Step-by-Step: How to Find and Fix a Roof Leak

How to Find and Fix a Roof Leak

A leaky roof is already bad news, but if you are not able to find the leak, that is even worse. To be honest, roof leaks are difficult to find, particularly with low pitches or flat roofs. In this blog, we will not only guide you on how to find a roof leak but also give you tips on how to temporarily repair a roof leak.

How to Find A Leak In Roof?

Early roof leak detection can help avoid costly damages. For example, roof leaks can flood your living room and damage your furniture and personal belongings. Furthermore, water from the roof leaks can soak into your installation and start a dangerous mold growth started. So here are some tips on how to detect roof leaks.

Find the stain

At first, you will have to find out where the water is coming from. Most of the time, the leak starts at a single spot, so if you find the stain, you will be able to locate the water leak. If the area is wet, you can remove the damaged drywall or insulation. Once you have removed them, look for the source of the leak.

Look into the Attic

In most cases, you must go up to the attic to find out the leak. Look at the underside of the roof to find out signs of leakage. Make sure to check out all of the beams, particularly areas where two roof planes join. These joints are more prone to leakages. It is also a good option to look at the attic floor with a flashlight to find wet spots, stains, or signs of damage.

Carefully check the Roof

Once you have located the general area of the leak from the inside, it is time to visit the roof to inspect it from the outside. Take precautions and safety measures before going up to the roof. Check for missing or damaged shingles, problems with the structure, torn flashing, or mistakes in how the roof was installed. These are all causes of leaks.

Wet the Roof

If you are unsuccessful in detecting the leak, you will have to create fake rain. You can do one by putting a hose on the top of the roof and letting the water flow down. Or, you can ask someone to help you spray water on the roof using a garden hose.

Work on one part of the roof at a time to make leak detection easier. Start at the bottom and move from one side of the leak to the other. Make sure each section gets wet. While wetting the roof, keep an eye out for dripping sounds, puddles, and damp inside the house.

Taking off the Shingles

If all the steps mentioned earlier do not work, it is time to go deeper. Remove the shingles from the area you think the leak is and check the wood underneath. Plywood is known to absorb moisture, so finding the leak will not be difficult once the shingles are removed. Since you have probably already removed some damaged shingles by this point, you’re halfway close to repairing the leak.

How to Fix a Leaking Roof?

Before you think about fixing your roof, know that it is best to bring in a professional to do the job. Working without experience can make your leak a lot worse than it already is.
We will give some tips on how to fix your roof temporarily to pass the time until a professional arrives to either fix the roof or completely replace it in case of bigger damage.

If you plan to fix your roof leak, ensure the weather is dry. Don’t try to fix it while it’s raining or during bad weather. Instead, put a bucket under the leak to catch the water and wait until the weather clears up.

So now that you are ready to fix your roof, you will need a couple of 2/4 wooden planks and a heavy-duty polythene sheet that is large enough to cover the leak.

Here’s what you do:

  • Wrap one end of the plastic around a two-by-four and staple it in place. Then put another two by four next to it and staple them together like a sandwich. Do the same thing at the other end of the plastic.
  • Lay these two-by-four “sandwiches” along the bottom edge of your roof, and stretch the plastic up to the top, making sure to cover the leaky part completely.
  • Use more two-by-fours to weigh down the plastic on the other side, but don’t attach them to the roof.

This temporary fix will keep water and debris out of your house until you can get a professional to do a proper repair. It’s just a quick and temporary solution to prevent more damage until you can get a permanent fix.

Depending on your home insurance, you might need to do temporary fixes like this to show you’re trying to stop further damage until you can afford a long-term repair or replacement.

If you’re not sure about anything, it’s always a good idea to a trusted roofing company for advice.


Finding a roof leak and fixing can be tricky, but roof leaks are something that requires immediate attention, or they will cause more problems in the long term. If you are successful in finding the roof leak, try fixing it temporarily, as mentioned in the blog.

Remember, even though temporary fixes can give you some time, it’s really important to reach out to a professional contractor if you’re having trouble finding or fixing the leak. They know exactly what to do to solve the problem the right way and make sure your roof stays in good shape for the long run.
