Flashing: The Benefits and Differences for Your Home

Jul 20, 2018

You probably know that flashing is the metal material that helps keep water from getting in your roof, between your walls, or through your window openings. But, as a homeowner, you may not be aware of the many kinds of flashing available or their specific uses. Does it matter if you use step flashing or L flashing? What is reglet flashing? Here are some basic things to know before you talk with your contractor about your roof flashing.

What Is the Purpose of Flashing?

You might think roofing is the true superhero when it comes to preventing water from entering your home. But the truth is, flashing is the underappreciated sidekick. It isn’t specifically exciting or sexy, but it does an important job. Flashing is metal used at various joints, such as rooflines, chimneys, windows, and corners, to prevent water from getting under shingles and damaging the interior of your home.

Flashing is an integral part of the complete roofing process. Without it, or underlayment, the shingles wouldn’t be able to do their job successfully.

Different Kinds of Flashing and their Uses?

In its most basic form, flashing comes in three different types all with different uses.

  • Roof flashing: for use on the peaks and valleys of your roof, around chimneys and vents, or along the edge of the roof and wall.
  • Window flashing: for the edges around windows where water can find a way.
  • Deck flashing: for connecting a deck to your home to prevent water damage around that joint.

Of course, within each of these flashing categories there are tons of options based on material, manufacturing, style, and more. For example, you may need to know the difference between L flashing and step flashing for different aspects of your roof and wall configurations.

Reglet flashing offers builders another layer of protection for your home. A reglet is an added notch in the construction of your home which allows the flashing to be installed seamlessly.

One product, produced by the Atlanta-area manufacturer FryReglet, offers a variety of products based on your home’s structure including masonry, stucco, concrete and more.

Benefits of Flashing

The primary benefits of using flashing is to prevent water from getting between your walls through any of the typical entry points like roof joints, vents, chimneys, or windows and doors. This means the step is essential and shouldn’t be considered optional for your roof replacement or home build.

There may be different benefits when using different types of flashing. For instance, if your construction allows for reglet flashing, you will find that the method of install can prevent problems caused by other installation processes.
