 I think what happened was they looked at my roof and measured it, got the square yardage, and upgraded me to the textured shingle, which I believe might be a little heavier. And I think they looked at the six vents I had on the back of my roof, ordered those, and went with that. They never went in the attic. They never looked at anything. And now I've got a problem, and they're telling me they're going to charge me more money. And I just, I don't know.
