What Is Window Flashing?

Water can be one of the most destructive elements to a home. Keeping it out is an important component of any new window system. Window flashing, sometimes called weatherproofing, if installed correctly is doing most of that heavy lifting.

Window flashing is an important term when it comes to window installation. Window flashing is a water-repellent material installed as part of your window unit to prevent water from seeping into your home. It’s used on roofing, chimneys and doors and other places that require a tight seal to keep water out. Flashing comes in all kinds of materials depending on where it is being used including rubber, steel and acrylic. In all cases it is thin and flexible to ensure it can be manipulated to a proper seal.

Window flashing is best thought of as a sealant around your window and is typically installed during your window’s original installation process.

If you’re unsure whether your window flashing was properly installed or it has been damaged, there are a few telltale signs that your flashing needs to be replaced.

Is My Window Flashing Installed Correctly?

Window flashing works similarly to shingles in the way it guides water downward. However, for this system to work, the layers must be positioned so that the upper layers lay down over the layers below.

During installation, be sure to see that the flashing is installed in the correct sequence. If the layers are simply laid over top of another, there is an opening created at the top, allowing for water to sink into your interior.

Resulting Damages

If you begin to notice water leakage into your home, or signs of water damage such as mold or mildew, it’s important that you have your window flashing investigated. An efficient sealant system makes a huge difference in whether water will penetrate your home. Replacing damaged or missing flashing is a good step to ensure that your window unit is waterproof without replacing the entire window. Window flashing could be damaged if your window is damaged in some way. If you are replacing a window you will likely be replacing the window flashing as well.
