Water collects on top of this canopy and creates stress on the material.  You have to continue to push up on canopy to remove water.  Not sure if all canopies are made this way.  The product is beautiful and I do love my gazebo.  We called and explained the situation and received excellent customer service from Trixie. She ordered us a replacement no questions asked.  We had the gazebo less than a year so I am glad she could accomodate us.  Thanks Trixie!!!
