I'm waiting on a quote from a local builder, but it's already leaning towards a LOT of money. Thinking I may have a go myself.

Thinking pressure treated lumber. Semi clear panels for the roof; need light to come through. The old panels are fiberglass, but checking places like Lowe's, suggests polyurethane is better? Anyway, if anyone has wisdom to share, please do so!
 
Check with a builder supply on the panels. They mostly deal with pros that know what they want so don't expect to play 20 questions at a builder supply store.
 
Within the hour, after posting this, the contract dude came back with a fair quote. I've got my Lowe's cart loaded with supplies, but now, it's not needed. Paying more than DYI, but that's okay.

Builder dude said the poly panels are good. More durable than fiberglass.

Another big check to be signed, but I knew this was coming, so it's okay.
 
You probably mean polycarbonate roof panels? I agree with skyactive - talk to local builders to find the best product for your climate (UV resistant, etc.). Polycarbonate requires you follow protocol for expansion/contraction, etc..
 
So, fiberglass is better? That's what's up there now. Thinking they must be 40 years old, or more.
If you have some that have lasted 40 plus, why not use the same thing again? At least keep that option on the table.

Plastic (poly) dries out, fades and warps. Not an enduring product in my book.
 
Looks like the polyurethane panels have a 15 year warranty. I'll do some more research, but many construction supply houses don't even stock the fiberglass stuff anymore.

I'm having the area with the white walls closed in properly, and converted into a laundry room. Currently, the washing machine is in the kitchen, and the drier on that porch. This house was built before laundry rooms were standard construction. Also, adding a utility sink.
