It`s not that it didn`t work as much as in my case I couldn`t use it as directed. This application isn`t that straight forward because it involves a vent that opens and closes. It would have worked if I wanted it to stay closed and not open. The problem is I need the vent to seal and still be able to open it when needed. The stuff worked well on the skylight and around the window seals. I`m going to use some of the left over greenhouse plastic and make a removable cover for the vent that should work. I wish they would vent the air to the sides in the first place ! shouldn`t have this kind of problems if it was made differently. Putting holes in a roof is just asking for future problems! That`s why I would never put a roof mounted swamp cooler on a house! they can be mounted in windows or even in walls so why set yourself up for problems with a devise that uses water on a roof?
