4 Common Materials Used for Roof Flashings

As a homeowner, you’re probably familiar with the shingles on your roof, or whichever other roof type keeps your home dry and safe. Amidst these popular materials, however, is the less popular but equally important roof flashing material. Flashing is a necessary component of your roofing system and you can usually find it in the areas of your roof where two surfaces meet, such as between the roofing and siding or skylights. Its function is to keep these more vulnerable spots of your roof safe from the weather and put off the need for roof repair or replacement any time soon. Here are the four most common materials used for roof flashings to consider:

1. Galvanized Steel
If you have a metal roof, then galvanized steel would be the natural choice since it is also the same material used for the roofing system. This material comes with a zinc coating to make the flashing less susceptible to corrosion and withstand long-term exposure to moisture.

2. Aluminum
This material is durable, malleable and relatively inexpensive, compared to other flashing materials available. Thanks to its malleability, it allows for maximum fabrication, lending itself to tricky applications such as the chimney, valley, or base flashing. It is important to add a finish to aluminum flashing to prevent corrosion when it comes into contact with wood, concrete, or cement. This means that only expert roofing companies or contractors can work with this material to ensure a watertight seal.

3. Copper
This is arguably the most durable and eye-catching flashing material on the market today. Rather than develop rust from years of exposure to the elements, it forms a green patina that ages gracefully without affecting the look of your roof. Copper is compatible with most wood preservatives and requires no painting or other treatments, making it one of the most popular choices when it comes to roof flashing.

4. Lead
Lead is one of the oldest and most durable materials used for flashing, providing long-lasting protection from water. It is soft and easy to bend and remains strong despite expanding and contracting perennially with changes in temperature. In fact, lead is believed to last for more than 200 years.

Roof flashing is a crucial component of any roofing system and protects the smaller spots that shingles or other covering cannot entirely protect.
