If you’re about to get a roof replacement, you may have heard of the term “flashing.” Roof flashing is one of the vital aspects of the roofing system. However, not many homeowners know what it is or its purpose.
One of the most common causes of leaking, especially around the chimney, is improper or damaged roof flashing. According to the Federal Emergency Management Agency (FEMA), poorly installed flashing can lead to wood rot or deck collapse.
Keep reading to learn more about roof flashing, why you need it for your home, and how you can install it properly.
What Is Roofing Flashing Used For?
Roof flashing is a thin metal material, typically galvanized steel, that every roof needs to have. It is installed by professional roofers to direct and move water away from crucial areas of the roof, including chimneys, walls, dormers, or roof valleys.
These areas in your home are most vulnerable to leaks if they are not protected. A properly installed flashing will keep your roof airtight and waterproof.
This material also seals the outer envelope, protecting the inside of your home from the weather and other elements. Flashing allows water to run down the side and directs it to the shingles instead of going into the roof deck.
When you get a roof replacement, you do not necessarily need to replace your old flashing. It largely depends on your situation and the condition of the metal.
A professional roofing contractor can inspect your roof flashing for rusting and check the integrity of the metal. If they see that it is rusted or damaged, you will need to have the flashing replaced during your next roof replacement.
Roof Flashing Materials and Types
There are different materials available for roof flashing. Some of the most common types of metals include stainless steel, aluminum, copper, or lead.
Steel is typically the material of choice for roof flashing. It is malleable and corrosion-resistant, especially when galvanized. This material provides a clean look that suits most budgets.
If you want an upgraded aesthetic, copper is another good option. It is durable, lasting, and adaptable to changes in weather. Aluminum is lightweight and easy to form but must be coated when used with concrete and masonry.
Aside from materials, there are various types of roof flashing that you need to know:
- Continuous flashing: This is a long piece of metal that directs water down to the shingles. This type of flashing is also called “apron flashing.”
- Drip edges: The thin metal flashing helps water drip off the roof’s edges without causing a leak or damaging the home.
- Valley flashing: This metal flashing is placed on areas where two valleys of a roof join and form an angled dip.
- Base flashing: Two pieces of flashing are required by some roof features, like chimneys. This ensures that the whole system stays secure when the roof materials expand and contract due to weather changes. The base flashing is the bottom piece.
- Counter-flashing: This completes the two-piece flashing. Counter-flashing is placed above or opposite of the base flashing.
- Step flashing: This is a rectangular piece of flashing used for roof-to-wall flashing. Multiple parts of step flashing are installed in layers with shingles, ensuring that the water flows well away from the wall.
- Kickout flashing: This flashing guides water away from the wall and straight into the gutter.
When To Install Roofing Flashing
