How to Fix a Leaking Roof from the Inside

May 9, 2023

A leaking roof is a common problem for homeowners, especially during heavy rain or snow. Water entering through the roof can cause damage to the structure of the house and lead to mold and other issues if not addressed promptly.

If you've noticed signs of a leak in your roof, it's important to take action promptly to prevent further damage.

In this blog post, we'll cover how to fix a leaking roof from the inside, including identifying the source of the leak, making emergency repairs, fixing the leak from the inside, and preventing future leaks.

Identifying the Source of the Roof Leak

The first step in fixing a leaking roof is to identify the source of the problem. Signs of a leak may include water stains on ceilings or walls, dripping sounds, or wet insulation in the attic.

To find the leak from inside the house, start by looking for any obvious signs of damage to the roof, such as missing or damaged shingles or a hole in the roof.

If you're not able to locate the source of the leak from inside the house, you may need to inspect the roof from outside.

How to Find the Leak from Inside the House

If you suspect that your roof is leaking but can't locate the source of the problem, there are a few steps you can take to find the leak from inside the house.

First, try to locate the leak visually by looking for any wet spots or water stains on the ceiling or walls. Trace the water stain to its highest point, which will usually be directly above the source of the leak.

Once you've identified the general area where the leak is coming from, use a flashlight to inspect the underside of the roof decking or the insulation in the attic. Look for signs of water damage, such as wet insulation or dark spots on the decking.

If you still can't locate the source of the leak, you may need to conduct a water test. This involves having someone on the roof with a hose spraying water in different areas while someone inside the house looks for signs of water entering the house. This method can help you pinpoint the exact location of the leak.

Inspecting the Roof from Outside 

If you're not able to locate the source of the leak from inside the house, you may need to inspect the roof from outside. Start by looking for any obvious signs of damage, such as missing or damaged shingles or a hole in the roof.

Look for areas where the roof may be sagging or where there are signs of water damage. Check the flashing around the roof vents, chimneys, and skylights to ensure they are properly sealed.

If you're comfortable working on the roof, you can also conduct a more thorough inspection by walking on the roof and visually inspecting the shingles and decking. Use caution when walking on the roof, and be sure to wear appropriate footwear.

Making Emergency Roof Repairs

If you're dealing with a leaky roof in the middle of a heavy downpour, you may need to make emergency repairs to prevent further damage to your home. To make a temporary patch to stop the leak, you'll need roofing tar, a putty knife, and a piece of plywood or plastic roof covering.

How to Make a Temporary Patch to Stop the Leak 

To make a temporary patch to stop the leak, follow these steps:

  1. Locate the source of the leak and remove any debris or loose shingles from the area.
  2. Use a putty knife to spread roofing tar over the leaking area, covering it completely.
  3. Cover the tar with a piece of plywood or plastic roof covering, pressing down firmly to create a seal. 

If the leak is too big for a temporary patch, or if you don't feel comfortable making the repair yourself, consider calling an emergency roof repair service.

Fixing the Leak from the Inside

To fix a leaking roof from the inside, you'll need to locate the source of the leak and patch the roof from inside the house. Start by removing any insulation from the area where the leak is located, using a flashlight to help you see.

Once you've located the source of the leak, use roofing cement and a putty knife to make a temporary patch.

Steps to Fix a Leaking Roof from the Inside 

To fix a leaking roof from the inside, follow these steps:

  1. Locate the source of the leak and remove any insulation or debris from the area.
  2. Clean the area thoroughly using a putty knife to remove any loose or damaged material.
  3. Apply roofing cement to the damaged area, using a putty knife to spread it evenly.
  4. Cover the damaged area with a piece of aluminum flashing, pressing it down firmly to create a seal.
  5. Secure the flashing in place using roofing nails or screws, making sure to cover the edges of the flashing with a roofing cement to prevent water from seeping in.

If the leak is caused by a damaged shingle or flashing, you may need to replace the damaged material. Remove the damaged shingle or flashing and replace it with a new piece, making sure to seal the edges with roofing cement.

Preventing Future Leaks

Regular inspection and maintenance of your roof can help prevent future leaks. Check your roof regularly for signs of damage, such as missing or damaged shingles or flashing, and repair any damage promptly.

Pay special attention to roof vents and other potential trouble spots, and make sure they are properly sealed. If your roof is old or showing signs of wear and tear, it may be time to consider a roof replacement.
