They are in fact Certainteed Custom Sealdon shingle. I just tossed the extra bundles in the dump truck last night (with permission) and found the logo--they weren't very proud of it. A quick read through the settlement site show that there's a good possibility that I could be eligible to file a claim for maybe $500-600. The claim for is a huge pain and it sounds like the fact that one side was torn off will probably mean I can't claim that side since you have to send pictures of the product installed, so now I'm down to $250-$300. To get that I'd have to take, print and submit a dozen or so pictures, go get a copy of the final building inspection from my township, ship them a complete, carefully removed shingle, and gather a bunch of other information. It hardly seems worth it.
Other next door neighbor and I were talking last night and she said the barn was built about up in 1995 because they put theirs up the same year. Their roof is in way worse put shape than mine and I'm wondering if they used the same shingle.
