4 Most Common Metals Used for Roof Flashing

Flashing is an invaluable roofing component. Its job is to protect the most leak-prone areas, demanding it to be durable and resilient no matter what. However, its strength is only as good as the material used to create it. In most cases, metal is preferred, but which kind is the best?

4 Most Common Metals Used for Roof Flashing

If you ask Twin Rivers Roofing and Construction, here are some of flashing materials that the most weather-resistant roofing systems use:

1. Galvanized Steel

Metal roofs are typically made from galvanized steel, which is why it’s only natural to cut the flashing from the same cloth. The addition of zinc coating makes iron-containing steel less susceptible to corrosion, rendering it rustproof for a long time despite constant exposure to moisture. It’s perhaps the most affordable flashing option on the market.

2. Aluminum

The most desirable quality of aluminum is malleability. Although it can’t be soldered, it allows for maximum fabrication, lending itself to tricky applications. Any roof repair specialist would say that aluminum tends to be costlier than steel, but you could decrease your cost of labor with its ease of installation.

3. Lead

You might raise your eyebrows, but lead flashing is more likely to harm those working directly with it than those living in the home it serves. As a construction material, it’s an excellent barrier to anything, especially water. It’s flexible enough to remain intact despite expanding and contracting perennially with temperature swings. Known to last for more than 200 years, lead’s durability is unquestionable.

But then again, you ought to hire a qualified roofer to ensure safe lead flashing installation. Look for proof of insurance when hiring to protect yourself from any liability in case any worker gets hurt.

4. Copper

Copper flashing is usually used to match its parent roofing system. The superior mechanical properties of this metal are well-documented; it can outlive the most durable metals. It doesn’t share aluminum’s aversion to soldering, making it easier to create a watertight seal. Rather than developing rust upon years of exposure to the elements, it forms a green patina instead to age gracefully. Its cost may be the one of the highest on the market, but it’s worth the expense wherever it’s applicable.
