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?
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:

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.
