Should I be concerned with their options? Stay away from certain lines?

I am getting siding, roof, and gutters replaced, and fascia boards wrapped in aluminum and new soffits.

First contactor I had out was a big local company, willing to do the job for my written SF estimate (~26k). They had booklets for Iko shingles and Market Square siding.

I also have a guy that lives around the corner who does construction, said he can get a crew together to do the job, and save me enough money to get the fascia boards and soffits done. He suggested getting materials from Menards. I'm just trying to do my research and make sure I'm not going to have issue with the products they sell, since it is a big box store, or at least pointed to a direction of which ones to use over the others. This guy has done work for me in the past, albeit a smaller drywall job, but he did great work for cheap ($500 total with materials to drywall my whole ~5x8 bathroom that reddit seemed to think should cost like $2k), so I'm not worried about his quality.

And for whatever it's worth, my house is not some fancy mcmansion, etc that I need the greatest stuff out there. It's a split level 1500 sq ft 2 BR (used to be 3) house. I'm not looking for best of the best, highest end stuff. I just need to get my hail damaged aluminum siding, gutters, and roof replaced... and honestly, if I put up the cheapest stuff I can buy, it will look 10x better than the house does now, but if I can get something middle of the road that will last longer, not fade, but without paying top of the line prices, that's the product I want.
