Hello Thomas,
Thank you for your review and feedback. We are sorry to learn of your experience. As you have noted the Veranda covers have great water resistance, and to prevent the puddle on the top surface place a beach ball under the cover, or if you prefer, we have specifically made Duck Domes that fit under covers to aid in water runoff. Just type Duck Domes in The Home Depot search bar to locate these items. Thanks again for your review, we hope the cover provides protection for many seasons to come.
