Decra Metal Shingles

I looked over their website and was wondering if anyone has any other information on them. I have an inspection later in the week and this is what I am told is on the roof at this time. Any known issues, or things I should pay special attention to. Looks like a decent system, just would like to know if there are any known issues ahead of time. Thanks guys.

Practically impossible to walk without denting them.
