Roof Leaks Part 3

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.

Roof Leaks Part 2

When you see or feel the first drips of water coming down from your ceiling or roof the first thing you tend to do is want to run to the store and buy a bucket of black tar to patch the leak. There are a few problems with this. First is the fact that where you see the water coming down is most likely not where the leak is occurring. So the first thing you should do is try to determine the source of the leak. This can be extremely frustrating and time consuming. Next thing you should do once you determined where the leak is from is figure out the best repair method.

Applying roof patch is great at first and looks like this when you first apply it.

And finally this starts happening

Then you get sucked into the never ending patch trap. You are continuously applying patch to various areas of your roof and even trying different patch products. Until you end up with a giant mess on your hands and a still leaking roof. Tar based patch or black goo products like we call them are great for temporary emergency leak stop. But they’re not made for longevity. Once the sun starts baking them they get brittle and crack. Most times the cracks are not plainly visible and you think the patch is still good when it’s not. So you either miss seeing the leak or you just pour more goo on the problem. This a problem cause eventually you will want to fix the leaks properly and permanently. But with all that goo up there it makes it much harder to do a proper repair job.

Keep the goo to a minimum and once it’s fully cured after a few weeks you can go over it with a permanent mastic or roof coating.

If your applying goo all over your roof and it’s still leaking it may be that the roof material has just worn out and is now porous and water is working it’s way right through the roof membrane. Most times it’s cheaper, faster and a lot less frustrating to apply a roof coating over your entire roof. Our epoxy rubber based Roof Coatings are super strong and will seal up porous roof materials, fill in invisible cracks and other leak causing issues. Our Roof Mastic is far superior to any goo you will put on your roof.

So in sum if your sure you have an isolated leak and have located it for sure, go ahead and patch it but at least use a high quality roof patch. If your leaks seam to be popping up in different places like the bump in a rug scenario. Don’t waste your time and money trying to spot fix it. Coat your entire roof and be worry free for the next 15-20 years.
