WTF, have them tear off the old layer in that case.

3. Have the contractor do a new layer only.
4. ...
5. Profit.

Insurance Fraud...that's the ticket to profit...:roll:

Say he did that, and a couple of years later, a storm comes through and damages the roof. Since they paid for a complete roofing job that wasn't done...how do you think they'd deal with covering the damages?
Most likely, they'd deduct the amount they already paid to fix it the first time from any proposed payout...

It's not against code but I am not a fan of it. You also will have a shorter life on your second layer. Plus with a tear off you can replace any bad decking.

What he said, though in some places (like where I live) reproofs are not allowed.

I wouldn't expect any bad decking on a 15 year old house.

Mine was 17, and had 2 bad sheets that I needed to replace.

A second layer of shingles is very normal around the New England area.

It usually takes as long if not longer to strip a roof of existing shingles as it does to put a new layer down. Thus, if he's stripping and then re-shingling, it wouldn't be unreasonable for it to be twice the price of just re-shingling over an existing set of shingles.

You really shouldn't have any problems with the decking on a 15 year old house *unless* you've been missing shingles for a few months and the decking has been getting rained on a lot. In which case... well.. that's just your own fault for letting that happen. Get a tarp next time, or go put some shingles up yourself when they blow off.

It will cost you more in the long run. Removing two layers of shingle 10 years from now will cost you more than removing the shingles now and reshingling.

Whoever said tearing shingles off a roof is not hard has never done it.

It is important to realize that it is the felt paper under the shingles that prevents water intrusion. The shingles just protect the paper from the sun and wind.

If you do go with a second layer, have them put on the 30lb felt paper instead of the 15lb. The reason being that the paper is not going to lie perfectly flat, and every time the roof is walked, the new paper layers tears on the singles beneath it. The 30lb paper will hold up much better in this situation and costs only nominally more. Insist.

HUH? WHAT?, The shingles are the first line of defense to stop water intrusion. They do more than just protect the felt. The felt is only there to act as a vapor barrier not as a water barrier.

You are wrong. Completely and absolutely. I suspect clever marketing.

Also: I didn't read the part about the insurance. They only pay you for what you actually have done, so if they allow $X and you spend $Y hoping to pocket the difference, you will be unpleasantly surprised.

Payment under a replacement cost policy works as follows:

1. Inspection of damage to determine scope of the loss and cost of repairs. (Replacement Cost Value)
2. Initial settlement/payment for the Actual Cash Value of the loss (total cost less depreciation).
3. Repairs (generally this costs falls somewhere between the ACV and RCV.
4. Present invoice to insurer for completed work showing repairs totaled more than the ACV.
5. Insurer pays the balance of the repair work up to the RCV.

Amen.
Agreed.
We have four layers on our roof because they cheaped out.
Now it all has to be ripped off and replaced.

Incorrect as SphinxnihpS pointed out. The underlayment is (should be) a water barrier.

I just had my 20 year old shake roof replaced this week and had all this stuff explained to me. Got the 1/2"CDX plywood sheeting /#30 ASTM High-Performance Underlayment/Lifetime CertainTeed LandMark Premium high definition architectural composition shingles , looks very nice and cost me a cool 12G's. Fun!!

Plus dumpster rental of what, $250+ anyways to throw out the old shingles.
