That’s why today, we’ll share with you this immediate solution to a leaking roof. This temporary repair from our experts can help you a lot until you can make a more permanent solution.

Tools You Need for Fixing the Roof

Unlike most DIY on the internet, we will only use common tools and materials that you can see in every household. Our roofing specialists did this so most people can repair their roof from the inside, even without proper roofing tools or skills.

Here are the tools you need for fixing your roof from the inside:

  • Caulking
  • Scraper
  • Flashlight
  • Utility Knife
  • Rubber Gloves
  • Nail
  • 5 Gallon Bucket
  • Roof Patch (Tar)

Once you have those tools, you can then start fixing your roof. But keep in mind that we’re only showing temporary fixes. The only lasting solution to a leaking roof is a professional repair or replacement.

Find the Leaks

Finding the leaks in your roof is easy if it’s raining. There will be droplets of water, and that will point you where the leaks are. If it’s not raining, just look for water stains on your attic. The water stains are indicators of leaks in your roof.

In case there are multiple leaking spots on your roof, be sure to circle the areas with marking chalk. Doing this can also help you locate the leaks once you find a permanent solution.

Divert the Water

In case you find leaks in your roof while it’s raining, you must first divert the water– you can’t seal the leaks if there’s water in them because most roof patches aren’t working in wet conditions.

With that said, make sure to provide a path for the water to drain. The best way to do this is by sticking a nail into the hole. The nail will work like a funnel. It will make the water flow in a single direction. Be sure to place a bucket under the leak to catch any water that drains. After that, wait for the surface to dry before you seal the leaking area.

Seal the Leak

Keep in mind that sealing the leak is easy, especially if the area is dry. So if the leaking area is wet, be sure to do the method above or just wait for the rain to stop.

Once the area is dry, apply a large amount of the roof patch to the leaking part. Use a scraper or knife to spread it evenly. Also, make sure to cover the entire area.

After that, consider using a caulk to cover the edges and holes that appear in the area you patched. You can use your finger to ensure that the caulking is applied to the entire area.

Inspect Roof From the Outside

If necessary, check the roof from the outside to see its overall condition. If you see that your roof is nearing the end of its lifespan, be sure to replace it immediately. Using an old and damaged roof can only lead to more problems that are hard to fix. If the leaking doesn’t stop, there’s a high probability that it will rot woods in your attic. Not only that, but it can also damage your walls if the rot reaches your ceilings.
