Should You Add Roof Flashing to Your Home?

The roof of your home can last at least 20 years before it needs to be replaced. A well-maintained roof can last up to 30 years. One way to preserve its health is to add flashing.

The following is information about roof flashing, materials used, and the benefits of flashing.

What Is Roof Flashing?

Roof flashing is a material that contractors place on a roof to prevent the pooling of water. If you live in a geographic area that experiences a lot of rain throughout the year, this is a great roof add-on. The pooling of rainwater can occur even with one shower. It depends on the roof’s current condition as well as how often it is inspected. Flashing is usually made from galvanized steel. It is thin, and the flashing helps direct the water off the roof.

The pieces of material are placed around features such as the chimney, vents, and skylights. If the water sits over the plane that meets a wall too long, it can easily deteriorate the area. Water is absorbed by just about every material. Materials that do not absorb water usually rust, which results in a different type of damage. Flashing protects the meeting point between the plane and the chimney, for example. The water is forced to keep moving, and in the long run, you are less likely to see indoor leaks.


Flashes are available in several materials including:

  • Aluminum
  • Cooper
  • Steel

Steel is the most popular because it is fairly priced and stands up to the elements well. Aluminum is a good option, but it requires an extra step. To prevent corrosion, it should be coated. Copper is used on many roofs, but its color changes. There are plenty of homeowners who do not mind that the copper discolors into a patina.

Each flash has to be the correct size, otherwise, it will not do its job properly. This is one reason why you are encouraged to hire a trained, professional contractor to handle the job. Flashes are sold in standard sizes. That does not mean that your roof and the spaces that require installation are standard sizes, too. There may be a need for adjusting and cutting. You also have to be sure that any flashing added is up to code on a local and state level.

Benefits of Roof Flashing

Flashing is available in several types like:

  • Continuous
  • Base
  • Counter
  • Step
  • Skylight
  • Valleys
  • Drip
  • Kickout


Each type accomplishes a specific task. Continuous flashing acts like an apron. It carries water to the shingles below. Drip edges are great for preventing damage and leaks to the home because it forces the water to drip away from the walls.

Being a homeowner is no small task. In addition to paying off the mortgage, you have to worry about its upkeep. The roof is a vital component of your house, so it is a good idea to ensure it stays in good shape. Contact Steele Restoration for more information about roof flashing and how to make this decision.
