Flash Briefing: All About Common Roof Flashing Types

If you have a roofing job coming up in the near future, you need to be prepared with the right material. One of the most important materials is called flashing. Flashing comes in all shapes and sizes. It is important for directing water away from the roof, preventing water damage. One of the most common types of flashing is called Z flashing. What is Z flashing and why is it important?

An Overview of Z Flashing

Even though there are many types of roof flashing, Z flashing is among the most common. As the name suggests, this is a piece of metal that comes in the shape of a Z. It is important because it acts as a transition point between two different types of materials. Because of the specific shape of the metal, it creates a channel that can receive headwall flashing, ridge caps, and panels. Because this type of metal smoothens the transition between different materials, it prevents water from penetrating the roof. 

Remember that this type of flashing is often custom-made. Therefore, it should fit perfectly with the rest of the roof. Its profile, size, and angles should allow contractors to anticipate potential threats to the integrity of the roofing structure. 

Is Z Flashing Different from L Flashing?

There is another common type of flashing called L flashing. A lot of people believe that L flashing is the same as Z flashing. In reality, they are used in different ways. L flashing is usually employed to strengthen the finish on a surface with a 90-degree angle. L flashing protects the structure from moisture infiltration where walls meet the roofs. 

Those types of flashing do the same thing. They prevent moisture from infiltrating the roof. On the other hand, L flashing is usually used in areas with a 90-degree angle. Z flashing is used to protect areas with different types of angles. 

Use Z Flashing When Roofing Corners

If you are wondering how to apply Z metal flashing or Z bar flashing, it is important to use it when roofing corners. Outside corner flashing is particularly vulnerable because it is exposed to moisture on multiple sides. Because of the angles that are present, Z flashing will work well in this situation. You may even want to install a metal Z flashing drip cap to add some additional protection. 

Common Metals Used for Z Flashing

There are multiple types of Z flashing available. Some of the most common materials used to make a roof flashing roll include copper, aluminum, and steel. Copper flashing is particularly powerful. If you are looking for the most durable option for your Z flashing, consider using copper roof flashing. Do not overlook the importance of Z flashing, as it protects your roof from moisture infiltration.
