Detecting roof leaks early is vital to preventing extensive damage. Look out for water stains on ceilings and walls, dripping water during rainfall, mold or mildew growth, and sagging or warped areas on the ceiling.

Immediate Actions to Take

Upon discovering a roof leak, it’s essential to take immediate action. Locate the source of the leak, implement temporary patching methods, and ensure gutters and downspouts are free from debris.

When the rainy season comes, we often find roof leaks. This will not only affect the environment inside the house but also cause some damage to the roof. So, when we find a roof leak, how should we repair it? Below, we will introduce how to repair a roof leak on a rainy day.

  1. Find the location of the leak

Before making repairs, we need to find out where the leak is. If you don’t know where the leak is, repairs will be impossible. There are many ways to find the location of a leak, such as looking for water marks on the roof or finding the source of water droplets inside the house. If you really can’t find the location of the leak, you can use a leak detection instrument to detect it.

  1. Fix the loopholes

After identifying the location of the leak, we need to repair it. Methods for patching vulnerabilities vary depending on the situation, but here are some common methods.

  1. Use roof patching materials

If the leak is relatively small, it can be repaired using roof patching materials. Roof repair materials can be purchased at building materials markets or online, and the prices are relatively cheap. When repairing, you need to apply the material evenly to the leak and wait for it to dry. It is important to note that before applying roof patching material, the area around the hole needs to be cleaned to allow the material to adhere.

  1. Use roof waterproofing coating

If the leak is relatively large or a pothole has formed, you can use roof waterproofing paint to repair it. The price of roof waterproof coating is relatively high, but the effect is relatively good. The method of use is also relatively simple. You only need to apply the waterproof coating evenly to the leak and pay attention to the thickness of the application to avoid applying it too thinly and causing water leakage. Also, need to clean the area around the hole before applying.

  1. Replace tiles or waterproof layer

If the leak is relatively large, or a pothole has formed, which cannot be repaired using roof repair materials or waterproof coatings, then the tiles or waterproof layer needs to be replaced. This needs to be handled by maintenance personnel because replacing tiles or waterproofing layers requires certain skills and tools.
