Double Wall Polycarb Roofing for Carport
I have a carport with 30 year old ripple fiberglass. It is in the usual state of moss and decay. The stuff is soft all over. I don’t like ripple, I like flat, and have seen double wall polycarb. I like the idea, but have no data on the stuff. Anyone have any experience with the product? It really has a clean modern look, but looks like I need joinery to make it work.

Here's a roof I worked on using that stuff. This was over living space and the builder made curved triangular skylights with it. It's been thru 2 winters and is holding up fine.
Looks great, easy to work with woodworking tools. I've seen some thicker corrugated stuff, but the majority of what I've seen is only ~ 1/4" thick and intended for glazing uses mostly, and wouldn't span far between rafters in a roofing application. Corrugation helps with that. You get snow where you are? The double-wall PC I've seen is expensive, but not nearly as expensive as 1/4" thick PC sheet. No idea on the cost for the thicker stuff, but you can expect it to be relatively expensive. Dunno what you'd do at the joints, since simple over-lapping on a pitched roof would probably not look the best due to the thickness of the material and the exposed corrugated edge. But who knows- that might suit the look you're after.
I've got corrugated clear PVC as my deck roof. I expected it to go yellow right away, but five years in an unshaded southern exposure and it's as transparent as the day I bought it. Not all that much more expensive than fibreglass and far more durable so far.
Aare you talkin about Lexan greenhouse type panels? They need a marrying strip to join two sheets, and foil tape on the edges that are open...I made a cover like a hatch for a real big area well type planter in a basement..cool stuff.
It can be hard on the wallet, but it is a neat look, and works fairly well. A local glass shop may be of help.
The stuff I am trying to refer to has a series of square tubes, it is about 1/2'' thick IIRC. 4x8, 4x10, and 4x12..I think.
