clear roof over patio
I would like some advice/help with the clear roof over our screened patio. We live in Calif. and have no issues with snow. About 10 years ago, We had our general contractor install flat clear panels from Tap plastics. The didn't hold up very well. A few years later, we switched to the corrugated panels that they sell in home improvement stores like Home Depot. I thought they were getting dirty, but after checking more closely, I realized that they are discoloring where the cross beams are underneath them. The plastic seems to be warping some too. It looks like I will need to replace them again but want to have something that is going to be more durable. I really want clear because this is off my kitchen and if we go with a solid roof, it will block a lot of the light. I love the airy feeling of the space, just can't seem to find anything that will withstand the intense afternoon sun. Please help with recommendations and advice as to what products will be more durable. Hopefully, the 3rd time's the charm and we won't be looking at this again in another 5 years!
