What Is the Purpose of Flashing on a House?

Flashing is usually thin and pliable, but that doesn’t mean it’s not strong and durable too. Builders will put strips of flashing at crucial intersections to direct water flow away from the house. So, you’ll find most gutter flashing around windows, doors, and foundations.

What Are the Different Types of Roof Flashing?

Just like there are many different types of gutters, there are also many different types of flashing. For example:

  • Apron Flashing: This is also known as continuous flashing because it uses a single piece of metal to direct water down the side of your house.
  • Step Flashing: With this type, you use a rectangular piece of flashing and bend it 90 degrees to sit flush with corners and angles.
  • Base Flashing: This kind is best where two flashing pieces come together for extra support.
  • Counter Flashing: You place pieces opposite the base flashing to create a watertight pattern with counter flashing.
  • Valley Flashing: This kind helps protect the nooks, crannies, and divots on your multi-faceted rooftop.
  • Kickout Flashing: Contractors use this type to connect spots where the step flashing ends, and the gutter begins.

You might encounter drip edges as well. That’s because drip edges help builders prevent water damage to the home due to unforeseen leaks and damage. But be sure to ask a roofer for more information about the materials and techniques needed for your house.

Should a Roofer Replace Flashing?

Usually, roofers will repair or replace flashing when they finish installing a new roof. So, you should never install new flashing over old flashing because it can trap moisture and cause water damage. Instead, pay for replacements when getting your gutters repaired.

How Do You Install Roof Flashing Gutters?

Installing gutters can be a challenge, so installing roof flashing may also require an expert hand. However, it might also depend on the materials you use and the configuration of your roof.

Plus, you don’t need as many tools to cut vinyl as you do copper, tin, or aluminum.

Does Flashing Go Over or Under Shingles?

In most cases, the flashing on your house needs to overlap the material covering your roof. So, that means it needs to go over your shingles. This is how you stop water from getting in between the layers.

For aesthetic purposes, some asphalt roofs lay flashing under the shingles. That way, people can’t see the seams. Then, roofers often cover the flashing with a course of shingle tabs to help hide it even more.

Is Roof Flashing Necessary?

Roof flashing is necessary, especially if you live in an area with lots of heavy rainfall. Meanwhile, flashing is corrosion-resistant and made from metals like copper, aluminum, or steel. It’s also thin, flat, and flexible to help roofers install it on different structures.

Without roof flashing, the shingles and underlayment on your home become vulnerable to moisture. Then, excessive humidity can warp the studs in your walls or damage your floors. So, yes, flashing is essential no matter where you live. But keep your gutters clean to ensure they always work correctly.
