How to Repair Roof Flashing

Author: Rebekah Pierce

Roof flashing is an important part of your roofing system, and it’s crucial to make sure it is in good condition. If you notice any damage or signs of wear and tear, you should repair it as soon as possible. 

Here are some tips on how to do just that.

Repairing Roof Flashing

Roof flashing is an important part of your roof, and it’s essential to keep it in good condition. By following the tips below, you can learn how to repair roof flashing and keep your home protected from water damage.

Fixing Small Holes

Flashing is a common source of roof leaks, and small holes are one of the most common types of damage. Thankfully, repairing flashing and patching holes is relatively simple.

For flashing, simply remove the damaged section and install new flashing using nails or screws. Small holes can be repaired with an asphalt-based patching compound. 

First, clean out any debris from the hole and then apply the patching compound, using a putty knife to smooth it out. Once the compound has dried, simply paint over it to match the rest of the roof.

Replacing Damaged or Corroded Flashing

Over time, roof flashing can become damaged or corroded, exposing your home to water damage. While it may be tempting to put off repairs, it’s important to take care of the problem as soon as possible to avoid further damage.

First, you’ll need to remove the old flashing. This can be done with a utility knife or a circular saw. Be careful not to damage the underlying roofing material as you remove the old flashing. Next, you’ll need to measure and cut the new flashing to size. 

Once the new flashing is in place, you’ll need to seal it with caulk or another waterproof sealant. Finally, you’ll need to install any necessary fasteners to hold the new flashing in place.

Removing Old Caulk and Mortar

Over time, the caulk and mortar around your roof flashing can erode, leaving your home vulnerable to water damage. If you notice cracks or gaps in the caulking, it’s important to take action right away. 

The first step is to remove the old caulk and mortar. This can be done with a utility knife or a putty knife. Next, use a wire brush to remove any debris from the surface of the flashing. 

Once the area is clean, you can apply a new layer of caulk or mortar. Be sure to smooth it out so that there are no gaps or cracks.

Resealing Drip Edging

The drip edge is the first line of defense against water damage to your home. If you have any leaks in your roof, chances are that the drip edge is the problem.

Start by finding the source of the leak. Often, leaks occur where the drip edge meets the roofing material. Inspect the area around the leak and look for cracks or gaps. Once you’ve found the source of the leak, clean the area around it with a brush and soapy water. This will remove any dirt or debris that could prevent the sealant from adhering properly.

Apply a generous amount of sealant to the area around the leak. Use a putty knife or similar tool to spread it evenly over the surface. Allow the sealant to dry for 24 hours before allowing any water to come into contact with it. This will give it time to form a strong bond with the surface and prevent further leaks.

Maintaining Roof Flashing

Any homeowner with a bit of experience knows that maintaining a home can be a never-ending task. One of the most important parts of keeping a home in good condition is the roof.

Here are some steps to take to help you maintain your roof flashing – so no repairs are necessary in the future.

Prevent Ice Dams

As anyone who has ever dealt with an ice dam knows, they can be a real pain. Not only are they unsightly, but they can also cause serious damage to your roof. The good news is that there are a few things you can do to prevent ice dams from forming in the first place.

One of the most important things you can do is to make sure that your attic is properly insulated. This will help to keep the air in your attic cooler, which will in turn prevent heat from rising into the upper levels of your home and melting the snow on your roof. 

You should also make sure that your gutters are clean and free of debris. Clogged gutters can cause water to back up and freeze, which can lead to ice dams forming. Finally, you should try to keep the area around your home clear of snow and ice. This will help to prevent melting snow from running down your roof and refreezing at the eaves.

Inspect Flashing Often

Over time, the flashing can become loose or damaged, allowing water to seep in and causing costly damage. To avoid this, it’s important to inspect your roof flashing regularly and repair any damage as soon as possible. In addition, be sure to clear away any debris that could block the drainage holes in the flashing.

Remove Corrosion, Dirt, and Flaking Paint 

Take the time to remove any debris, such as leaves or sticks, that might be caught in the flashing. Next, use a wire brush to remove any dirt or corrosion that has built up on the surface. If there is any flaking paint, be sure to remove it as well.

Avoid Stepping On It

Although it is a durable material, roof flashing can be damaged by weathering, foot traffic, and debris. To help keep your roof in good condition, it is important to avoid stepping on the flashing and to clear away any leaves or twigs that could clog the gutters.

Be Careful About DIY Roof Repair

If you have a roof that is flashing improperly, it’s important to take care of the issue as soon as possible. Not only can improper flashing lead to water damage in your home, it can also be a safety hazard. 

The good news is that repairing roof flashing is usually a relatively easy process, and with the right tools and instructions, you should be able to do it yourself. 

However, it may not always be safe for you to do your own roof flashing repair – or even carry out your own roof inspections to make sure your flashing is in tip-top shape. In that case, you should call in the experts.
