do much more
than mumble something unintelligible.

I didn't even take the estimate out of his hand. He then drove off in
his fancy truck.

http://www.gaf.com/Roofing/Residential/Products

Regarding using a ice dam product on the entire roof,
I found guys arguing both sides of that one. The ones
who seemed to have the science behind them, eg a
building sciences professor, were generally against it.

The proponents say:

it gives better water protection for the whole roof

Those against say:

it seals the roof, which is great to a point. But sooner
or later some water gets in someday and with the barrier,
the wood can't breathe from the topside like it can with felt.
Moisture can't get out and the wood can rot. Those in
favor of using it say the sheathing can still breathe and
dry out from the attic side. Those against say, yes, that's
true, but it's better if it can breathe from both sides. Those
in favor also say that with felt and shingles, the roof can't
breathe from the top anyhow. The other side says yes it
can......

Bottom line for me is the existing roof lasted 28 years
with just felt, no ice dam stuff at all, no leaks, no problems.
So, I'm OK with just felt which is less expensive and less
labor intensive. Two of the 3 roofers want to use the
ice dam stuff on the entire garage, which is low pitch.
Other guy says two layers of felt is better.... Again, since
that's all that's there now, seems OK to me.....

I think I had his brother here a couple years ago when I
went out for bids on a new furnace/AC. This one company,
which is pretty large, has a whole fleet of nice new trucks,
flashy paint jobs. I see them all the time driving around.
The estimator was the only guy who
took of his shoes and put those cute little booty things on
before he set foot in the house. His quote was $14K.
The next highest was under $10K. And he had
a deal where if I signed right away, I got like $1000 off,
but it I didn't, that special was gone forever. When I told
him he was out, he tried to justify his price. That lineset,
for the AC, it costs $1000! I had already priced it out
online and found I could buy it myself for like $220,
qty 1.

Back to the ice barrier stuff for the whole roof, I just
thought of one more thing that never occured to me before.
Once you have that stuff stuck on, it's like on for good, no?
So, if someone goes to replace the roof again, I would
think it would make checking the condition of the sheathing
a lot harder, if not impossible, at least from the outside.
All the wood would be covered and you would not be able
to see it's condtion like you would if it were bare, no?

I don't have any recent experiences to share, but that's only a 25%
spread between the low/high estimates. That seems pretty close to
me. My interpretation is that those represent reasonable prices in
your area. I like the 15# felt because of it's durability. I never
liked the looks of the light weight stuff (5# ??). I even used the
15# stuff under exterior siding.

Given that price spread, I would go with whoever looks like they are
most competent.

My mistake. It wasn't the WeatherWatch that replaced the felt, it was
DeckArmor:

http://www.gaf.com/Roofing/Residenti...ion/Deck_Armor

When I was talking to the contractor and asked him about leaving any
section of the roof uncovered during the job, he said that they don't leave
for the day unless the DeckArmor is installed on any exposed decking. Per
the installation instructions, if installed properly, the DeckArmor can be
left uncovered for up to 6 months.

http://www.gaf.com/Residential_Roofi...structions.pdf

The WeatherWatch was used only on the first 3 ft on the main sections of
roof. We have a fairly flat section of roof on a small addition. The
WeatherWatch was used on that entire section. Every contractor that gave me
an estimate recommended that for the flattish section.

Sorry for the confusion.

See my earlier response. I named the wrong product...it was DeckArmor that
replaced the felt, not the WeatherWatch ice barrier.

The deck armor is apparently breathable, so it takes care of

to rain for months. But since I'm going to have a dozen monkeys
doing the job in a day or two, that isn't an issue. Now if I was

Just to be clear, the Deck-Armor wasn't used because of it's ability to be
exposed. It was used because it is required by GAF in order to get the
lifetime warranty on the shingles. My mention of its "exposibility" was
simply to point out that is must be much better (not sure that's the right
word) than standard felt.

The roof itself was done in 3 days, torn off and reshingled in two. There
was only one night when the roof, with the Deck-Armor installed, was left
unshingled. I assume even felt would have handled that. Do they leave felt
exposed over night? I don't know if I've ever seen that...could just be my
lousy memory. Tarps I've seen.

