Plus it has saved me from spending lots of money on roof repair. Thanks Leak Stopper!

Rated 4 out of 5 by from Works Well I used leak stopper to patch multiple leaks in my rental property. It works well, although I had to go back up and repatch a couple of spots. No more leaks though. I applied it with a trowell and my only complaint is that it gets messy. Wear gloves and old clothes and have some mineral spirits, etc handy to clean yourself up. Great product! Saved me a ton of money in repairs.

Rated 5 out of 5 by from Works like it should-from Christine in Florida With great frustration, I've been chasing a roof leak for 6 months. After a hard rain, a small drip would occur where my screen patio roof meets the chimney wall(dripping behind it). So I bought Leak Stopper and applied it to the narrow section where the chimney wall and shingled house roof meet. That didn't solve the problem so I coated the shingles 1 foot out from my previous work. I also covered the shingles around the cricket where the waters runs down. Doing this fixed it. I also used reinforcing fabric strips sandwiched between the layers of the roof patch. I used paint brushes from the dollar store and free wooden paint stirrers from Home Depot to get the product out of the can and apply to area. This product is very gooey and messy so make sure you wear protective gloves otherwise you'll be scrubbing your hands in the sink longer than you'd like. Goop hand cleaner helps.
