That part was a joke, John. The first part was advise - something you
frequently ignore but should really consider right now. Since you are
paying top dollar for your restoration you should know you might not be
getting the best they have to offer. While there are many high-quality
underlayments for roofs, I have never heard of MB Technology or Layfast
but what matters now is that it appears you are getting an application
with half of the available warranty. That might be OK for a normal
roofing job but, again, you are overpaying so you should get the very
best. Ask them about this:
* *Steep Slope (Limited Material Warranty):
*Layfast 10 year limited material warranty. One layer of TULF40,
TU35 or supercap SBS.

15 year limited material warranty. One layer of TU43.

This is very important:
*For Architects and Specification Writers
*Since Layfast is still mechanically fastened (like 30/40# felt), there
is no change in drawings/specifications. To specify Layfast, insert the
following language in the tile/shingle/metal roof specification section
where the underlayment is specified. For tile and metal roofs, we
recommend the use of TU70; for shingle roofs, we recommend the use of TU43.
Here's that warranty information:

Finally, the $80 per hour plus materials might add up to far more than
you ever imagined. Plywood, and lumber in general, is at an all-time
high. You could be looking at tens of thousands in extras and a lot
more if roof trusses were compromised by the water intrusion. If they
find mold they might stop the job until you can get that resolved. I
would recommend that you watch what they are doing, ask about the
underlayment warranty, and pay very close attention when they are down
to the roof substrate. Ask them to tell you when they discover
something that requires time and material and keep track of what
additional materials they are installing and how long it is taking
them. You already signed a contract but the open-ended part is where
they can really hit you.