I took a look at GAF's warranty and installation instructions for
their
Timberline shingles. Nothing there says you have to use their
underlayment.
They just give their products in the installation instructions as
examples
of underlayment.

I agree, it's much better if the roof is going to be exposed for
an unusual length of time with just the underlayment, like if it's
a DIY job. But I don't think it has much advantage when the
job is done in a day or two. I guess it might help if you have
extensive shingle blow off in a storm and the better underlayment
managed to survive. I just had that happen
with Sandy. I lost one large section of shingles right at
the peak, about 4 ft wide and 20 ft across. The felt went too.
Whether the more durable underlayment would have stayed
in place is possible, I guess, but doubtful, IMO.

Yes, felt is waterproof. AFAIK, the essential part is to get the
tearoff, any repair, and then felt down fast, like one day, so
that it can then withstand the typical rain. It's supposed to be
good for at least a week or two. If I thought there was any
chance of going more than that, or expected higher winds,
heavy rain, etc before the shingles went down, then for sure I'd
use one of the more durable underlayments.

I'm sure this won't correlate to your details but I had my roof
repalced January 2011 and I live in SE VA.

The official sq. ft. of my ranch house is 1865, but I don't think that
includes the two car garage. I have a long roof, but it only has two
valleys and two peaks. Can't give you the amount of shingles used but
there was quite a bit left over which ****ed me off. The shingles are
GAF 30 yr architectural and the felt was all new of course. The total
cost was $7300. There was a crew of 3-4 Mexicans there for at least 2
days ripping up the old stuff, making minor repairs, taking out the
roof fans, and installing everything else, then cleaning up all the
bushes. They weren't goofing off either. The contractor was a local
well known one that matched the lowest invoice I had received from
others.

I'm sure this won't correlate to your details but I had my roof
repalced January 2011 and I live in SE VA.

The official sq. ft. of my ranch house is 1865, but I don't think that
includes the two car garage. *I have a long roof, but it only has two
valleys and two peaks. *Can't give you the amount of shingles used but

Thanks for the info. The roof is on an angle, so it's going
to be larger than the sq ft of the living space. And allowing
for the garage, the total could be more like 2700 sq ft.
That would be $270 a square. Also, I see online that there
have been several price increases over the last year or
two by the shingle suppliers. And, I'm sure there is still
a Sandy premium going on. So, my lowest quote of $270
doesn' seem unreasonable.

Have any of them quoted anything other than 15 lb felt?

I went with the GAF Lifetime system which included the WeatherWatch
leak barrier underlayment over the entire roof deck. See he

http://www.gaf.com/Roofing/Residential/Products

Regarding using a ice dam product on the entire roof,
I found guys arguing both sides of that one. *The ones
who seemed to have the science behind them, eg a
building sciences professor, were generally against it.

The proponents say:

it gives better water protection for the whole roof

Those against say:

it seals the roof, which is great to a point. *But sooner
or later some water gets in someday and with the barrier,
the wood can't breathe from the topside like it can with felt.
Moisture can't get out and the wood can rot. *Those in
favor of using it say the sheathing can still breathe and
dry out from the attic side. * Those against say, yes, that's
true, but it's better if it can breathe from both sides. *Those
in favor also say that with felt and shingles, the roof can't
breathe from the top anyhow. *The other side says yes it
can......

Bottom line for me is the existing roof lasted 28 years
with just felt, no ice dam stuff at all, no leaks, no problems.
So, I'm OK with just felt which is less expensive and less
labor intensive. *Two of the 3 roofers want to use the
ice dam stuff on the entire garage, which is low pitch.
Other guy says two layers of felt is better.... *Again, since
that's all that's there now, seems OK to me.....

My mistake. It wasn't the WeatherWatch that replaced the felt, it was
DeckArmor:

http://www.gaf.com/Roofing/Residenti...ck_Protection/...

When I was talking to the contractor and asked him about leaving any
section of the roof uncovered during the job, he said that they don't leave
for the day unless the DeckArmor is installed on any exposed decking. Per
the installation instructions, if installed properly, the DeckArmor can be
left uncovered for up to 6 months.

http://www.gaf.com/Residential_Roofi...tion/Deck_Armo...

