The advantages of flat roofs are many; their modern appearance and easy installation are some of them. But when a leak occurs on a flat roof, things can get complicated. So, how do I fix a flat roof leak? The answer to this question requires both a careful examination and knowledge of the correct repair methods. In this article, we will discuss the causes of the leak, how to detect it, and repair methods in both natural and practical language.
Causes and Symptoms of Flat Roof Leaks
Roof leaks can have many causes. The most common of these are waterproofing materials that wear out over time. Flat roofs are designed with very little slope to ensure that water flows smoothly. This can lead to deposits, and prolonged humidity can lead to the onset of leaks. If you notice cracks, blisters or discoloration on the roof surface, there is a high probability of leakage.
I remember an incident that happened to us last winter. A friend of mine’s roof was showing just such symptoms. The drops from the roof had come down to the living room. It took a week for this situation to be realized because no one thought that the water coming from the ceiling was coming from the roof and not from a cracked pipe. That’s why it’s so important to recognize the signs of leaks.
In addition, irregular maintenance also prepares the ground for leaks. Leaf and garbage deposits on the roof can prevent the smooth flow of water. Therefore, it is necessary to regularly clean the roof and check the drainage channels. If you neglect these, it is inevitable that water will leak in during the first big rain.
Leak Detection and First Response
Detecting a leak exactly can sometimes be more complicated than you think. Because flat roofs cause water to spread on the surface, there may be a difference between the place where the leak is decayed and the actual source. You need to do a careful examination to understand which area of your roof is causing problems.
A simple method is to make a visual inspection. When walking on the roof, look for cracks, bumps, or strange-looking areas. Last summer, a customer noticed a space on his roof that looked like a “strange balloon”. This bubble was actually an area where water accumulated and forced the insulation. If you see something similar, this is definitely a problem that needs to be intervened.
You can do a water test for a more in-depth examination. By holding water to the roof surface with a garden hose, you can determine from which point the water is leaking from the inside. However, make sure that someone observed the leak inside while doing this test. A two-sided study will speed up the process.
Repair Materials and Application Techniques
Before starting the repair process, it is of great importance to choose the right materials. A waterproof membrane, a roof patch and a quality sealant will be your greatest helpers in this process. In addition, depending on the condition of your roof, you may need tools such as a spatula, roller or brush.
The first step to repair a small leak is to clean the surface. Completely cleaning the roof and determining the area where the leak is located is the basis of the work. Repairs made without a clean surface can result in failure in the long. Last year, a client of mine applied the patch without cleaning. The result? The leak came back in the first rain.
After cleaning, apply sealant to the area of the leak and carefully place the patch material. When applying the patch, make sure that the edges are completely closed. Otherwise, the waterproofing may remain incomplete. Gently press on the patch to make it stick well and allow the time it takes to dry.
Measures to Be Taken Against Future Leaks
If you want your roof to be durable for a long time, regular maintenance is a must. Check your roof at the beginning of each season and solve small problems immediately. Remember, a small crack can turn into a big problem over time. Recently, I saw that a leak, which could have been prevented with a simple cleaning, eventually forced me to replace the entire roof insulation.
Also, check your water drainage systems regularly. In particular, preventing the accumulation of leaves and debris allows water to flow freely and reduces the risk of leaks. Due to the non-sloping structure of flat roofs, this type of maintenance is much more important.
Finally, don’t forget to invest in quality materials. A roof that is properly insulated and covered with durable materials both reduces your costs and prevents leaks. If you do not want to have problems in the future, intervene in your roof in a timely and correct way.
