we got it up in a relatively short time. My house has various heights on the roof line so it took a little patience to get it just right. The double stitch makes me believe it will last. We have already had  a light rain and to my surprize the rain didnt come though the fabric and it also didnt weight the sail down and create a pool. Our patio is now usable as we face direct south  and on a sunny day, could hardly stand the heat.  We can now eat outside and the dog beds are out there too. Highly recommend this product
