Thought my bundles of shingles were stiff from being frozen together. Many are melted together...

Hurricane Irma removed most of the shingles and/or "weather proofing" from two Florida investment homes. That was last September by the way. Took four months for an estimate. Prices were almost double what I expected and contained several warnings about possible large cost overruns.
I was delighted when I found many pallets of Energy Star (solar reflective) shingles at Habitat Restore for less than 1/2 price. Most of the bundles did not flex. I figured they were frozen and appreciated the ease in handling stiff bundles. I bought 3 1/2 pallets....over 3000 sq. feet of premium three tab 50 year shingles.
Turns out that many, probably most, are somewhat melted together. Though it is possible that pressure did more to "glue them" together than ambient and solar heat melting shingle tar.
The shingles were exactly what I wanted from a quality, price, and energy star/reflective perspective. Being "melted together" will change everything of course.
Many times it has been possible to separate shingles that are a little melted together. Many times it is not possible, it is as if the tar has "set". I am hopeful that a very large diesel "garage" heater could be used to separate stuck shingles.

Roofing doesn't seem to attract folks who opted out of a doctorate in quantum mechanics. Good times.
FWIW, I suspect given heat, time, and a lot of patience, the heat welded shingles can be separated. A garage heater would probably melt me before the shingles though, so I'd probably have at it in a cool, well ventilated garage with a heat gun or similar point heat device.

1) Just started using a VPN. Fair chance that a contractors board would evolve into an Ingsoc hangout. Ingsoc, without a doubt, hates VPN's. They incapacitated my last VPN pretty quickly. This one costs more so....we shall see.
2) My only post was regarding a contractor that did not get paid by a single female. I commented that that particular group seems to be known for being a bit more challenging. The odds that Ingsoc would place a female in charge of a contractors board are excellent. All the best homes were built by females.
Heat seems to be known for making stuck shingles worse. A heat gun would also take forever, there are thousands of shingles. I am considering a propane powered weed torch. A 6" flame exudes a lot more heat than a 1500 watt heat gun.
I have found some that seemed to be glued together yet were only held together by, it would seem, high pressure. As if pallets were stacked on top of each other for a long time. I once bought a copy machine that did not use heat to apply ink to paper. It used pressure instead. If it is mostly a case of pressure bonding then I have a better chance than tar bonding.
The shingles were made almost two years ago. A lot of things may have happened.
The new forum software we have been using the last year or two, has been really good at stopping spammers. Only a small fraction get through anymore. I am not sure what they are using for their filters.

I cannot really say what happened in your case.

I'll bet a beer that a female with a graduate degree is in charge of the contractors forum. That would be completely in line with how neologic works. http://www.contractortalk.com/forum.php
There is no reason to ponder political affiliations either. We have no idea about theirs. And most people can get beyond pure political affiliations and talk about nut and bolt issues.
Don't take things too personal. It is easy to misunderstand intent behind forum posts. And humor is difficult to achieve with an international audience.

I know it's common to have the tar strip stuck to the other shingles. it's been easy enough in Missouri to twist the bundle after removing them from the wrapper. the wrapper helps hold them inn place. They have a fiberglass liner so generally they should pop apart. I know they could be well 'stuck' if they have sat in the Florida sun. but perhaps some a couple rows down won't be so bad....
Good luck to you!

I think pallets were stacked on top of one another for some time. Thus forming a compression type fuse. That would explain the significant curvature found in each bundle....the curves following the surface of the tabs on three tab shingles.
I may wish that I had not gone down this road. Already have several days invested in the project since I live about 225 miles from the place of purchase and have multiple trips invested.
I have a few weeks before departure. With good weather, I can work with each shingle and break down 74 pound bundles to ~50 bundles. At 59 years of age and a knee that flares up periodically, I would rather hump 50 pound bundles up a ladder. The old t-lock shingles were much easier to carry up ladders. In my prime I carried two t-lock bundles at a time. Though I was voted "Jolly Green Giant" of my esteemed high school.
Anybody interested in riding to S Florida and enjoying some fine S Florida weather? Roofing pays well. Riding.....not so much.
