I will tell you about my roof.

I had roof damages by wind during Hurricane Danny in 1997. Some of the 4 year old shingle tabs were broken off. The rest of the shingles on the rear, west and east slope suffered broken seals.

The State Farm Cat Adjuster allowed a $250.00 roof repair. He argued, the shingles with the broken tabs would re-seal themselves. The amount of $250.00 allowed was for spot repairs of the broken tabs. A replacement of shingles on the affected slopes was not warranted and would be over kill of required repairs due to the damages suffered. As an adjuster, I did not want to do the big battle. 

I demanded him to submit exact repair method in writing and have his supervisor sign off on it. They did. It stated the tabs did not have leaves or wind blown debris under them and they would re-seal themselves. I had the shingles with broken off tabs replaced by performing spot repairs on the two slopes as instructed.

I left the broken seals to repair them as instructed in writing. They never did. I checked many times. They did remain in place and did shed water. In 2004, Hurricane Ivan blew them off and extensive damage to the interior occurred. My neighbor had a new roof installed, as a result of Danny and had no damages to the roof during Ivan, thus no interior water damage, no interior claim.

I now believe that if winds are strong enough to break the tabs loose from a roof more than 1 year old, the roof is damaged. It will not repair itself.

I do believe you can purchase roof cement in tube form and re-seal each lifted tab using a caulk gun. There is a huge labor cost to do so. It is not a roof Minimum repair. Roof shingles do not re-seal/repair themselves with the same integrity they possessed prior to the breakage of the seal.

Read all the expert reports you want. They may stick a little, not with the same integrity. The manual re-sealing described above will place the strength of the adhering of the shingles to a higher level than before. That is determined by applying common sense. This will exceed the pre-loss condition. The roof does not need replacement. It is less expensive than replacing the roof. I believe this to be an exceptional repair to broken seals to a roof during a wind event.

However, you do have to inspect very carefully to see if there are creases and cracks in the tabs from the lifting and waiving that occurred during the wind event after the seal broke.

I never believe a roof will repair itself.
