Identifying the Leak
Table of Contents
Inspecting the Interior
When dealing with a leaking roof under shingles, the first step is to identify the source of the leak. Begin by inspecting the interior of your home, looking for any signs of water damage such as water stains, peeling paint, or mold. Pay close attention to ceilings, walls, and any areas directly below the roof.
Examining the Attic
Another important step in identifying the leak is to examine the attic. Look for any signs of water penetration such as wet insulation, water stains, or even visible water dripping from the roof structure. Note the location of the leak to make it easier to locate from the exterior.
Examining the Exterior
Once you’ve identified the general area of the leak from the interior and attic, it’s time to examine the exterior of your roof. Take a close look at the shingles in the suspected area and inspect for any signs of damage or deterioration. Look for missing or broken shingles, cracked or curled shingles, or any other visible issues that could be causing the leak.
Gathering the Necessary Materials
Before you begin the repair process, it’s important to gather all the necessary materials. Here are the key items you will need:
Roofing Cement
Roofing cement is a waterproof sealant that is used to repair and prevent leaks. It is an essential component when fixing a leaking roof under shingles.
Roofing Nails
Roofing nails are used to secure shingles and other roofing materials in place. Ensure you have an adequate supply of roofing nails to complete the repair.
Tarps or Plastic Sheets
Tarps or plastic sheets are crucial for protecting the work area from further water damage during the repair process. Use these to cover any exposed areas of the roof.
Caulk Gun
A caulk gun is used to apply roofing cement and other sealants effectively. Make sure you have a caulk gun on hand before starting the repair.
Putty Knife
A putty knife is a versatile tool that is useful for removing damaged materials, applying roofing cement, and smoothing out surfaces during the repair process.
Hammer
A hammer is needed for securing roofing nails and removing damaged shingles. Ensure you have a sturdy hammer that is appropriate for roofing work.
Utility Knife
A utility knife is essential for cutting roofing materials and removing damaged sections. It is a precise tool that allows for clean and accurate cuts.
Roofing Shingles
If the leak has caused damage to the existing shingles, you will need replacement shingles. Ensure you have enough shingles that match the existing roof for a seamless repair.
Roofing Felt
Roofing felt is a protective layer that is installed underneath the shingles. It provides additional waterproofing and reinforcement to the roof structure. You may need to replace damaged sections of the roofing felt during the repair.
Staple Gun
A staple gun is used to secure roofing felt in place. It is a quick and efficient tool that ensures the felt is securely attached to the roof.
Preparing for the Repair
Choosing a Dry Day
Before you start the repair, it’s crucial to choose a dry day for the project. Working in wet or rainy conditions can make the repair process more challenging and less effective. Ensure the weather forecast is clear and dry for a few days to allow the repaired area to fully dry and prevent further leaks.
Ensuring Safety
Safety should always be a top priority when working on a roof. Ensure you have the appropriate safety equipment such as non-slip shoes, gloves, and a safety harness if necessary. Take precautions to prevent falls and accidents by working carefully and avoiding any unnecessary risks.
Clearing and Protecting the Work Area
Before you begin the repair, it’s important to clear the work area of any debris or obstructions. Take the time to remove any loose shingles, nails, or other debris that could interfere with the repair process. Additionally, protect the surrounding area by laying down tarps or plastic sheets to catch any falling debris and prevent further damage to your property.
Removing Surrounding Shingles
In order to properly repair the leaking area, it may be necessary to remove the surrounding shingles. Use a putty knife and hammer to carefully lift and remove any damaged or compromised shingles. This will allow you to access the leaking area and ensure a thorough repair.
Repairing Roof Leaks Under Shingles
Applying Roofing Cement to the Leak
Once you have accessed the leaking area, the first step is to apply roofing cement to the leak. Use a putty knife or caulking gun to apply a generous amount of roofing cement directly onto the source of the leak. Ensure the area is completely covered and that the cement extends beyond the damaged area to provide a secure and watertight seal.
Replacing or Patching Damaged Roofing Felt
If the leak has caused damage to the roofing felt, it will need to be replaced or patched. Carefully remove the damaged section of roofing felt using a utility knife. Cut a replacement piece of felt to fit the area and secure it in place using a staple gun. If the damage is minimal, you may be able to patch the existing felt using roofing cement.
Securing Shingles and Nails
Once the roofing cement and felt have been repaired or replaced, it’s important to secure the surrounding shingles and nails. Use roofing nails and a hammer to carefully secure any loose or removed shingles back into place. Ensure the nails are driven in securely but not so tight that they damage the shingles.
Using Roofing Cement to Seal Shingles
To ensure a watertight seal and prevent future leaks, apply roofing cement along the edges and seams of the shingles. Use a putty knife or caulking gun to apply a thin bead of roofing cement along each shingle’s edge, overlapping as necessary. This will create a barrier that prevents water from seeping under the shingles.
Installing New Shingles
If the leak has caused significant damage to the shingles, it may be necessary to replace them entirely. Carefully remove the damaged shingles and install new ones in their place. Pay attention to the proper overlapping pattern and use roofing nails to secure the new shingles in place.
Applying Additional Measures for Flat Roofs
If your roof is flat or has a low slope, additional measures may be required to prevent leaks. Consider applying a waterproof roofing membrane or using roofing tape or sealant to reinforce the seams and edges. Consult with a professional to determine the best course of action for your specific roof type.

