Why Correct Flashing is Key to A Quality Roof

If you aren’t as familiar with the world of roofing, you might think that a roof is no more than wood and an assortment of shingles over your head. What you may not know is that roofing is much more involved than that. One of the most important things installed on your roof is called roof flashing. What is this key element and what does it do? Read through our guide below to find out!

What Is Roof Flashing?

Roof flashing is a thin layer of metal, typically aluminum, copper, etc., that your roofer will roll out on your roof then seals it before continuing with the rest of the components of your roof. Think of it as a protective layer that not only protects the people inside the house, but also protects the roofing materials.

Why Is Flashing Necessary?

So, what exactly does roof flashing protect you from? Well, the purpose of roof flashing is to divert water away from the materials on your roof that could be susceptible to water damage. The highest quality roofs have proper flashing installed in them, especially in areas where the roof meets a chimney, skylight, or other obstacles you might find.

What Are the Types of Roof Flashing?

Let’s discuss three types of flashing that roofers typically will use. Depending on what your roof looks like, and the different obstacles your roof has, a roofer may use any or all of the following types of flashing.

  • Continuous Flashing: This type of roof flashing is characterized by being a long single piece of metal that covers the whole roof. It passes water down to the shingles below and away from susceptible materials. Because it could have trouble with the changing nature of the house throughout the seasons, it is built with expansion joints so it can change with the house.
  • Base & Counter Flashing: This is a two-part flashing method that involves using two different sheets of metal to protect the roof. This type is often found with houses that have different features such as a chimney. The base flashing is the bottom piece, and the counter flashing sits next to or above it.
  • Step Flashing: This method sees the metal bent at a 90-degree angle, and is installed in layers, or ‘steps’ with shingles to ensure the water is diverted away. It is typically used for roof to wall flashing.

What Is the Purpose of Roof Flashing?

Overall, roof flashing is used to protect your roof, and in turn your home, from water damage. It uses sheets of metal to divert water away from some of the most susceptible areas of your roof.
