Slide-out fabric

It depends on where you are. I had Carefree vinyl and they were replaced after a year (warranty) for ripping. After another year they were going again. I went to Shade Pro in El Cajon, CA and they suggested for longer life I should switch to acrylic which I did. The service and instal were great but after the first rain they pooled significantly. I tried using a long pole to lift the center of the topper up to remove the water (like I had done with the vinyl) without success. The acrylic is too light of a material. The acrylic would fill with water eventually extending down to rest on the top of the slide. Trying to bring in the slide to get the water to run off resulted in the acrylic material sucking in on top of the slide. I called Shade Pro to see if the material could be tightened. They indicated that pooling was common with acrylic as it was so light and acrylic was good for CA weather (sunny) but not for other places. I have tried "Air WEdges", pvc tubes etc to keep the toppers from pooling without success. After rain I need to go up on the roof and sweep them off. Next time I will go back to vinyl.
