This January, we received a call from a commercial property owner with a flat roof that had developed a leak. This is a photo of the leak we found on an exterior wall in the area of a side-wall scupper drain. [![Just Leaks Jan blog photo 1](https://static.hsstatic.net/BlogImporterAssetsUI/ex/missing-image.png)](https://static.hsstatic.net/BlogImporterAssetsUI/ex/missing-image.png) This is one of those repairs we are often called out on after several unsuccessful repair attempts have been made by others, or the owners. The roof often deteriorates at the drains due to stress and the drains need to be re-sealed. Here you see the effects of the deterioration at the mouth of the scupper. [![Just Leaks Jan blog photo 2](https://static.hsstatic.net/BlogImporterAssetsUI/ex/missing-image.png)](https://static.hsstatic.net/BlogImporterAssetsUI/ex/missing-image.png) What also often happens, and is often not noticed is that there was not enough of a drip edge to stop water from back-flowing at the outer wall. This backflow can go into the building if the leader head clogs, or if the drip edge is not extended far enough into the leader head. If not repaired properly, the leak will continue, even if the drain is sealed at the roof. In the photo below, you’ll see what a complete and reliable leak repair looks like. [![Just Leaks Jan blog photo 3](https://static.hsstatic.net/BlogImporterAssetsUI/ex/missing-image.png)](https://static.hsstatic.net/BlogImporterAssetsUI/ex/missing-image.png) These photos show how we removed the old mastic and sealants, rebuilt the roof around and through the scupper, and extended the drip edge. This is an example of how, by having the experience to know what to look for, and by being thorough in investigating all of our leaks, we have a very high success rate in completely stopping leaks. We realize this article is a bit technical for people who are not roof enthusiasts like we are, but we wanted to clearly illustrate the steps we take when servicing roof leaks. Our years of experience with flat, industrial roofs help commercial property owners secure their buildings against water leaks that could damage the structure, furnishings, electronic equipment, or products located inside the building. If you are a property owner or business owner that dislikes losing money on their investments and believes in preventive maintenance, you can rest easy knowing that Just Leaks will do a complete and reliable roof repair. To learn more about our roof leak repair, roof maintenance, or roof waterproofing services, give us a call at 408-249-4646. We’ll be happy to help.
