What is Garage Door Flashing

Garage door flashing is a seal that helps to keep water and debris from getting into the garage. The flashing is placed around the perimeter of the door and is usually made of weather-resistant materials such as aluminum or vinyl. Garage door flashing can be purchased at most home improvement stores.

If you’ve ever seen a garage door with a row of lights flashing across the bottom, you may have wondered what it’s for. This is called garage door flashing, and it’s a safety feature that helps prevent accidents. When a garage door is opening or closing, the sensors at the bottom of the door send out a beam of light.

If something breaks that beam of light (like a child or pet), the door will stop and reverse automatically. This prevents anyone from getting hurt by the door. Garage door flashing is required by law in some states, but even if it’s not required where you live, it’s still a good idea to have it installed.

It could save someone’s life one day!

What Does 4 Flashes Mean on a Garage Door Opener?

If you have a garage door opener with a flashing light, it typically means that there is a problem with the unit. The four flashes specifically indicate that the opener is not receiving power. This could be due to a number of reasons, including a blown fuse or tripped circuit breaker.

If your garage door opener is plugged into an outlet, check to make sure that the outlet is working properly. You may also want to check the wiring to see if there are any loose connections.

Why is My Garage Door Panel Blinking?

If your garage door panel is blinking, it could be for a number of reasons. The most common reason is that the opener’s photo eye sensors are misaligned or dirty. The photo eye sensors are responsible for sending a signal to the opener telling it when to stop and start.

If the sensors are misaligned, the opener will constantly try to close the door, thinking that there is something in the way. Misaligned or dirty sensors can also cause the door to open and close erratically. Another possible reason for a blinking garage door panel is that the opener’s circuit board needs to be reset.

This can often be done by unplugging the opener from the power outlet and then plugging it back in again. If this doesn’t work, you may need to replace the circuit board altogether. Finally, if your garage door won’t open or close at all, even when the panel isn’t blinking, then there could be an issue with your garage door springs.

Over time, springs can become stretched out or damaged, which prevents them from being able to properly counterbalance the weight of your garage door. As a result, your door may get stuck in one position or not work at all. In this case, you’ll need to call a professional garage door repair technician to fix or replace your springs as needed.

What Does 10 Flashes on a Garage Door Mean?

If you have a garage door opener with a photo eye sensor, 10 flashes on the opener’s light panel indicates that the photo eye is misaligned. The photo eye is a safety feature that ensures that there is nothing in the way of the garage door before it closes. If the photo eye is not lined up correctly, it will send a signal to the opener telling it not to close.

Garage Door Flashing Replacement

If your garage door is leaking water, it’s likely due to a faulty or damaged flashing. Flashing is the sealant that helps keep water out of your garage, and over time it can become cracked or worn down. Replacing your garage door’s flashing is a quick and easy way to fix this problem.

To replace the flashing on your garage door, start by removing the old sealant with a putty knife. Once all of the old sealant is removed, clean the area thoroughly with a damp cloth. Then, apply a bead of new sealant around the perimeter of the door.

For best results, use a caulk gun to apply an even layer of sealant. Finally, reinstall any trim or molding that was removed during this process. Once everything is in place, test your garage door to make sure it’s no longer leaking water.

If it is still leaking, you may need to replace other weather-stripping on your door or investigate another potential issue.

Chamberlain Garage Door Light Blinking Continuously

If you have a Chamberlain garage door opener, you may have noticed that the light is blinking continuously. This is not a defect in the opener, but rather a feature that is designed to indicate that the opener is in need of some maintenance. The reason the light is blinking is because the opener’s sensors are dirty or misaligned.

When this happens, the opener will go into what’s called “safety mode” which prevents it from opening or closing the door until the issue is resolved. To fix this, simply clean the sensors with a cloth and realign them if necessary. Once they’re clean and properly aligned, your garage door should operate as normal.

Liftmaster Garage Door Light Blinking Continuously

If you have a Liftmaster garage door opener, you may have noticed that the light on the unit is blinking continuously. This is actually a normal function of the opener and indicates that it is in standby mode, waiting for someone to press the remote control button to open or close the door. However, if the light starts flashing rapidly, it could indicate that there is something wrong with the opener.

For example, if the motor unit isn’t receiving power, the light will flash rapidly. If this happens, check to make sure that the unit is plugged into a working outlet. You may also want to try resetting the circuit breaker if your home has one.

If the light continues to flash after taking these steps, please contact customer service for assistance.

Aluminum Flashing around Garage Door

If you have a garage door, then you likely have aluminum flashing around it. This is because aluminum is a very durable metal that can withstand the elements well. It is also quite affordable, making it a popular choice for homebuilders and homeowners alike.

Aluminum flashing helps to keep water from seeping into your garage and causing damage. It is installed over the seams where your garage door meets the frame of your house. Over time, though, the aluminum can become dented or bent, which can cause gaps to form.

These gaps can let in water, which can lead to rot and other damage. To prevent this from happening, it’s important to inspect your aluminum flashing regularly and make sure that it is still in good shape. If you see any damage, then you should replace the damaged section with new flashing.

This will help to keep your garage dry and free from water damage.


If you have a garage door, then you know that one of the most important parts of it is the flashing. Garage door flashing is what helps to keep water and other elements from getting into your garage and damaging your belongings. Without proper flashing, your garage door could be at risk for serious damage.
