Roof Flashing

What is roof flashing?

In this blog post, we’ll explain everything you need to know about roof flashing, including what it is, what it’s made of, the different types of flashing, and how it protects your home. By understanding the importance of flashing, you can take better care of your roof and prevent potential problems.

Roof flashing is a thin piece of metal underneath the shingles on your roof. Its job is to stop water from getting inside cracks or holes in your roof. That way, the water is directed away from the parts of your roof that are easily damaged by water.

Where should flashing be installed?
Flashing needs to be installed in specific places on your roof:
– Around chimneys
– Where the roof meets a wall
– In the low points where two slopes of your roof meet
– On-roof vents (like bathroom and kitchen vents) and skylights
– On the edges of your roof (the parts that stick out like eaves and rakes)
If these areas aren’t protected with flashing, they risk getting water inside and causing a leak in your roof.


Roof flashing can be made of different materials, such as aluminum, copper, or steel. Each material has its benefits.

Aluminum flashing is lightweight and easy to install. It is the most common type of metal used for roof flashing.

Copper flashing is flexible and can quickly bond with other roofing materials. It is also very durable and can last for a long time. If you want to make your roof look nicer, copper is a good choice.

Steel flashing is coated with a protective layer to prevent rusting. It is also very flexible and easy to work with. Steel flashing gives your roof a clean appearance and is usually affordable for most homeowners.


Do you know what flashing is? It’s a special material used to keep water from damaging your roof. But did you know that there are different types of flashing? Let me explain.
The first type is called Step Flashing. It looks like the letter “L” and is used on the walls and edges of the roof. This helps keep water from getting inside your home. Some people even choose fancy materials like copper for their step flashing to make their house look extra nice.
Another type of flashing is Counter Flashing. This is used with step flashing when brick or concrete walls are attached to the roof. It works with the step flashing to ensure water doesn’t sneak in.
Then there’s Apron Flashing. This flashing is shaped like an “L” and is used around walls or other parts of the roof that stick out. It keeps water from seeping into those areas.
Next up is Valley Flashing. This type of flashing is used where two sides of the roof meet in a valley shape. It helps guide water off the roof and into the gutters. This special flashing makes sure water doesn’t run down the wall. It directs it into the gutters instead.
Lastly, Drip Edge is flashing. This attaches to the roof’s edge and helps keep water from flowing back towards the roof. It ensures water goes into the gutters or off the roof’s edge.


Do you know why roof flashing is so important? It’s because it can prevent roof leaks and protect your whole house! When your roof leaks, it can damage not only your roof but also your attic walls, ceiling, and the inside of your home.

Roof flashing is specially designed to keep water from leaking into your roof. This helps to protect your roof and make it last longer. When water gets into your roof, it can cause damage to the wooden parts of your roof, like the sheathing, underlayment, trusses, and rafters. This damage can lead to your roof failing sooner than it should.

Roof flashing also protects the insulation in your attic. If your roof leaks, it can damage the insulation. This can be a big problem, especially in a cold climate. When the insulation is damaged, it can lead to the formation of ice dams on your roof. These ice dams can cause even more damage to your roof, like making the shingles deteriorate and the decking decay.


Do you know what materials are used to make up your roof? It’s not just about roof flashing. Many other materials work together to keep your roof strong and long-lasting.

Roof flashing is essential to protect your roof, but there are other materials you need to know about. Ten different materials make up your roof, and each one plays a crucial role in making sure your roof lasts a long time.