The WeatherWatch was used only on the first 3 ft on the main sections of
roof. We have a fairly flat section of roof on a small addition. The
WeatherWatch was used on that entire section. Every contractor that gave me
an estimate recommended that for the flattish section.

Sorry for the confusion.- Hide quoted text -

The deck armor is apparently breathable, so it takes care of
that problem. *And a big advantage is that it can be exposed
to rain for months. * But since I'm going to have a dozen monkeys
doing the job in a day or two, that isn't an issue. *Now if I was
DIY, then I'd sure need it!

Just to be clear, the Deck-Armor wasn't used because of it's ability to be
exposed. It was used because it is required by GAF in order to get the
lifetime warranty on the shingles. My mention of its "exposibility" was
simply to point out that is must be much better (not sure that's the right
word) than standard felt.

I took a look at GAF's warranty and installation instructions for
their
Timberline shingles. Nothing there says you have to use their
underlayment.
They just give their products in the installation instructions as
examples
of underlayment.

I agree, it's much better if the roof is going to be exposed for
an unusual length of time with just the underlayment, like if it's
a DIY job. But I don't think it has much advantage when the
job is done in a day or two. I guess it might help if you have
extensive shingle blow off in a storm and the better underlayment
managed to survive. I just had that happen
with Sandy. I lost one large section of shingles right at
the peak, about 4 ft wide and 20 ft across. The felt went too.
Whether the more durable underlayment would have stayed
in place is possible, I guess, but doubtful, IMO.



The roof itself was done in 3 days, torn off and reshingled in two. There
was only one night when the roof, with the Deck-Armor installed, was left
unshingled. I assume even felt would have handled that. Do they leave felt
exposed over night? I don't know if I've ever seen that...could just be my
lousy memory. Tarps I've seen.- Hide quoted text -

Yes, felt is waterproof. AFAIK, the essential part is to get the
tearoff, any repair, and then felt down fast, like one day, so
that it can then withstand the typical rain. It's supposed to be
good for at least a week or two. If I thought there was any
chance of going more than that, or expected higher winds,
heavy rain, etc before the shingles went down, then for sure I'd
use one of the more durable underlayments.


Where I am in Texas, there were a lot of big homes with several
roofing companies doing re-roofs with complete tear-offs. I always
saw them doing the felt paper (underlayment) the same day as the
tear-off. I think I never saw any exception to this on the re-roof.
However on new homes, I've seen the plywood put on (completed) and it
may be days before they begin putting on the roofing materials.

I remember when I had a re-roof, they actually had a line item in the
estimate for the pitch of the roof.

Of course the essential difference is with new construction
when the roof sheathing is going up you don't have insulation,
sheetrock, fixtures or furniture in the house. So, any rain
that goes in, there isn't anything to damage.

The only advice I can give is to get several estimates and see if the
most reputable contractor will match it. It's imperative you do your
own homework to check for reputations and satisfaction of previous
customers. A one year subscription to Angie's List for this
information may be worth it.

Their website can be a bit tough to navigate, and it's inconsistent as
far as what information is included for each product, but it's my
understanding that you have to use one of the specialty underlayments
in order for the "system" to be covered by the Lifetime Warranty. The
Deck Armor is listed as the "Best" of the three he

http://www.gaf.com/Roofing/Residenti...eck_Protection

Here's where the inconsistencies show up...

If you click on the Deck-Armor product it will state "Deck-Armor™ roof
deck protection is a key part of the GAF Lifetime Roofing System".
The Tiger Paw and Shingle Mate products state the same thing on their
page.

However, it is only on the Shingle Mate page (the lowly "Good" of
their "Good-Better-Best" choices) where it specifically states the #30
felt is not covered by the lifetime warranty. Now, that may be because
the Shingle Mate product is the closest to felt and it makes no sense
to compare the Deck Armor or Tiger Paw to felt.

So I will agree that while Deck Armor is not required, the lifetime
warranty requires at least the Shingle Mate product at a minimum. In
other words, no felt, not even #30. What that tells me is that it is
not just an "exposure" issue, it's a long term performance issue.
Otherwise, why would they not give the lifetime warranty with #30
felt? I guess it could be so that they can sell their own
underlayments, but for the cost difference, I felt it was worth it.

