well this week I been having siding put on my house, by a licensed contractor, (who is very reputable) that my father knows (He's an electrician)
So, I figurered he wouldn't have done it if it was wrong.
My neighbor was just having his roof done, this week, and that is what the guys doing his roof told him. They said they were talking to an "engineer", and he said that to be true.
Keep in mind, when i asked where he found these guys, that were working on his roof, he told me they frequent the bar that his girlfriend works at.
So, i always take what is told to me, with a grain of salt....a big grain
