To challenge material misrepresentations of fact?  

So, here is the run down: First, I did pay to be a member of the "Multi-family investor Academy" as a online student and attended 2 conference calls and went into the web site and downloaded materials and read as much information that I had time to.

Are there material differences?

I like the idea of putting in better materials when there is a chance they might last.

That includes the material, installation, and finish work.

Some roofers might be looking for work now, next year they could be busy, so the cost will be more.Oil prices are going up, products made from oil base materials will go up, shingles are one of those products.

I did a lot of checking around and I was happy with the price and quality of the materials.
