Why Do Roof Cracks Happen?

Roof cracks are a common problem, and if not fixed on time, they can lead to leaks and serious damage. Rain, heat, and daily wear make the cracks worse, causing bigger issues in the long run.

Here are some simple reasons why roof cracks happen:

• Weather changes: Hot sun, heavy rain, and temperature shifts make the roof expand and shrink, leading to cracks.

• Poor construction: If the roof is not built well or good materials are not used, cracks can appear.

• Old roof: As the roof gets older, it becomes weak and starts to crack.

• Too much weight: Walking on the roof or putting heavy things on it can cause damage.

• Water damage:  If water stays on the roof for too long, it can weaken the surface and create cracks.

How to Repair Roof Cracks: Step-by-Step Guide

Fixing roof cracks is important to stop leaks and protect your home from damage. If cracks are left open, water can enter and make the roof weak. The good news is that you can repair them easily with the right waterproofing products.

Here’s how you can fix roof cracks step by step:

1. Clean the Crack Area

 Before starting the repair, remove any dust, dirt, or loose material from the crack. You can use a wire brush or water to clean it well. Let the area dry completely before moving to the next step.

2. Choose the Right Waterproofing Product

Picking the right waterproofing product is important for a strong and long-lasting repair. Here are the best options from 20MCC:

• For small roof cracks: Use Cracksil, a crack filler that seals gaps and stops water from entering.

• For cement roof sheet crack repair: Apply Nanosil, a waterproofing solution that gives a flexible and strong coating.

• For concrete roof slab crack repair: Use Tigersil, which protects the roof from leaks.

• For cracked concrete roof tiles: Apply Metakrete, which strengthens the roof surface.

3. Apply the Waterproofing Solution

 Follow these steps to fix different types of cracks:

• For Small Cracks (Less than 5mm): First, fill the cracks completely with Cracksil. Make sure the material goes deep into the crack so that there are no gaps left. Once applied, let it dry for a few hours. After it dries, apply Nanosil over the area to add an extra layer of waterproofing. This will prevent any water from seeping in and keep the roof strong for a long time.

• For Large Cracks (More than 5mm): For bigger cracks, you need a stronger repair. Start by mixing Metakrete with cement to create a thick paste. Use this mixture to fill the crack completely. Make sure it is packed in properly so that there are no weak spots. Let it dry completely before moving to the next step. Once it is dry, apply Tigersil or Nanosil over the repaired area. This will give the roof extra protection against water and weather damage.

• For Roof Tiles: If a roof tile is cracked, the first step is to clean it properly. Remove any dust or loose pieces around the crack. Then, apply Cracksil to seal the gap. Spread it evenly so that the tile is fully covered. Once the crack is sealed, apply Nanosil over it. This will add an extra waterproof layer and make sure the tile stays strong and does not leak in the future.
  
  

4. Let It Dry Properly

Once the repair is done, allow it to dry for at least 24 hours. Avoid walking on the repaired area until it is fully dry.

5. Regular Roof Maintenance

To prevent future cracks, inspect your roof regularly and apply a waterproofing coat like Nanosil every few years. This will keep your roof strong and leak-free for a long time.
