3 Things to Know About Roof Flashing


Surely you’ve heard the expression “you haven’t seen rain until you’ve seen it from the inside of a house.” But that’s not what we want to talk about today. Instead, we want to talk about how your roof protects your home from water damage, and why flashing is so important for keeping out moisture.

In this post we’ll discuss, what is roof flashing, why is it important and what are common types of roof flashing.

What is roof flashing?

Roof flashing is a small, often decorative piece of metal or plastic that covers roof penetrations. It helps prevent water from entering the roof. Roof flashing can be made of many different materials, including copper and aluminum. Flashing is an important part of roofing because it protects your home from water damage caused by rain.

Why is roof flashing important?

Flashing, which is a type of roofing material that’s used to weatherproof the corners of a house, is important because it keeps water and moisture from entering your home.

Flashing prevents water damage by:

  • Protecting the roof from UV damage. That’s right—the sun’s rays can cause cracks in shingles over time, allowing water to seep through and into your attic or crawlspace. Flashing helps prevent this by covering the seams between shingles or tile pieces with metal flashing that’ll protect them from cracking prematurely.
  • Preventing leaks inside your home. Too much moisture can lead to mold and mildew growth as well as rot on wooden components like joists and subfloors—all things you want to avoid if you want your house standing strong for years on end!

What are common types of roof flashing?

Common types of flashing include:

  • Beaded metal. This type of flashing has a rounded shape that makes it easy to install over pipes or studs. It’s available in a variety of colors and finishes, including chrome-plated steel, bronze-plated steel, aluminum, and galvanized steel with a white finish for new construction projects.
  • Bent metal. Another common form of flashing is bent metal (also known as “bent sheet”). It comes in different thicknesses and can be preformed into many shapes by using clamps or other tools during installation to create custom shapes around pipes or penetrations on the surface of your roofing material. The more complex the shape you need to cover up with your bent sheet metal flashings, the more likely you are going to want it custom-made by an experienced professional who knows what they’re doing because this product must fit perfectly over each penetration hole without any gaps between its edges so water doesn’t leak through them onto your ceiling below where it might cause mold growth or damage other parts inside your home such as electrical wiring insulation.

Roof flashing protects your roof.

The most important function of roof flashing is to protect your home. This can be done by keeping water away from the house and preventing it from coming in through the roof. When water gets into your home through the roof, it can cause damage or rot, mildew, and mold growth.
