Suggestions on replacing patio's PVC roof panels
 
I have a small patio that was covered with transparent PVC sheets. I liked all the light they let in, but they are all broken and full of holes, so it's time to think about replacing them.

However, since I live in Texas, the sunlight that they let through heats up the room that is adjacent to them. I've been thinking about replacing them with either "tinted" polycarbonate sheets or galvanized panels.

What do you guys think? Is there something out there that I could do that would be a better option?

I'm up in Mesquite. I don't have quite the heat or humidity you have but I used opaque cover made from recycled material. No longer available.

Cant go wrong with metal, get long enough to cover without seams across roof; wasn't made in longer lengths, low slope and seams lead to leaks. Increase the side to side overlap by at least one valley and ridge.

Sound of rain on tin roof is peaceful, sound of metal withstanding typical Texas frog drowner or hail storm reassuring. Neighbors 40 year old tin roof has rusted to aesthetically pleasing color rich folks pay big bucks to match, no off color run off.

BTW put in more soffitt vents, one between the ones you have, push insullation away so air will flow.

When is non-humid time to visit San Antonio? That's why Alamo fell, everybody wilted. That and defenders had to run across street to use Walgreen's rest room. You'd think Daughter's would realize they should put in public restrooms.

They make different and better grades of polycarbonate panels now that would allow light in and last longer then your original panels. The galv. panels would cut out all the light from above and would be harder to install.

Going with solid steel panels will darken the rooms inside considerably. If you're into the "dungeon" look, you'll be happy. But plan on using the inside lights more than you do now.

You won't find much cheaper and easy to install like the product you have. It would have lasted longer if it had 1x4 straping under it.

notmrjohn, I had been considering galvanized panels, but I had been a bit hesitant because of what Precision Home Services and BridgeMan mention, the reduction of light. But, I could do with a little less light, since I have windows galore in that room. I'm a bit ambivalent about the light issue, actually.

nealtw, what do you mean by strapping? I tried to look it up but couldn't find it. Is that the wavy underside that keeps them in shape? Foam closure strips? If so, the polycarbonate that I'm looking into is not exactly wavy, it is more angular:
Suntuf 26 in. x 12 ft. Clear Polycarbonate Roofing Panel Would they still work?

But, one thing that galvanized panels have on their side is that they seem to be cheaper.

Thanks guys, since I didn't hear any horror stories from you, I'll assume that the choice is just up to taste :)

This type of roof needs 2x2 cross pieces to provide under-support for the panels. Downward pressure from rain flexes the panels and can cause premature cracking. I have seen this system with 2x2s at 12" o.c. held in place by deck screws.

Honestly, the junk on the roof obscuring the sunlight looks awful. I would rather have a galvy roof and a couple of small skylights or Solatubes for light. Durability plus light where you want it.

CallMeVilla, wouldn't that be taken care of by those cross pieces already there? See second picture.

I agree it looks ugly.

I found a pic of 2x2 strapping

Ah, that makes sense. Not sure if it's needed or just a best practice, but I'll try to implement this once I remove the old panels.
