The Gaco roof product is a great for roofs in our area ... especially for flat roofs. The 100% silicone product allows it to handle ponding water better than other coatings. Since it is white or light grey in color, it allows it to help keep the house cooler than Wet Patch or BlackJack, which is black and draws the heat.
Boy, I'm not sure. I suggest you Google that product. If you do, there should be some reviews/ratings.
