We were looking at doing it to make our screened porch usable in winter (Georgia). My bro is an industrial designer and builds with it all the time. He said for our porch 12 x 16 angled roof the product alone would be about $3000. Add labor to that. And we'd have to switch our door. Total with his discount would be around $5,000.
He said for sure in summer we should take down and store. One concern was warping in heat (our upper sections are big) and the acrylic can become cloudy over time. Apparently there is very high end that should not get cloudy but that would not be in our budget.
We decided to spend that much and possibly have to replace in a few years was not worth it to us for just 4-5 mos a year. Right now we haven't decided if we want to make a permanent enclosure or maybe add a heater. I would for sure research types of plastic, issues with cloudy, warping, what is the best size for framing etc.
