Here are some more common roof leaks. Below is another example of a Goo repair job. Please understand that no matter how much Goo you apply it’s still going to most likely end up like this. Repeated applications only means the cracked material is thicker than it was before. Whether it’s a 1/4″ thick or 4″ thick once it gets dry and brittle it will crack and it will leak.
This is a very common area for leaks. The seam at the top or even middle of a parapet wall. This seam was never flashed properly and never had a counter flashing installed. You need to mesh and mastic any seam on a parapet wall and then you should install a counter flashing like the in the image below.
Here we have a very nice counter flashing but the vertical seams are starting to go. This is where a good epoxy roof mastic will save the day. When experiencing roof leaks you need to do a careful visual with your eyes and physical inspection with your fingers. You need to test every seam. Even the slightest sepereation at a seam will leak,
To solve this issue simply clean the area, apply a thin coat of our Roof Mastic and then work in some roof mesh with a serrated rectangle trowel until the mastic starts working it’s way up through the mesh. Then apply another layer of mastic just so that the mesh is no longer visible. Keep the mastic to a minimum, use just enough to seal and cover the mesh. The mistake most people make is that they just get up on the roof and start slapping gobs of goo all over the place. More goo is not better and is usually worse than less goo. Try our mastic and mesh method, we think you’ll like the results. Here’s a good example of restoring a roof with a commercial roof coating the right way. When done like this you will get as much or more longevity as an entire new roof at a fraction of the price. Notice that all the seams are covered with mastic and then the coating is applied over that.
