Best Ways to Fix Roof Cracks – Tips and Techniques

Leakage is a very common problem associated with flat roofs. Water stagnates on roofs, leading it to seep through them, thus damaging the furniture and other valuables. A common reason for water leaking through the roof is the improperly installed waterproofing layer on the roof. But the major reason behind this is a damaged or cracked concrete slab. However, there are flat roof leak repair and techniques that can be used to fix the cracks on the roof to avoid leakage. Follow these steps to diagnose and resolve the issue of leaking roofs.

1- Inspection of Roof

There can be several reasons behind roof cracks and leakages. Therefore, it is important to determine the cause of the leak and to get it repaired to avoid problems in the future. Inspection of the roof before roof leak repair includes:

  • Looking for puddles of water
  • Pipelines inspection
  • Checking roof corners and drains
  • Inspecting the extent of cracks in the roof surface

2- Check for Leaks

If you’re trying to figure out possible areas for leaks, take a thorough look at the entire parameter. Check if anything penetrated through your roof and caused a possible crack. Objects penetrating through your roof cause cracks that lead to leakages. 

3- Check the Weather Forecast

If you are ready for roof leak repair in San Francisco, make sure you check the weather updates in your area before starting the repairs. Dry weather is preferred for roof repairs. This is because repairing a cracked roof involves the use of sealants, paint, and cement. These materials require dry weather to bond perfectly with the surface. So, if it is a rainy season, avoid roof repairs and wait for the sun to appear. 

4- Replacing the Damaged Tiles

Concrete slabs on the roof can deteriorate over time due to multiple reasons. They are exposed to harsh conditions of weather and hence are subjected to wear and tear. Cracks can also appear when you accidentally step on fragile roofs, which can also happen while repairing them. If the cracks are deep, it is better to replace the entire slab. Another common cause of cracks is exposed nails. However, they can be repaired by re-caulking.

5- Applying Roofing Sealant to the Crack

If the concrete slab is in good condition but still has minor cracks, it can be repaired. Although it is a bit challenging and may require a professional’s expertise, it is still achievable. Start applying the sealant to the cracks. Normally roofing putty is a very sticky element and generally black. Use a spatula and cover it properly with the putty. Evenly spread it onto the crack and cover the corners completely. Though this will make the area look messed up, it seals the crack perfectly. Let it dry for some days and check if the crack is repaired by putting water on it.

6- Sealant Reinforcement  

Available at your local hardware or home maintenance store, this product strengthens the sealant, making it as strong as or even stronger than hard roofing materials. But make sure that you are wearing rubber gloves as a precaution. Hold it in place by pressing it into the putty and covering the affected area. Start smoothing the product with your hand, so it doesn’t get tangled. Doing this step will get your hands very dirty, so wash them afterward.

7- Waterproofing 

The next step is to waterproof the repaired area of the roof. Any roof leak repair for a concrete roof must be completed by waterproofing the entire surface of the roof where the leakage is detected. Methods for a waterproof concrete roof:

  • Using a layer of Bitumen  
  • Installation of waterproof tiles and marble using waterproof seams
  • Use of waterproof layers 

8- Inspect the Roof from the Outside

Once you have repaired the crack and sealed it properly, the roof is in the best condition to provide shelter from extreme weather conditions like snow and rain. But, before you exit the roof, check what you have done from the side to see if everything is correct. In the process, you should check that some part of the tile, floor, or trim is undamaged or slightly damaged. Also, check the nail for wear and loosening. Moreover, remove any kind of heavy objects present on the roof as they can damage the concrete slabs. 

If your roof has cracks, it can cause many problems; therefore, they must be repaired as soon as possible. The leakage that can occur through a crack is very significant. Rain can drip through the roof and onto the floor when rain falls on the cracks. Hence, you must repair the cracks immediately. The best thing is that roof cracks are very easy to repair. Follow the above-mentioned steps to seal the roof cracks perfectly.