BTW...you said that they were going to use #15 felt. If you Google
something like #15 vs. #30 felt, you'll find lots of hits leaning
towards #30. e.g.

http://www.contractortalk.com/f15/15-felt-30-a-7532/

Good luck!

When I was talking to the contractor and asked him about leaving any
section of the roof uncovered during the job, he said that they don't leave
for the day unless the DeckArmor is installed on any exposed decking. Per
the installation instructions, if installed properly, the DeckArmor can be
left uncovered for up to 6 months.

The WeatherWatch was used only on the first 3 ft on the main sections of
roof. We have a fairly flat section of roof on a small addition. The
WeatherWatch was used on that entire section. Every contractor that gave me
an estimate recommended that for the flattish section.

Sorry for the confusion.- Hide quoted text -

The deck armor is apparently breathable, so it takes care of
that problem. *And a big advantage is that it can be exposed
to rain for months. * But since I'm going to have a dozen monkeys
doing the job in a day or two, that isn't an issue. *Now if I was
DIY, then I'd sure need it!

Just to be clear, the Deck-Armor wasn't used because of it's ability to be
exposed. It was used because it is required by GAF in order to get the
lifetime warranty on the shingles. My mention of its "exposibility" was
simply to point out that is must be much better (not sure that's the right
word) than standard felt.

I took a look at GAF's warranty and installation instructions for
their
Timberline shingles. *Nothing there says you have to use their
underlayment.
They just give their products in the installation instructions as
examples
of underlayment.

I agree, it's much better if the roof is going to be exposed for
an unusual length of time with just the underlayment, like if it's
a DIY job. * But I don't think it has much advantage when the
job is done in a day or two. *I guess it might help if you have
extensive shingle blow off in a storm and the better underlayment
managed to survive. * *I just had that happen
with Sandy. *I lost one large section of shingles right at
the peak, about 4 ft wide and 20 ft across. *The felt went too.
Whether the more durable underlayment would have stayed
in place is possible, I guess, but doubtful, IMO.

The roof itself was done in 3 days, torn off and reshingled in two. There
was only one night when the roof, with the Deck-Armor installed, was left
unshingled. I assume even felt would have handled that. Do they leave felt
exposed over night? I don't know if I've ever seen that...could just be my
lousy memory. Tarps I've seen.- Hide quoted text -

Yes, felt is waterproof. *AFAIK, the essential part is to get the
tearoff, any repair, and then felt down fast, like one day, so
that it can then withstand the typical rain. * It's supposed to be
good for at least a week or two. * If I thought there was any
chance of going more than that, or expected higher winds,
heavy rain, etc before the shingles went down, then for sure I'd
use one of the more durable underlayments.

Where I am in Texas, there were a lot of big homes with several
roofing companies doing re-roofs with complete tear-offs. * I always
saw them doing the felt paper (underlayment) the same day as the
tear-off. *I think I never saw any exception to this on the re-roof.
However on new homes, I've seen the plywood put on (completed) and it
may be days before they begin putting on the roofing materials. *- Hide quoted text -

Of course the essential difference is with new construction
when the roof sheathing is going up you don't have insulation,
sheetrock, fixtures or furniture in the house. So, any rain
that goes in, there isn't anything to damage.


You're correct.
I was referring to the plywood decking of the new roof getting wet if
exposed. I don't like the idea of installing a new roof on wet
plywood (assuming it has not dried out days after rain/snow) but I
don't know if it could still dryout if the new roof was installed on
it. Perhaps others can educate me on this.

The roof decking will dry out from underneath. It will even dry out
somewhat through the breathable underlayment and shingles.

Google the matter and you'll find all sorts of discussions in construction
and roofing forums. Overwhelming consensus: While most roofers will do
their best to cover the decking as soon as possible, its not always
possible or practical. Wet roof decking is not an issue...unless you're the
guy that has to walk on it the next day. ;-)

BTW...covering the deck not only keeps the deck dry, but more importantly
in a re-roof situation, keeps the interior of the house dry. I have T&G
roof decking. A rainstorm on that deck would mean a lot water in the attic.

Thanks for the information !!
