Can you Repair Roof leak from inside

Do you have a leaky roof but don’t want to go up on the roof to deal with it? Don’t worry; you can still repair your roof from the inside. In this blog post, we’ll discuss how you can find and fix a leaky roof from the comfort of your own home. Read on to learn more!

Identifying the Leak

Once you’ve determined that a leak is present, the next step is to identify its source. As previously mentioned, this can be tricky as the underside of your roof may be obscured by insulation. When insulation deteriorates, it can help you find the source of the leak by providing clues. To help with this, take a flashlight and shine it around the area to check for areas of dampness. This can help you narrow down the location of the leak so you can then gain access to it and start creating a temporary fix.

Gaining Access to the Leak

Once you have identified the source of the leak, you will need to gain access to it in order to make a temporary patch. This can be done from the inside of your home, so no need to get up on your roof just yet. Depending on the location of the leak, you may need to remove some siding or panels in order to have access to it. If this is the case, make sure to use caution and be mindful of any nails or screws that could potentially cause injury. It is also important that you replace any cracked, rotted or missing siding, making sure the new piece overlaps the step flashing by at least 2 inches. Once you have access to the leak, you can then proceed with creating a temporary patch with plywood or shingles and applying roofing tar.

Creating a Temporary Fix with Plywood or Shingles

Once you have identified the source of the leak and have gained access to it, you can begin creating a temporary patch using plywood, shingles, and roofing tar. Start by removing the shingles down to the wood sheathing. Slip a strip of adhesive ice-and-water barrier (available where roofing repair supplies are sold) under the shingles.

Cut a piece of plywood to fit over the area and fasten it with galvanized roofing nails. Place a layer of roofing felt over the plywood and secure it with additional nails. Cover the felt with a layer of roofing tar, extending it a few inches beyond the edges of the plywood.

Finally, lay down some shingles over the tar and secure them with more nails. If done properly, this should provide you with a temporary fix that will keep your leak at bay until you can get professional repairs done.

Using Roofing Tar to Seal the Leak

Once you have identified the leak and gained access to it from the inside, you can repair it using roofing tar. Roofing tar is an adhesive material that can be used to seal any gaps or cracks in your roof. To apply it, get a putty knife and spread a liberal layer of tar over the hole.

Make sure to cover it completely, then place a piece of plywood or shingle over the tar in order to hold the patch in place. You can then spread additional adhesive material around the edges of the patch to ensure that it is properly sealed. Once done, check for any further damage or leaks, and make sure that the patch is doing its job before you finish up.

Applying Caulk or Roof Patching

Once the roof patch has dried, use caulking to cover the edges and gaps. Applying caulk or roof patching is an effective way of sealing off the affected area to prevent further damage. Make sure to use caulk or roofing cement specifically designed for outdoor use.

To apply the caulk, cut the tube at a 45-degree angle and insert it into a caulking gun. Run a thin bead of sealant along the entire length of the flashing, ensuring to fill all gaps and crevices. Allow the caulk to dry before testing it with a hose or bucket of water. If you have followed these steps correctly, you should have successfully sealed off any leaks in your roofing structure.

Checking for Further Damage

Once you’ve identified the leak, gained access to it, and applied a temporary fix, it’s essential to check for any further damage. This can include things such as shingle damage, broken flashing, and any other issues that might have caused the leak.

To do this, you’ll need to check the area around the leak and the area below where the leak was leaking. It’s also essential to check for any signs of mold or mildew indicating that water has been pooling in certain areas. If you find any of these issues, it’s best to consult with a professional roofer who can help you properly repair your roof.

Checking that the Patch is Working

Once you have patched the leak, it is important to check that the patch works. This can be done by running a hose over the area to test for further leaks. If you find any more, you may need to re-apply tar and caulk or use a roof patching product to seal the area further.

Additionally, if the patch requires nails for support, make sure to use galvanized nails that won’t corrode and cause further damage. Finally, keep in mind that even if your patch seems secure, you should still get professional repairs done as soon as possible in order to ensure your roof is safe and secure.

Storing Materials for Future Use

It is essential to store the materials used in the repair process properly, as they may be needed for future use. Tar paper and roofing cement, as well as any other materials used, should be kept in a cool, dry place away from direct sunlight.

Proper storage of these materials will help ensure that they remain viable for future repairs and can save you time when the need arises. Additionally, keeping a record of any repairs you have made can help you detect any potential problems before they become too severe.

Getting Professional Repairs

Once you have identified the leak and applied a temporary fix, it is important to get a professional roofing contractor to do the repair. A professional roofer will be able to assess the roof accurately and advise on the best course of action.

They will also be able to install any necessary flashing, shingles, or other materials to ensure the leak is permanently fixed. Professional roofers can also check for any further damage that may have been caused by the leak and make sure it is repaired. It is important to get professional repairs as soon as possible in order to prevent further damage to your roof and home.

Preventative Maintenance Measures

Preventative maintenance measures are vital to ensuring that any damage to your roof is minimized. Regularly inspecting your roof for any loose shingles, missing flashing, or other signs of damage can help catch any potential leaks before they occur.

If you find any issues, it’s essential to address them immediately. You may also consider applying a waterproof sealant or coating to your roofing material to protect it from the elements further. It’s also essential to ensure that your gutters and downspouts are clean and clear of debris so that water can be properly redirected away from your home. Taking these steps now can help you save time and money in the future.


In conclusion, repairing a roof leak from the inside is possible and can be done on your own. However, it is important to identify the source of the leak first so that you can adequately address it. Additionally, it is important to not only repair the leak but also check for further damage.

Lastly, if you are not confident in your abilities to repair the leak on your own, it is best to seek a professional roofer for help. With proper maintenance and regular inspection, you can avoid roof leaks in the future.
