@@homesteadroofing 1 million packs of shingles would be 23,810 pallets. If you were storing this amount of pallets on a football field, you'd cover the entire field and stack the pallets 8 high.
I definitely think that there's some unethical stuff going on in the roofing industry. Prices were going up prior to 2021, but usually only once a year. When Lord Biden declares that we won't use domestic oil and shuts down our pipelines, then petroleum prices skyrocket and everything that relies on it. Now prices go up 3 - 5 times a year.
You can ask the roofer to show you the order invoice from the shingle supplier and then ask him to show you a label from the shingle bundles that get delivered to your house.
