Exploring the Types of Roof Flashing

Roof flashing is a thin material that surrounds different roof features. Its primary purpose is to divert water from critical spots, thus preventing leaks and damage. With the correct type of flashing, you'll protect the house from leakage and extend the roof's lifespan. Since there are numerous roof features, there are just as many roof flashing types.

Let's discuss the most common roof flashings.

Continuous flashing

This type is often called "apron flashing" because of its purpose. It is a single piece of metal that often features built-in expansion joints. That way, it can contract and expand with the house during different weather conditions.

Base flashing

Some roof features like chimneys need additional flashing to ensure protection. Base flashing is the lower piece in the layers. Installing flashing around chimneys can be very difficult, so combining two flashing pieces guarantees redirection of the water flow to the gutters. 

Counter flashing

This flashing type is placed opposite or above the base flashing. It is also the second component of the two-part team that completes the coverage.

Step flashing

Step flashing is bent 90 degrees in the center and shaped like a rectangle. It's usually used for roof-to-wall flashing, chimneys, or skylights. This flashing type has a step-like shape, hence the name.

Valley flashing

A roof valley is where two roof slopes meet. This section is one of the most critical spots of a roofing system when considering water accumulation. Valley flashing directs the water away from this area and towards the gutters.

Drip edges

Drip edges are thin metal flashings placed at the roof's edge that enable water to drip without leaking and damaging the house.

Kickout flashing

Also known as "diverter flashing," this flashing type acts as a bridge between the cladding and the gutters. When installed properly, they effectively prevent water buildup in critical places.

Vent pipe flashing

This flashing type covers the pipes on the roof.

Cap flashing

Chimneys, walls, and other flat areas use cap flashing. It diverts water in the opposite direction.

Skylight flashing

This type of flashing protects skylights. Some skylights come with it, while others require purchasing it separately.

Top reasons to hire roofing professionals

First, professionals have years of experience. Therefore, they can quickly determine the correct type of flashing for your roof. Moreover, roofing professionals use the proper procedures to guarantee excellent and long-lasting results.

They understand the risks of climbing on the roof and have the necessary equipment that keeps them protected. Plus, they obey all safety requirements.

Finally, many building codes and laws vary depending on the area. Professionals are familiar with them and will install flashing that matches the standards and fulfills all requirements.

Leave it to the professionals!

You may think hiring roofing professionals for flashing installation is a waste of money, but it's quite the opposite. Experienced, reputable experts will ensure the flashing is installed correctly and remain effective for years to come.
