    Does anyone have a copy of the report that was available years ago that explained wind lift of shingles with no cracks or other damages, just the seal was lifted, Have a contractor who wants to replace,  It explained that the shingle if not damaged would re seal, This was a wind claim, with no hail,

    John., I am not aware of this report. Each claim is based on its own merits. Wind can lift a shingle from its seal tab. If no debris, the tab should re-seal. If foreign debris gets on the sticky part of the seal, it will not re-seal. I have seen new shingles a year later that did not seal properly. This would be a product failure. This calls for a very close inspection of the tabs, not just a general inspection.

    As said, this is done on an individual basis.
    Success is not final, failure is not fatal: it is the courage to continue that counts.

    This is showing my age, but seal down tabs are only about 40 years old. I would look cross eyed at the roof or the roofer. If the wind pulls up a well sealed roof it will tear some of the tabs.. Me thinks they never were sealed. With a well sealed roof you need a putty knife to unseal , with out tearing.breaking.

    Chirp up Tony and Dave .

    Tom and Ray,

    Thanks for your help, let me explain a lil better. Multi story apt building, multi buildings. Some have had shingle loss due to high winds. On some, I was able to just pick one tab and a section of about five feet square would lift from the seal. No visual damages, Years ago I thought I (yep getting old) that I saw a report that this would not condemn the shingles and replacement was not required.  Just trying to get another view point, Again thanks so much,

    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.

    Tom, I am in complete agreement with you. The type of glue strip, once adhered is strong. Once the seal strip is broken, it can re-seal, but not with the original integrity and strength. There is a special glue on the market for sealing the shingles, which I usually allow if the seals are broken, yet the tabs are intact. I have never gotten a kick back on this allowance.
