How to Fix a Leaking Roof From the Inside?

The roof is one section of your property that requires a high level of maintenance. Once it starts to leak, the roof can be fixed from either the inside or outside. On account of the myth that fixing a leaking roof from the inside is impossible, some homeowners seek outright replacement of their roof.

There are ways, including Do-It-Yourself methods, of fixing a leaking roof, but it takes the curious and skilled roofer to do this correctly and come out with a process that won’t end up creating more leakages in the roof.

So, rather than opting for or recommending a complete replacement, let’s walk through the best ways to fix your leaking roof. You’ll need to get some tools to carry out a successful fix on your leaky roof. They include the scraper, leak patch, bucket, caulking, and roofing tar.

Step 1: Look for the Leak

The first thing to do when you attempt to fix your leaking roof from the inside is to locate where the leak is. To start with, get inside the ceiling and trace the path of dropping water as it enters into the ceiling through the attic of the roof. You can go in with a flashlight in case the ceiling is dark. 

This process requires a lot of patience because the water sometimes travels some distance from the leaking points before dropping through the roof deck.  

The best result comes when it’s showering or dropping light rain. Otherwise, you’ll need to wait until the showers stop, and the leak area is dry. 

If you go by locating in wet conditions, you’ll have to divert the water. Diverting the water comes easy when you quickly put a nail into the hole from where the water drains. This helps you to channel the water into one direction where you can catch it.  

You can then remove the insulation from the ceiling before you clear the water from the various leaking points. Depending on the quantity of the drops of water, you can use a large bucket to catch the water.  

Step 2: Seal the leaking point with tar

To achieve the desired when sealing the leak, you must wait until the leaking point is dry. 

Waiting until the roof is dry helps you get the right leaking point and ensures the roof patch sticks on the leak. 

Now that you’ve identified the leak’s location(s), you can go ahead to make a temporary patch on the leaks. But just before then, you can use a piece of marking chalk to draw a circle around the leak. This will help you in a significant way the next time you’re ready for a permanent fixing of the roof.   

Doing the leak sealing requires pressing roofing tar on a piece of shingle or plywood. With the help of a knife, apply any of these materials to the leaking point. Please make sure the targets round the leaked patch, so it sticks firmly in place. To achieve maximum results, you can use a scraper to cover the entire leaking point and surround it with the caulking and ensure it evenly spreads.

Step 3: Inspect the Roof From Outside

Now that the leak is patched and covered with the caulking, the roof should be in good condition to continue to do the job of shielding your family from wind, snow, and rain.

Before descending from the roof, get out of the ceiling to examine the work you have just completed to see if it’s in order. In the process, you’ll have to check if there’s any part of the shingles, underlayment, or flashings damaged or affected slightly. Also, check for any wear and tear, as well as loose nails. Please take the opportunity to also clear the roof on any heavy foreign objects that have made the roof their home.

Frequently Asked Questions  

How can I locate a leak on my roof?

To check for leaks, the water meter is the best tool to use. To get an accurate result from this instrument, ensure there is no water being used in the house. Inspect that the leak indicator in the meter is moving. Alternatively, you can take a reading on the meter at an interval of 1 or 2 hours.

How much does it cost to fix a leaky roof?

What to do if I find a leak on my ceiling?

Seek treatment. It may require you to coat it with paint. Otherwise, you may have to replace the ceiling completely. It all depends on the extent of damage or leak.


Fixing a leak either from the inside or outside only offers temporary relief. It amounts to buying time and won’t do permanent replacement of the entire roof. Before you call the roofer or hire any professional roofing experts, you can apply this transient method to fix your damaged roof from the inside.   

Fixing your roof prevents further damage and unnecessary cost. It also reduces future spending if your roof has spent a relatively short amount of time on your property.

After all, a leaking roof doesn’t provide the comfort and protection that keeps your family out of the bad weather.
