Many roof flashings have a minimum thickness of around 0.7 millimeters to prevent water from penetrating a roof joint.

2. Weight

Each metal flashing can weigh up to 6.24 kilograms (6240 grams), depending on the material the manufacturer used.

3. Material

Roof manufacturers use galvanized steel to ensure the structure is tough and easy to maintain.

4. Finish

Many people use a plastic coating to ensure the flashing is rustproof to minimize water damage.

5. Angle

These days, metal flashings have an estimated angle of around 100 degrees to offer enough protection to roof joints. They ensure they remain dry even during the wet season to minimize the risk of rusting.

3 Materials Metal Flashing Manufacturers Use in their Industries

1. Copper

Firstly, some manufacturers use galvanized copper to boost corrosion resistance and prevent water leaks to roof joints. The beauty of copper is that it is durable, rustproof, and malleable, making it ideal for making metal flashings.

2. Aluminum

This lightweight material requires less maintenance and is relatively water resistant. Additionally, Aluminum is corrosion resistant, hence excellent for making flashings to safeguard your roofing system.

3. Stainless Steel