Dealing with Stubborn Leaks
Using Roofing Tape or Sealant
In some cases, the source of the leak may be difficult to access or repair. If traditional methods have not been successful, try using roofing tape or sealant to create a temporary or permanent patch. These products are designed to adhere to various roofing materials and provide an additional layer of protection against water infiltration.
Repairing Damaged Flashing
Flashing is the material used to seal and protect the joints and transitions of your roof. If the leak is originating from damaged or deteriorated flashing, it will need to be repaired or replaced. Carefully remove the damaged flashing and install new flashing using roofing cement and roofing nails. Ensure the new flashing is securely attached and properly sealed to prevent future leaks.
Applying a Roofing Membrane
For persistent or recurring leaks, applying a roofing membrane may be necessary. A roofing membrane is a waterproof barrier that is installed over the entire roof surface. It provides an additional layer of protection against leaks and is particularly effective for flat or low-slope roofs. Consult with a professional to determine if a roofing membrane is a suitable solution for your roof.
Consulting a Professional
If you have tried the above methods and the leak continues to persist, it may be time to consult a professional. Some leaks are more complex and require the expertise of a roofing contractor. A professional will have the knowledge, experience, and specialized tools to accurately diagnose and repair the leak. Don’t hesitate to seek professional assistance for stubborn or extensive leaks.
Preventing Future Leaks
Regularly Inspecting and Maintaining the Roof
One of the key ways to prevent future leaks is to regularly inspect and maintain your roof. Schedule routine inspections to identify and address any potential issues before they escalate into major leaks. Keep an eye out for damaged or missing shingles, deteriorated flashing, and any signs of wear or damage. Promptly address any repairs or maintenance needs to ensure the longevity and integrity of your roof.
Cleaning Gutters and Downspouts
Clogged gutters and downspouts can contribute to roof leaks by preventing proper water drainage. Regularly clean out your gutters and downspouts to remove debris such as leaves, twigs, and other obstructions. This will allow rainwater to flow freely off your roof instead of pooling and potentially causing leaks.
Removing Debris from the Roof
Debris such as branches, leaves, and dirt can accumulate on your roof and create a breeding ground for moisture and mold. Regularly clear away any debris from your roof to prevent water from seeping under the shingles and causing leaks. Use caution when removing debris and ensure you have the proper safety equipment to avoid any accidents.
Trimming Overhanging Tree Branches
Overhanging tree branches can pose a risk to your roof by scraping against the shingles and causing damage. Additionally, branches can provide an entry point for pests and facilitate the buildup of debris on your roof. Trim back any overhanging branches to minimize the risk of damage and prevent potential leaks.

When to Call a Professional
Extensive or Multiple Leaks
If you are dealing with extensive or multiple leaks, it is advisable to call a professional roofing contractor. They will have the expertise and resources to efficiently locate and repair all the leaks, ensuring the long-term integrity of your roof.
Roof is Steep or High
Working on a steep or high roof can be dangerous and requires specialized safety equipment and experience. If your roof has a steep slope or is at a significant height, it is best to hire a professional who is trained and equipped to work under these conditions.
Lack of Experience or Proper Tools
Repairing a leaking roof requires knowledge of roofing systems and specialized tools. If you lack the necessary experience or tools, it is better to leave the repair to a professional. Attempting to fix the leak without the proper knowledge and equipment may result in further damage and more costly repairs in the long run.
Safety Concerns

If you have concerns about your safety or are uncomfortable with the idea of working at heights, it is prudent to hire a professional roofing contractor. They will have the training, equipment, and experience to ensure the safety of the repair process.
Conclusion
Fixing a leaking roof under shingles requires a systematic approach to identifying the source of the leak and applying appropriate repairs. By carefully inspecting both the interior and exterior of the roof, gathering the necessary materials, and following proper repair techniques, you can effectively address the issue and prevent further damage. However, if the leaks persist or if your roof presents safety challenges, don’t hesitate to seek professional help. Remember to take preventive measures, such as regular inspections and maintenance, to minimize the risk of future leaks. With the right approach and attention to detail, you can maintain a leak-free roof that protects your home for years to come.
